Selleris Revenue Loop

A revenue system you own.
Built for your next stage of growth.

Selleris designs, builds and improves your revenue system on HubSpot for B2B SaaS and tech-enabled SMBs with mid-market ambitions, connecting data, AI agents, automation and reporting across demand generation, prospecting, sales, onboarding, retention and expansion.

Start with the constraint holding your growth back.

The diagnostic shows what each month of waiting costs you. Fixed price agreed before we start. No upfront Selleris delivery fee. No result, no invoice. You keep what we build in the diagnostic, whatever you decide.

The Problem

Your growth ambition has outgrown your revenue system.

  • Before the first conversation

    Buyers you never reach.

    When your expertise is hard to discover, buying signals go unnoticed and outreach depends on manual research, good-fit accounts can stay out of your pipeline. More activity is not the same as reaching the right buyers at the right time.

    Visibility
    Your expertise is missing from the searches, AI answers and comparisons buyers use to evaluate their options.
    Signals
    Website visits and relevant account activity remain disconnected from your CRM, prioritization and follow-up.
    Outreach
    Your team spends time researching and chasing accounts without a clear view of who fits, what changed or why now.

    The cost: missed conversations and time spent on the wrong accounts.

  • After the first conversation

    Value you never capture.

    Getting a conversation is only the beginning. Deals can stall without a clear next step. New customers can lose momentum during onboarding. Retention risks and expansion opportunities can surface too late. Your revenue system needs to connect what happens next.

    Conversion
    Customer needs, decision criteria and next actions are scattered across conversations, notes and individual memory.
    Onboarding
    The goals and commitments agreed during sales do not carry through into a clear path to the customer’s first value.
    Retention & expansion
    Account reviews happen mainly around problems or renewals, rather than observed value, changing needs and opportunities to grow.

    The cost: stalled deals, delayed customer value and missed opportunities to retain and grow accounts.

Waiting keeps the same constraints in place.
Where these gaps persist, so do the missed opportunities, manual work and avoidable costs. The question is which improvement is worth making first and what another month without it means for your business.

Start with the constraint. Not another tool. Our free diagnostic uses your business context and available data to identify the priority constraint, assess the cost of leaving it unresolved, and recommend what to build first.

The System

One loop.
The full customer lifecycle.
HubSpot at the center.

Selleris Revenue Loop connects how you attract, engage, win, onboard, retain and grow customer accounts. Shared context, data, AI agents, automation and reporting support the journey, whether customers buy through self-service, sales conversations or both.

  • Demand & prospecting Engage the right accounts.

    AEO research and content, visitor identification and relevant signals connect to account research, prioritization and outreach. Replies and customer context reach the people responsible for the next conversation.

  • Sales & onboarding Connect the sale to first value.

    Discovery preparation, deal context and follow-up support the buying decision. Agreed customer goals and commitments carry into onboarding, with clear owners, milestones and visibility into delays.

  • Retention & expansion Keep customer value in view.

    Connect adoption, service history and value evidence to account reviews. Surface retention risks and relevant new needs, prepare renewal and expansion actions, and route decisions to your team.

HubSpot at the center. Your systems connected. HubSpot connects the data, workflows and reporting needed for the agreed scope. Your existing CRM, product, billing and support platforms can remain in place, with integrations defined around the actual use case. Custom agents run in your Azure tenant where needed. We define and integrate the relevant product events; your product team or existing contractor implements the product-side changes.

Agents assist. You control the actions. Agents begin with research, summaries and drafts. Autonomous execution is enabled only for explicitly agreed scenarios and permitted actions. Exceptions and decisions outside those permissions go to a responsible person.

The full architecture. Your priorities first. The diagnostic determines which capabilities to build first. You do not have to commission the entire system at once; expanding the target-account base and further improvements are scoped separately. Selleris builds and improves the system. Your team runs day-to-day revenue operations.

The parts, explained: answer engine optimization, visitor identification, AI agents, RevOps, HubSpot implementation.

The Program

From growth ambition to a working system.

Start with a free diagnostic. Agree the initial Build, verify results as we deliver, and shape the next improvements around what your business needs.

  • Free. 10 calendar days

    1. Diagnose

    Once the agreed minimum data and access are ready, we review your customer lifecycle, investigate the priority constraint and develop a focused proof of concept. You get an evidence-backed recommendation for what to build first.

  • One scope. One total price.

    2. Agree the plan

    Review the proposed results, their forecast financial value and the total fixed price together. We agree one initial Build, with explicit assumptions, dependencies, completion criteria and result-linked payments. No upfront fee for our work.

  • Designed and built for you

    3. Build the system

    We design, engineer and implement the agreed capabilities in your environment, with visible progress, documentation and training. Your team gets a system it can operate, not a collection of tools to connect itself.

  • Evidence before payment

    4. Verify each result

    As each agreed result is achieved, we provide the completion evidence and the corresponding invoice. Payment is tied to that verified result, not hours spent, a calendar milestone or an unproven revenue forecast.

  • Further work agreed separately

    5. Improve

    After launch, we stay involved through value reviews and recommendations. Support, calibration and new capabilities are agreed separately, based on observed needs and priorities. Your team runs the system; no automatic retainer follows.

Diagnose: the Free Revenue Diagnostic

Free. 10 calendar days from agreed data and access readiness.

We start with your growth goal, sign an NDA and arrange the relevant data and official HubSpot partner access. No HubSpot yet? We help you create a free account in your name. You join the kickoff and findings discussion; we lead the research.

You get a decision brief you can hand to your CFO or board: the results, their forecast value, the assumptions and one fixed price.

  • A focused assessment. A high-level review of your customer lifecycle, with deeper investigation of the priority constraint.
  • A practical proof of concept. Useful research, business-context work or a functional demonstration, with its scope and limitations made clear.
  • A decision brief. Evidence, the cost of delay and a recommended next step. Where a paid Build is justified, proposed results, forecast financial value and total price are presented together.
  • Findings you keep. The diagnostic and included proof of concept carry no Selleris fee and no obligation to purchase further work.

Agree: one plan, clear commitments

Fixed total price. No upfront Selleris delivery fee.

We recommend one initial Build around the priority constraint. The proposal is valid for 30 calendar days from delivery. Once both parties sign, we reserve the agreed team and start window.

  • Defined scope. What the initial Build includes, what it excludes, the delivery schedule and the dependencies on your team or other providers.
  • Value and price together. Expected results and their forecast financial value, with explicit assumptions, alongside the total fixed Selleris price.
  • Result Cards. Completion criteria, the applicable Definition of Done and a verification method agreed before work begins.
  • Result-linked payments. Fixed payment amounts tied to achieved results within the total price. Software, credits and cloud costs are disclosed separately.

Build: a system your team can use

Capabilities and delivery dates agreed for your business.

We lead business and process design, engineering and implementation, reusing valid diagnostic work. The agreed scope determines which capabilities below are included. This is not a standard bundle.

  • A usable data foundation. Business context, enrichment, segmentation and explainable scoring for the agreed existing lead and customer base.
  • Connected capabilities. The commissioned agents, automations, integrations and reporting, built around the relevant parts of your customer journey.
  • Customer context carried forward. SPICED by Winning by Design connects why customers buy, the value they expect and what happens next across the relevant workflows and handoffs.
  • Operational readiness. Documentation, access and role-based training for the capabilities your team will operate.

Verify: the result, not just the work

Verification as results are delivered, not only at the end.

Each result is checked against the criteria agreed before work began. A successful setup test does not replace a separately promised output volume, time saving or operational improvement.

  • The agreed result. A completed asset, working capability, resolved problem or measured improvement, verified within its defined scope.
  • Accessible evidence. Tests, observations or measurements showing which criteria were met, under the agreed conditions and over the relevant period.
  • Completion requirements met. The applicable documentation, access and handover conditions completed alongside the result.
  • The corresponding invoice. Completion evidence accompanies the fixed payment allocated to that achieved result. Specific discrepancies follow the agreed review and correction process.

Improve: keep the system aligned with growth

Ongoing relationship. Further work agreed separately.

Your team runs day-to-day revenue operations. We stay involved in reviewing value and identifying what should improve next. The system, data and delivered assets remain under your control.

  • Continued value reviews. Around relevant business events and at least quarterly, including when no paid Improve work is active.
  • Prioritized recommendations. Based on your goals, observed performance, changing customer needs and the next constraint worth addressing.
  • Separately scoped work. Support, calibration and new capabilities are commissioned explicitly. Value reviews do not include unlimited technical support.
  • The same commercial principles. Agreed results, fixed prices and payment after achievement. No automatic retainer or repeat charge for an already delivered result.

The Glass Box standard

See the work. Verify the results.
Own the system.

You should not have to choose between trusting your delivery partner and being able to check the work. The Glass Box standard makes the scope, progress, costs and completion evidence visible while you retain control of the system.

The shared delivery plan lives in Selleris Connect, our client collaboration portal, so you can review progress, budget and approvals between meetings.

The Glass Box standard
What you can verify The Selleris standard
Work you can follow A shared delivery plan shows the agreed work, owners, deadlines and progress. You can review the build between meetings, not just through a monthly presentation.
A price agreed in advance One defined scope and total fixed price, with payments tied to specific results. Changes to the scope and price require explicit agreement.
Control of your data Your revenue data remains under your control in the agreed client-owned systems. Access to confidential information follows the NDA and the permissions needed for the work.
A system you own You control the accounts and delivered assets, with ownership and access documented. You do not have to buy ongoing Selleris services to retain access to the implemented system.
Direct provider billing Software, credits and cloud usage are disclosed separately and paid directly to providers. Selleris adds zero software markup.
Clear responsibility Selleris leads design, engineering and implementation. Your team runs daily revenue operations. Client and third-party dependencies are agreed before delivery.
Results you can check Completion criteria and verification methods are agreed before work begins. Payment follows the achieved result, supported by accessible evidence, not a forecast presented as an outcome.
Documentation as we build Documentation is created alongside delivery and stored in your workspace. The agreed handover includes the access and guidance your team needs to operate the system.

A fixed price.
Payment after verified results.

Your initial Build is scoped around the constraint worth solving first. The free diagnostic brings together the proposed results, their forecast financial value and one fixed total price, so you can judge the investment before you commit.

Agreed before we start. You commission one defined initial Build. We agree the scope, completion criteria, delivery schedule and result-linked payments before work begins. The financial forecast shows the expected value and its assumptions; it is not a revenue guarantee.

Paid as results are achieved. No upfront Selleris delivery fee. Each agreed result triggers a fixed payment within the total price, supported by completion evidence. You pay for the verified result, not hours spent or a date on the calendar.

Software costs stay separate. Required subscriptions, credits and cloud usage are disclosed separately and billed directly to you by providers, with zero Selleris markup. No upfront fee for our work does not mean no third-party costs.

Further work is your decision. Support, calibration and new capabilities are scoped separately. There is no automatic retainer, no obligation to buy the full roadmap and no repeat charge for an already delivered result.

Our commitment

We stand behind the result we agree.

Before work starts, we agree the result, completion criteria, verification method and the fixed payment it triggers. The scope also makes the required client and third-party inputs clear.

We do not invoice an undelivered result.

Where the relevant conditions remain unchanged, we complete the agreed correction cycle without an additional Selleris delivery fee. If the result is still not achieved, we close that result without its fee unless both parties agree in writing to a limited result and a reduced fee.

If scope or required inputs change, we agree how to proceed. Independently achieved results retain their payment status.

FAQs

Frequently asked questions.

Build & Improve: scope, cost, timing and responsibilities. What to expect before we start.

What is Selleris Revenue Loop?

Selleris Revenue Loop is a GTM engineering program that builds and continuously improves a client-owned revenue system on HubSpot across the full customer lifecycle: demand generation, prospecting, sales, onboarding, retention and expansion.

Selleris takes the initiative and delivers the agreed solution end to end: business and process design, data, AI agents, automation, reporting, implementation and enablement. The client does not need to design the solution or supply a technical task list.

How much does Selleris Revenue Loop cost?

Selleris agrees one fixed total price for your initial Build after the Free Revenue Diagnostic. You see the proposed results and their forecast financial value alongside the price, before committing.

For budget guidance, a focused quick-win project can start around $2,000 to $3,000; a more comprehensive implementation can reach $50,000 or more. These are budget guides in USD, not fixed packages or a price cap.

Build and Improve follow the same payment principles: no upfront Selleris delivery fee, with payment after agreed results are achieved and verified. Improve is commissioned separately, with no automatic retainer. Software, credits and cloud costs are disclosed separately and paid directly to providers, with zero Selleris markup.

Do we have to replace our CRM?

Not necessarily. HubSpot is the operational center of the revenue system, but your existing CRM, product, billing and support platforms can remain in place. The diagnostic establishes which information needs to move between them. Integration scope, limitations and costs are agreed for your actual setup.

When do we see results?

For both Build and Improve, timing depends on the result we agree to deliver. Your proposal defines the delivery schedule, dependencies and any observation period needed to verify completion. A working capability or completed asset may be verified before its wider business effect becomes visible.

What do you need from us?

Your growth objective, executive participation, relevant data and people who will operate the system. Confidential data is shared under NDA, with access proportionate to the work. For HubSpot, we use official partner access; if you do not have an account, we help you create a free one in your name.

You join the diagnostic kickoff and findings discussion. We lead the research and solution design, so you do not need to prepare a technical specification.

What’s the real total cost?

You receive one fixed Selleris price for the agreed initial Build, with software subscriptions, credits and cloud usage disclosed separately. The budget examples above illustrate different scopes; they are not a quote for your business.

The diagnostic presents the proposed results, their forecast financial value and the total price together. Subsequent Improve work, including support, calibration and new capabilities, is scoped and priced separately.

Can we test the approach before committing?

Yes. The free diagnostic includes a focused proof of concept, such as useful research, business-context work or a functional demonstration relevant to your situation. We explain what it proves and what remains untested.

The diagnostic takes 10 calendar days from readiness of the agreed minimum data and access. There is no Selleris fee for the diagnostic or included proof of concept, and no obligation to buy implementation.

How does payment work?

Build and Improve follow the same payment model. There is no upfront Selleris delivery fee. The agreement allocates fixed payments to independently verifiable results within the total solution price. Completion evidence accompanies the invoice when the corresponding result is achieved.

You have five business days to raise specific, supported discrepancies. The standard payment term is seven calendar days from invoice delivery, with the actual due date preserving the full review window under the agreed client business calendar.

Is paid advertising included?

Not by default. Any paid-advertising work must be explicitly included in the agreed scope. Advertising spend and relevant provider costs are separate from Selleris delivery fees and are disclosed before you commit.

How does Build & Improve work?

Build is the initial design, implementation and launch of your agreed revenue capabilities. Improve is the separately agreed support, calibration and development of that system as your needs and priorities evolve.

Your team runs day-to-day revenue operations and retains control of the accounts, data and delivered assets. We stay involved through value reviews and recommendations.

Improve follows the same principles as Build: agreed results, fixed prices and payment after achievement. There is no automatic retainer, and value reviews do not include unlimited technical support.

We’re in the EU. Does visitor identification work?

Company-level identification can be part of the agreed scope. We assess the provider, available data, traffic mix and applicable privacy requirements before choosing the approach.

This does not mean identifying every visitor or automatically enabling person-level identification. The proposal makes the relevant capabilities and limitations explicit.

Who actually does the work?

Selleris leads business and process design, engineering, implementation and team enablement. The delivery plan identifies the people responsible for the agreed work.

Your team retains day-to-day sales and customer-success responsibilities. Where product events are needed, we define and implement the receiving integration; your product team or existing contractor makes the required product-side changes.

Do we have to buy the whole roadmap?

No. You commission one meaningful initial Build around the priority worth addressing first. That stage may be focused or more comprehensive, depending on your situation.

The signed scope is a commitment, but the longer-term roadmap is not an automatic purchase obligation. Any later Improve work requires a separate agreement.

What if an agreed result is not achieved?

We do not invoice an undelivered result. Where the relevant conditions remain unchanged, we complete the agreed correction cycle without an additional Selleris delivery fee.

If the result is still not achieved, we close it without its fee unless both parties agree in writing to a limited result and a reduced fee. Changes to scope or required inputs are handled explicitly. Independently achieved results retain their payment status.

How long is your proposal valid?

Each tailored proposal from Selleris is valid for 30 calendar days from delivery, with its issue and expiry dates stated. When both parties sign, Selleris confirms and reserves the agreed team and start window without an advance payment.

After expiry, terms and availability are revalidated without an automatic price increase.

Do you guarantee revenue growth?

No. The proposal shows the expected measurable effect and its forecast financial value, with the assumptions behind it; the forecast is an estimate, not a guarantee.

What Selleris commits to is the agreed result: its completion criteria and verification method are fixed before work starts, and you pay only after that result is verified.

How is Selleris different from a HubSpot implementation partner or an outbound GTM agency?

A HubSpot implementation partner configures the platform and hands it over. An outbound GTM agency runs prospecting workflows, often on tools such as Clay, for the top of the funnel.

Selleris builds and improves the whole revenue system (demand generation, prospecting, sales, onboarding, retention and expansion) with HubSpot at the center, in accounts you own from day one. Each initial Build has one fixed total price, paid per verified result, with no upfront Selleris delivery fee and no automatic retainer, and the work is visible under the Glass Box standard.

Either of the other two models can be the right choice for a narrower need; the Free Revenue Diagnostic tells you which.

We're about to hire a GTM engineer. Should we still talk?

Yes, and the order matters. If the role does not exist yet, building the revenue system with Selleris first gives your future hire a working system, documented decisions and a clear boundary to take over, rather than a start from zero.

The Free Revenue Diagnostic shows what to build first and what the system would need from an in-house role; you then decide whether and when to hire. If the person is already on board, they join the diagnostic and run the delivered system with your team. Compare build vs hire.
