Starter project
Can start at around $2,000 to $3,000
For one useful result, such as company-level visitor identification, segments, a fit score or a sync between your current CRM and HubSpot. Each starter result is useful on its own.
For B2B SaaS founders, CEOs and sales leaders
You pay for verified results, then a monthly fee only if you choose it.
Everything is built in your HubSpot and your accounts, and it is yours from day one.
Sergey Danishevskiy, CEO. Every diagnostic starts with a call with me, and you see one fixed price before you commit.

Depending on the scope we agree.
Improve, a retainer
A fixed monthly fee agreed with you
A named Selleris engineer responsible for your system, upkeep of the agreed workflows, integrations, agents and data, adaptation to tool changes, calibration of scores and routing, and extension within the reserved capacity, with a monthly record of what was done.
What drives the price
- How many results
- How many tools and data sources to connect
- The state of your data
- Whether a CRM migration is part of it
Indicative Selleris service fees in USD, not a quote for your business. The diagnostic determines the initial scope and one fixed price.
What is included, and when it is too early
If it is too early, Sergey will tell you on the call.
Included
- Design, build and launch of the agreed results in your accounts
- Documentation
- Handover to your team
Not included
- Software licenses and usage, which are in your name and paid to the vendor, with no Selleris markup
- Selling for you or finding leads
- Work beyond the agreed results; Improve, if you choose it, covers upkeep and extension within its reserved capacity
Too early if
- You are still finding out who buys
- Nobody sells and there is no self-serve sign-up to convert
How a result is verified
Before work starts, every result gets its completion criteria, the evidence that proves it and the payment it triggers. The evidence comes with the invoice. You have five business days to raise a specific, supported discrepancy. We do not invoice a result that is not delivered.
What a Build and Improve replace
A Build, and Improve if you choose it, replace two things: an outside SDR agency that books meetings from its own tools, and hiring a GTM engineer to set up and run the tools you already pay for. The build-vs-hire calculator compares a Build and Improve with a GTM engineer hire for your own case.

FAQs
Questions about price and payment
How much does Selleris Revenue Loop cost?
Selleris agrees one fixed total price for your initial Build after the free diagnostic. You see the proposed results and their forecast financial value alongside the price, before committing. For budget guidance, a starter project can start around $2,000 to $3,000; a full Build can reach $50,000 or more. These are budget guides in USD, not fixed packages or a price cap. Build has no upfront Selleris delivery fee: you pay after agreed results are achieved and verified. After Build, you can choose Improve: Selleris stays on as your GTM engineering capacity, instead of a hire, for a fixed monthly retainer agreed in advance. Nothing continues automatically. Software, credits and cloud costs are disclosed separately and paid directly to providers, with zero Selleris markup.
How does payment work?
Build and Improve are paid differently. Build has no upfront Selleris delivery fee: the agreement allocates fixed payments to independently verifiable results within the total solution price, and 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. Improve, if you choose it after Build, is a fixed monthly retainer for reserved Selleris capacity, invoiced at the start of each month, with the scope, fee, term and how either party ends it set in its agreement before the first month.
How does Build & Improve work?
Build is the initial design, implementation and launch of your agreed results. It is a one-time phase with agreed results, fixed prices and payment after each result is verified. Improve is the ongoing support, calibration and development of that system as your needs and priorities evolve: Selleris stays on as your outside GTM engineering capacity, instead of you hiring one, for a fixed monthly retainer. You choose Improve after Build; it never starts automatically. 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 whether or not you choose Improve, and value reviews do not include unlimited technical support.
