[Who this is for]

You have a growth target.
Your revenue system needs to keep up.

You have customers and a clear ambition for what comes next. Whether sales are founder-led or run by an established team, you need a stronger revenue system without having to design and build it yourself.

The gaps may show up as missed buying signals, stalled deals, slow onboarding or overlooked renewal and expansion opportunities. Leaving them unresolved means continuing to lose opportunities, time and money.

Selleris Revenue Loop starts with the constraint worth addressing first. Build creates the agreed capabilities in your environment. Improve develops the system as your priorities evolve, with further work agreed separately. We lead the design and implementation. Your team runs day-to-day revenue operations.
[The Architecture]

Ownership isn't a feature. It's the architecture.

Most agencies monetize dependency. We sell the opposite: a system that survives us. That is the point.

Your data.

Lives in your HubSpot. Records, pipelines, and reports, built in your portal, never ours. Fire us tomorrow and lose nothing.

Your playbooks.

Documented in your workspace. Every sequence, score, and decision rule, written where your team can read it, not locked in our heads.

Your agents.

Run in your Azure tenant. Custom AI agents deployed on Azure AI Foundry under your SSO, your audit logs, your data residency.

What we engineer.

Foundation
Data
Enrichment, segmentation, and scoring

Every account enriched, segmented, and scored inside your HubSpot. Your team works the right 150 accounts, not the loudest 5,000.

Demand
AEO
Answer Engine Optimization

Your company becomes the answer AI assistants give. Definitions, comparisons, and proof engineered to be cited by ChatGPT, Claude, Gemini, Perplexity, and Grok.

Identification
Signals
Buying intent and visitor identification

Anonymous traffic turned into named accounts. Intent signals show who is in-market before anyone fills a form.

Activation
AI agents
Signal-based outreach, run by agents

Sequences triggered by real behavior, not by cold lists. AI agents draft, personalize, and route; your team closes.

Sales
AI agents
Deal agents inside your CRM

Follow-ups, meeting prep, and next steps drafted by agents in HubSpot, native or custom. Deals stop dying of forgetfulness.

Success
AI agents
Customer success agents

Onboarding, health signals, and churn alerts run by agents. Support conversations become revenue signals.

Expansion
AI agents
Upsell and renewal agents

Usage triggers spotted and worked automatically: renewal plays, expansion signals, warm handoffs to humans.

RevOps
Reporting
Revenue reporting that tells the truth

MRR, churn, and pipeline in one place inside your HubSpot. The reporting spine your board can trust.

All of it inside your HubSpot and your Azure tenant, registered in your name from day one.

Ten days. No charge.

You tell us the number your plan depends on; we turn it into the chain that has to produce it: target growth, new ARR needed, qualified pipeline required, and the exact floor we would put in a contract.
