[GTM Engineering on HubSpot]

A revenue system you own.

Selleris engineers revenue systems for B2B SaaS and tech-enabled companies: pipeline built on signals, data, and AI agents inside your HubSpot, not on habit and headcount. Custom agents run in your own Azure tenant. Not a marketing agency. Not an AI-SDR vendor. Engineers who build the machine, then hand you the keys.

[Who this is for]

You have a growth target. You don't have a revenue system.

You plan to grow thirty, maybe forty percent this year.

Now look at how revenue actually works in your company. Deals depend on specific people and what they remember. Sales and marketing don't share data. Reports live in spreadsheets. Outbound was launched three times and stopped three times.

There is no system. That's what we build: a revenue system inside your HubSpot that runs on data, signals, and AI agents, with reporting your board can trust. You own all of it. Call it RevOps, call it GTM engineering, or don't call it anything yet. The system runs either way.

[The Achitecture]

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, Grok and Perplexity.

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.
