[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.

Your accounts, data and delivered assets stay under your control. Build & Improve helps the system evolve without making you dependent on Selleris to keep using it.

Your data.

Your revenue data stays in systems you control, with HubSpot at the center. We connect the platforms needed for the agreed scope. Your access does not depend on ongoing Selleris services.

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.

Native agents run in your HubSpot account. Where custom capabilities are needed, we deploy them in your Azure tenant. Agents prepare work first; autonomous actions require explicit permission, with exceptions handed to your team.

What we engineer.

Foundation
Data
Business context, data and scoring

Your market, buyers and use cases mapped to the agreed lead and customer base. Enrichment, segmentation and explainable scoring help your team prioritize prospects and understand existing accounts.

Demand
AEO
Answer Engine Optimization

Research and content built around the questions your buyers ask. Definitions, comparisons and evidence make your expertise easier to evaluate, with AI visibility tracked separately from leads and revenue.

Identification
Signals
Buying signals and visitor identification

Identify visiting companies where data is available and connect website activity with relevant account signals in HubSpot. Assess fit, context and timing before deciding the next action.

Prospecting
AI agents
Account research and signal-based outreach

Agents research accounts, prepare personalized outreach and route replies with context. Sending is enabled only within agreed permissions, with exceptions passed to your team.

Sales
AI agents
Deal preparation and follow-up

Agents prepare discovery, meeting briefs and follow-ups using SPICED by Winning by Design. Customer needs, decision criteria and next steps stay connected as the deal progresses.

Success
AI agents
Onboarding and customer health

Carry sales commitments into onboarding with clear owners and milestones. Connect adoption, support history and value evidence to surface delays and retention risks for your team to review.

Expansion
AI agents
Renewal and expansion opportunities

Bring together usage signals, changing customer needs and renewal dates. Agents prepare account reviews and next actions, with commercial decisions and exceptions routed to your team.

RevOps
Reporting
Revenue reporting you can act on

Connect pipeline, revenue, onboarding, retention and expansion in reports your team can use. Keep activity, observed effects and forecasts distinct, and use the findings to prioritize Improve work.

One connected system, delivered through Build & Improve. The diagnostic defines your initial scope; further work is agreed separately. Built around HubSpot, in accounts you control.
