[AI Agents]

AI agent development,
in your own tenant.

Selleris builds AI agents for B2B SaaS and tech-enabled SMBs, from prospecting and deal follow-up to customer success and internal operations. We configure HubSpot's native agents where they fit and build custom agents in your Azure tenant where needed.

We start with the process worth improving, then connect agents to your data and tools with agreed permissions and approval points. You control the accounts and delivered assets, with documentation your team can use.

[The Tenant]

What custom AI agent development means, done right

Custom AI agent development means building agents around your workflows, data and tools. Selleris develops custom agents in your Azure tenant, with access, logging and data residency requirements agreed as part of the scope.
Where HubSpot's native capabilities fit, we configure Breeze in your portal. Your custom code, configurations and documentation stay in accounts you control, so your team or another implementation partner can maintain and extend the solution.
Your custom code. Your accounts. Your choice of implementation partner.
The approach behind it is in the GTM engineering manifesto.
[What We Build]

Agents for revenue, and beyond.

Outreach agents

Signal-triggered sequences drafted, personalized, and routed by agents under your brand; your team closes.

Deal agents

Follow-ups, meeting prep and next steps drafted in HubSpot using native or custom agents. Your team handles sales conversations.

Customer success and upsell agents

Onboarding, customer health signals, churn alerts and renewal or upsell plays, with agreed handoffs to your team.

Business process agents

Quotes, invoicing, reporting and internal copilots on Azure AI Foundry, built around your processes and agreed permissions.

Orchestration and integrations

Agents connected to your CRM, ERP and data layer, with clear rules for sharing data and coordinating actions.

Guardrails and evaluation

Approval gates, eval suites, logging, and cost control, so agents ship with brakes, not just gas.

Two runtimes, one team

We configure Breeze in your HubSpot portal and build custom agents in your Azure tenant. When a workflow needs both, we connect them to work with your data and agreed permissions.

After launch: We can manage your custom agents' Azure runtime under a separately agreed Azure Management plan. Development and Azure consumption remain separate costs, with usage billed by Microsoft directly to you.

[The Practice]

AI agent development, with clear scope and pricing.

Start with a free diagnostic and a focused proof of concept. Standalone AI agent development is scoped as a fixed-price project, with agents, integrations, guardrails, documentation and commercial terms agreed before work starts.

Selleris Revenue Loop follows our Build & Improve model. We agree measurable results and one fixed total price for the initial implementation. You pay after those results are achieved and verified, with no upfront Selleris delivery fees. Further improvements are agreed separately, with no automatic monthly retainer.

As a HubSpot and Microsoft Solutions Partner, we keep the work and documentation visible through Glass Box, in accounts you control. Azure runtime management is agreed separately. Software, credits and cloud costs are disclosed separately and paid directly to providers with zero Selleris markup.
[The Questions]
