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.
Free diagnostic with a focused proof of concept. No obligation to buy implementation.
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.
Your environment
Access, logging and data residency requirements agreed for your solution.
- Breeze agents configured in your portal
- Custom agents built on Azure AI Foundry
- Azure Management plans from $249/year, plus cloud usage

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
AI agents, answered straight.
The questions teams ask before they commission custom agents. If yours is missing, bring it to the diagnostic call.
What is an AI agent?
Software that pursues a goal by taking actions, not just answering prompts: it reads context, decides the next step, uses tools, and executes, with a human approving where it matters. In revenue work that means agents that enrich accounts, draft outreach, prep deals, and watch churn signals inside your CRM.
How do you build a custom AI agent?
We first map your workflow, data and required actions. The free diagnostic includes a focused proof of concept and a recommendation for next steps. It takes 10 calendar days once the agreed minimum data and access are ready.
Implementation covers the custom agent in your Azure tenant, required integrations, permissions, approval points and testing against agreed criteria. We document the solution and hand it over to your team.
Whose cloud do the agents run in?
Custom agents run in your Azure tenant. We configure native Breeze agents in your HubSpot portal. Access, logging and data residency requirements are agreed for the solution.
Your custom code, configurations and documentation stay in accounts you control. Azure consumption is billed by Microsoft directly to you.
Breeze agents or custom agents: which do we need?
We use Breeze where its native capabilities fit the workflow. Custom agents are scoped when you need additional logic, integrations or processes beyond those capabilities.
You do not need both by default. The choice follows your requirements, existing tools and agreed scope.
Are AI agents just chatbots?
A chat window is one possible interface. The agents we implement can monitor signals, prepare work and take permitted actions in connected systems, with human approval where required.
What does AI agent development cost with Selleris?
Standalone AI agent development is a fixed-price project, scoped after the free diagnostic. The deliverables and commercial terms are agreed before work starts.
Build: Within Selleris Revenue Loop, the initial implementation has agreed measurable results and one fixed total price. You pay after those results are achieved and verified, with no upfront Selleris delivery fees.
Improve: Further support, calibration and development of the Revenue Loop system are agreed separately, with no automatic monthly retainer.
Azure runtime management is a separate service, with Azure Management plans from $249/year, plus cloud usage. Software, credits and cloud costs are disclosed separately and paid directly to providers with zero Selleris markup.
The Diagnostic
Bring your growth ambition. Leave with a clear next step.
We use your business context and agreed data to identify the priority constraint, develop a focused proof of concept and recommend your next steps.
10 calendar days from readiness of the agreed minimum data and access. No Selleris fee for the diagnostic or included proof of concept. No obligation to buy implementation.
