What we build into production.
Orchestration, evals, guardrails, integrations, and operations — with proof tied to shipped work.
Agent orchestration
Supervisor patterns, tool-calling loops, failure recovery, and knowing when a pipeline beats an agent.
MCP & tool integration
Connectors for workspace, CRM, email, and webhooks with isolated token stores and explicit scopes.
Eval & verification
Regression tests, smoke gates, and structured checks before production deploy — not vibe-based QA.
Guardrails & agency limits
Preview-confirm flows, connector honesty, least-privilege tools, and kill-safe outbound actions.
Production observability
Health endpoints, log scans, runtime verifiers, and operator-visible job states.
Cost-aware model routing
Route by task complexity, cache where it matters, and design loops with inference economics in mind.
Our Philosophy: Built Different
Every system we release goes through pressure testing, refinement, and real-world validation.
Clarity over Complexity
Only ship what makes things clearer.
Speed over Sprawl
Momentum matters. Fast beats perfect.
The Counterpart Model
We don't build tools. We build active agents.
