Wrenq

Services

Senior engineering for the parts of your product that matter.

We work with founders and product teams that want a small, senior partner — not a body shop. Engagements typically run from a focused 4-week sprint to a long-running embedded relationship.

Where we're strongest

Three domains we keep coming back to.

Healthcare software

We build patient-facing apps, clinical dashboards, and integrations with EHR and lab systems. Privacy, auditability, and uptime are first-class concerns — baked into the architecture, not bolted on before launch.

AI agents

We design and ship LLM-powered agents that do real work: voice receptionists (like owlcall.com), chat copilots, and autonomous workflows that call your APIs, route tickets, or close the loop with humans. Tool-calling, evaluations, guardrails and observability are part of the build, not a slide.

Property management software

From single-landlord SaaS to multi-property operations, we build the rent flows, maintenance ticketing, accounting integrations, and tenant communication that property managers actually use day-to-day.
