Bespoke software, battle-tested modules.

Insurance software, assembled - not invented each time.

We build custom platforms for carriers, MGAs and brokers on a library of production-hardened modules - rating, quoting, portals, carrier integrations - so you ship in quarters, not fiscal years.

§ 05 · ENGAGEMENT MODEL

Four phases. Same team start to finish.

No discovery-to-build handoffs. The architects who scoped your project ship it.

01SCOPE

Two-week scoping sprint

We embed with your underwriting, ops and IT teams. We come back with a module map, a build plan, a risk register, and a fixed quote.

OUTPUTS· Module map· Build plan· Risk register

02ASSEMBLE

Compose from the library

We stand up the platform from pre-built modules in your environment. Auth, hierarchy, rating, carriers, portals - wired together in weeks.

OUTPUTS· Tenanted env.· CI/CD· Module wiring

03EXTEND

Build what is uniquely yours

Custom rating, niche workflows, integrations specific to your book. We extend the library; you keep the source.

OUTPUTS· Custom rating· Niche flows· Source handoff

04OPERATE

Ongoing practice

A small embedded team after launch. Carrier integrations evolve. Modules upgrade. You stay close to the work, not the rebuild.

OUTPUTS· SLOs· Roadmap· Carrier additions

§ 06 · OFF-THE-SHELF

Don't need it bespoke? Meet Envoy.

Envoy is the same module library Growthmill assembles for bespoke engagements - pre-configured, multi-tenant, and ready to deploy. If your roadmap fits the standard shape, Envoy ships in days instead of quarters. If it doesn't, that's where the Growthmill practice picks up.

Visit envoy.insure Or explore the module library →

PRE-ASSEMBLED

All 19 modules wired up

Auth, rating, carriers, proposals, portals and payments - configured for the most common workflows.

TIME TO LIVE

Days, not quarters

PRICING

Subscription, per-seat

Predictable opex. Upgrade to a bespoke build whenever your roadmap diverges.

§ 07 · THE PRACTICE

Built by people who have shipped insurtech before, at insurers you know.

Growthmill is an insurance software practice, not a generalist agency. Our architects came up at carriers, MGAs, and agencies. The module library is what we keep wishing we had on the last engagement, brought to the next one.
