How we engage
Four ways Old Greenwich teams work with Envert.
Pick the model that matches where your software is today — validation, growth, scale, or rescue. Every engagement is led by a senior product team, not account managers.
MVP sprint
Take a validated idea from a Figma file to a shippable product. One designer, two engineers, weekly demos. End state: real users on a real stack.
- Discovery + design system
- Full-stack build
- Auth, payments, analytics
- Launch on day 42
Growth build
You have early traction and need to ship faster than your team can hire. We embed a senior squad to compound features, polish UX, and harden infrastructure.

- Design + engineering pod
- Performance & SEO
- Feature flag rollouts
Staff augmentation
Plug senior engineers and designers into your existing team. Same stand-ups, your repo, your tooling — without the 6-month hiring cycle.
- React / TypeScript / Node
- React Native / Expo
- Postgres / Supabase
- AWS / Cloudflare / Vercel
Modernization
Replatform a legacy app, migrate off WordPress / Wix / Webflow, or rewrite a brittle monolith. We ship in slices so revenue keeps flowing during the move.
- Stack audit & migration plan
- Incremental cut-over
- Data + SEO preservation
- Zero-downtime launches
