How we engage
Four ways New Castle 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

Staff augmentation
Plug senior engineers and designers into your existing team. Same stand-ups, your repo, your tooling — without the 6-month hiring cycle.

- 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.

- Data + SEO preservation
- Zero-downtime launches
