Three ways to work with us

Pick the one that matches where your product is today. All three start the same way.

You have an idea, a prototype or a spec, and need one team to build the whole product.

New Product Development

Take a new SaaS, marketplace, operational or mobile product from requirements and architecture to production.

Product architecture, UX/UI, Frontend, Backend & APIs, Mobile, Auth, billing & permissions, Infrastructure & deployment.

More about New Product Development

Your product has users, and it needs major features, a mobile app or a sturdier backend.

Existing Product Engineering

Extend, modernize or scale software that already has users.

Major features, Mobile apps for existing web products, Backend architecture & performance, Integrations & AI features, Technical modernization.

More about Existing Product Engineering

You need ongoing engineering and someone to own the codebase, without hiring a team.

Dedicated Product Team

An engineering team embedded in your product, month to month.

Ongoing feature delivery, Architecture & technical leadership, Maintenance & monitoring, Roadmap planning with your team.

How an engagement starts

You know the architecture, the milestones and the price of the build before you commit to it.

  1. Free Idea Teardown

    Not sure your idea is worth building yet? Answer the questions we ask before we build anything, and get a straight verdict: build it, rethink it, or wait.

    Start the teardown
  2. Intro call

    A conversation with the engineers who would build it, about your users, your constraints and what done looks like.

  3. Technical scope

    Fixed price. A written document with the architecture, data model, feature breakdown, a milestone plan with dates, assumptions and what is not included. For existing products it starts with a codebase and infrastructure assessment.

    Yours to keep, and credited to the build if you continue with us.

  4. Build

    Fixed-scope milestones, a demo every week, and repositories and infrastructure you own from day one.
