Services

Senior product judgment, hands on the code.

We work as your product design, engineering and fractional product & tech team. Senior people who can define the product, design it and ship it, without the handoffs.

01

MVP to Production

Fixed scope, quoted after a review

Your AI-built MVP, made ready for real customers.

You built a working product fast with Cursor, Lovable, Bolt, v0 or Replit. Now it needs to survive real users, real data and real money. We audit the code, fix what will break, and harden it: architecture, auth and data rules, payments, performance, tests, CI/CD and observability. You keep the momentum and lose the risk.

  • Code, security and architecture review
  • Auth, data-access rules and secrets fixed
  • Performance, accessibility and SEO pass
  • Tests, CI/CD and staging environment
  • Monitoring, error tracking and backups
  • Launch checklist and handover docs

02

Product Diagnostic

Starting at $2,500

Find the right problem before building the wrong solution.

A focused engagement for a product that feels unclear, stalled or unnecessarily complicated. We review the product, users, competitive context, UX and technical constraints, then identify the highest-leverage opportunities.

  • Product and UX audit
  • Key problems and opportunities
  • Prioritized recommendations
  • Product direction
  • Actionable next-step roadmap

03

Product Sprint

From $15,000

Turn an idea or product problem into something real.

A concentrated strategy, design and prototyping engagement built around one important product challenge. Depending on the project, the sprint moves from product definition through UX, interface design, technical architecture and a functional prototype.

  • Product definition
  • User flows and UX
  • Interface and system design
  • Interactive or functional prototype
  • Technical direction
  • Validation and next-step plan

04

Fractional Product & Tech Lead

From $4,000/month

Senior product and technical leadership, without another full-time executive.

Ongoing product strategy, design and technical leadership for companies that need an experienced builder embedded in the team. Useful for founders turning priorities into execution, teams between product leaders, or technically ambitious products that need design and engineering to move together.

  • Product strategy and prioritization
  • UX and product design direction
  • Technical and architecture decisions
  • Prototype and feature development
  • Team and vendor direction
  • Founder and product-team support

Who we work with

Good fit if…

  • You shipped an MVP with AI tools and now need it to be secure, fast and maintainable.
  • The product idea is promising but still ambiguous.
  • An existing product has become difficult to use or evolve.
  • The interface needs to make complex data understandable.
  • AI needs to become a useful product experience rather than a feature checkbox.
  • Software needs to talk to sensors, devices or hardware.
  • You need senior product leadership and hands-on execution in the same person.

Questions

FAQ

Can you take over an app built with Cursor, Lovable, Bolt or v0?

Yes. That is the core of our MVP to Production work. We start with a review of the codebase, data model, auth and hosting, tell you plainly what is solid and what is risky, then fix and harden it in priority order. Rewrites are a last resort, not the default.

Do you only do design?

No. We work across product strategy, UX, interface design, prototyping and production engineering. The scope depends on what moves the product forward.

Do you work with existing products?

Yes. A Product Diagnostic is often the right starting point for an existing product that has accumulated UX, product or technical complexity.

Can you build the product after designing it?

Yes, when the technology and scope fit. We use functional prototypes and production engineering when they give more useful evidence than static design alone.

How do you use AI in your own work?

Every day. AI-assisted engineering lets a senior studio move at the speed of a much larger team. The difference is senior judgment: architecture, security, data integrity and UX decisions are ours, reviewed and tested, not accepted blindly from a model.

Do you work with hardware and sports technology?

Yes. We build the product and software layer around sensors and connected hardware, from BLE pairing and firmware direction to telemetry dashboards, video sync and coaching tools.
