Your prototype works. Production is a different problem.

Greenfield Labs turns working prototypes into production microservices — the architecture investors expect and real users demand. Weeks, not months. Yours to own.

Talk to Us About Your Prototype

The demo worked. Now what?

Your prototype proves the idea. Investors are interested. Early users are asking for access. But the codebase that powered the demo will not survive real traffic, real data, and real security requirements.

You need microservices architecture. Typed contracts between services. Authorization on every endpoint. Test coverage that gives your investors confidence. Observability so you can actually debug production issues at 2 AM. Deployment infrastructure that scales.

You also need it in weeks, not quarters. You are burning runway. Every month spent rebuilding is a month not spent on growth, sales, and product.

Hiring a platform team to solve this takes months to assemble and costs more per year than most seed rounds can absorb. You do not have months. You have a prototype, a deadline, and the need to ship production-grade software yesterday.

That is exactly what we build.

You build the product. We build the production system.

What You Provide

Your existing codebase, prototype, or technical specification. A few hours of your time during discovery week to explain the domain and validate the architecture. That is it.

What We Build

A complete production system. Microservices architecture with typed contracts. CQRS and event sourcing for every domain. Two-layer authorization. 90%+ test coverage. Distributed tracing. Deployment-ready containers. Documentation your future engineering hires can read on day one.

The Partnership

How the partnership works.

Week 1

Discovery

Week 1

We map your domain, define service boundaries, and produce an architecture blueprint with typed contracts. You review it. You approve it. Nothing gets built until we agree on the plan.

  • Domain mapping
  • Service boundaries
  • Architecture blueprint
  • Typed contracts
Weeks 2-3

Build

Weeks 2-3

Production microservices are constructed against the approved blueprint. Every service passes quality gates: typed contracts, authorization, 90%+ coverage, tracing. You see progress daily.

  • Production microservices
  • Quality gate verification
  • Daily progress visibility
Weeks 3-4

Deliver

Weeks 3-4

Integration testing, performance validation, documentation. You receive production-ready services and everything needed to deploy. We walk through the entire system together so you understand every component.

  • Integration testing
  • Performance validation
  • Deployment configurations
  • System walkthrough
After Delivery

You Own Everything

After Delivery

You own everything. Source code, documentation, configurations. Your future engineering hires step into a clean, documented, tested codebase -- not a mess they have to reverse-engineer.

  • Complete source code
  • Full documentation
  • Deployment configs
  • Onboarding-ready codebase
Deliverables

Everything your investors will ask about. Handled.

Investor-Ready Architecture

Service boundaries, typed contracts, and domain models documented in detail. When due diligence asks "what does the architecture look like," you hand them a blueprint, not a whiteboard sketch.

Production Microservices

TypeScript with strict mode. CQRS and event sourcing. Zero infrastructure code in your business logic. Built to scale from ten users to ten thousand without rearchitecting.

Security From Day One

Two-layer authorization on every handler. Permission-based gateway access plus business-rule policy enforcement. Not bolted on later. Built in from the first line of code.

Comprehensive Test Suites

90%+ coverage enforced on every service. When your technical due diligence asks about testing, you show them the coverage reports, not a promise.

Full Observability

Distributed tracing, metrics, and dashboards. When something breaks at 2 AM (it will), you see exactly where, exactly why, and exactly what happened before and after.

Deployment-Ready Infrastructure

Containerized services, infrastructure configuration, deployment documentation. Ready for AWS, GCP, Azure, or your own servers. No vendor lock-in.

Onboarding-Ready Documentation

Architecture docs, service guides, and code that follows strict conventions. Your first engineering hire reads the docs, not the Slack history.

Built. Measured. Delivered.

Less than a single hire
A complete production system for a fraction of what you would spend on one senior platform engineer's annual compensation.
3 weeks from handoff to production
Not a rough estimate. Not a best-case scenario. A measured timeline from a real engagement with a real codebase.
13 microservices built by one developer in 15 weeks
The Greenfield platform makes this possible. Your production system is built on the same foundation that has been proven at scale.
469 tests. 90%+ coverage. Zero exceptions.
Every service. Every handler. Every edge case we can find. Coverage is a quality gate, not a metric we track and ignore.
FAQ

Questions founders ask.

Do you take equity?
No. We charge a fixed fee for a defined scope of work. You keep your cap table clean. We keep our incentives aligned with delivering quality work on time.
Who owns the code?
You do. Completely. Source code, architecture documentation, deployment configurations, test suites -- all of it. No retained licenses, no proprietary dependencies, no lock-in. It is your company's IP from the moment we deliver.
What if we do not have a codebase yet -- just a spec?
That works. We can build from a technical specification, wireframes, or a detailed product description. The discovery phase is designed to take whatever you have and turn it into an executable architecture blueprint.
Can we make changes after the blueprint is approved?
Yes, within reason. Minor scope adjustments during the build phase are normal and expected. Significant changes are scoped as additional work with clear timelines and costs. The blueprint review exists to minimize this -- we get it right upfront.
What happens when we hire our own engineers?
They inherit a clean codebase with strict conventions, comprehensive documentation, and 90%+ test coverage. We have seen engineers onboard to our delivered systems in days, not weeks. The architecture is designed to be readable and extensible by any competent TypeScript developer.
Do you provide ongoing support?
We offer post-delivery support packages for the transition period. But the goal is full independence. We build systems that your team can maintain and extend without us. If you need additional services built later, we are happy to do another engagement.
How does this compare to hiring a technical co-founder?
A technical co-founder costs equity, takes months to find, and may or may not build production-quality systems. We cost a fixed fee, start immediately, and deliver a system with enforced quality standards. We are not a co-founder replacement -- we are a production infrastructure solution that buys you time to find the right long-term technical leader.

Ship production. Not another prototype.

Tell us what you have built. We will tell you what production looks like — scope, timeline, and cost. No commitment. Just a straightforward technical conversation.
