PoC, Prototype & MVP

Prove it before you fund it

A working proof of concept, a prototype users can click through, or an MVP real customers can touch, built fast enough to test the idea before you commit the full budget to it.

Why start small

What proving it first gets you

Test new ideas, fast

We turn a hunch into a working proof in weeks, so you learn what's real before committing a full build budget.

01 / 04

De-risk the big decision

Prove the hardest technical assumption first, so the expensive part only happens once the evidence supports it.

02 / 04

Win stakeholder buy-in

A working demo changes the room. It's far easier to fund something a board can see running than a pitch deck.

03 / 04

Move to build with clarity

A PoC becomes the blueprint: scope, architecture, and risks understood before the real build begins.

The process

From idea to proof, step by step

[01]

Discovery workshop

We align on the goal, the users, and the single riskiest assumption worth proving first.

[02]

Architecture & build plan

A lean architecture aimed squarely at the proof, nothing built that the question doesn't need.

[03]

Build the proof

We build the smallest working thing that answers it, running, so you can see it with your own eyes.

[04]

Review & refine

We measure against the success metrics and refine, a straight read on whether it works.

[05]

Roadmap to build

If it's a go, we fold the proof into a costed, sequenced plan to take it to a production-grade product.

Where are you starting from

Not sure yet, or ready to prove it?

Every PoC and MVP starts from one of two places. Tell us which one, and we'll scope from there.

Not Sure Yet
“There's an idea on the table, but nobody's tested if it actually works.”

A concept with real potential but an unanswered technical or market question sitting underneath it. We scope a fast, focused proof that answers that question before anyone commits real budget.
Book a discovery session Get a scoped proof, not a guess
Ready to Prove It
“We know what we want to test. We just need it built.”

The assumption is defined and the target users are identified, you're just missing the hands to build the proof or MVP itself. We plug in and start shipping within days.

Deliverables

What you walk away with

Source code

The complete, documented source for the proof or MVP, yours to keep, extend, or take further.

Runnable package

A working build your people can install and demo without us in the room.

Findings report

A clear write-up of what was tested, what the results were, and what they mean for the next decision.

Next-step recommendations

Prioritized suggestions for where to take the idea next, and what to watch for.

Technical documentation

Architecture, decisions, and runbooks, so anyone can pick it up and run with it.

App types

Built for whatever you're proving

01

iOS · Android
Mobile applications
Prove a mobile concept on real devices before committing to a full native or cross-platform build.
- On real handsets, not a simulator
- Installable build your people can demo
- Native or cross-platform, decided on evidence
02

Web apps & platforms
Web applications
Validate a complex web workflow or platform idea with a working, clickable proof.
- The whole flow, start to finish
- Running on a URL you can share
- Your own data, not placeholder text
03

Models & data
AI & data products
Test whether the models, data, and accuracy can actually deliver the outcome you need.
- Run against your messiest cases
- Accuracy measured, not asserted
- A pass mark agreed before we build
04

Systems talking
Integrations & APIs
Prove that the systems can talk to each other the way your idea depends on.
- A live call between both systems
- Rate limits and failure modes mapped
- Sandbox credentials, never your production keys
05

Workflow proof
Automation systems
Show that a workflow can be automated reliably before you scale it across the business.
- One full run, end to end
- Exceptions logged, never quietly dropped
- Time saved counted on your own volumes

Why Growth Nerve?

People who've actually shipped proofs before

Senior practitioners, not a rotating bench of junior hires. 15+ years building production software, now focused on fast proofs and lean MVPs.

Candid conversations, clear vision

Straight talk, no jargon. We tell you what's worth proving and what isn't, even when it's not what you hoped.

We've seen where proofs go wrong

Built PoCs and MVPs across EdTech, e-commerce, healthcare, and professional services, so we design out the traps before they cost a rebuild.

You own everything

Code, accounts, and docs handed fully to you, with training to run it. No lock-in, ever.

Senior team, fixed price

Senior practitioners who've owned production systems, on a fixed price for fixed scope, never hourly.

Case studies

Work we’ve built and handed over

Every figure below is real and shared with the customer's permission. Three of the five asked not to be named, so we describe them by niche instead.

Bring the build you’re weighing up

Thirty minutes on the system you’re considering, not a demo. You’ll leave with the shape of the build, the two or three things most likely to make it go wrong, and a rough cost band — yours to keep whether you hire us or not. If it’s a build we’d talk you out of, you’ll hear that on the call.
