Build Demo
Working prototype + multiple flows + persistence + feature prioritization + product brief. $1,799. About 10 days. $1,799.
No calls. No contracts. Delivered in ~10 days.
The real problem
The product idea is solid. Maybe you've sketched the flows. Maybe you've built a Figma prototype. Maybe you've even started coding — and realized the timeline is 6 months, not 6 weeks.
Something people can actually click through, interact with, and react to. Not wireframes — a working prototype with real logic. What you need isn't an MVP. It's proof that the concept works.
Dev agencies want $50K-$100K and 3-6 months. You have a demo day in 3 weeks.
Speed to demo is speed to feedback, funding, and market.
The cost of waiting
Every week without a working demo is a week of pitch meetings with slides instead of substance.
Investors fund what they can experience, not what they can imagine.
Building a $50K MVP before validating is the most expensive mistake in startups.
A $1,799 prototype proves the concept before the real investment begins.
Your competitor is building. Right now.
Speed to demo is speed to feedback, funding, and market.
The options you've already considered
The full build — before knowing if the concept works. The most expensive way to find out the idea needs changes.
Fast but limited. Real logic, persistence, and custom flows hit the platform ceiling quickly.
2-4 months. No product thinking. Builds exactly what you describe — even if what you describe needs refinement.
If you have 3-6 months of engineering time available, go for it. Most founders don't.
A different model
Working prototype, not a mockup.
Multiple user flows with real logic and persistence. People can use it — not just look at it.
Product thinking built in.
The Product Concept Brief and Feature Prioritization ensure the right things are built. Not just code — product strategy.
2 client checkpoints.
After directions and after core build. Feedback is incorporated before moving forward. No surprises at delivery.
Handoff-ready.
Product Brief + source code + setup instructions. Any developer can pick up where this leaves off.
No calls. No contracts. Full ownership.
The starting point
The Brief Chat is a guided conversation — not a form, not a phone call — that captures the business, customers, goals, and what makes it different. About 20 minutes.
Most people struggle to explain their business clearly. The Brief Chat draws it out — the right questions, in the right order, with room to ramble. The ramble becomes the strategy.
20 minutes → ~10 days later, professional deliverables land in the inbox.
What the Brief Chat covers
What your product does and who it's for
The key user flows that need to work
What data needs to persist between sessions
What you've built or designed so far
Demo day, pitch, or testing deadline if any
Anything else that would help — in your own words
What's included
Every deliverable is built from the Brief Chat — tailored to your product and goals.
Problem, target user, solution, assumptions, success criteria.
Multiple user flows, real logic, persistence. Not screens — an app people can actually use for a guided walkthrough.
Supabase, Turso, or other persistence as needed. Data persists between sessions.
Impact vs effort analysis informed by real build insights. Build now / build later / don't build.
Decisions made, trade-offs, rationale, next steps. A handoff document for the next developer or investor.
What works, what to test, what v2 should address.
Full React/Vite codebase. GitHub repo. Setup docs for any developer.
Agencies and consultants charge $33,000 – $90,500 for these deliverables.
Ironbrev delivers all of this for $1799 — because the model is different, not the quality.
No calls. No contracts. Delivered in ~10 days.
The math
If the prototype helps close a funding round, the ROI is astronomical. If it reveals the product needs pivoting before a $50K build, it just saved the business. Either way: $1,799 is the cheapest validation available.
At $1,799, the downside is $1,799. The upside is a funded company.

P.S. A dev agency will spend 3 months building something you're not sure works. For $1,799 and about 10 days, you'll know — and have the code to prove it.
