Launch Your MVP in 30 Days. Fixed Price.
Skip the hiring spiral. Ship the MVP your investors are waiting to see.
We are the senior team seed-stage founders call when their idea has to be live, polished, and ready to pitch — before the next board meeting.
- One fixed quote
- One dedicated team
- Shipped in exactly 30 days
Built by a team led by a principal engineer with 10 years shipping for Bay Area startups.
You don't need a developer. You need a team that ships.
Most startup MVP developers quote a 6-month timeline and 40 pages of discovery documents. We refuse to work that way. If you have a validated idea and a clear user, you will be in TestFlight in 4 weeks.
The discovery trap
Agencies demand 8 weeks of paid workshops before a single line of code is written.
We hold a scoping call on day 1. You get a sprint-ready spec on day 3. You see your first build demo on day 10.
The hourly billing trap
Agencies push for hourly billing because it is flexible for them and expensive for you.
We do fixed price app development. You get a firm quote upfront. If scope grows, we tell you the cost — we never send surprise invoices.
The bait-and-switch trap
You talk to a senior architect today, get a junior tomorrow, and get ghosted the week after.
You get one dedicated delivery team. The same engineers stay with you from kickoff to launch, and our CEO is on every kickoff call.
Everything an investor needs to see. Nothing they won't.
We take full ownership of delivery — you get a finished product, not a contractor to manage.

Day 1 to launched. Your exact timeline.
We quote a 30-day MVP because that is what 80% of our builds actually take. If your scope is complex and needs 45–60 days, we tell you on day 1 — not day 25.
You approve the plan before we start.
First clickable demo on day 10.
Weekly progress demos on video.
We handle reviews and resubmissions.
Your warranty support kicks in.
Stop paying for agencies to learn on your dime.
Principal Engineer — 10 years shipping for Bay Area startups
Staff augmentation gives you bodies — you still manage them, onboard them, and hope they ramp up fast. We operate differently.
Your project is led by a principal engineer with a decade of experience shipping production software. Every kickoff starts with him on the call. Our engineers are trained for 6 months before they touch client work. No one on your team is learning React on your budget.

From MVP to acquisition: we were LivLyt's engineering team from day one.
LivLyt came to us in 2021 with an idea and no code. We built the MVP. They raised seed capital inside 3 months, got into 500 Startups, and pivoted from a B2C marketplace into a B2B IT-management SaaS — with Propelius shipping every line of code through every pivot. They onboarded some of the largest companies in the Middle East and, in 2024, were acquired by ZenAdmin.

- 2021Seed round closed in 3 months
- 2022Accepted into 500 Startups
- 2024Acquired by ZenAdmin
“Propelius is the only vendor we'd use again without a second quote.”

This is an example package. Your actual scope and estimate may vary based on your specific requirements. We lock in a final fixed quote after the free scoping call — and we never invoice a surprise.
We back every project with our Triple Guarantee:
We deliver on the quoted timeline or every day late is free (pro-rated from your final milestone payment). If something on our side pushes the date, we pay for it.
Your quote is your price. If scope changes, we quote the exact delta in writing, and you approve it before a line of code is written.
If we realize on the free scoping call that your idea isn't a 30-day fit, we tell you immediately, refer you to a better match, and send you a $250 Amazon gift card for your time.
- If we ship — you get an investor-ready MVP for $10,000.
- If we miss the date — the cost overrun is on us.
- If we are not a fit — you walk away with $250 and a clear referral.
You cannot leave this page worse off than you arrived.
Honest scarcity: We only accept 4 new MVPs per month to protect quality. Claim your slot before we book into the next cohort.
Answers to the questions you should be asking.
Everything you need to know about our AI-powered development process
We flag it the day we see it, quote the delta transparently, and you decide. We never invoice a surprise.
You do. It lives on your GitHub from day one. You can fire us anytime.
You can hire us on a retainer, hire your own in-house team and we will hand over the codebase cleanly, or just take the code and run.
Because hourly rewards developers for going slow. Fixed price rewards us for shipping.
Yes. We sign NDAs before any scoping call. Send yours or use ours.
We do rescue projects. We will scope the rescue effort separately from new work so you know exactly what you are paying for.
