The verdict in three sentences
In Miami in 2026, you go from idea to MVP in 90 days with a clear plan: 2 weeks of framing, 3 of design, 6-7 of development, for USD 25,000 to 60,000. Success is not about the number of features but a minimal scope that proves a single value hypothesis. Set your activation metrics and a budget to acquire your first 100 users from the start: without them, even a beautiful product stays invisible.
The 90-day plan, week by week
A realistic schedule guards against the classic trap: adding features instead of validating the essential. Each phase has a deliverable that gates the next.
| Phase | Weeks | Deliverable | Budget (USD) |
|---|---|---|---|
| Framing | 1-2 | Scope, personas, metrics | 3,000 - 7,000 |
| Design | 3-5 | Clickable mockups, flows | 5,000 - 10,000 |
| Development | 6-11 | Working product, payment | 14,000 - 36,000 |
| Tests + launch | 12-13 | QA, go live | 2,000 - 7,000 |
| 90-day total | — | MVP in production | 25,000 - 60,000 |
Payment integration (Stripe, and mobile wallets for cross-border) belongs in the MVP: it is the channel that proves willingness to pay, not an option.
Defining the minimal scope
MVP discipline is about cutting. A platform that does one thing perfectly beats a product that does ten halfway.
| Element | In the MVP | Deferred after validation |
|---|---|---|
| Core workflow | Yes | — |
| Payment (Stripe) | Yes | — |
| User account | Yes | — |
| Basic dashboard | Yes | — |
| Native mobile app | No | Yes, phase 2 |
| Loyalty program | No | Yes, phase 2 |
| Multi-language | No | Yes, per traction |
| Third-party integrations | No | Yes, on client demand |
Activation metrics and acquiring the first 100 users
Launching without measuring is flying blind. Define before launch what an activated user is and what it costs to acquire one.

Mini case study
Daniel, a founder in Miami, wants to validate a platform matching contractors with homeowners. MVP scope: profiles, quote requests, deposit payment via Stripe. Budget: USD 42,000, delivered in 88 days. He allocates USD 2,000 to acquire the first 100 users, i.e. a CAC of USD 20. With a 32% activation rate and 8% of requests converted to a transaction at USD 15 average commission, he proves willingness to pay and prepares a credible seed raise before even spending his full product budget.
FAQ
Is 90 days really achievable? Yes, provided you freeze scope at framing and resist additions. Overruns almost always come from mid-course feature creep, not from the technology.
Why integrate payment in the MVP? Because a B2B or marketplace MVP without payment cannot prove users are ready to pay. Stripe integrates in USD 3,000-6,000 and gives the clearest signal.
What is the minimum budget for a serious MVP? Plan at least USD 25,000 for a sellable product. Below that you get a prototype or mockup, useful to test appetite but not to collect revenue.
Do I need a mobile app from day one? Rarely. A responsive web app covers the MVP at lower cost. A native app (USD 12,000-30,000 more) is justified once traction is proven.
How do I acquire the first 100 users? A mix of targeted Meta Ads (USD 800-2,000), outreach and word of mouth. Aim for a CAC under USD 30 and measure activation before scaling budget.
