5 Weeks. 3 Iterations. $80k Pre-Seed Funding Secured.
A founder came to Esseal with a pre-seed concept: a location-based discovery app for the informal local businesses that Google Maps has never indexed — the cobbler on the corner, the roadside tyre shop, the food stall that moves. We built the MVP in 5 weeks. The final iteration was presented at the pre-seed round. The round closed.
The Gap Google Maps Has Never Filled
Google Maps works well for registered businesses with an address, a phone number, and a presence online. In dense urban markets across South Asia, that describes a fraction of the actual local economy. The cobbler who sets up at the same corner every morning. The tyre puncture shop with no signage. The cigarette vendor, the ad hoc petrol station, the food stall that's been in the same spot for fifteen years but has never appeared on any map.
These businesses exist in the knowledge of the people who live near them — and nowhere else. The founder's idea was to digitise that knowledge: a discovery app that surfaces local informal businesses to nearby users based on GPS proximity, without requiring those businesses to have a website, a Google listing, or any digital presence at all.
He came to Esseal at pre-seed stage with the concept, a clear target market (Lahore, Pakistan), and a round to close. The ask was a working MVP that could demonstrate the core mechanic to investors.
The Feature That Made Investors Take Notice
The core discovery mechanic — browse nearby businesses by category, navigate via one-tap Google Maps integration — was table stakes. What differentiated the product was the proximity alert system on the vendor side.
When a user navigates to a business and comes within 100 metres, the vendor portal sends a real-time ping to the business owner: a customer found you through the app and is on their way. For informal businesses with no visibility into how customers discover them, this was a fundamentally new kind of signal. Proof that the app was driving foot traffic. A reason for vendors to care.
This mechanic — the closed loop between user discovery and vendor notification — was the insight that made the MVP compelling to investors, not just functional. It demonstrated a network effect: the more vendors join, the more useful the app becomes; the more users arrive, the more valuable the vendor data becomes.
Flutter MVP Development — Two Apps, One Backend, Five Weeks
A complete product: consumer app, vendor portal, and Rails API — built for investor demonstration and closed beta.
Consumer Discovery App
Flutter mobile app for iOS and Android. GPS-based location detection, browsable directory of local businesses by category, open/closed status, distance from the user's current position, and one-tap Google Maps navigation to any listing. Designed for the informal economy — no internet presence required from the business to appear in the app.
Vendor Portal
A separate Flutter app for business owners — also built on the same Rails backend. Vendors manage their listing details and receive real-time proximity alerts when a customer navigates to their location. The portal gives informal businesses their first direct signal of app-driven foot traffic — a compelling data point for both vendor retention and investor narrative.
Rails Backend & 3-Iteration Process
Ruby on Rails API handling location data, vendor listings, and the proximity alert logic. Esseal ran three full iterations over five weeks: iteration one established functional core logic; iteration two addressed UX and edge cases; iteration three delivered investor-presentation quality. The third iteration was the version presented at the pre-seed round.
The Outcome: Pre-Seed Round Cleared, Seed Round in View
The MVP delivered by Esseal was presented at the pre-seed round. The round closed. The client secured $80k in pre-seed funding — enough to move the product into closed beta and begin the next phase of development.
The platform is currently in closed beta. A seed round and Series A are planned for 2026 as the product scales beyond the initial market and the vendor network grows.
This is what an investor-ready MVP looks like: not the most feature-complete version of an idea, but the most convincing one. Five weeks of focused, senior-led engineering — three iterations that stripped the concept down to what investors needed to see, and built it well enough that it stood up to scrutiny.
Frequently Asked Questions
Can you build a Flutter MVP for a pre-seed pitch?
Yes. Esseal built a full Flutter MVP — user app, vendor portal, and Ruby on Rails backend — in 5 weeks across 3 iterations. The final iteration was presented at a pre-seed round and secured $80k in funding. We build investor-ready MVPs that demonstrate the core concept without over-engineering the first version.
How long does it take to build a Flutter app MVP?
Esseal delivers Flutter MVPs in 4 to 6 weeks. The first week produces a functional but unpolished core experience. Weeks two through four address UX, edge cases, and presentation quality. The final phase covers QA, device testing, and investor-facing polish. For this project, the full MVP including a vendor portal was complete in 5 weeks.
What is included in a Flutter MVP from Esseal?
A standard Flutter MVP from Esseal includes iOS and Android builds from a single codebase, a Ruby on Rails API backend, core user flows implemented and tested, basic admin or vendor-side tooling if required, and a production-ready build suitable for investor demonstrations or closed beta distribution.
Can you build both the user app and the vendor or provider side?
Yes. For this project, Esseal built both the consumer-facing discovery app and a separate vendor portal — also in Flutter — that gave business owners real-time proximity alerts when a customer navigated to their location. Both apps shared the same Rails backend.
Pre-Seed Stage With a Mobile App Idea?
We've built investor-ready Flutter MVPs in 5 weeks. Senior-led, no throwaway code, and a process built around what you need to close the round — not just ship something.
