Fixy — Marketplace for Auto Services
From zero to investor-ready MVP in 3 months: a two-sided marketplace connecting car owners with mechanics.
My role: Product Designer (solo) · Team: founders + developers · Timeline: 3 months · Method: Lean Startup + Design Thinking · Platform: Web + Mobile
01
Goal
Design an MVP from scratch that proves the product idea to investors — fast, on two platforms, for two very different audiences.
02
Challenge
  1. Two audiences, two scenarios — mechanics manage requests and certificates; car owners create orders. One product, two mental models.
  2. Only 3 months — from the first wireframe to the investor demo.
  3. No ready-made solutions — no design system, no patterns, no legacy.
  4. Investors as a second “user” — the MVP had to sell the vision, not just work.
03
Research & Drafts
I studied competitors and their weak points, collected the first wireframes, decomposed tasks and managed the work on a Kanban board. This gave the team a shared picture of the scope from day one.
04
User Flows
I mapped two flows — for mechanics and for customers: registration, orders, search, and payment. The structure of the steps is simple and transparent: each step answers one question.
05
UI Library
With no time for a full design system, I assembled a lean component library: uniform styles, fonts, colors, and icons. It kept two platforms consistent and let me ship screens fast.
06
Prototype & Landing
The clickable prototype became the core of the investor presentation. I also designed a landing page for first-time users: “Make more money with Fixy” for mechanics and “Skip the drive to the service center” for customers — one product, two value propositions.
07
Results
MVP designed and shipped in 12 weeks — solo designer. The prototype played a key role in the investor pitch. Landing, product, and mobile: one visual language across all touchpoints.
08
What didn't work out
Not enough time for usability testing. The mobile version required more in-depth development. Some features were moved to the backlog.
09
Reflection
I quickly linked design and business goals. The balance of simplicity and functionality became the core of the product. Next time — more user testing, earlier.
