Client Overview

A well-funded startup based in Germany aimed to launch a peer-to-peer (P2P) car-sharing platform focused on electric and luxury vehicles. The founders had a strong business vision but needed a technology partner to build the entire platform from scratch, including mobile apps for renters and car owners, and a robust backend to handle bookings, payments, and insurance.

Problem

The client needed to rapidly develop and launch a Minimum Viable Product (MVP) to prove their business model to users and investors. The platform had to be highly secure, instill trust between users, and provide a seamless, premium experience to stand out in the competitive European market.

Key Challenges

Building a complex two-sided marketplace:

(car owners and renters).

Integrating with European-specific payment gateway:

and an "insurance-as-a-service" API.

Implementing a multi-layered user verification:

and trust system.

Delivering a polished, high-quality MVP:

within a tight 6-month timeline.

focusing on delivering the highest-priority features first.

Built the backend using a scalable microservices architecture:

on Google Cloud Platform.

Developed native iOS (Swift) and Android (Kotlin) apps:
