About LeanCode

LeanCode was founded in 2016 in Warsaw, Poland by Łukasz Kosman (CEO) and Jakub Wojtczak (CTO), starting as a team of six dedicated professionals focused on a single mission: building world-class Flutter applications. Today the company employs 80+ tech experts, including 40+ dedicated Flutter developers, making it one of Europe's most Flutter-dense engineering firms. LeanCode holds official Google Flutter Consultant status — a designation given to only a handful of firms worldwide — and organized Flutter Europe in Warsaw in 2020, one of the largest Flutter conferences globally with 500+ attendees. Their 100+ delivered products span banking and fintech (Credit Agricole), HR tech, healthcare, retail, proptech, and manufacturing. They operate across all Flutter target platforms: mobile (iOS/Android), web, and desktop. LeanCode has been recognised with Deloitte Technology Fast 50, Forbes Diamond 2024, and Clutch 100 Fastest Growth awards.

Why They Stand Out

Official Google Flutter Consultant — one of few agencies globally with this designation. Organized Flutter Europe conference, signalling genuine community leadership rather than just commercial Flutter work. Forbes Diamond 2024 recognition and Deloitte Fast 50 validate growth trajectory.

Ideal For

Enterprises and scale-ups seeking deep Flutter expertise across mobile, web, and desktop from a single team. Companies in banking, fintech, or healthcare needing a proven European nearshore partner. Teams looking to augment existing Flutter codebases with senior-level engineers.

Potential Drawbacks (Honest Assessment)

Warsaw timezone (UTC+1/2) requires deliberate scheduling for US West Coast clients. At 80+ engineers the team is mid-sized, which may limit capacity for very large simultaneous engagements. $25K minimum project size and $50-$99/hr rates are above budget for pre-seed startups.

2 Company Legitimacy

We check business registration, physical office existence, and employee headcount consistency across LinkedIn and other public records.

3 Code Ownership

We verify standard contract terms to ensure they offer "Work for Hire" agreements where you own the I.P. and source code upon payment.
