Lean Apps

Lean Apps is a Germany-based app and web development agency founded around 2018, when it appeared on Clutch's list of top mobile app agencies. The team comprises 40 developers, 5 designers, 3 scrum masters, 2 product owners, 4 data analytics specialists, and 6 DevOps engineers—60 people total. They've shipped 100+ apps, accumulated 10 million downloads across their portfolio, and worked with clients ranging from Fortune 500 companies (Bayer, P&G, Adidas, Allianz, BMW) to funded startups (Infinia Retail, Dress and Friends, Offermill). The company claims to deliver from idea to app launch in 6 weeks, positioning speed as their differentiator.

Services and capabilities

Lean Apps offers user experience design (UX testing, product design, design sprint workshops, mockups and prototypes) alongside app development. On the development side, they build with React Native, native iOS and Android, React JS, web applications, chatbots, voice assistants (Amazon Alexa, Google Dialogflow), blockchain, AR/VR, and wearables.

Their design sprint methodology is central to their pitch: they claim it helps identify multiple solutions to a problem quickly. Beyond product work, they also deliver Lean Innovation programs and Agile Transformations. They've completed 3 Lean Innovation programs and 3 Agile Transformations, though the source doesn't detail what these entail.

Notable work

Flixbus commissioned a web and mobile app with a POS system integrated to Flixbus's ticket pricing microservice. The solution was set to launch across all 20 EU ticket outlets and scale to 1,000 shops globally.

For Sri Lanka Telecom, they built an OTT/IPTV app enabling customers to subscribe to new channels. The client achieved a 10% revenue increase by pushing personalized ads and campaigns through the app.

Infinia Retail received multiple engagements: an iPad and mobile app improving in-store customer experience and reducing cashier queues, and later a self-checkout app for autonomous stores. Dress and Friends, a social fashion network, reached 150,000 downloads with the app Lean Apps designed and developed.

Other clients span Bayer (animal health, radiology, clinical trials), Schwan-STABILO (digital transformation), Red Dot (online design channel), De La Rue (security printing), Procter & Gamble (product content management), and others detailed on their case studies page. Most case study titles are redacted as "Confidential Engagement," limiting visibility into outcomes beyond the handful named above.

How they work

Lean Apps operates using design sprints and Agile methodology. The source does not specify pricing, contract lengths, or whether they work on fixed-price, T&M, or dedicated team models. They advertise a free app prototype for signups but provide no detail on engagement structure, minimum project sizes, or communication cadence. The 6-week "idea to launch" claim appears to be their speed benchmark rather than a guaranteed timeline.

Team and credentials

The team breakdown is explicit: 40 developers, 5 designers, 3 scrum masters, 2 product owners, 4 data analytics staff, and 6 DevOps engineers.
