Our experts shine in rapid prototyping and MVP development to quickly validate the idea and launch your application to the market.

  • Narrow Tech Focus

    LeanyLabs focused on Javascript Application Development. It helps with building highly-skilled dedicated teams and attracting rare professionals.

  • Great Developers

    The most valuable part of our company is the people. We take every hire seriously and usually conduct around 20 interviews for each position.

  • More Than Just Agile

    Getting feedback fast is crucial for startups. Thanks to CI/CD and automated testing, we can speed up development cycles. Critical features can go live in hours, way ahead of the usual sprints.

  • Build to Adapt

    We know that startups must stay dynamic to thrive. In situations of extreme uncertainty, we favor software designs with lower costs of changes.

  • Zero Communication Overhead

    Talk directly with your team members when you need to. We don`t like micro-management and wasting time on pointless internal meetings.

  • Always There to Help You

    Building strong, long-lasting relations is crucial for our business. We want you to succeed and grow with us. We`ll do our best to make it happen.

Our Services

Case Studies


Don't break your APIs!


Weather website with detailed weather forecasts, current conditions, tide predictions, radar, and weather maps for cities and places around the world.


Crypto projects directory that calculates dividend ROI for each listed project to help make better investment decisions.


I don’t see them as an outsourced solution, but more as an integrated part of our company.

I get the feeling that I can trust them and I’m really confident in their ability to deliver and make the right decision.

I am very impressed with the fact that I don’t need to predefine everything into a lot of details. I can point them in the right direction, and they will start to pursue it, and ask me whatever they need to in order to achieve the goal.

It is a very low touch engagement in a good way. It is not that they don’t communicate with us, but more in the way that they don’t require a lot of maintenance.
