Let's talk

About Us

For over ten years we've been designing and developing excellent products.
We introduce not just the code into the project, but all our expertise that is useful during the product lifecycle.
This is why we are impressively successful year by year.
  • Who we are
    4xxi's expertise has helped create successful start-ups and solved complex problems for more established mature organisations by building mobile and web applications.

    We are developers. We do not like bureaucracy and we do not play politics. We simply do our job and do it well, as our clients all testify. Each product we build we consider as our own.

    4xxi is among the world’s top-10 companies in the Symfony development quality rating, and in the top-10 Russian companies that work with React.

    We provide both technical and product expertise for our clients. That’s why the start-ups we have helped build so far have raised in excess of $100M in funding and gone on to build significant revenues streams and shareholder value.
