We design and develop
products for the web.

We are an agile team of designers and developers who write
lean software to grow your business

What we offer

  • Quality

    We love pair programming, peer reviews, test-driven development, working and contributing to open source, and applying design patterns.

  • Productivity

    We release early and often so that you can see progress every week. We are all about rapid prototyping and rapid development.

  • Testing

    With our test-driven development process, our code is not complete without thorough integration, functional and unit tests.

  • Lean Product Consulting

    We will find your riskiest hypotheses and help you define your product's business model. We will build experiments to help you grow faster.

  • A Reliable Team

    We provide software development services to scale your team. Increase your software development speed without sacrificing quality.

  • Product Design

    We will design and implement your Minimum Viable Product. Our goal is to take your vision and build an elegant solution to your problem.

Our Clients

  • We have worked with Ombu Labs on a number of software development projects, and have been very satisfied with the results. The developers at Ombu Labs are knowledgeable, motivated and easy to work with, and go above and beyond our expectations for each project. They have been an invaluable resource to us and we look forward to continuing to work with the Ombu Labs team on future projects.

  • Having an external person working on Checker Cruncher was really useful for me. It helped in terms of accountability and having a second pair of eyes for things like testing, bug-finding and stylistic choices.

  • Ombu Labs exceeded our expectations. They went above and beyond and tried to help out even when the contract was up. Ombu Labs was willing to integrate with our team, and worked with the Junior Developer on our team to get to full productivity.

  • Recently, the team at Ombu Labs helped us increase the performance of our mobile app backend. We found their approach to be smart, methodical, and very effective. Their team is highly skilled, they communicate well, and they are a pleasure to work with. I'd gladly work with Ombu Labs again.

  • I really appreciate how Ombu Labs was able to carry things forward when I wasn't available to provide input. Knowing that their developers were able to write code, handle code reviews and keep everything together was really helpful.

  • Ombu Labs executed a full upgrade of our application from Rails 4.0 to 5.1, including preparation for an eventual 5.2 upgrade. The team adapted to our environment and kept a clear focus on the goal, resisting the temptation of feature-type distractions. Their effort allowed us to keep up to date with Rails versions without detracting from progress on other goals.

  • It is a rarity to find transparency, thoughtfulness and a superb quality + value equation in an outsourced digital tech team. Ombu Labs was able to bring my vision to life on-line seamlessly, despite the usual start-up constraints of small budgets + short lead-times and high output expectations. Ombu continues, months post-delivery, to stand-behind their product and over-perform from a client services POV— a fact which makes them our digital agency of record.

  • When we interviewed Ernesto for a short term contract project I told him that as the most expensive applicant he would be expected to produce the highest quality of work. Over a year later he and Mauro are an integral part of our team. In addition to producing high quality code they also suggest improvements to our development processes and mentor our new engineers. I would definitely recommend Ombu Labs to a friend in need.
