Scaling is a way of life.

We are Integritas

Your partner in software product development

Product Strategy

While we build software, you sell products. We think through your product strategy alongside you, ensuring we build the right at the right time. From initial concept to launch, and your road map beyond, let’s collaborate to plan feature and bring stability to software product development.

User Experience

Your products shouldn’t require an instruction manual. We aim for an intuitive product experience for your customers, and our Agile design process enables you to test features early with your customers, even before the product is built.

Software Development

In short, we build web apps, mobile apps, and enterprise software. Front-end, backend, database architecture – and everything in between. While we often build full custom solutions, we also look for existing products and services that can be integrated to save you substantial time and money.


Preparing your application for launch requires the right server architecture. Our DevOps engineers will create a scalable solution for hosting your application that balances performance and cost.

The Difference

What sets Integritas apart?


We only form partnerships with customers.  Beyond a mere vendor, we want to be your development team – a true extension of your team, from product to UX and development.  Leverage our expertise in every area from concept to launch.  As your development partner, our long-term success is tied to yours.

Complete Transparency

As a partner, you have complete insight into our process, contact details for every team member working on your product, and visibility for every hour spent on your product. We are an open book, and have nothing to hide.

Dedicated Teams

Our entire team is experienced and on staff, working on various projects while keeping up to date on new technologies and development frameworks.  Our product, UX, and account management teams are based in the U.S., and our development teams reside in Brazil and Sri Lanka.

Product Focus

While any development firm can build whatever the customer wants, it takes discipline to realize that a sound product strategy brings order to feature chaos and predictability to other areas of your business.  We proactively drive product planning and roadmap discussions to bring you a peace of mind.

Agile Process

Our Agile software development methodology enables software projects to be executed with less wasted effort, reduced customer cost, and on a faster overall schedule.  We want you to “see and hold” versions of your product as fast as possible to garner early feedback from your beta customers.


By leveraging our mix of U.S.-based and overseas teams, we are able to provide an extremely cost-competitive hourly rate.  We work on a time & materials basis, meaning that we invoice monthly for the hours applied to your project, with time reports sent each week.

  • Integritas built us a web app and they had all the experience around the table and on the calls to move things quickly. I appreciate they didn’t run things through an account manager and I could actually talk to the team doing the work!

    Founder and CEO, Mass Relevance

  • For over 5 years I have counted on Integritas to deliver excellent and cost-effective software development staff augmentation services. Over that time, Integritas staff became critical members of our team, with transparent and efficient collaboration between Sapling Learning employees and outsourced team members. Integritas was a necessary and important component for taking our unfunded fledgling startup through funded growth leading to acquisition. Integritas is a great solution for any software venture, and Paulo is a great business leader to work with.
