About Us

HTI Labs was established five years ago with the intention of bringing new perspectives to challenges both within finance and other industries. The common theme was innovation and taking best of breed solutions in an industry and taking those concepts in to new areas.

The Directors come from an investment banking background and were building front office risk systems that handled very large data sets and massive calculation farms. It's fair to say that we were working on ‘Big Data’ and 'Cloud' challenges before the terms were invented. Since then the team has grown with experience across industries.

We have worked on initial idea generation, architecture and through the entire development life-cycle. We've experienced substantial growth over the last year and have successfully delivered results on all the projects we have been engaged in.


Where we work

We are London based but have worked internationally for substantial periods. Working with us can be both onsite with clients and/or offsite in our facilities. Increasingly clients have been confident in our reliable delivery approach and have asked us to carry on development whilst giving some of their desks back!

If you're not sure whether we can help please contact us and we'll be in touch to discuss it with you.
