the story

Our founders graduated Yale during the financial crisis of 2009 - and entered a job market where new grads had to create opportunities for themselves. Lionheart Software was created to help this new type of small, scrappy company launch great products – and we’ve been helping startups get off the ground ever since.

We are experts in creating foundational tech for startups - since before we got started, these types of companies & products just didn’t exist. It’s hard to remember, but in 2009, most companies weren’t based online – and hardly anyone had smartphones! We were one of the first to build mobile apps, and over the past decade, have honed our approach to building web and mobile products from the ground up.

“The lean startup” was a theory in 2008, and a reality in 2009. We were there from day 1.

We make big ideas come to life.

    Time to think big.
