YearEnd superheros

Co-founders are tax experts from Carta

Sean O'Keefe

CEO and Co-founder

After working as a tax expert and consultant, Sean joined Carta in early 2015. He started out as the Head of Finance & Analytics and eventually transitioned into a software development role. His insights into tax accounting helped Carta gain footing in a competitive space.

Jared Hobbs

CTO and Co-founder

Jared joined Carta as one of its first engineers in 2013. He scaled the platform on the frontend, backend, and everything in between. His experience integrating with other platforms, most notably the IRS', prepared him for what he does today.

We believe that everyone should have access to tools that help them understand and optimize their equity and taxes.

Data protection

We’re serious
about security

The protection of your data is top priority at YearEnd. We use bank level encryption to store your information and our transmission protocol exceeds IRS standards.
