Early last year, Adrian, Nathan, Amiel and I started building Stride during our free evenings and weekends. Since then, along with the help of Kevin, we continued to grow, iterate and better the service whenever we could. Today, we're happy to announce that Stride has been acquired. We're confident and excited for the future of the company, and can't wait to watch it grow from the sidelines. Link
