Happy New Year to everyone! We hope 2023 will be spectacular for you all. We're back and ready to kick off the year with a fresh round of finance goodness in our weekly Tech Mafia series.

If you missed our previous posts, make sure to check the Twitter Mafia and Lyft Mafia articles. This week we dive into 22 phenomenal startups that have come out from the Stripe Mafia.

The formation of Tech Mafias is fascinating because brilliant minds and ideas exist in every company, so the opportunity to invest in the next big unicorn is likely closer to you than you think (and not exclusive to venture capital firms only).

Investing in fellow coworkers' startups, especially as a community or alumni group, is one of the best ways to get in on the best deals as well as support the ideas and ventures of people you love and admire. Who knows what's around the corner in your own network and community!
