[B@B 10 YEAR ANNIVERSARY] 🎊
10 years ago, a group of Berkeley students came together to learn about Bitcoin and educate each other on a technology they believed could change the world.
They probably didn’t know that, a decade later, that little group would blossom into one of Berkeley’s top tech communities and bring together some of the most ambitious, thoughtful, kind, and absolutely cracked people we know.
Over the last 10 years, B@B has been home to some insane startups and even crazier ideas. But more importantly, it’s given us lifelong friendships, unforgettable memories, and a ridiculous amount of laughter along the way.
B@B turned 10 this year, and one reunion simply wasn’t enough. So, in true blockchain fashion, we forked it, hosting anniversary celebrations on both coasts and bringing together alumni from across a decade of B@B.
Some highlights:
- A photo wall of 10 years of our most wholesome moments, walking down memory lane
- Custom engraved Ledgers for our alumni made by our own @DivijMot @createdbymason
- A tres leches “10 Years of B@B & Boujee” cake courtesy of former-pres @Ridddhiiii
- Lots of old lore, reunions, and questionable stories resurfacing
@CalBlockchain had a great time this weekend running Berkeley's Robotics Hackathon! 🦾

A team of three @CalBlockchain members! Couldn’t be prouder of @sanjayamirthraj @notolegv and @ajiang_xyz!!
Excited to announce @fliptexts’ $1.4M pre-seed, and that we’ve joined @a16z @speedrun!
When @notolegv, @ajiang_xyz and I started building in January, we were stunned at how outdated money apps still are. So we built the finance-expert friend we always wished we had: one that fits you, earns its place, grows into the job, and lives just one text away.
My financial life doesn’t look like anyone else’s. I’ve managed six figures for a school club, spent my formative years trading crypto, and I’m still too shy to ask my roommates to pay me back for WiFi.
Flip starts by automating my monthly roommate bill, checking my wallets before I think to, nudging me to use my Dunkin credit before my Amex benefits expire, making sure my retirement accounts are stable, watching my cloud bills, scanning to see if my Netflix membership is *really* worth it, and finding discounts on late night food delivery.
We're making sure that no matter what your goals are with money: saving more, or making more, Flip is there to help you achieve that.
Couldn’t be more excited to build this with our partners
