if you’re given $50k and your first instinct is to start a company, you’re already a founder. you’re obsessed with a problem. you have a perspective most people don’t. building feels more like play than work. if that’s you, we write $50k fellowship checks to help you go faster. apply ↓

Congratulations to Adam and team for raising BoostVC Fund 4. Adam was the first venture capitalist to believe in us. For the longest time I was convinced he invested in Sonalight because we were the lamest company in YCW12. I later realized he was playing the long game with us as founders. He was excited when we pivoted to Amplitude and the rest is history. Adam sees incredible founders and markets before anyone else does and goes long with them. Congratulations on BoostVC Fund 4!
We are proud to announce our fundraise for @BoostVC Fund 4. I'm partnered with amazing people who are all aligned on making Sci-Fi a reality! @BraytonKey and @MaddieCallander! One step closer. Coffers are filled. Now need to deploy into legends.

Speaking of AI scientists - we quietly built and shipped one. For life sciences, called Tater. It doesn’t do all the things yet, but what it does is pretty mind-boggling.

I’m thrilled to announce our $3.3M seed fundraise and the launch of Slant, the AI-native CRM for financial advisors. We’ve seen firsthand how automation can transform an advisor's business, and we are excited to take it to the next level. Over 1,000 advisors use Pageport every day, and as we worked with our customers, it became clear that everyone was working in outdated legacy CRMs— forced to buy dozens of add-ons to get their job done efficiently. It’s time for an upgrade to advisor CRMs— Slant is built with AI front and center, designed to help advisors build better relationships at scale. If you’re an advisor or want to be part of the team helping 20 million Americans get the financial advice they need, schedule a demo or apply to one of our open roles!

Founders: MoldCo (@BoostVC co), is offering founders a free biotoxin blood test. Many founders are unknowingly being exposed to mold toxins which cause brain fog, fatigue and poor sleep. For the first 20 founders 👉 Email [email protected] with subject line "Boost VC - test"

Deep Tech Demo Day is coming up April 2nd - Great way to see the pulse of what's happening in Deep Tech. Calling all Seed / A investors, RSVP here: demoday.boost.vc/
Based on deals we are seeing, there is an obvious gap in the Deep Tech - Seed Stage market. No one writing the $4-10m investment check. Someone is going to do great with a fund focused there.
