Hey, we're Alex and Bart
We're Alex Cohen (Sr. Director of Product at Carbon Health, founded CommandDot and Birch; acq. by Even Financial) and Bart Macdonald (Founding Partner at Bloom Equity Partners, repeat venture backed CEO).
On evenings and weekends we invest $50k - $150k in early stage startups out of our angel fund, which is backed by ~150 rockstar LPs. Over the past 3 years, we've invested $5m across 75+ startups.
What we invest in
We like to invest at the earliest signs of traction, which typically means partnering at pre-seed or seed. We have a preference for products in market with power users and early signs of monetization.
Partnering at this stage is exciting for us as operators ourselves - we hop into the weeds with our founders to help them figure out which products to ship, recruit the best early-stage talent, find their first power users, and raise follow on capital from the top investors.
While we love meeting all remarkable founders solving hard problems, we do gravitate to those building in the future of digital health, fintech, AI, and enterprise SaaS (where we have the most experience & value to add).

What our founders have said
"An investor's job is not to run your business, or manage your day to day operations. Instead, an investor's role should be to optimize your chances of success through their actions. Bart and Alex have achieved this through their introductions to additional investors, brainstorming sessions, and go to market conversations. We would not be where we are today without their impact."
Michael Vega-Sanz, Co-Founder of Lula
"I can't recommend enough Bart and Alex as investors. From advice on fundraising, marketing, or just operations, they always have my back when I need them."
Julien Delange, Founder of Codiga
"Bart is a masterful mentor to me as a first time founder. He has relentless expertise in cutting through the fluff to get to the heart of what really matters. I'm proud to have him as part of the Cuckoo journey."
Alexander Fitzgerald, Founder of Cuckoo
"Bart & Alex have been one of our most value-add investors beyond just capital. They've helped us with hiring, marketing, and fundraising, all of which they've done successfully as operators."
Rob Koyfman, Founder of Koyfin
"As a first time founder, it's invaluable to have operators to help bootstrap your fundraising and help guide your business. Many folks claim they are operators and yet so few are. Alex and Bart are part of that rare category and we are extremely fortunate to have them in our corner."
Hiroki Butterfield, Co-Founder of Butterfly Labs
