For months, I’ve been helping a close friend find a sperm donor. It’s extremely hard to find the right match, even with some significant $$ behind the search.

His problem is all too common: 1 in 6 American couples struggle to get pregnant and ~50% of infertility is male factor.

While researching, I learned that ~100k+ families/women are looking for a sperm donor, yet only ~1,500 donors are registered.

This is why we’re launching @PreSeedOfficial, a 1:1 donor matching service to recruit sperm donors for people looking to build families. Society needs more men to donate their sperm and help bring life into this world.

Here’s what most people don’t realize:

1. There’s a massive supply–demand mismatch. With no national registry, we can’t track sperm donations properly. Inventories for in-demand donors sell out fast. Directional estimates put ~100,000–150,000 families searching, with only ~1500 donors in the US - total. That’s approximately a 100:1 ratio.

2. It’s functionally unregulated. Beyond the basics health testing, there’s no binding oversight of offspring limits or cross-bank tracking. No one can say how often a donor’s genetics are used - or where. Under current guidelines, one man could technically father 10,000 kids.

3. Current sperm donation over-indexes on superficial traits like looks and basic health screening. What’s missing is better oversight and real, systematized values matching - things like IQ, key personality traits, (~40-60% heritable), risk tolerance etc. - the stuff that greatly shapes a child’s story.

If you’re a healthy man:
- You can help a family exist.
- You’ll go through appropriate medical screening and verification (no shortcuts).
- You’ll tell us about who you are - not just what you look like.
- You set clear boundaries and agreements with the recipient family up front.

If you’re a family:
- Tell us what you need.
- We help you find potential matches meeting your criteria.
- You’ll then work with a registered professional to initiate the screening and due diligence.

This isn’t about “disrupting” for the sake of it. It’s about fixing a very human bottleneck with transparency, values-matching, and more good people in the pool.

If you’ve ever thought, “I’ve been blessed with great genes” this is your moment. Help a family in need bring life into this world.

Men: add your name, no upfront commitment.

Families: tell us what you need.

Friends: share this so the right people see it.

SUPER excited to share I’ve just joined @EWOR_official as Head of Investments 🚀

The last 8 months has been full of more major plot twists (and magic) than I could ever have predicted - across all areas of life. And I have a very strong feeling this is just the beginning...

I want to surround myself with the smartest, most ambitious, boldest humans I can. People who are determined to change the world. The crazy bunch who are delightfully in love with the game of life. And EWOR is exactly that.

I was so impressed with the calibre & ambition of the team that when they asked me to join - there was no way I could walk away.

And as for the EWOR Fellows? Well, if my goal is to never be the smartest person in the room - let’s just say I’ve found the right room ���

P.S. The next chapter for me will be San Fransisco. It’s been on my hit-list for a while, and finally taking that step. So if you’re in town, let me know!

After 186,000 views on our call for sperm donors, the top trait that emerged among the donors was surprising...

Ambition.

And what's more, almost all of them are altruistically motivated.

A powerful combo that bodes very well for the next generation & society at large.
