When it comes to hiring, it’s easier to tame a reckless hustler than it is to instill that dawg in someone

Enhorabuena al @MalagaCF y a toda su afición por su regreso a la Primera División. ¡Felicidades!
Wow they really are taking no prisoners

🚨 BREAKING: Major antisemitic arson attack in Golders Green, London destroys all ambulances (at least 4) of Hatzola Northwest — a volunteer Jewish emergency service providing 24/7 medical aid. @Breaking911 has seen footage of the attackers.
Arrived to SF in November - for no reason whatsoever, having only met us a day after we arrived, Niko hooked us up with meetings all round.
I think the only thing that exceeds his track record is his kindness.
After 15 wonderful years @generalcatalyst I am moving on to new adventures. The best days for GC are ahead! Super grateful to every single one of my teammates that I had the fortune to work with over the years. I learned a lot. Very thankful to our limited partners too for their long-term support. Equally importantly, it's been the privilege of a lifetime to work with so many inspiring tech startup founders from the very early days.
This week we hit #1 on the App Store.
I think very few people have fully grasped how AI enables new players like us to compete in the bigger leagues without drowning in some of the costs that come with scale.
Take moderation as an example:
Our platform processes 5M+ messages a month from ~200k users. As you’d imagine, the 5M+ messages are riddled with spam, malicious actors, impersonators, and much more. We also run identify verification for users who want to message people outside their circle (simple selfie with liveness check). Roughly 30% of our users verify themselves.
Pre-AI:
- Moderation team (outsourced): we’d need 3 people. Avg salary $20k. Cost $60k
- Identity verification: 60k users x $0.17 a verification if using an external provider. Total $10.2k (+ set up fees etc. But let’s assume it’s $0)
Total cost: $70.2k
Post-AI:
- Set up 4 AI moderation agents
- Set up 1 Identity Verification agent
Total cost in 2025: $3.5k (99% of it one of the 4 AI moderation agents, a super light model that reviews all messages)
That’s a 95%+ reduction in costs. And no hiring process, sick days, holidays or employee onboarding. I can fine tune models at 3am and they are ready to go at 3.01am.
This is just one example. We’ve got dozens to share.
Very excited about the future.
My dad discovered this guy in a random textiles fair in China 20 years ago when he’d just started off. My Bar Mitzvah’s kippot were some of the first his factory produced.
Fast forward to today, David has a complete monopoly over the Kippah market.
Insane stuff.
A Guangzhou supplier has become a multi‑millionaire by selling custom kippahs to Jewish American customers seeking unique designs for weddings and bar mitzvahs.
The entrepreneur tapped into overseas demand for personalized yarmulkes, offering tailored styles and bulk orders that appeal to celebrations and community events.
Onwards
The @edenblockvc portfolio just keeps GOING. Props to Equals for the incredible growth over the last few months. Proud of @equalsbento & team on the relentless effort of disrupting a huge industry.
#2 music app after @Spotify, and we’re still going.

Equals has unlocked virality 🧘♂️
You’re overanalysing this dip. Every Trump tariff sell off is temporary. But his thirst for market ATH is forever.
Terrible payroll numbers today. The Fed's only goal right now is to keep Americans in the job market - with no regard for inflation (already way above target).
Expect more cuts and rampant inflation as a result - great time to own assets.
This will run until inflation gets so bad we'll think we're reading Venezuela's CPI, at which point we'll have a sharp reversal and we'll all be left screaming for our mummies.
