Last night 100 Jews gathered for our @mytechtribe Tech Shabbat at Novig HQ: some of NYC’s greatest founders, investors, engineers and operators.
In the room: people from Google, Microsoft, Amazon, Meta, Palantir, Airbnb, Figma, Pinterest, Lyft, monday. com, Asana, Payoneer, Upstart, Stripe and Databricks.
From Novig, Peregrine, Slash, StackAI and Kalshi, plus people from 25+ other startups, from stealth to Series B.
Investors from a16z, Left Lane, Primary, Upfront and Portal.
The room was packed with immaculate vibes and high-energy Jewish pride.
The message was loud and clear: Jews in tech want to find each other, and celebrate together.
Thank you to @j__fort and the Novig team for hosting us. and mazal tov again on the birth of a beautiful baby boy!
Wonderful vibes by @EinhornGabe, @DavidPawlan and all our other incredible cohosts.
Next one soon.

To all my friends who worked at Foursquare over the years (@MegletNY, @maxsklar, @david_rosenberg ... Crazy how many Tech Tribes OGs came from there!)
Thank you for what you built.
Social that makes real life more engaged, not less, and blessings for success in everything to come.
Foursquare was acquired last month. The outcome was disappointing. It's taken me a while to write this, but I think I'm finally done grieving it. Here are some thoughts on our final years, an effort to honor the team who helped build & maintain FSQ's legacy, and my attempt to finally get some closure. teendrama.substack.com/p/som…

Rabbi Yisroel Rubin, 78, Innovative Scholar Who Led Chabad in New York’s Capital Region.
When Rabbi Y Rubin got to Albany in 1974, he didn’t even begin with a synagogue or a community center. He went with matchbooks and a hot dog cart.
In time, he spearheaded the establishment of more than a dozen Chabad centers:

My friend @JulienReiman and I were texting about some upcoming excitement at @OpenAI , and he mentioned that he'd recently commited to putting on tefillin every day.
But today, of all days, he left home before wrapping.
As Providence would have it, I had reason to be nearby, and we wrapped.
He was kind enough to share this awesome OpenAI kippa for others to use in the future when they wrap!

Bullish on NYC
Bullish on @MyTechTribe
New York is becoming one of Databricks’ biggest AI hubs. 🗽
We’re expanding at 5 Bryant Park to ~120,000 square feet across five floors, including a dedicated Engineering and Research floor.
With teams building technologies behind Genie, Unity Gateway and CustomerLake, our momentum in NYC is only growing.

Can anyone help me get my mom into @Neko ASAP?

Sure. The students.
A good rule of history: if you find yourself opposing a student movement while siding with the ruling class, you're wrong. Every time, in every era, whatever the issue.
Readers added context they thought people might want to know
Student movements have not always been on the right side of history. Mao's student Red Guards persecuted hundreds of thousands. Students helped Castro and Khomeini rise to power, and Nazi student groups opposed the Weimar Republic.
