💰 New: Featured Founders Fundraising

We’re launching a new section highlighting founders actively raising capital.

Every week I get flooded with messages from founders we’ve featured (and plenty we haven’t yet) wanting to share what they’re building, how fast they’re growing, what their revenue looks like, and who they’re raising from.

Some of those conversations are too interesting to keep behind closed doors.

With the founders’ permission, we’ll occasionally feature startups that are actively fundraising and give you a peek behind the curtain on what they’re building, where they’re at, and what their raise looks like.

Think of it as a curated founder-to-investor matchmaking section built right into the newsletter.

Back to the good stuff…

In this issue of the Stealth Startup Spy, here is what we will uncover:

• Serial PropTech founder modernizes how America's HOAs source contractors for the $100B+ a year they spend on major property projects

• Three-time founding engineer (Tidemark, Innovius Capital, Hippo Insurance) is now building her own venture

• Ex-CoreWeave CPO builds a trust layer for production AI

• Ex-LinkedIn VP who sold Connectifier to LinkedIn builds a robotics company in stealth

• Ex-Citadel quant engineer builds agentic compliance for trading desks

• And more…

Now let’s shine the spotlight… 💡💡💡

BidMyCommunity modernizes the process, helping communities source qualified contractors and make better, faster purchasing decisions.

Thank you for reading. If you liked it, share it with your friends, colleagues and everyone interested in staying ahead of the hidden developments in tech. Subscribe below and follow us on X / Twitter to never miss a company operating under stealth again.

Stealth Startup Spy is a data-driven newsletter for investors, journalists and tech enthusiasts interested in uncovering the next big move for key talent, real-time stealth company launches and technology advancements not in plain sight. We leverage the technology built at Gravity to shine a light on the hidden world of stealth startups.

🚀 We just launched a new newsletter — Company Launch Tracker.

We’re tracking company launches as they happen and surfacing the most interesting new founders and startups (yes, all outside of this stealth activity too). If you want to stay ahead of the curve, this is where you’ll find them first.

Right now we’ve got 5 subscribers: my wife, my mom, and that high school buddy who won’t stop pitching me his app. Be smart like them and get in early 👇

Subscribe to Company Launch Tracker

We run a live feed inside Gravity that tracks founders entering stealth and companies quietly exiting it.

What you’re reading here is about 1% of the stealth activity we pick up. The full tracker updates in real time as things change and new activity emerges.

If you want earlier access to everything, book some time with us to stay ahead.

In this issue of the Stealth Startup Spy, here is what we will uncover:

• Ex-Meta tech lead builds enterprise AI for insurance agencies and brokerages

• Ex-Stripe, Microsoft, and Facebook engineering lead across payments and credit infrastructure builds a new venture

• Ex-Apple AR engineer and MIT Media Lab neuro researcher builds a “couture house” for neural interfaces

• YC S24-backed Comfy Deploy founder, ex-Microsoft engineer, builds a new generative-media venture

• CoScreen co-founder and CEO (acquired by Datadog) builds something new

🚨Here’s the deal🚨This email has gotten too big. Exciting, but with more people following it, the edge diminishes. I’ve thought long and hard about what to do to preserve the value in the signals. I’m not sure about the final direction yet, but in the meantime I’ve been sending an email 48 hours earlier to a select group of paid subscribers. The feedback has been pretty positive so I’m going to open up the list for another 100 spots. To get signals early, Apply here!

Stealth Startup Spy is a data-driven newsletter for investors, journalists and tech enthusiasts interested in uncovering the next big move for key talent, real-time stealth company launches and technology advancements not in plain sight. We leverage the technology built at Gravity to shine a light on the hidden world of stealth startups.

Right now we’ve got 5 subscribers: my wife, my mom, and that high school buddy who won’t stop pitching me his app. Be smart like them and get in early 👇

Subscribe to Company Launch Tracker

We run a live feed inside Gravity that tracks founders entering stealth and companies quietly exiting it.

What you’re reading here is about 1% of the stealth activity we pick up. The full tracker updates in real time as things change and new activity emerges.
