I’m proud to announce that Antioch has raised $32 million in Series A funding, led by @GreylockVC with participation from @A_StarVC, @Category_VC, @BoxGroup, @IcehouseVenture, and angels.
Physical AI is the defining technological and economic opportunity of our lifetime. Rapid advancements in intelligence and compute have brought us right to the precipice of this new era. What’s holding the industry back is development speed — iteration is hardware-bound, testing is slow and costly, and data is scarce.
We founded Antioch with the belief that scaled, high-fidelity simulation is the solution, and will push us into the physical AI age. Autonomy teams use Antioch to accelerate development, test and validate their systems at scale, and generate massive quantities of synthetic training data.
We’ve seen the development velocity that Antioch brings to advanced manufacturing, humanoid robotics, smart security, model training, and more. Now, we’re scaling rapidly to put Antioch in the hands of every autonomy team.
Thank you to the wonderful customers, investors, partners, friends, and family who are on this journey with us.
Read about what we’re building in @Forbes (link in first reply) and tune into @tbpn today at 3:35pm ET to hear more.
We’re hiring across simulation, infrastructure, machine learning, 3D graphics, go-to-market, and operations.

Today, we’re announcing Antioch’s $32 million Series A, led by @GreylockVC with participation from @A_StarVC, @Category_VC, @BoxGroup, @IcehouseVenture, and angels.
While AI has drastically accelerated software development, physical autonomy has been constrained by slow, expensive hardware-based development. Antioch enables physical AI teams to build, test, and validate systems at the speed of software.
We’re proud to be working with leading teams including @amazon @ring, @NVIDIARobotics, and @nebiusai as we make scaled, high-fidelity simulation the standard for physical AI development.
Our sincere thanks to the legion of investors, customers, partners, and advisors who are making this step change possible.
We’re scaling rapidly and hiring across simulation, infrastructure, machine learning, 3D graphics, go-to-market, and operations.

Progress in the mind of Ryan Petersen
Episode 2 gets into wild territory 🍿
When supply chains shut down in 2021, @typesfast rented a boat, hit the water, and tweeted what he saw in the Port of LA. The mayor changed the law that same day.
On Progress, we get into tariffs, Black Death, AI religion, and how to make manufacturing high status again.

I rarely do interviews or talk about my personal life, but I made an exception for the team at @firstround.
Their writer spent hours at my house. We talked about why I started Lenny's Newsletter, what motivates me to keep building it, and a lot of things I don't usually share publicly.
It's an intimate look at what my life is actually like outside of what most people see on the podcast.

10 years ago, @paraga and I were working together to introduce ranking to Twitter’s timeline for hundreds of millions of consumers. Now he’s started @p0 to build infrastructure for a very different kind of user: AI agents. And in a full circle moment, we’re able to work together again, as @firstround invested in his seed round last year alongside @khoslaventures and @indexventures.
Parag and I had a chance to sit down for a great conversation last week (his first interview since leaving Twitter!). It was a fascinating reflection on what he learned and what he’s doing differently.
We dig into:
- The transition from CTO → CEO → Founder
- What he was *really* thinking when all the Twitter drama was going down
- Why he chose to be a founder (vs. take another big role)
- How he landed on the idea for Parallel
- What fundamentally changes when you’re designing for AIs vs. humans
- How he thought about fundraising and building his early team
- How working with customers like Clay shaped Parallel’s earliest products
- The case for building “slow” APIs, and the advice he got from @patrickc
- His takes on the modern agent stack and how evals need to evolve
And much more!
Immensely proud to be able to partner with Parag and the entire Parallel team. They’ve made incredible progress in a short amount of time and I can’t wait for more folks to start playing around with the APIs they’ve built.
The full conversation is below, as well as more details on what Parallel is up to.

After 12+ years of publishing tactical company building playbooks on The Review, we’ve decided to start a brand-new publication, dedicated to AI actually working in production. We're calling it Applied Intelligence.
The aim is to close a gap we’ve spotted: Everyone's talking about AI transformation, but few are sharing the actual mechanics of how it’s unfolding inside companies.
We’re incredibly fortunate that our first piece is with @fnthawar from @Shopify, going deep on how they turned @tobi’s famous memo into reality. There’s lots of interesting real-world workflows, behind-the-scenes demos, and non-obvious insights that they’ve picked up as they’ve pushed everyone to build with AI first. (You can read it in full below.)
We’ll be sharing detailed new stories every week, so make sure you’re subscribed.
And if your company’s using AI in an interesting way internally that you think readers would find, feel free to DM me or email ai at firstround dot com.

The final surprise of AI April...
I'm excited to announce the launch of Lenny's Reads—an audio podcast edition of Lenny’s Newsletter.
Many of you have told me that you’d prefer to listen to my newsletter instead of read it. I’m excited to share that now you can.
Every newsletter post will now be transformed into an audio podcast, read to you by the soothing voice of Lennybot.
We’ll ship the podcast version of each post within 48 hours after it's published. Paid subscribers will hear the full post, and just like with the newsletter, free subscribers will get everything up to the paywall.
For a limited time, the first five episodes of this new podcast will be completely unpaywalled and available to all listeners. Get on it.
Listen now (and subscribe) here:

Most teams think they're blocked by resources. But they're usually blocked by assumptions. Challenge your constraints before adding more people.

The origins of Uber's "Greyball Program" controversy.
It ended in a DoJ investigation.
But it started with innocent intentions.
Zac retweeted
Uber's Greyball program was wild.
Says a lot about the culture that employees across countries were willing to go to these lengths.
They dodged city regulators at the same time they were lobbying them to change the rules.

Borrowed the mic for a very special episode of In Depth with the legendary @sgblank.
He dropped a can’t-miss playbook for founders building for the government buyer. “When you’re selling into government, everything you know about commercial sales you need to throw out.” 😬
