This is what @tjack wrote in his memo about @paraga when we were contemplating the first round of @p0. As much as I enjoy giving Todd a hard time, he nailed it.

I’ve been watching @paraga build @p0 before most people knew it existed. @firstround invested in Parallel’s seed round, and I’ve personally known Parag for over a decade. He’s a singular technical mind, and one of the best company builders I’ve ever worked with. He has a unique ability to envision technology 2-3 years away that will have disproportionate value. When we invested in January 2024, Parag made a few bets that felt early at the time: agents would eventually use the web far more than humans, and the best way to build for that was to go deep on infrastructure and systems rather than chase the AI labs. He was right, and his bets are proving out faster than any of us expected. And it shows in the companies trusting Parallel to run their most critical workflows. Harvey, Notion, Clay, Profound, Opendoor, Modal, Baseten and over 100,000 developers — from AI-native startups to regulated enterprises — all building on Parallel. Today, Parallel announces its $100M Series B at a $2B valuation, led by @sequoia, more than doubling in five months from the Series A. Proud to have been there from day one. A lot more ahead. More details below:

After leaving Twitter, @paraga had no shortage of options. He passed on all of them. Instead of jumping into his next thing, he spent months trying to find a problem worth committing a decade of his life to. He kept coming back to a question: what does the web look like when AIs become its primary users? It requires a completely different infrastructure layer, built from scratch, for a customer the web never had before. Today, @p0 announced a $100M Series B at a $2B valuation. The company is 18 months old, and more than 100,000 developers — including customers like Harvey, Notion, Opendoor and two of the US’s leading P&C insurers — are building on Parallel’s infrastructure. We’ve had the opportunity to watch the team execute since their seed round. Congrats to Parag and the entire Parallel team.

Overheard from a founder today: It is the most exciting time to ever build a product as a startup It is the most existentially unnerving time to build a company

“Blank check founders” are the ones I’d fund pre-idea, no matter what it is. Snir Kodesh is one of them. I’ve known him for 5+ years through our First Round community: Angel Track, Eng Leaders Forum, PMF Method. His first company was acquired by Lyft, and he later went on to lead engineering at Retool. When he was ready for his next thing, we invested before he even had a specific idea. He ended up in a domain most founders wouldn’t dare touch — enterprise audit — but one he knows extremely well. Snir is deeply technical and innately commercial, a heat-seeking missile when it comes to finding a big problem and imagining the right technology to solve it. Today, Petual is coming out of stealth with $20 Million in funding. They’re bringing agentic AI to SOX testing, autonomously generating auditor-ready work papers in minutes instead of hours. Early customers, including S&P 500 and NASDAQ 100 companies across energy, SaaS and financial services, can see 68-80% efficiency gains on workflows that today eat hundreds of hours per quarter. $8 Billion goes to SOX compliance in the US every year, but that’s just the start. The broader audit opportunity is massive — and to tackle both, Snir built a team of folks from Stripe, Retool, Lyft and the Big Four who understand these problems from all angles.

Shachar Hirshberg and Dan Shiebler make offers to new hires within 48 hours of their first conversation. They’re building an AI-native security company, Artemis Security, that battles threats that move at machine speed (which, for AI-driven attacks, is often in seconds). So speed is naturally an important operating principle for them. They’ve assembled a team of 30 people in NYC in under seven months, which they’ve done by front-loading references, bringing candidates in for lunch with the full team, and managing most of the recruiting process directly themselves. Engineering velocity is often a hiring problem in this market, and these guys have figured out a system that lets their recruiting process move as fast as their product. Their engineers run multiple Claude Code instances simultaneously to ship features in parallel, nearly all of their code is AI-generated, and they’ve outrun their original product roadmap by seven months. But they still haven’t managed to find any candidates who use AI as heavily as the Artemis team does. That isn’t a dealbreaker for them, though — they’re only looking for people who want to learn, and they train everyone who joins to ship as fast as the founders do. Fresh off their $70M fundraise and launch out of stealth, I sat down with Shachar and Dan on In Depth to find out how they’re pulling all of this off. We also dig into: -Why they’re on a texting basis with every CISO they sign -Why AI is a death knell for legacy security platforms -How they maintain decision-making velocity in their relationship as co-founders

Was just reminded of this classic video this week. Many VCs specialize in empathy theater. Nodding along. Telling founders what they want to hear. I’m more of a “hey… there’s a nail in your head” investor -- and then I get to work to help you remove it. youtu.be/-4EDhdAHrOg?si…

Today, @Clay is launching Functions. And when we thought who should announce this to the world ... who better than arguably the best pizza chef in NYC? What are functions? Well, they're kind of like a recipe. OK I know it's a bit of a stretch but hear us out. Whether you're slinging pizzas or GTM workflows, it really does start with the right formula. You don't just make the world's best pizza dough once and then wing it from there - you need a recipe you can count on time and time again. Think of functions as your thin crispy base - the core Clay workflows you've been rebuilding manually from memory (waterfall logic, scoring models, signal sequences). Define your data once. Your team runs on it forever. Edit it centrally and it auto-updates everywhere. PS Lucali is near and dear to my heart. I went on one of my first dates with my now-wife there (and actually sat next to Beyonce and Jay-Z! Just two couples with great taste dining side-by-side!). Learn more here: clay.com/blog/functions

I thought this @Firstround Review article perfectly captured @lennysan's level of obsessive attention and discipline. And I especially loved this quote from Lenny's wife: “He flosses every night. And he uses a water pick during his morning shower. It represents who he is because of the consistency it takes,” she says. “Every night is one thing. But every morning, too? Who does that?”
Lenny Rachitsky@lennysan

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. Check it out: review.firstround.com/reluctantly-in…

Katie Burke spent 11 years at HubSpot, joining when it was a small private company and ending that chapter as the Chief People Officer of a public company. She then joined @Harvey and is now their COO. We got together to talk about human stuff in the world of AI.

We love working from our office! @firstround Capital (who has been one of our earliest and most trusted investors since the seed round) just did Architectural Digest Open Door-style video about our SF office (including our philosophy behind it.) I hope you like the tour!
Josh Kopelman@joshk

Recently, @ivanhzhao put words to something we’ve long believed: "The most meaningful things were never built alone. It’s always groups of people, building and believing until something clicks." So much of that work happens when people are together in offices, where ideas are discussed and tugged at and strengthened when people gather around them. Space influences how people “think together.” Today, we’re excited to launch a new video series about the stories behind the physical spaces the best companies inhabit, and what those spaces reveal about how great work gets done. It feels especially fitting to begin with @NotionHQ. We began our partnership with the company long before they had an office, or even a product. Join @akothari as he gives us a tour of Notion’s SF office

Josh wrote one of the very first checks into Notion back in 2013. They stood by us through some really rough periods, which made doing this video collab even more meaningful. We wouldn’t be where we are today without them.

So cool! Congrats to the entire @K2SpaceCo team!!
Karan Kunjur@KaranKunjur

I'm very proud to share that the team @K2SpaceCo has achieved Tier 2 Mission Success for Gravitas! Over the past week, we've: • Powered on our payloads • Activated our high power propulsion system and fired the thruster • Completed testing of our software system, including a software update With all of the satellite bus systems demonstrated and checked out, we will be transitioning to sustaining operations for the rest of the mission. This includes continuing our payload demonstrations while pushing the satellite bus systems to the limit to learn as much as possible for future missions. (And yes, this photo is real. Our thruster firing on orbit.) ---
