Greptile has raised a $50M Series B led by Menlo Ventures. The round values the company at $750M. Greptile reviews and tests more than 1% of all PRs opened on GitHub every day. Thousands of engineering teams including Nvidia, Coinbase, Decagon, and Vanta use Greptile as their independent and central validation layer. Fewer than 50 people, we are a small, talent-dense team of engineers and researchers in a quiet corner of San Francisco. If you’re interested in joining us, we’d love to hear from you.

Today, Ramp raised $1.85B at a $60B valuation. Seven years ago, Karim and I wrote our mission on a Post-it: “Save companies time and money.” Our mission hasn't changed. It’s just gotten bigger.

huge milestone!! thank u Marc for the original intro to Ali. you were totally right. Ali was sooo hungry when we first met. and is even hungrier today. i'll always remember our first few calls. we first met several years ago in June...and then a few months later he was apart an early (fwiw we are still early) Z Fellows cohort. the business has had its ups and downs but in those down moments... Ali always finds a way. Ali wrote this about himself to me four years ago when describing himself and the business: "Hi everyone, I'm Ali! I was born in Iran, moved to the U.S when I was 10 years old, and sucked at school (didn't even graduate middle school). I decided to turn things around Freshman year of high school: I got straight As, started my 1st company, and got into UC Berkeley for CS. Ever since, I've had two small acquisitions (cashbooksnow & peerlinc), and graduated Berkeley a year early to focus on my company: micro1. Micro1 is a 40 person talent as a service company. We help companies hire the best remote developers easily. We've recently raised a pre-seed round and I'm super excited to have it grow to be my 1st unicorn" proud to be Ali's first believer and investor in Micro1 and work with him. excited for what's to come!!
about 3 years ago, micro1 lost 60% of its revenue overnight and almost went bankrupt. today, i'm proud to share we've surpassed $1B annual run rate while remaining historically profitable. it’s been a special journey. we’re grateful for every struggle, moment, and person who has been part of it. we've taken a very untraditional path to get here. our core team is only ~180 people, spanning 14+ countries, and fully remote. many of our decisions sacrifice hundreds of millions of revenue and slow us down short term. but we believe they compound into advantages that are impossible to replicate long term. the long term is now. these are the 8 principles that made micro1 a leader in the data industry and will soon make us number one: 1.) human 1st AI: treat the tens of thousands of experts helping train models with absolute best-in-class care. our goal is to make AI training one of the largest, highest paying, and most enjoyable job sectors in the world. 2.) U.S. first: we refuse to work with adversarial nations, or export data that improves models against the interests of Americans. 3.) long-term research over short-term ARR: invest in deep research, products, and infrastructure for years from now, not just the next customer pipeline. 4.) proper incentives for intensely hard work: no arbitrary requirements like 996. inspire people to work extremely hard with outlier incentive structures instead of forcing weekend work. we’ve maintained close to 100% core team retention as a result. 5.) stay lean and global: we’ve reached $1B run rate with ~180 people, and intend to slow team growth significantly from here. exceptional talent is found around the world, and pedigree is the wrong thing to over-index on. 6.) execution alignment: company to retain a streamlined board so we can optimize for the next several decades, remain light-weight and dynamic, and take bold & calculated risks. 7.) abundant intelligence improvement: invest in building data generation models to make high-quality datasets and RL environments dramatically less expensive and more abundant. 8.) scale data on realism and horizon: realism brings the complexity of the real world into training models, while horizon extends how long models can work and how much complexity they can handle. both have enormous room to scale, and we’re pushing the limits of both. additionally: after surpassing $500M run rate this summer, we priced our Series B at a $4B valuation, alongside a ~$25M tender to give our early employees liquidity as we build for the long term. the round was led by Dream Ventures, a longtime supporter and one of our earliest investors, alongside Microsoft, Javelin, Flybridge, G Squared, Up Partners, and LG. we’re also grateful to be backed by incredible industry leaders, including Guodong Zhang (co-founder of xAI), Andy Fang (CTO of DoorDash), Igor Babuschkin (co-founder of xAI), Behnam Neyshabur (founder of Mirendil), Jerry Tworek (ex-VP of Research at OpenAI), and many more. data is on its way to becoming the largest industry humanity has ever seen, and we're certain this is just the beginning. best, Ali

i first met zain in july 2025. he was living in the tenderloin in sf paying $35 a night for a room. i remember really liking him and thinking the world would know his name soon... he did z fellows shortly after (and moved out of the tenderloin). he joined two other experiences we hosted as well that fall. every time we spent more time together....i felt like the world still hadn’t caught up. my favorite thing in the world is helping people before the world knows their names. a year or so later, zain is still the underdog....but i’m excited for people to see what he’s been working on. keep it up zain!!!

Listen Labs is joining @Salesforce! A year and a half ago we launched Listen, an AI platform for understanding customers, and it’s been a crazy ride ever since. Today, we work with some of the largest companies in the world, including Microsoft, Anthropic, and Sweetgreen. What started as an AI interviewer is now a full platform for understanding customers. Listen finds the right people, interviews them, analyzes what they say, and even simulates how they'll behave. Listen’s growth quickly accelerated and while we were raising our next round, we met @Benioff. Marc is a hero of mine. I've taken countless ideas from Behind the Cloud and watched him framemog every AI CEO on the planet. We're honored to get framemogged next. With Salesforce, we can bring Listen to every company in the world, much faster. To our customers, our mission remains the same.I stay CEO, @Florian stays CTO and the same team will keep building the product you rely on, now inside Salesforce AI Labs. Thank you for believing in us early. To our team, families, and everyone who believed in us before there was much to believe in, thank you. These years have been the most fun years of my life, and it’s still only just the beginning for Listen. Now back to work. 🚀

fun fact: first believer and wrote the very first check in @itsalfredw and @florian_jue they weren’t building Listen back then (circa 2022). they were building BeFake (pic)...then pivoted. keep listening as u scale :)!!
Today, Listen crossed $100M in funding. Building is easy now. Knowing what to build isn't. Our AI finds and talks to your users so you don't have to guess. See how Sweetgreen, Microsoft, and Replit use it:

Exciting news: @ListenLabs is joining @salesforce . When @itsalfredw and I first met, we dreamed of a world where AI was as capable as it is today. But we knew intelligence alone wouldn't be enough. It had to deeply understand the humans it's built for. That idea became Listen. Since we started in 2023, Listen has interviewed millions of people for companies like Microsoft, Anthropic, and Sweetgreen. I am so proud of the product and the team we built. Now that world is here. AI can build almost anything. Knowing what people actually want is the hard part. With Salesforce, when the transaction closes, we can bring that to every company in the world, much faster than we could alone. We're just getting started. Back to work!
