We are early stage investors who run a go-to-market program for founders.







EXCLUSIVE: startup Simple AI has raised $14M to help customers like Omaha Steaks boost sales with AI phone reps. Is AI ushering in a voice revival? We talked to founders @catheryn_li and @Zach_Kamran -- both former YC staffers -- about what's going on. upstartsmedia.com/p/simple-ai-vo…

Announcing Artie’s $12M Series A. When Robin Tang and I started Artie, the idea was simple: make it easy to deploy real-time streaming pipelines. Streaming pipelines used to be something only a few companies could afford to build. Guaranteeing transactional integrity, handling schema evolution, recovering from failures, and keeping latency low at scale is hard. Most teams limp along with brittle systems. But today, with AI systems that make decisions, trigger workflows, and interact with customers, stale data isn’t just slow - it’s incorrect. Real-time data is becoming non-negotiable. Today, companies like ClickUp, Substack, and Alloy, are processing 700B+ rows of data annually with Artie to power AI/ML workloads, customer-facing analytics, and operational systems. @artie_labs is a fully managed real-time data streaming platform. We move data across systems in real time - so teams can rely on fresh, accurate data to power AI products - without building or maintaining streaming infrastructure. We raised this round to double down on a simple belief: the next generation of data infrastructure will be streaming-first. Huge thank you to @daltonc and @Standard_Cap for leading the round, with continued support from @ycombinator, @PathlightVC, and incredible angels including @arashf, @bennstancil, @chrisbest, @charleshearn, and @lennysan. I also want to thank our team, customers, and partners for supporting our mission. And thank you to Chris Metinko and @axios for capturing the exclusive story. P.S. - If you want the same streaming infrastructure that Netflix and DoorDash have, but want to skip the multi-year build - reach out.


If we ever get an office I hope it vibes like this

I get asked a lot what it was like to work with Steve Jobs. Probably the biggest thing I learned is that there is no "good enough" when it comes to the basics: communicating, motivating, and most importantly, thinking. Steve was obsessed with the quality of his own thinking. He was able to generate a mental map of a problem space faster and more deftly than anyone I've known because he worked at it. Over the course of a career, that skill compounds more than anything else. Thanks for the conversation @jaltma

I love the description of Pixar as a miracle factory. How do you create the conditions to make special outcomes more likely? @ROWGHANI helped build Pixar, working closely with Steve Jobs and Ed Catmull in their golden era. He also worked closely with the Twitter founders and then Sam at YC. He’s advised some of the best founders through his work at YC Continuity and now his own fund First Harmonic. I love talking to Ali and always learn something new. Hope you enjoy.

Excited to share that we’ve raised a $40M Series B at @unifygtm to transform growth into a science. Many of the fastest growing companies like Cursor, Perplexity, Flock Safety and Airwallex choose Unify to reimagine growth in an AI-native world. This round comes just 9 months after announcing our Series A, and was led by Battery with participation from OpenAI, Thrive and Emergence 👇





I’m excited to announce the public launch of First Harmonic. We are a small team of former operators who invest in early-stage companies and run what I believe is the world’s best go-to-market program for seed-stage founders. We have run six cohorts of the program to date with an NPS of 100 across the nearly 50 founders who have participated. Over a long career in tech, I’ve had the privilege of working with Steve Jobs and Ed Catmull at Pixar, of taking Twitter from $0 in revenue through IPO as the CFO and COO, and of mentoring hundreds of founders at all stages in 10 years as a YC partner. I’ve also been fortunate to invest as an early angel in several breakout AI companies, including Mercor, Decagon, and Cursor. I’ve seen the arc from inception to IPO many times and recognize what separates winning startups from the pack. It's this multi-stage experience as an operator and investor that is uniquely valuable to the founders in our program. What’s this program about? A common challenge that all founders face in the early days is defining their ideal initial customer. Great go-to-market strategy begins with narrow customer selection. Every important decision is downstream of customer definition: roadmap priorities, customer acquisition strategy, sales model, pricing, etc. If you don’t define your customer well, everything else becomes extra hard. In our program, we help founders nail early customer definition through intensive 1:1 work. It’s the point of highest leverage. Our cohorts are small (10 to 12 companies), and we don’t accept applications. Instead, we select founders who have been nominated by people we trust, increasingly by alumni of our program. The program requires a 3–4 hour weekly time commitment over 8 weeks and sets startups on the right go-to-market path for life. The program will always be free and non-dilutive to founders. In order to make this possible, we’ve raised an early-stage fund that covers the costs of running the program. But there are no investment expectations or strings attached to participating. If you’re an early-stage founder, you can read more about what we believe in the link in comments. If you’re a seed investor, we hope to collaborate with you.

I’m super excited to launch what we’ve been working on quietly for quite some time now! A new, free, go to market program for founders. We are six cohorts in, with an NPS of 100 so far. It’s been so fun to run and to know that my prior experience as a founder can help others
