very unclear if VC is a real job

After first partnering in the Series A, we're thrilled to return to co-lead the Series D for Hightouch. The best founders can continually expand and redefine their scope of impact. Thank you @kashgupta_, @tejasmanohar, @joshwget and excited about your journey ahead!

So proud to announce that @HightouchData has raised a 150M Series D, led by @GoldmanSachs and @BainCapVC, valuing the company at $2.75B!

The chaos around AI and marketing is real, but @HightouchData saw through it early. They understood something simple: AI only works in marketing when it runs on your actual data. So they built agents that research audiences, create branded content, and activate markets across platforms. That clarity has driven 100%+ growth for two straight years and led enterprises like @Dominos, @PetSmart, @DraftKings, @tryramp, and @Whoop to put it into practice. They just announced a $150M Series D at a $2.75B valuation to keep growing. Congrats to the founders @kashgupta_, @tejasmanohar, @joshwget, and the whole team on this industry-defining platform. cc: @KevinZhang wsj.com/cmo-today/gold…

Personal news: After ByteDance Seed and a stint as an independent researcher, I'm joining @fleet_ai as a Member of Technical Staff on the research team 🚀 Building Witness-inspired puzzle environments for ARC-AGI-3 convinced me that RL environments are one of the most under-explored bottlenecks on the path to truly capable agents. The team, the technical vision, and the open problems are a perfect fit. It’s exactly where I want to spend my next chapter. If you're interested in building and scaling dynamic, complex environments that push the boundaries of agentic reasoning, would love to connect.

📣 We just raised our $45M Series B from @TCVTech and @firstharmonic, with participation from @BainCapVC, @firstround, and @AlkeonCapital. Sales is the most expensive function in most companies — and one of the hardest. Hundreds of accounts, different context, different stakeholders, different dynamics, and a different path to close. No one can do that perfectly. Critical things get missed. So we gave every account its own AI agent — working 24/7, maintaining full context, progressing it through the funnel, and guiding reps and leaders on what to do next. The greatest privilege has been building alongside companies like @Samsara @tryramp @ironclad_inc and @attentiveHQ — enterprises with thousands of sellers who are already living in the future. There are only two unbounded upside problems out there: building and selling. Every company sells. and @useactively is building the system they'll all run on. We’re excited to pull every revenue team into the future we know is inevitable.

@thetysonchen @kleinerperkins @MeritechCapital @generalcatalyst @Amplify @FortuneMagazine Go Tyson!!

Today, I’m thrilled to announce Avoca has raised over $125M across Seed to Series B at a $1B valuation, backed by @kleinerperkins, @MeritechCapital, @generalcatalyst, @Amplify, and other top Silicon Valley investors to bring AI to the services economy. @FortuneMagazine Exclusive by @agarfinks fortune.com/2026/04/27/avo…

@tylertaewook @ndstudio 🫡

I joined National Design Studio as a Member of Technical Staff in D.C. AI is reshaping how people and systems interact, yet the government services millions rely on are still slow and hard to use. We’re bringing frontier technology and design to rethink these experiences end to end for the entire nation. The team @jgebbia and @as400495 has assembled is exceptional, and I’m excited to play my part. Onwards!

@brandon_wang23 that’s what my parents told me over dinner last night too

@kevinzhang it’s time to move back to new york city sir

Another flawless day at Stanford

@PraCha98 Sadly I didn’t get the best photo of it

@kevinzhang Butler lawns are glamorous!

@tylertaewook i'm sure campus misses you too! but serving your country is even more Columbia than attending🤗

@kevinzhang peak weather🩵 missing campus already

@rajeshsawhney It’s been too long! Will you be in San Francisco sometime?

@kevinzhang Let’s meet late May at Stanford.

After 7 failed ideas, Han hit “pivot hell”—a week of no sleep, staring at the ceiling, trying to make something work. Then Mintlify clicked. Today it powers docs for 20K+ companies, reaching 150M+ people and, increasingly, AI agents. ~15% of doc traffic was AI a year ago. Now it’s ~50%. Soon, maybe 90%. Docs aren’t pages anymore. They’re context. The companies that win will be the ones that manage it best. Watch the full story ↓ @handotdev @hahnbeelee @mintlify @kevinzhang

every marketer I talk to is banging their heads against a wall right now "how do I get AI ads to not be... so bad?" we just launched Ad Studio @HightouchData ✅ we know your brand ✅ we know your existing creative ✅ we know what works in your ads ps: you can edit without re-prompting

Mintlify just got valued at $500M. For a documentation company. That sounds absurd until you understand what documentation means when AI agents are the primary consumers of your API. Mintlify auto-generates llms.txt files and MCP servers for every customer's docs. That means Cursor, Claude, and ChatGPT can all ingest a company's product docs directly, without crawling HTML or burning tokens on noise. When an AI agent tries to integrate with your product and the docs are incomplete, it doesn't file a support ticket. It picks a competitor. Zero signal back to you. Documentation just became your highest-leverage sales surface, and most companies still treat it like a chore nobody wants. The customers tell you everything. Anthropic, Microsoft, Coinbase. Over 20% of recent YC batches run their docs on Mintlify. They acquired Trieve for RAG search and Helicone for LLM observability in the last year. They're assembling the full stack between "agent has a question" and "agent gets the right answer." They even ship agent analytics: which AI agents visited your docs, which pages they read, which queries they ran through MCP. That data didn't exist 18 months ago. Now it's the equivalent of seeing every autonomous system that evaluated your product and what it couldn't find. a16z and Salesforce leading at $500M is the market pricing in a bet that documentation becomes the primary interface between AI agents and every software API on the internet. The boring infrastructure layer always gets repriced last.

@handotdev @BainCapVC 🥹

people don't know this, but @kevinzhang and @BainCapVC has been there since day 0 kevin took a chance on me since I was a junior in college, inspired me to become a founder, and wrote the first check into the company we simply would not be here without him
