We're excited to announce that Christopher Golda and Grey Baker are joining Y Combinator as General Partners.

Chris and Grey have both been Visiting Partners at YC, where they've already made a big impact working closely with founders across multiple batches. Now, as General Partners, they'll play an even bigger role in selecting, advising, and supporting the companies we back.

Chris co-founded BackType (YC S08), a data infrastructure and analytics company acquired by Twitter in 2011. At Twitter, he launched and ran the Ad Center product, growing revenue to over $1B. Since leaving Twitter, he's been working directly with founders to help them find customers and raise capital, participating in early-stage rounds of companies like Benchling, Coinbase, Stoke, and Supabase. As a Visiting Partner, he's brought that combination of deep technical founder experience and a decade of pattern-matching across hundreds of early-stage companies to the founders he works with.

Grey co-founded Dependabot, a developer tool used by over a million people that was acquired by GitHub in 2019. Before that, he was an early employee at GoCardless (YC S11), joining when it was just six people and leading product and engineering as the company grew to over 100. After GoCardless, Grey cycled 29,000 km around the world, then came back and built Dependabot as a side project that took on a life of its own. He went on to co-found Pincites (YC S23), which was acquired by Filevine. As a Visiting Partner, he's brought a builder's mentality and firsthand experience scaling products from side project to millions of users to every batch he's been part of.

As General Partners, Chris and Grey will work directly with YC founders at every stage of their companies. We're super excited to have them on the team. Welcome, Chris and Grey!

We're thrilled to announce that Diana Hu has been promoted to Managing Partner at Y Combinator.

Diana first came through YC as a founder. She co-founded Escher Reality (S17), an augmented reality backend that was acquired by Niantic in 2018. Diana returned to YC in 2021 as a Visiting Group Partner, and joined full-time as a Group Partner in 2022. Over the past four years, she's become one of the most prolific partners in YC's history. She's worked with nearly 230 companies across 18 batches, logged over 2,100 office hours, and those companies are now worth a combined $7 billion.

Diana grew up in Chile and studied computer vision and machine learning at Carnegie Mellon. She built her technical foundation early: data science at OnCue before Verizon bought it, ML research at Intel Labs, then Escher Reality as CTO. At Niantic, she ran the AR Platform team and shipped AR to the 100M+ people playing Pokémon GO.

Few people have both built a startup from zero and shipped tech at that scale. Diana has done both. That combination, paired with deep technical experience in ML and AR, is exactly what today's founders need from a partner. Diana has been at the center of working with the builders pushing the frontier on AI, robotics, and hard tech, including breakouts like Avoca, Reducto, David AI, Salient, Stepful, and HappyRobot.

Congrats, Diana. We're lucky to have you.

We're thrilled to announce that Harshita Arora is joining Y Combinator as a General Partner.

Harshita has been a Visiting Partner at YC since the Summer 2025 batch, making her the youngest visiting partner in YC's history.

Harshita discovered coding at 13, dropped out of school at 15 to pursue it full-time, and by 16 had built Crypto Price Tracker, a crypto portfolio management app that was featured by Apple, which was subsequently acquired, and earned her India's Bal Shakti Puraskar, one of the country's highest honors for young achievers. She then received an O-1 visa, moved to San Francisco, and co-founded AtoB (YC S20).

Harshita and her co-founder came into YC with an idea that got killed by Covid, and with zero background in trucking or payments, they spent weeks visiting truck stops until they found the idea that would become AtoB. Today, AtoB is a Series-C stage company building financial infrastructure for the trucking industry. Often described as "Stripe for Trucking," it offers fleet cards, instant payouts, and modern financial tools, serving over 30,000 fleets across the US.

As a General Partner, Harshita will work directly with YC founders at every stage of their companies. She brings deep fintech and infrastructure experience, a founder's instinct for product, and the perspective of someone who's been building companies since she was a teenager.

We're super excited to have her on the team. Welcome, Harshita!

Going forward, YC will once again invest in US, Canada, Cayman, and Singapore corporations.

We previously decided to remove Canada from this list because we noticed that our top-performing Canadian companies reincorporated in the US. This is likely because incorporating in the US gives companies easier access to investor capital at Demo Day. But we don’t want to suggest that we no longer fund Canadian startups or Canadian founders. In fact, we invest in dozens of Canadian startups each year and have hundreds of Canadian founders in our alumni network, including one of YC’s founders, Trevor Blackwell.

If you’re a Canadian founder, we welcome you to apply to YC.
