Building the social network layer for AI apps - starting with college. Co-Founder of A1Zap (YC W25)💬, Forage (YC W19 - Acquired)

PSA: On a @Waymo through Portero Hill - just had two black matte cars block me in the middle of the road, flash custom beam lights into and start aggressively drive towards it. Felt co-ordinated. Stay safe SF.

Here we go again 🚀! Excited to announce that we're building @a1baseapi (YC W25) with @pennepastaa and that we're in the @ycombinator W25 batch in San Francisco! What is A1Base? A1Base gives AI Agents a real world identity for work. We do that by rebuilding Twilio and Okta from the ground up, putting AI Agents first. This means developers can make AI-first agentic applications 10x easier with our API's. ⁉️ Why are we doing this? Because there's a huge torrent of new valuable companies possible with AI agents, but to get their AI Agents to users, they have to chain custom apps, chat interfaces, awkward Slack integrations, browser bots, and wrestle with Twilio’s legacy API (which is built for marketing). We solve this by providing developers with an easy to use API to interface your AI agent with humans/coworkers/users where they are in this case in Whatsapp, Slack, Teams, SMS and more) - with AI Agent features built in. These digital workers are poised to transform how we work and we're the critical infrastructure to help them interact naturally in human workflows. We're not just building another AI tool. We're creating the infrastructure that will enable AI agents to become a natural part of the workforce - handling everything from customer support to sales development to creative work. We're backed by Y Combinator and working with founding teams who share our vision. We believe that in the near future, AI Agents with human coworkers will enable us to pursue more creative and impactful work. Our mission is to help developers build AI Agents that people can partner with and rely on as trusted allies—always with a human-first mindset. If you're thinking about the Agentic future of your company reach out! If you're looking to build your first AI Agentic company - reach out too - we have some amazing open source templates to get you started on the journey. Excited to share more of what we're up to soon 🔜.

We just built A1Mail - email for AI agents. Turns out the problem wasn't making AI smarter, it was making them communicate like humans. Your executive assistant AI can now have its own inbox and respond like a team member. The early use cases from developers are pretty wild. Sometimes the most transformative tech solves the most mundane problems everyone assumes someone else will handle. Check out @a1baseapi today!

In the coming weeks, @pennepastaa and I are sharing lively discussions with founders we love, who are building in AI. First, I spoke with my friend @andrewyan200 from @getathenahq (@ycombinator W25), who helps brands shine in generative AI search results. We explored a striking shift in customer discovery. For the first time, a customer found A1Base through an AI chat, not a traditional search engine. This trend is gaining momentum. Andrew revealed that late last year, when ChatGPT tapped fresher data, product discovery transformed. People now ask AI systems, "Which corporate card should I choose?" instead of turning to Google. We faced a tough truth: earning a spot in AI search results isn't easy. To stand out, brands must craft precise content that answers specific prompts and publish it where AI systems look. After years of mastering Google's algorithms, we now confront a fresh challenge: staying discoverable. Those who embrace this shift and adapt will keep connecting with customers as behaviours change. How has AI search reshaped the way people find your products?

Do it! Astonishingly YC W25 is a better accelerator than W19. One underrated thing about @ycombinator is that they keep improving their product for the best founders. There’s no better place to get your company off the ground in the world, by a country mile. Apply to YC now!
The deadline for applying to YC's Spring 2025 batch is two days from now. If this batch is like most batches, some of the companies that end up doing the best will only decide to apply between now and the deadline...

I can't believe the day has come when we announce @theforage_ has agreed to be acquired by @EAB ! Forage's first-of-its-kind job simulations, millions of students, a network of universities of thousands, and it's hundreds of top employers around the world will help make EAB an unstoppable force in its mission to make education smarter and our communities stronger. When I wrote up the code that invented the first virtual job simulation (we called them virtual internships back then), we couldn't have imagined the reach, impact and success we'd have. Who knew you could make a dent in large chunks of hiring cohorts, diversity outcomes, and impact so many personal lives with technology? It's exciting to be able to prove out that you're able to help people, do something unique and make a great business. This journey has been crazy, and it hasn't been an easy or free ride getting here - but we wouldn't have gotten here without the fantastic team we've had - from exceptional engineers, product people, growth and marketing, to sales and more - with too many names and stories to share in this one post at the moment - thank you. Of course, thank you, my cofounder, @BrunskillTom , for driving this process and carrying this all through the last 7 to 8 years. The future of @theforage_ is bright, and we are excited to see it move forward with @EAB ! eab.com/about/newsroom/press…

At @a1baseapi, we’ve learned what most founders miss about AI agents: they don’t replace your team. They fix gaps. The best companies don’t automate everything. They target specific problems—meeting summaries, dashboard monitoring, support ticket routing. Tasks that waste your team’s time. The key is integration. If your AI is stuck in a separate tool, your team won’t use it. It works when it’s seamless—sending a Slack message to a specialist when a complex ticket arrives or texting a field tech without requiring a separate login. We see this in every industry: automate high-volume, simple tasks and keep human communication easy for everything else. That’s why we built A1Base. We create the communication layer that makes AI agents useful, not abandoned. Smart companies treat AI agents like team members, giving them digital identities that work across platforms, hold context, and build trust. Ready to make your AI agents effective communicators?

Building @a1baseapi has been humbling. Every week we uncover more things that are broken in the AI agent space. We started thinking "help agents communicate with people = more stuff gets done." Turns out there's way more to fix. My mate told me last night he tried ChatGPT last year and "it wasn't that good." Most people still haven't touched this stuff while we're busy building the future of AI workers. The gap between what we're building and what people actually use is massive. That's the real problem to solve. Full thoughts in the video!

How are we building @a1baseapi (@ycombinator) for the future of AI Agents? We went on the @Sachin_and_Adam Show recently to talk about our thesis of what we think the world of agents is going to look like. One thing that struck me during our chat: we're not building another chatbot interface. We're going Twilio-level deep – letting AI agents communicate where humans actually are. SMS, WhatsApp, Slack, email. Here's my take: AI isn't going to change how people work. We need to build AI around how people currently work. Find the full episode in the comments!

Culture and myths precede economic outcomes - and YC sets you up right there. The capital and technicals you see at YC is then fuel on the fire.
went through YC (and a few other accelerators) — and can genuinely say the biggest value wasn’t just the capital or demo day. it was the urgency, the belief reset, and the caliber of people you're suddenly surrounded by. not for everyone, but absolutely life-changing if you’re trying to build a unicorn.
