From San Francisco: here's everyone we talked to at Y Combinator Demo Day. Starting with our exclusive full interview with Garry Tan, President and CEO of YC.

We talked to @aquariusacquah and @michaelssilver, the co-founders of @joinkaizen. Kaizen leverages browser agents to enable instant integration into websites without APIs - it "helps computers use computers."

We caught up with @yonasbe and @dbworku from @starslingdev, building Cursor for DevOps. Its agentic developer homepage automates all the tasks that eat up a developer’s time after they’ve left their code editor (deployments, performance, incidents, and bugs).

We got to know @marco_dewey and Mateo Perez, the co-founders of @Jazzberry_ai. Jazzberry is training LLMs to be expert bug finders. "It's time to close the loop on vibe coding." - they told us.

We met @eddieconkml and @endorseurgirl from @cotoolai, building composable AI agents for security teams. Their co-pilot aims to give time back to cybersecurity teams.

We spoke to @EricMao06 and @toomzheng. They are working on @cladoai, which is deep research for people. It puts 200M+ people profiles (and growing) at your fingertips with simple, agentic search.

We talked to @AaronLCannon from Outset, focused on AI-powered user interviews. Outset uses LLMs to lead interviews and synthesize results, so that researchers get high quality data 100x faster.

We got to know @never_settles_ and @erikqu_ working on @operative_sh. Operative does web application code generation for internal APIs. "You can think of it like Retool, except instead of external integrations, we connect into an org’s internal BE, and use AI to generate the FE code."

We saw @m_franceschetti, CEO of @eightsleep, a hall of fame TBPN sponsor. Matteo told us about his new collab with Formula 1 driver Charles Leclerc to develop cooling gloves. He also shared that he invests in approx. 20% of each YC batch to support tech innovation.

We talked to @arnauaye and Pablo, the co-founders of @ThroxyAI. They are developing vertical AI agents that book meetings for companies selling into traditional industries like manufacturing, logistics, education and finance. By running the sales funnel on autopilot, they want to take over your outbound, so you can run your business.

We spoke to @Adityav369 and @ArnavAgrawal03 from @morphik_ai. Morphik offers open-source multimodal search for AI apps. They are used by customers ranging from space-tech teams searching across research papers to developers building brokerage agents.

We saw @hemangkandwal and @anguel_hh, who are building @ClideyOfficial. Clidey makes documentation for AI agents. Their goal is to save 30% of employee time by auto-generating documentation from onboarding guides to API references and system diagrams.

We talked to @trycua, docker for computer-use agents. @francedot and @pupposandro are working on an open-source framework that enables AI agents to control full OS within high-performance, lightweight virtual containers. Currently, it delivers up to 90% native speed on Apple Silicon and works with any language models.

We caught up with friend of the show @zebulgar. He reflected on his experience with YC's Summer 2014 batch, the challenges of raising a seed round for his startup Nightingale, and the evolution of Demo Day.

We talked to @davemuni from @GVteam. He explained the transformation of YC from its early days in Cambridge to its current status as a 'startup machine'. We also talked about GV's investment approach, from seed to public markets.

We spoke with @ndrewlee from @a16z. We asked him to break down the role of AI in entertainment, his thesis on the "AI Pixar" moment, and the challenges in game distribution.

We met @shreyash_nm, who's building @ChonkieAI. Chonkie breaks down large documents into smaller, meaningful chunks, making it easier for AI to process information.

We got to know Cinnamon and Abhijit from Godela. Godela is an AI physics engine to replace simulations and prototypes. It brings AI-powered intel to the physical world, and lets engineers run experiments faster and cheaper.

<Thread break> more startups coming up...

We talked to @Justin01805921 and Linus from @supportingden. Den is Cursor for knowledge workers. "We want to deploy trillions of AI agents into the mainstream workforce and unlock the most productive era in human history." - they told us.

We met @TugceBulut and @AldoLipani, working on @EloqAI. Eloquent is the AI operator for financial services. Their AI operator learns by observing existing workflows and SOPs, securely controlling browser and desktop applications to automate up to 96% of tasks.

We spoke to @1davidyu1 and @achyut_benz. They are working on @youlearnai, which gives an AI tutor to each student. Their product turns learning materials into concise notes, an AI tutor you students can talk to, and personalized tests.

We talked to the founding team of @blaxelAI. They maxed out our cameras, which is a first! Blaxel is AWS for AI Agents. Their platform gives AI companies the toolbox and infrastructure to build and deploy agents efficiently.

We spoke to @mxshra and Diogo, the co-founders of @waffledotai. Waffle is the AI operating system for SMBs. Their users include travel agents, fitness instructors, and personal tutors. "We’re targeting $200B+ in annual spend by US SMBs on their customer acquisition tech stack." - they told us.

We met the @VibeGrade founders. @coderpr0grammer and @aql404 are building Cursor for teachers. VibeGrade works directly inside Google Classroom, Google Docs, and Canvas to grade papers 10x faster, in the teacher's style.

We talked to @bryanguin and @cornelius_schra from @AvallonAI. Avallon provides AI agents for insurance claims operations. These agents help handle routine calls and documents processing.

We met @irushishah, @parasmaniar and @PraharPatel55 working on @textdotai. "You can now text AI in your existing chats." - they told us. No downloads needed. No learning curve, just text and go.

We talked to Anir and Pietro from ValueMate. They are automating real estate appraisals with AI, and hoping to transform the multi-billion dollar appraisal industry with tech that captures millions of 3D data points per walkthrough.

We met @itsdavidalonso and @sirian_m from @CreateWithBloom, which allows people to build and share mobile apps in seconds. Their product lets you vibe code cross-platform apps and test them on your phone natively. It deploys a backend for you, so you can build functional MVPs and personal apps, not just toys.

We spoke to Ayna and Andrew from MorphoAI. They are building a software tool for designing robots and machines. "We allow users to invent and modify machine designs in a matter of minutes, not years." - they told us.

We met @RajitWrites, @spicy_liu and @LTantichot, the founding team of @teamprismai. Prism is "AI-native Datadog + Amplitude". It watches your session replays and tells you what to fix.
