Firecrawl began as a fix for its founders' own chatbot. Now it wants to be the library card for AI agents - and to pay some of the people who stock the shelves.
Dapper taught websites to give up their data, then made that data work inside ads. A frozen funding round nearly stopped the experiment; Yahoo bought the result.
Browserbase gives software agents real cloud browsers, then handles the messy parts: logins, broken pages, bot defenses, and proof of what happened. Its customers are discovering that the most useful AI task may be the one hiding in an ordinary website.

Bardeen can turn a messy hunt across tabs into a tidy lead list. The clever bit is where it works - inside the browser - and that is also where buyers should look closely before handing over the keys.
Sequentum spent 18 years making web extraction boring enough for banks, governments and large companies. Now it is using AI to build agents quickly - while refusing to let AI guess when the production run begins.
What began as proxy infrastructure now sells something AI agents urgently need: live public web data that arrives structured, usable and less likely to break at the first CAPTCHA.
Yoeven Khemlani is the CEO and co-founder of Interfaze, a Y Combinator-backed AI company building a purpose-built model for deterministic developer tasks like OCR, web scraping, classification and speech-to-text. A second-time founder, he previously built JigsawStack, a suite of small, custom AI models for backend engineering, and before that was CTO and co-founder of the Southeast Asian prop-tech startup Stayr/Staytion, which he scaled and exited. A former game developer and edge computer-vision researcher, he moved from Singapore to the San Francisco Bay Area to build AI infrastructure that prizes reliability over raw intelligence.
Interfaze is a San Francisco AI startup building a model purpose-built for deterministic developer tasks - OCR, web scraping, speech-to-text, object detection and classification - where consistency and verifiable output matter more than open-ended chat. Its hybrid architecture fuses specialized neural networks (CNN/DNN) directly into a transformer decoder, and the model ships as an OpenAI-compatible API with confidence scores, bounding boxes and metadata so developers can build rule-based systems on top. Founded by Yoeven Khemlani and Harsha Vardhan Khurdula, Interfaze is part of Y Combinator's 2026 batch and grew out of the team's earlier developer-API company, JigsawStack.
Reprompt builds AI agents for location data. Mapping companies like Foursquare, TomTom, and Radar use its agents to keep points-of-interest and business records current - verifying hours, status, ownership, and dozens of other attributes by cross-referencing web, social, government, and news sources. Founded in 2024 by ex-Mapbox and ex-Robinhood operators, the company turns work that once took weeks of manual research into runs that finish in under an hour.
The Hog is a San Francisco startup from Y Combinator's Fall 2025 batch that packages people data, company data, web search, news, social signals, sentiment, and scraping behind a single pay-per-call API for AI agents and go-to-market teams. It routes each request through multiple data providers using waterfall logic, positioning itself as one endpoint that replaces a stack of tools like Clay, Apollo, Exa, and Tavily. Founded by growth operator Hudson Liao and AI engineer Paulo Nascimento, it aims to compress market research and outreach from hours into minutes.
Diffbot is an AI company building one of the world's largest knowledge graphs by autonomously crawling, reading, and structuring the public web. Its APIs and LLM turn unstructured pages into machine-readable facts about people, organizations, products, and articles - powering search, sales intelligence, market research, and grounded generative AI.

Orange Slice AI (YC S25) is an AI-powered sales intelligence platform that uses real-time web signals to find high-intent prospects for B2B sales teams. Co-founded by Kishan Sripada and Vihaar Nandigala — who met on a Bollywood dance team at the University of Michigan — the platform lets sales teams generate targeted lead lists using plain English, enrich existing lists with live data, detect niche buying signals before competitors, and manage pipelines through conversation. Backed by $5.3M in seed funding co-led by 1984 Ventures and Moxxie Ventures, with Paul Graham as an angel investor, Orange Slice has attracted 5,000+ sales and RevOps teams including Oracle, Confido Health, Pirros, and Glass Health.
