Dari
Dari (YC F25) is a San Francisco startup building an API for reliable browser-use agents. Instead of calling an LLM on every run - which makes most browser agents slow, expensive, and non-deterministic - Dari learns a web workflow once, then caches the deterministic DOM steps so it can replay them reliably. It auto-handles 2FA (SMS codes, TOTP, email verification), detects when a site changes and adapts with AI, and exposes each automation as a versioned, stateful API endpoint. Founded by Caltech CS grads Avyay Varadarajan and Benjamin Hong.
Kernel
Kernel is a San Francisco startup building browser infrastructure for AI agents and web automations. Its cloud browsers launch in a few hundred milliseconds, persist login state across workflows, and evade bot detection, letting developers point agents at the live web without operating their own browser fleet. Backed by Accel and Y Combinator, Kernel raised $22M and says it is used by thousands of teams building agents, including Cash App and Rye.
TinyFish
TinyFish is a Palo Alto-based enterprise infrastructure company building web agents that let AI reliably navigate and act on the live web at scale. Its agents log in, fill forms, extract structured data, and complete multi-step workflows across thousands of sites at once - handling tasks like real-time hotel inventory aggregation, competitive price monitoring, and market intelligence. Founded in 2024 by Sudheesh Nair, Shuhao Zhang, and Keith Zhai, the company launched publicly in August 2025 with a $47M Series A led by ICONIQ, and counts Google, DoorDash, and Fortune 500 brands among its customers.
