Firetiger Built a Watchtower for Every Deploy - Then Cursor Bought the View
A seven-person startup taught AI agents to babysit your deploys and tell you, in one word, whether the change was healthy. Two years and $7.6M later, Cursor absorbed the team to close the loop from writing code to running it.
Ido Ben-Natan
Ido Ben-Natan is the co-founder and CEO of Blockaid, a blockchain security company that protects crypto wallets, apps and users from scams and onchain exploits in real time. A veteran of Israel's Unit 8200 and the Office of the Prime Minister, where he led a cyber security R&D team and won the Israel Defense Prize, he launched Blockaid in 2022 to bring nation-state defensive expertise to Web3. The company is trusted by Coinbase, MetaMask, Kraken, Uniswap and Stellar, and has raised roughly $89 million from investors including Ribbit Capital, Sequoia, GV and Greylock.
Blockit AI
Blockit AI is a San Francisco startup building an AI scheduling agent that runs your calendar for you. You cc it on an email or ping it in Slack, and it books, reschedules, and negotiates meetings autonomously - learning which meetings are movable and which are not. When two Blockit users need to meet, their agents talk to each other directly, skipping the human back-and-forth. Founded by former Sequoia partner Kais Khimji and calendar veteran John Han, the company raised a $5M seed round led by Sequoia in January 2026 and says it has coordinated more than 100,000 meetings across 200+ companies.
Astrocade
Astrocade is an AI-powered social gaming platform that lets anyone build, remix, share and play casual games from natural-language prompts - no coding required. A coordinated team of generative AI agents handle art, sound, mechanics and UI, turning a sentence into a playable game in minutes. Co-founded by AI researchers Amir and Ali Sadeghian alongside Stanford's Fei-Fei Li, the company is backed by Sequoia, Google, NVIDIA and others.
Bunkerhill Health
Bunkerhill Health is a San Francisco AI company building the 'system of action' for hospitals. Its Carebricks platform lets health systems create, share, and deploy AI agents that turn routine data - especially CT scans already sitting in the archive - into actionable clinical findings. Born out of Stanford's Center for AI in Medicine and Imaging, the company has racked up a string of first-in-class FDA clearances for opportunistic detection of cardiovascular and bone disease, and in 2026 secured a national CMS reimbursement pathway for AI cardiovascular analysis.
Found
Found is a San Francisco-based financial technology company that bundles business banking, automated bookkeeping, and tax tools into a single platform for self-employed Americans. Founded in 2019 by ex-Square executives Lauren Myrick and Connor Dunn, Found pairs an FDIC-insured business checking account (via Lead Bank) with real-time tax estimates, automatic expense categorization, invoicing, and quarterly tax payments - aimed at the 64 million Americans who work for themselves.
Freed
Freed builds an AI medical scribe that listens to patient visits and writes clinical notes for doctors. Founded in 2022 by ex-Meta engineers Erez Druk and Andrey Bannikov, the company is used by 20,000+ clinicians and raised a $30M Series A led by Sequoia Capital in March 2025.
