Crypto / Web3 Startups funded by Y Combinator (YC) in the San Francisco Bay Area 2025

Founded in June of 2012, Coinbase is a digital currency wallet and platform where merchants and consumers can transact with new digital currencies like bitcoin, ethereum, and litecoin. Our vision is to bring more innovation, efficiency, and equality of opportunity to the world by building an open financial system. Our first step on that journey is making digital currency accessible and approachable for everyone. Two principles guide our efforts. First, be the most trusted company in our domain. Second, create user-focused products that are easier and more intuitive to use.

Protocol Labs is an open-source research, development, and deployment laboratory. Our projects include IPFS, Filecoin, libp2p, and many more. We aim to make human existence orders of magnitude better through technology. Some of our projects. IPFS makes the web work peer-to-peer. IPFS is a protocol for storing, addressing, and transferring data, designed to replace HTTP in many contexts. IPFS uses content-addressing to uniquely identify and link to information. IPFS is one of the leading protocols of Web3, crypto, and the decentralized web movements. IPFS serves millions of end users and tens of thousands of developers. It powers the websites and applications of small startups, large enterprises, and even blockchains. Filecoin is a decentralized storage network, designed to store humanity's most important information. Filecoin is a cryptocurrency incentivized decentralized market, where storage providers earn filecoin tokens for renting out storage space. (Think airbnb for cloud storage). Filecoin is one of the leading projects in the cryptocurrency/blockchain space.

Listia is a new kind of auction marketplace for giving and getting free stuff. Users list items as auctions, and other users bid on these items using credits instead of money. Credits are earned by signing up, giving away stuff, and being an active member.

Paymobil is a global bank account replacement using stablecoins. We make it possible to send money to any email or phone number in the world in seconds. We have taken all the friction out of the current terrible UX with crypto p2p payments and made it better than regular consumer products like Venmo and Square Cash. Unlike those it works across borders and can launch globally due to our non-custodial architecture.

Filta is the face filter NFT marketplace being built by veterans from Pixar/Oculus/Facebook. We partner with creators to release limited-edition filters for their fans to use on social media. It turns out: the face filters you see everywhere on Snapchat and Instagram are created by independent artists - not by the platforms. These artists ALMOST NEVER get money for their work - which is insane! Filta fixes this by giving these creators a marketplace and the best filter creation tool anywhere. Interested in working on the future of digital fashion, AR/VR, and web3? Hit us up. We're hiring.

Satsuma is a developer tool for building applications on top of real-time blockchain data. Our product lets developers take decoded data from multiple chains, customize it for their use cases, and access it through API endpoints. Blockchains serve as distributed databases for these products, holding their most important data. However, it’s difficult to access and query that data. We believe this friction is an enormous blocker for web3 developers and that better tooling will enable mass adoption for web3. We’re a founding team of engineers, having built data infrastructure and product as early employees at Airtable, Heap, and Y Combinator.
