Introducing TigerFS - a filesystem backed by PostgreSQL, and a filesystem interface to PostgreSQL. Idea is simple: Agents don't need fancy APIs or SDKs, they love the file system. ls, cat, find, grep. Pipelined UNIX tools. So let’s make files transactional and concurrent by backing them with a real database. There are two ways to use it: File-first: Write markdown, organize into directories. Writes are atomic, everything is auto-versioned. Any tool that works with files -- Claude Code, Cursor, grep, emacs -- just works. Multi-agent task coordination is just mv'ing files between todo/doing/done directories. Data-first: Mount any Postgres database and explore it with Unix tools. For large databases, chain filters into paths that push down to SQL: .by/customer_id/123/.order/created_at/.last/10/.export/json. Bulk import/export, no SQL needed, and ships with Claude Code skills. Every file is a real PostgreSQL row. Multiple agents and humans read and write concurrently with full ACID guarantees. The filesystem /is/ the API. Mounts via FUSE on Linux and NFS on macOS, no extra dependencies. Point it at an existing Postgres database, or spin up a free one on Tiger Cloud or Ghost. I built this mostly for agent workflows, but curious what else people would use it for. It's early but the core is solid. Feedback welcome. tigerfs.io

A week from today, we will be at Anthropic, OpenAI, and xAI, demanding that leaders agree to a conditional AI pause. These companies are recklessly endangering all of our lives. Their excuse is that they can't pause unilaterally. So they must commit to pausing if others do.


It’s a great time to build something new! For the next two weeks, we’re doubling rate limits on weekends and outside 5-11am PT on weekdays


I quit my executive job to live the AI-native startup life. And I've spent years studying what it takes to shift an existing team to a new way of working. In my experience, it takes 3 things: - a new operating model - technical readiness (prepare the repos!) - cultural change I'm SO psyched to be kicking of this very limited @MavenHQ weekend course (April 18-19) for EPD executives and super senior ICs with my friend Zach at LaunchDarkly, a Principal Engineer that went from AI-skeptic to the AI-champion in our team. This is NOT for - ICs looking to learn things like claude code - people wanting high level consulting fluff - small teams who are already yoloing the tokens This IS for - VP+ executives in product, engineering, and design - staff + engineers - 100+ person teams who need to move AI mountains @gaganbiyani has been asking me to put something together for several years, and I said I would only do it if it was something I really thought I could uniquely speak to, was technical, and focused at my peers. This is that. I'm also excited we'll have @chintanturakhia and @thenanyu as guest speakers to talk about what they're seeing and doing as EPD leaders. We just opened enrollment, and recommend you register as an exec-sr. IC pair to get the most out of the content: maven.com/clairevo/ai-na…
