Excited to announce @firecrawl's $14.5M Series A 🔥 We've grown 15x in the past 12 months. The demand for clean web data in AI is real. Here's the story of how we built the web data layer for AI - starting from a side project to powering how 350k+ builders get web data 🧵

no shade but why would superintelligence need an office suite?
We made the best agent-native office suite. It’s free, collaborative, and more precise than other tools for docx, pptx, and xlsx editing. Available today in ChatGPT and Codex. More below.

It also assumes the game isn't iterative Defense hardens over time as exploits are discovered
About damn time. Attackers do not hold the advantage forever. This will be a rough transitional period where Elden Software, crafted by faulty human minds, dies out. After that, a very different era begins.

"Lets train our AI's to work just like all the companies that failed and sold for parts" seems like adverse selection
such an interesting launch. couple of thoughts on two themes I’m seeing in the market rn: 1/ there are so many companies like Replay and Micro1 trying to purchase proprietary data from wound-down companies. That data can then be used to improve performance at the model level, leaving us with a very smart large model doing more of your work end to end and working like a true colleague 2/ we're going to see a wave of agentic workflows 2.0 like this one from Hone where they understand that slack-agent workers like Tomo/Viktor won't cut it and you need to train your agents on outcomes asap. This is what Instict is doing for personal AI, basically going after persistence and the agent learning what you want and taking you out of the loop essentially. Hone is directionally right on doing the same for your business The game at play is that they're all trying to build a rockstar worker: Someone who'll never ask for the same thing twice and they’ll be proactive about what they don’t know or need confirmation on. It's generally trivial to spec that out to an agentic employee, but it’s been historically hard to build a UX that enables it end to end, without much coordination overhead, while also building trust with a human on it's competence lot's of data + UX/UI + training innovation will happen in this space and I'm so giddy about the next stage

We're using a swarm of agents to catalog the internet. We're calling it Alexandria. It's live today Search boxes were shaped around human limits. Models are smart enough to navigate a catalog. They don't need a new Google. They need a library nitter.cf/firecrawl/status/21024…
Introducing Alexandria. We raised a $75M Series B led by Smash Capital to build the world’s largest knowledge library for superintelligence. Supercharge your agents with instant access to the most powerful data sets & providers. firecrawl.dev/alexandria

Your coding agents need the best knowledge
Coding agents rely heavily on search tools to find the answers they need. But which tools actually help them find the right sources? Today we're open sourcing DevDex, a benchmark for how reliably search tools find what a coding agent is looking for. firecrawl.dev/benchmarks/dev…
