Matthew Rossi

@vcastellm Welcome to the team!

Hey everyone, I have some news to share: Four years ago I joined Polygon, coming off a long tenure at Jobandtalent where I worked with one of the best engineering teams in Spain. I grew a lot there scaling systems and databases to millions of users and bringing Web 2 best practices into a fast-moving company. Then I wanted to go deeper into distributed infrastructure and brought that experience into the Web3 ecosystem at Polygon. Over time I got into protocol internals and client development. The most rewarding chapter of my career so far. As you may know, everything comes to an end. Back in mid-January, there were layoffs at Polygon x.com/vcastellm/stat…. I took some time to reflect on what I actually wanted to do next. My timeline has been on fire since the releases of Claude Opus 4.5 and Codex 5.3, no surprise, since I’d been delivering features at Polygon without writing any code since November. The intersection of AI and infrastructure had been pulling at me. Then came the right timing. Matthew Rossi, a friend and former colleague at Polygon, reached out. His team had built something interesting, and uncovered an even more interesting problem underneath it. This is why I am genuinely excited to announce that I am joining Matthew and Katara AI as technical co-founder. At Katara AI katara.ai, we are building compliance-native RAG infrastructure for enterprises in regulated industries. The specific problem: most AI infrastructure was built for speed, not for the governance questions that arrive after deployment, what data entered the system, where it went, who had access, and whether you can prove it to an examiner. AI adoption in financial services, legal, and healthcare is moving faster than the infrastructure those industries actually need. That gap is worth fixing. I am not leaving the Web3 world entirely, I will continue advising projects I believe in. But this problem is too important and too well-timed to ignore. We will be building in the open. Follow along as we navigate what it actually takes to build compliance infrastructure for the AI era. If you are working on enterprise AI deployment, regulated infrastructure, or just want to follow the journey, my DMs are open.

We are! Wanna meet up? Katara co-founder @MatthewRossi will be onsite April 8-10th!

@Fetch_ai Nice, we will give it a try over at @KataraAI ;-)

Big News! You can now stake your MOR and unlock full access to the Katara AI platform!

We are super excited about our new partnership with @partisiampc - a lot more to come here soon but privacy preserving agentic workflow automation sounds awesome to us - even if that is a mouthful! LFG 🚀

2-3 years of public availability and already the AI is earning an increasing % of societies mind-share My interview with @MatthewRossi from @KataraAi explores what this means and how we can grow from it

@FitFounder Moved from NYC to Barcelona

What improved your quality of life so much you wish you did it sooner?

@mathboulianne @josephdelong Hola @josephdelong - building from Eixample - hit my DM?

Are there any degenerates in Barcelona?

@ChainCrusader @ai @KataraAi Thanks for the tag @ChainCrusader - we should review that SAGA backtest no? 😁😊

@ai I know @MatthewRossi is trying to solve this with @KataraAi

Lazy ask: Discord servers are such treasure troves of info. Are there LLM based chatbots that server owners (or users) can enable to have context aware conversations?

@ai Hi @ai - we're working on something similar at @KataraAi - totally agree - so much good info is lost on Discord - not a "chatbot" tho - more like a RAGaaS human-in-the-loop content improvement platform - but understanding/responding to community/audience Q&A is a required step

Awesome! Thanks @AvailProject !!

App Specific Rollups leads to App specific Block explorers Heck, App Explorers! Massive design change will come to how we use block explorers. It will not just about seeing blocks, it will be about what the blocks mean. I have some ideas, will share soon.

Uber has no cars Airbnb has no homes OpenAI has no employees this is the new economy

@benfielding @gensynai @POKTnetwork

The platform risk with these AI APIs is insane - we need a decentralised alternative We're building the resource level @gensynai (compute) but who is building the application level?

@jdkanani @RollkitDev on @CelestiaOrg - already happening, we’re building now for @POKTnetwork 😜

Prediction: All DA projects will build Rollups and try to eat L2 pie.

Infura using pokt now. Nice
