Met so many folks in person for the first time while streaming with the crew. Cracked me up seeing @kdy1dev play the role of an intern and @swalker326 being "Professor Shane". Meanwhile I was just trippin in the matrix with my Apple Vision Pro in the background

@freddiev4 @bhalligan Points well taken. I'm a relative newcomer to the ecosystem. I’ve seen lots of interesting, highly curated one-off events, but not as many recurring, high-profile ones. That said, I’m consistently meeting great founders here. Happy to chat more anytime.

@bhalligan @wnlehmann AFAIK there aren’t any good ones that are well known (I’ve heard mixed reviews from what are currently the big meetups) — what I’ve been seeing is lots of smaller niche meetups, but it’s been very much word of mouth

I’m starting to worry about Massachusetts 1. Biotech is way off from a few years ago 2. Only 1 of the top 50 ai companies are in MA 3. The Fed research funding cuts hitting MIT, Harvard, Whoi are brutal. 4. The millionaires tax is working in the short run, but I know a lot of wealthy folks preparing for a FL move. 5. A glut of empty condos 6. It’s not “cool” for young folks 7. It’s expensive as sh-t. I honestly don’t think the MA/Boston govt can do that much about it as they are kind of macro issues. I give them big credit for working on building more housing and fixing the T, which will help. I’m trying to help w HubSpot, partnering w WHOI, teaching at MIT. I’d like to help more. Specifically I’d like to encourage and help more ai and climate companies in the state. I think ai and climate should be our dual growth engines.

We connected everything. Now we have to keep it in sync. I wrote about why Sync is becoming the backbone of modern software — and what that means for the AI & edge era. Join me at syncconf.dev on Wednesday! inlehmannsterms.substack.com/p/we-are-all-s…

@julianeagu the takes were 🌶️ and your demo was 🔥

AI agents are the security threat of the century: they already execute billions of actions per day, often with near-untethered access to the web, data, and APIs. In adversarial tests, it only takes tens of queries before many agents start going off-prompt, violating policy, or calling the wrong tool. Maybe that's why I ended up at a security demo night tonight. We went over practical examples for how to: - monitor agents for 🌶️ issues - catch 🌶️🌶️ issues with in-the-loop evaluation - block 🌶️🌶️🌶️ issues with guardrails or evaluator hooks tl;dr how to balance risk, cost, and user experience in real-world AI systems

I wrote this because the evals debate feels stuck in abstractions and theory. Here’s what it actually looked like inside GitHub Copilot, what worked, what didn’t, and what we learned building evals in the wild after that with @QuotientAI. Lessons learned and unrequested advice if you are building an AI product today.

Sync engines, local-first, agentic UIs...the stack of the future is coming together fast. Excited to learn from the best minds in the space and join the conversation at @SyncConf in SF this autumn!

today we're releasing a new small model (0.5B) for detecting problems with tool usage in agents, trained on 50M tokens from publicly available MCP server tools it's great at picking up on tool accuracy issues and outperforms larger models

It has been a privilege to partner with the entire @AirsideHQ team since participating in their seed round many years ago. Incredible to welcome @amena_onweb to the team, announce this fundraise, and continue working with @AirsideInsider on building a better digital identity.

"We see the groundswell here happening for years, and this is only going to become more and more important." - @wnlehmann on the "massive opportunity" for open source developer security. Grateful to have written the first check in @getfossa and to support its incredible growth.

"Cryptocurrency as an asset class will not fully develop until institutional investors get off the sidelines and into the game...what these investors want is a centralized, trusted venue for trading these new currencies." @salil for @FortuneLedger #Crypto fortune.com/2018/09/12/cry…

Candid take from @salil on @nutanix acquiring @frame. Congratulations @widerlens on a fantastic outcome. Really enjoyed working with you and the entire Frame team.

@HurlinghamUK Dear Hurlingham, please remind me the email address to send member’s pictures to? My father caught a few choice pictures of the swans and cygnet today he would like to share with the club. Many thanks.

Well done @checkwarner and team at @diversityvc!! twitter.com/diversityvc/st…
