Hello World 👋 Ultra Security is out of stealth with $10M in seed funding to secure autonomous systems. Ultra puts enforceable boundaries around autonomous systems without slowing down the work they're built to do. We've built guardrails, governance, observability, and anomaly detection in one platform. Agents aren't predictable. Security should be.

1/ Today we’re unveiling Bombadil, @electricplantco's foundation model that reads the electrical signals of living plants and turns them into a continuous view of their physiology. Trained on 7M+ hours of plant electrical signal across 125+ species. That makes Bombadil the most species-diverse model of directly recorded electrical biosignals in existence. The animal equivalent would be one model that reads the brainwaves of blue whales, horseshoe crabs and fruit flies.

Finally found the login for the Carpool channel. We’re back! Andddd… we’re announcing Fund 6.

Such a fun conversation with long time friend @jaykapoor. Thanks for having me!!

Clawdbot is a live case study of what happens when agents meet our current security stack. Exposed instances. Prompt injection via email. Credential leaks. One-click RCE. 170k+ stars, massively viral, and a security model that can't keep up.

@dualentry has raised a $90M Series A from @lightspeedvp, @khoslaventures and @GVteam, bringing our total funding to $100M to date. 18 months ago, we decided to build the ERP that makes sense for today. AI already changed Sales, Engineering, and Legal. With DualEntry, CFOs finally have the modern ERP they deserve. In the last 18 months we’ve: - shipped 350+ features - processed $100B+ worth of journal entries with AI - saved businesses 1000s of hours on implementation - onboarded 1000s of users across all continents - built the world’s most powerful migration engine for a 24-hour ERP implementation Our customers range from high-growth startups to NYSE-listed companies. They close the same day, report in real time, and achieve more with leaner teams. Since switching to DualEntry, one of our customers can run $140M ARR with just 1 controller. Excited to keep building the ERP for the AI age 🚀 Retweet + comment “free migration” and I’ll send over all you need to go live in 24 hours with NextDay Migration.

We’re launching Nash next week, but I’m too excited to not share this now. There are new MCPs popping up every day and entire directories just to keep track of them. I just wanted one MCP that ties all my apps, files, and APIs together. So we built Nash (@nash_app). It has no constraints and can access any API, app, file, etc. It’s awesome. Check out the demo video below. DM or reply for the download link.

I’m thrilled to officially announce @usetildei launch and $6MM seed funding! Lifecycle marketing is continuing to evolve. We saw this and I personally experienced it with the introduction of mobile devices 15 years ago. “Mobile Lifecycle Marketing” was born. We are now moving into a new era, one with AI, LLMs and new channels (outside of push, email and SMS) we like to refer to as “social channels”. When coupled together it unlocks a new opportunity for brands and marketers to connect with their customers like never before. Social Lifecyle Marketing is now born. AI and LLMs are baked into Tildei's DNA, allowing the platform to immediately understand our customers' voice, goal, and values. Marketers can devise campaigns that turn social channels like @WhatsApp and @instagram DMs into personal shoppers, a concierge, or bespoke guide that tailors customer experiences at scale—without building out complicated journey flows. The foundation of Tildei is twofold: Elevate the marketer to empower the customer. By seamlessly integrating with your brand's universe—from websites and product catalogs to CRM data - Tildei becomes a digital embodiment of your brand, capable of engaging in meaningful, impactful conversations that authentically reflect your unique identity and values. I could not be more excited to build Tildei with my co founders Manisha Shah and Kevin Dutra (thank you Joe Teplow for introducing us). The Tildei team is passionate about empowering marketers and elevating customer experiences through AI-powered conversations. We're building a platform that allows you to create engaging, personalized interactions in minutes, not weeks. This milestone wouldn't have been possible without the trust and support of our investors. Their belief in our mission to revolutionize how brands connect with customers is both humbling and motivating. The round was led by @SusaVentures with participation from @LudlowVentures, @LererHippeau, @GradientVC, @VineVenturesLP Maccabee Ventures, @marceloclaure, @benln, @jasonlk and @mrsharma This is also the second incubated company out of @mxvcapital 😉 Want to see how Tildei can transform your marketing strategy? I'd love to show you personally. Shoot me a message and let's explore how we can take your customer conversations to the next level. Thank you to everyone who has been part of this journey. We're just getting started, and I can't wait to share what's next. You can learn more here tildei.com/post/a-note-from-…
