AI is ready. Trust isn’t. Today, we’re making something official. JetStream Security Inc. has raised $34M, led by Redpoint Ventures with participation from the CrowdStrike Falcon Fund and industry leaders, to solve a critical enterprise problem: how to trust the AI systems already operating in production. AI now calls APIs, accesses data, inherits permissions, and consumes budget. But when boards ask simple questions like where it is running, what it is doing, who owns it, and what it costs, many organizations cannot answer with confidence. The gap isn’t model performance. It’s governance. AI has moved from experimentation to infrastructure. It acts under credentials and makes decisions with real financial and operational impact. Without visibility and accountability at runtime, trust breaks down. When trust breaks down, adoption slows. We built JetStream around a simple belief: Governance enables trust. Trust unlocks advantage. Governance is the control layer that makes AI visible, attributable, and defensible in production. Our founding team—Raj Rajamani (CEO), Jared Phipps (COO), Jatheen Anand (CTO), and Venu Vissamsetty (Chief Architect)—has led product, engineering, and go-to-market at some of the most influential security companies of the last decade. We’ve built platforms that protect the world’s largest enterprises, scaled organizations through hypergrowth, and navigated the security challenges that emerge with every new computing paradigm. AI is ready for takeoff. Now it needs governance-grade trust. Read the Fortune Magazine article: https://bit.ly/46X2urt Learn more: https://bit.ly/4u7cTup

Huge moment for our team: Slang AI has raised a $36M Series B, led by U.S. Venture Partners, bringing our total funding to $68M. 🎉🎉🎉 We built Slang AI because nearly half of restaurant calls go unanswered. When no one picks up, that guest moves on. That means missed reservations, missed events, and missed opportunities to capture guests who are ready to book. Enter Slang - the AI Superhost for restaurants and your staff’s favorite teammate. Like your best host, Slang AI books reservations, answers questions, and captures private event leads. It recognizes VIPs and carries their preferences forward, so every interaction feels personal. It answers every call, 24/7. Since launching, Slang AI has: ✅  Served 2,000+ restaurant locations globally ✅  Handled 25M+ guest calls across 10M unique guests ✅  Delivered 95%+ guest satisfaction ✅  Driven up to 20x ROI for operators This Series B allows us to bring the Superhost to every restaurant even faster… and to make it more personal, more proactive, and more intelligent. Slang will remember more about every guest, bring them back through thoughtful outreach, and give operators real-time insight into their guest experience and performance. We’re grateful to partner with U.S. Venture Partners, Thayer Investment Partners, Claire Hughes Johnson (former Stripe COO), and our existing investors Homebrew, Stage 2 Capital, Active Capital, Wing Venture Capital, Collide Capital, and Underscore VC. To all the operators who trust Slang AI to represent their brand every day: We’re deeply grateful to be part of your team. Your trust, your partnership, and the way you’ve embraced the AI Superhost is the reason we are here today. Finally, an endless thank you to the team at Slang AI for the grit, care and pride you bring to building technology that helps restaurants deliver true hospitality to every guest. This milestone reflects the thoughtfulness and dedication you've put into earning operators' trust. And if you want to help build the world’s leading AI company in hospitality, come join us. We’re just getting started. 🔗 Read the full announcement: https://lnkd.in/eVrje6Ts

Thrilled to share that Mews has closed our Series D—$300M at a $2.5B valuation. We're welcoming EQT Group, Atomico, and HarbourVest Partners alongside our existing partners Kinnevik, Tiger Global, and Battery Ventures. Having investors of this caliber in our corner is both humbling and extremely energising. This funding lets us double down on our core mission: making every hotel more hospitable through outstanding technology which does its best work in the background. With our integrated platform, we're positioned to harness AI to deliver real insights and real profits to our hotel partners—moving from technology vendor to true business partner. Most of all, this milestone belongs to the Mews team. The people who show up every day, scale new heights, and somehow keep exceeding already sky-high expectations. I couldn't be prouder of them all today. https://lnkd.in/e5Yn5gX5

We just raised $25M to make getting together feel human again. Work has been optimized into oblivion. Calendars are full, hearts are empty, and every conversation feels like a thread to respond to later. What the world actually needs is spark. The kind that leads to laughter, debate, ideas, and “holy sh*t, we should totally do that” moments. BoomPop uses AI to remove the painful parts of planning events and travel, so people can do what tech can’t: feel something. We’re proof that efficiency and soul can coexist, and that the best ideas happen in person, not inboxes. We've brought in two industry veterans who get it—Craig Dooley, CIS, CITP, VP & General Manager of BoomPop Studio (our events agency), and Indrajit Bavan, VP of Partnerships. We're thrilled to welcome them to our team during such a pivotal moment. This round was led by Gaurav Garg at Wing Venture Capital with participation from Atomic, ACME Capital , Four Rivers, Thayer Investment Partners, FOG Ventures, Gaingels, Zypsy, and individual investors including Alex Rodriguez (14x MLB All-Star and investor), Brian O'Malley (HotelTonight, Fora Travel), Dane Glasgow (CPO of Paramount), Christopher Payne (former President of DoorDash)—amoung other Silicon Valley founders. Together, they help us build gatherings that stick with you. We aren’t meant to live contactless lives. Let’s build striking ones. → Read the Crunchbase article https://lnkd.in/entHzjYV
