From stealth to $50M Series B, we’re excited to double down on Linx Security🔒 When we backed Israel Duanis and Niv Goldenberg at inception, we believed identity would become the central control layer of modern enterprise security. That conviction has only grown stronger. AI agents and non-human identities now outnumber humans inside organizations by roughly 80 to 1 – expanding the attack surface faster than traditional tools can handle. Linx's AI-native platform governs every identity in real time, and their newly launched Linx Autopilot brings autonomous, continuous enforcement to a problem that has long relied on manual processes. Congrats to the whole team on this milestone – we’re excited to keep building together alongside Insight Partners and Cyberstarts.

Contracting is the API of business. Every economic transaction between two parties runs on a contract – and yet the way contracts get negotiated has barely changed in decades. Ryan Daniels and John Sarihan built Crosby around the idea that this deserved a fundamentally different kind of law firm: one obsessed with speed, data, and AI, where every incentive points toward fewer turns – not more billable hours. We led their Series A, and we're proud to be back for their Series B.

Jean-Charles Samuelian-Werve’s grandparents arrived in France after fleeing the Armenian genocide. They rebuilt their lives from scratch, and ended up running small clothing shops in the south of France well into their late eighties. That spirit of creativity and resilience became the family inheritance. When JC was nine years old, he sat down at a computer and had what he describes as a transformative experience: “The idea that you have something in your mind, and then if you tell a machine, you can deliver it and show it to the world – that was a huge moment in my life.” He built his first website as a child, started selling websites to clients at thirteen, and co-founded Expliseat at twenty-two, creating the world’s lightest aircraft seat. But healthcare was the problem he couldn’t stop thinking about. When he was growing up in Marseille, JC’s parents were both psychiatrists. He had seen the dedication – as well as the broken tools – that defined the French healthcare system, and he dreamed of something better: something less reactive, more efficient, more humane. In 2016, he and co-founder Charles Gorintin launched Alan, a global platform aiming to deliver end-to-end personalised healthcare for all. Today, the company covers millions of members across five markets and is valued at nearly $6 billion. It rises to the demands of consumers, who crave simpler and more seamless options for staying healthy, as well as the need to innovate as chronic disease and ageing populations strain healthcare systems worldwide. Alan’s platform is one that’s both high-touch and high-tech, both preventive and highly personal. It’s a platform shift in care as consequential as the creation of hospitals in the 18th and 19th centuries, bringing healthcare to where people already are – on their phones, in their homes and at work. “When you start seeing society as a global civilization, you start thinking a bit differently about what you want to build,” JC says.

April 11th, 2026 in Paris: Come build the future of health at Alan x Mistral AI Health Hackathon. It'll bring together 30 builders with full access to Mistral's models, mentoring from Alan's product and medical teams, and a room full of people who take craft and impact seriously. Index Ventures will join for the day and sit on the jury with exciting challenges and prizes. Link is https://luma.com/t7rspaka cc Charles Gorintin Arthur Mensch Emil Schaefer Pari Vansjalia Francesco G Pontrandolfo Archita Sriram

Shardul Shah has spent nearly two decades at Index building a reputation for finding the right founders before anyone else does. His approach has always been the same: start with the people, go deep on the relationship, and trust that the returns follow. "The next relationship that we build depth in is the most important relationship. And that will lead to accessing, assessing, winning, supporting, and exiting great investments." It's a philosophy that runs through everything at Index. The goal, as Shardul puts it, isn't to scale for its own sake – it's to protect the craft and focus on founders and the relationships that make great outcomes possible. It's a philosophy that has shaped some of Index's most important bets – from Datadog to Wiz, Simile to Parallel Web Systems, and beyond. In a new deep-dive with Eric Newcomer, Shardul goes beyond the outcomes to cover: - How he thinks about founder conviction – and why he refuses to invest after only a Zoom call - How he pushes founders past their own sense of what's possible – and how he knows when to let them go - Why mid-size acquisitions fail, and what makes large ones work - The tension between being a board member and being a shareholder, and how to hold both honestly 🎧 Full episode: https://lnkd.in/gQsykYCD

Picture a future where hospitals run seamlessly, while practitioners focus on what matters most: the patients. Records are kept accurately, patients are admitted smoothly, diagnostic codes are generated efficiently, and billing is processed without bureaucracy. That is the future Parallel is building with AI agents that operate hospitals’ legacy software with speed and accuracy. In less than a year since launch, Parallel's AI agents have been rolled out across several dozen hospitals. Following the rapid rollout of its agents to automate hospital administration challenges, Index is leading the company’s $20M Series A round, announced today. We’re excited to join Paul Lafforgue, Chris Rydahl and the team as they work to make meaningful progress on one of healthcare’s most urgent challenges: delivering better care with fewer resources. Congratulations! https://lnkd.in/eaS9DcCs

"Conviction is the currency of progress." Our Partner Shardul Shah joined TBPN's John Coogan and Jordi Hays to talk about the decade-long founder relationship behind Wiz, why Index led the Series A two weeks after launch and the Series B two months after that, and what Google's $32B acquisition means for what comes next.

Assaf Rappaport showed up 45 minutes late to his first meeting with Index partner Shardul Shah. It didn't matter. The chemistry was immediate – the meeting stretched to 90 minutes, and Shardul spent the entire weekend turning the conversation over in his head. By Monday, they had a term sheet. That was the beginning of what would become a groundbreaking event: Google's $32B acquisition of Wiz. What Shardul remembers most isn't the term sheet or the valuation. It's the phone call on his birthday, when Assaf invited him to join the board. This is the philosophy that drove the investment from day one: back the people, not just the product. "A product and a market can change," Shardul says, "but extraordinary people are able to adapt and rebuild again and again." Check out the full feature in Globes: https://lnkd.in/eamqXTzs
