    'If you implement observability with something like Braintrust inside of your internal AI gateway it’s really effective. What a lot of great companies do is they add logging into their AI gateway. What that means is if you’re a new team and you don’t know what evals are, you can get access via this gateway and start using the model and everything gets logged for you. What will eventually happen is if your product starts working you’ll say ‘I’d like to do evals’ and you can see all of the logs from people using your product to get started crafting this into something you can use to make your product better.' cc Ankur Goyal

  • Today's newsletter features our latest profile of Hasan Imam and Obsidian Security. We take a look at Hasan's journey from Bangladesh to Silicon Valley, where he had a series of “mini careers” that tested his resilience and broadened his skillset - ultimately landing him at Obsidian in 2021. Today, Obsidian is helping Fortune 1000 and Global 2000 companies protect their most critical SaaS applications, and beats some of the biggest and most established security platforms more than 80% of the time in customer bake-offs. And now, with AI agents set to autonomously access these platforms, Hasan sees Obsidian's opportunity expanding dramatically. Read more 👇

    "I didn't know what came next, but I knew I couldn't fail." Hasan Imam drew on that resolve when he stepped in as the CEO of Obsidian Security in 2021. Fast forward to today, and Obsidian is the fast growing leader in SaaS and agentic security, for Global 2000 companies. “We’ve always seen SaaS as the foundation of modern business,” Hasan says. “With AI agents, the stakes go up dramatically. The systems that run enterprises will be run by software, and securing those interactions will define the next era of cybersecurity.” Read more at the post in the comments field below. cc: Glenn Chisholm, Xinran Wang, Khanh Tran, Matt W., Brian Murphy, Chithra Rajagopalan, Paul Luongo, Alfredo Hickman, Tina Lei, Corey Elinburg, Ish Cheema, Priya Balakrishnan, Greylock Partners, Wing Venture Capital, Menlo Ventures, Norwest, IVP, GV (Google Ventures), Sunil Seshadri, Gaurav Garg, Venky Ganesan, Promod Haque, Somesh Dash, Karim Faris, Sangeen Zeb

    When I became CEO of Obsidian four years ago, the company was at a tricky spot. Covid had upended our pipeline, revenues were under $1M, and the security market was shifting fast. Some people may have looked the other way but I saw the opportunity. We just needed to make a few pivots. So, we made some tough cuts, doubled down on SaaS security when most vendors weren’t paying attention, and started preparing for the era of AI takeover. Fast forward to today, Obsidian is protecting some of the most discerning security teams in the Global 2000. And in head-to-head bake-offs, we don’t just compete with the biggest names in security, we win 80% of the time in a side-by-side PoV. Enterprises are starting to replace pre-existing solutions with Obsidian. We are delivering outcomes not another tool in the toolbox. Every hardship brings an opportunity to stand out. It takes grit, determination, and (let’s be honest) a fair bit of stubbornness. That mindset isn’t just mine, it’s how the entire Obsidian team operates. And that’s why we’ve not only survived, but thrived. Huge thanks to Asheem Chandna and Greylock Partners for sharing our story. Appreciate the partnership and the reminder that the “hard times” often make the best foundations (even if they don’t feel like it at the time).

    “A lot of code that AI models spit out is not fundamentally secure." Vineet Edupuganti, CEO of Cogent Security, shared more about how he's seeing AI accelerate the pace and complexity with which attackers are working. "What we’ve seen is that the volume of vulnerabilities, applications, and infrastructure, has skyrocketed over the past year. The thing that’s most scary for me is looking at what now attackers are capable of, and juxtaposing with that what defenders are doing. And the dynamics for defenders are there’s a lot of more work to do that people to do it."

  • When Hasan Imam stepped into the role of Obsidian Security's CEO in 2021, he saw an overlooked opportunity: the chance to build a disruptive approach to SaaS security at a time when no other vendor was addressing the problem head-on. Yet he never pictured himself leading a cybersecurity company in Silicon Valley. “I’ve never had a grand plan for my life,” he says. “It was always about doing my very best in whatever situation I was in.” This mindset took him from Bangladesh to Silicon Valley, where he had a series of “mini careers” across engineering, entrepreneurship, and sales that tested his resilience and broadened his skillset - ultimately landing him at Obsidian. Four years later, Obsidian is helping Fortune 1000 and Global 2000 companies protect their most critical SaaS applications, and beats some of the biggest and most established security platforms more than 80% of the time in customer bake-offs. Yet what excites Hasan the most? "What’s still in front of us," he says. SaaS security has become a critical part of the AI agent revolution. While there will be a ton of value created by agents, they also open up new attack surfaces at a scale never seen before. Protecting SaaS activity becomes non-negotiable. "This is the kind of opportunity you build a generational company around," Hasan notes, "and that’s the journey we’re on." Read our latest profile. Link in the comments.

    We raised $250M to accelerate our work in building AI’s unified compute layer 🚀! Thank you to our entire team for working so hard and bringing so much value into the world. In the past year, we’ve released AI inference at scale that’s now powering trillions of tokens, made AI workloads 4x faster and 2.5x cheaper for our customers, and welcomed 10K’s of new developers. The round was led by Thomas Tull’s US Innovative Technology, with DFJ Growth joining and with participation from all existing investors including GV (Google Ventures), General Catalyst and Greylock Partners. This brings our total capital raised to $380M across three rounds since our founding in 2022. Read more in the comments ⬇️

    It’s hard not to be enamoured by AI agents right now. They feel like super-smart teammates – chaining tasks, pulling data, running workflows. But in the past few months working with customers, we’ve seen just how risky this gets when it happens at scale. Here’s what’s really going on: The go-to low-code/no-code AI agent platforms are Microsoft Copilot and ChatGPT Enterprise Companies are spinning up thousands of agents – some just experimenting, others already in production. Most agents operate inside SaaS, with little to no oversight. And the risks are big: ** Agents pull 16x more data from SaaS apps than human users ** They’re given 10x more permissions than they actually need ** Many agents are left abandoned after pilots or left publicly accessible via URL, creating lingering security risks waiting to be exploited **Agents are often spun up with superuser privileges and shared with lower-privilege users – great for productivity, but leaving a setup wide open to abuse When something that powerful is misused – or worse, compromised – the blast radius is massive. That’s why we believe AI agent security can’t be a bolt-on. It has to be part of SaaS security itself. Today, we’re launching AI Agent Security at Obsidian – the first purpose-built solution to protect SaaS apps and data from rogue agents. What does that mean in practice? **Real-time visibility into every agent and its connections **Continuous monitoring and audit trails of agent access across SaaS **Proactive defenses to stop misuse before it spirals **Securing SaaS has been our mission from day one. And because AI agents live inside SaaS, no one is better positioned to protect what matters most. This launch is a big step forward – not just for Obsidian, but for every enterprise looking to scale AI safely. If you’re exploring AI agents, here’s where to start: https://lnkd.in/gw3vNWYM Thank you to the entire Obsidian team for the hard work that made this launch possible, and to our customers and partners for the shared commitment to scaling AI responsibly and securely across the enterprise.

  • AI agents are being rolled out quickly across organizations, often without much thought to security. That's why we - at Greylock Partners - are excited to see Obsidian Security debut SaaS AI agent defense, giving enterprises the first purpose-built solution to govern how AI agents access data in SaaS environments. Congratulations to Hasan Imam and the entire Obsidian Security team on the launch! 👉 Read more: https://lnkd.in/gdx63Z9E cc Asheem Chandna
