Today we’re announcing our $30M Series C, led by RPS Ventures, bringing our total funding to $100M. This milestone reinforces our conviction, validated by customers and backed by investors: AI systems won’t be operable or trusted at scale without an enterprise-ready Control Plane for AI. Making AI systems operable, governable, and trustworthy at scale is no longer optional; it is the prerequisite for adoption. That's the Control Plane for AI, providing the visibility and authority teams need across the agentic lifecycle with: + Standardized telemetry + Reliable evaluation + Continuous monitoring + Enforceable policy + Auditable governance We’re proud to be backed by long-term partners who see the same shift and are aligned on what comes next, including RPS Ventures, Insight Partners, Lightspeed Ventures, Lux Capital, Dallas Venture Capital, ISAI Cap Ventures, Dentsu Ventures, Mozilla Ventures, BGV, LDV Partners, and LG Ventures. Read our co-founders @krishnagade and @amitpaka blog to learn more about our vision for building the Control Plane for AI: fiddler.ai/blog/series-c?… Link to press release: fiddler.ai/press-releases…

Your evaluation TCO may be higher than you think. Every time an external LLM evaluates a trace, your LLM provider charges for it. That's your Evaluation Trust Tax, and it grows with every trace, every metric, and every token. That's why we built the Evaluation TCO Calculator. Compare external LLM evaluation costs against Fiddler Centor Models,* purpose-built, low latency, and cost-effective. Play around with the calculator and discover your TCO, whether you're running simple tasks or complex reasoning projects with LLM-as-a-judge. fiddler.ai/evals-tco-calc… *Fiddler Centor Models were previously known as Fiddler Trust Models.

Don’t miss tomorrow’s webinar! We've partnered with @1Password to unpack the identity challenges hiding inside every agentic deployment 📅 Register now to learn how to: 🔹 Separate agent identity from traditional machine identity 🔹 Understand why static security policies break when agents can reason and decide their own scope 🔹 Bring Zero Trust enforcement into real-time agent workflows with attestation and automated credential scoping All registrants receive an on-demand replay.

@1Password's Jeff Malnick has been thinking about agent identity longer than most. As VP of Engineering, Developer and AI at 1Password, he works on the security challenges that come with deploying AI agents in production, including how to scope, provision, and audit agent access in real time. Join Jeff and Krishna Gade for AI Explained: “AI Agents Have an Identity Complex” in one week.

You’re invited to our next AI Explained: “AI Agents Have an Identity Complex” 🔐with @1Password VP of Engineering, Developer and AI, Jeff Malnick! AI agents need access that changes in real time as they reason through what to do next. Most security frameworks were built for humans, not systems that decide their own scope. We will be covering: → What separates agent identity from machine identity and why static security policy breaks when agents can reason → Where Zero Trust enforcement has to live in an agent workflow and why real-time attestation beats standing policy → How to provision and scope agent credentials automatically without blocking the systems that depend on them 📅 May 14, 2026 at 10am PST 🔗 Register: fiddler.ai/webinars/ai-ex… #AgentIdentity #AISecurity #AI #ArtificialIntelligence #LLMOps #GenAI #AIAgent

AI coding sessions are ephemeral islands. Your agent crafts brilliant implementation plans, works through edge cases, makes architectural decisions. Then the session ends and all that reasoning evaporates. The next session starts fresh. The next engineer starts fresh. The code ships, but the reasoning lives only in memory. Most teams resort to copy-pasting between sessions, Google Docs, and Slack. The agent loses context every time. You spend ten minutes re-explaining the same problem. We solved this by using GitHub as a persistence layer for AI agent sessions: • Plans and decisions survive session restarts • Teammates can review and comment without context-switching • Agents reload full context from issues when work resumes • Complete audit trail of what changed and why AI agent sessions don't have to be throwaway conversations. When you make them collaborative and auditable, they become part of your development workflow instead of working around it. fiddler.ai/blog/github-ai…

Not many people can say they govern AI as a health system executive and use those same tools on patients every week. Stacey Johnston can. She is joining our next AI Explained webinar as Chief Information and Digital Execution Officer at Beacon Health System and a practicing hospitalist. Her take on AI governance, ROI mandates, and what clinical reality demands from technology is one you won't hear anywhere else. One week away.

We are excited to announce our next AI Explained, "Lessons from a Physician-CIO on AI Governance" 🏥 In healthcare, every AI decision has a patient on the other side of it. That changes everything about how governance gets built. Joining us is Stacey Johnston, MD, Chief Information and Digital Execution Officer at Beacon Health System and a practicing hospitalist. She is the executive approving AI tools and the physician using them on patients. We will be talking about: → What a structured AI approval process looks like when patient safety sets the standard → How ROI gets defined, measured, and enforced before any tool scales → What practicing medicine adds to governance decisions that spreadsheets alone can't capture 📅 April 23, 2026 at 10am PST 🔗 Register: fiddler.ai/webinars/ai-ex…

Webinar Invite: The Agentic Gap: What Enterprises Think vs. What Actually Works Enterprises are piloting agents, but most are still thinking in terms of models, not systems. Join Jeff Dalton, Head of AI and Chief Scientist at Valence, and Joshua Rubin, Head of AI Science at Fiddler AI, for a candid conversation on where agentic AI stands today and what it takes to move from ambition to deployment. Learn how to: 📍 Pinpoint how agentic architectures are evolving beyond single models 🦾 Understand how advances in memory, context, and orchestration are shaping next-generation systems 🎛️ Rethink evaluation for agents, and what it really takes to measure agentic systems Close the gap between enterprise AI agent expectations and what actually works, register to save your seat today. fiddler.ai/webinars/ai-ex…

Enterprises aren’t asking “can we build agentic systems?” anymore. They’re asking “can we trust them?” If you missed our recent AI Explained fireside chat on “How to Prevent Rogue Agents and Accelerate Enterprise AI Deployment,” Krishna Gade (CEO, Fiddler AI) and David Kenny (Executive Chairman, Nielsen) broke down why “rogue” agent behavior usually isn’t a mystery failure, it’s an infrastructure gap: Agentic systems can look “healthy” in dashboards while customers experience: 📍 incorrect or inconsistent answers 📍 policy violations and unsafe outputs 📍 ballooning cost + latency from runaway tool/model calls The fix: build a control plane early. David’s analogy nails it: You can’t improve what you can’t see - and you can’t enforce what you can’t measure. If you want the full blueprint, the recap is live on our blog: fiddler.ai/blog/prevent-r…

@krishnagade will speak at the Davos AI Summit 2026 (AI House Davos) Some themes Krishna will cover how enterprises can: 📍 See what an AI system is doing, in real time 📍 Trace decisions end-to-end across models, agents, and tools 📍 Govern systems at scale, across teams, clouds, and regulators, without slowing execution We will be sharing lessons from Fiddler AI working at the front lines of building a Control Plane for AI Agents, and why trusted AI infrastructure will be as foundational to this decade as cloud observability was to the last. #Davos #AISummit #AgenticAI #AIInfrastructure #AIGovernance #EnterpriseAI #TrustInAI

The Office of Management and Budget issued Memorandum M-26-04, implementing Executive Order 14319 on Increasing Public Trust in Artificial Intelligence Through Unbiased AI Principles. This memo mandates federal agencies to adopt minimum practices for governing AI systems. Key takeaways: 📍 Enhanced AI transparency measures include public reporting, third-party evaluations, and appeal mechanisms for impacted individuals 📍 AI systems must be in compliance by March 11, 2026 with factual, accurate outputs that acknowledge uncertainty 📍 AI systems must issue nonpartisan responses without ideological manipulation If you're interested in increasing transparency and trust in AI read the full blog: fiddler.ai/blog/omb-m-26-…
