Overview
Krishna Gade is founder and chief executive officer of Fiddler AI, per the company About page. Fiddler’s mission is to build trust into AI. The company began with explainability for machine learning models, expanded to observability tracking how models change over time, and today positions itself as the Control Plane for AI Agents — enabling organizations to deploy high-performing, compliant, and secure AI systems at scale.
Gade co-founded Fiddler with Amit Paka, who serves as founder and chief operating officer per the leadership roster. Gade’s prior employers listed on Fiddler’s About page include Facebook, Twitter, Pinterest, and Microsoft — experience cited alongside a team drawn from Meta, Google, Lyft, X, Microsoft, and high-growth startups.
Fiddler’s Series C blog post co-authored by Gade and Paka articulates why agentic AI requires control planes analogous to Kubernetes and observability platforms in traditional software — a governance infrastructure thesis central to 2026 enterprise AI adoption debates.
Role
As founder and CEO, Gade leads Fiddler’s product vision, fundraising, and public thought leadership on AI control planes. The About page states Fiddler provides visibility into AI reasoning and behavior, detects bias, toxicity, and data leaks, and enforces policies — operationalizing responsible AI through continuous monitoring, enforceable policies, and auditable accountability.
Gade’s Series C announcement describes Fiddler’s evolution from industry-first enterprise explainability through data-drift observability to governance controls for agentic systems where observation alone cannot prevent policy violations or unbounded cost.
Under Gade, Fiddler serves Fortune 500 customers and holds recognition from CB Insights, Gartner, Forrester, IDC, MAD landscape listings, Defense Innovation Unit success memo, and CB Insights AI 100 per About page disclosures.
Background
Fiddler’s About page lists Gade’s prior roles at Facebook, Twitter, Pinterest, and Microsoft without detailing titles or dates on the excerpt reviewed. His public identity is tied to experiencing firsthand the pain of ML models making consequential decisions teams could not explain — the founding insight behind Fiddler’s explainability origin story in the Series C post.
Gade and co-founder Paka describe building explainability deployed at scale at some of the largest institutions including the U.S. Navy before expanding into observability and control — a customer profile signaling regulated and defense-adjacent AI governance requirements.
Fiddler’s culture values — humility, respect, kindness, transparency, collaboration — frame Gade’s leadership presentation on the About page reviewed July 11, 2026.
Career
Gade’s career narrative on cited Fiddler pages spans big-tech ML platform experience and serial category creation inside Fiddler: explainability, AI observability, and AI control planes. The Series C post argues agents are distributed systems wearing a prompt — requiring causal, policy, measurement, and economic control forms at scale.
Gade connects Fiddler’s control plane thesis to NIST AI RMF lifecycle governance, ISO/IEC 42001 management systems, and EU AI Act record-keeping requirements — framing product architecture as compliance-enabling infrastructure rather than optional tooling.
Board members listed on Fiddler’s About page include Raviraj Jain (Lightspeed), George Mathew (Insight Partners), Timothy Murphy (RPS Ventures), and Maria Martinez — governance relationships accompanying Gade’s CEO role through Series C.
Company Journey
Fiddler’s journey under Gade moved from solving model explainability pain to defining AI observability as models drift in production, then to control planes as Fortune 500 companies deployed AI agents requiring runtime policy enforcement. The About page states when governance becomes necessary, a Control Plane always emerges.
January 27, 2026 Series C announcement: $30M round led by RPS Ventures, bringing total funding to $100M per the blog post co-signed by Gade and Paka. Investors listed include Insight Partners, Lightspeed Ventures, Lux Capital, and others named in the post.
Fiddler’s recognition portfolio — Gartner Market Guide for AI Evaluation and Observability, Forrester Responsible AI Solutions Landscape, IDC Generative AI Governance ProductScape, CB Insights AI Agent Security leadership — documents category validation during Gade’s CEO tenure.
Leadership
Gade’s leadership combines technical authorship on foundational AI infrastructure topics with CEO fundraising authority. The Series C post’s depth on distributed systems, trust tax, and context graphs signals hands-on architectural engagement beyond executive figurehead roles.
Co-leadership with COO Amit Paka — who co-authors major company announcements — suggests operational partnership balancing Gade’s product and category-definition focus with execution scale.

Why This Founder Matters
Krishna Gade matters because he names and productizes the Control Plane category for agentic AI — a framing enterprises need as MIT-cited GenAI pilot failure rates and trust taxes block production scale. Fiddler under Gade unifies telemetry, evaluation, policy, and evidence for regulators.
His explainability-to-governance arc mirrors how AI governance tooling matures: understand decisions, monitor drift, then enforce policies at runtime for autonomous agents.
For Brel Digital readers, Gade represents infrastructure-layer AI Governance founders building the nervous system—not just the senses—for enterprise AI.
