Adam Wenchel
He was studying how AI fails before most people believed it worked. Now he builds the guardrails that keep everyone else's models honest.
Checkly
Checkly is a developer-first synthetic monitoring and reliability platform that lets engineering teams define uptime, API, and browser checks as version-controlled code. Built on Microsoft's Playwright framework and OpenTelemetry, it runs checks from 20+ global locations and layers in AI-driven root cause analysis. Founded in 2018 and headquartered with roots in Berlin, Checkly serves 1,000+ customers - including Vercel, 1Password, CrowdStrike, and Mistral - and has raised $32.25M, most recently a $20M Series B led by Balderton Capital in 2024.
ALIGNMT AI
ALIGNMT AI is a New York-based company building an enterprise AI governance and risk-monitoring platform for healthcare. Founded by MIT-trained machine-learning scientist Andreea Bodnari, it helps health systems, payers, and health IT vendors deploy AI while automating compliance with frameworks like ONC, ISO 42001, the NIST AI RMF, and the EU AI Act. Its platform continuously monitors production AI systems, audits for bias and fairness, and generates the audit trails regulators, boards, and customers demand - reportedly cutting compliance audit-prep time by up to 50%.
Haize Labs
Haize Labs is a New York-based AI safety and reliability startup that automates the red-teaming, stress-testing, and evaluation of large language models. Founded in 2024 by a trio of Harvard-trained researchers, the company builds algorithms that hunt for the inputs that make AI models misbehave - jailbreaks, failure modes, and edge cases - so they can be fixed before real users find them. Its 'haizing suite' and multi-turn attack engine Cascade are used by frontier model labs including OpenAI and Anthropic, alongside enterprises like Deloitte and MongoDB.
HoneyHive
HoneyHive is a New York-based AI observability and evaluation platform that helps engineering teams ship reliable AI agents. Built OpenTelemetry-native, it unifies distributed tracing, offline experiments, real-time monitoring, and human-in-the-loop annotation into a single continuous-improvement loop so teams can see not just what an agent output, but how it got there and where it went wrong. Founded in 2022 by Columbia roommates Mohak Sharma and Dhruv Singh, HoneyHive is used in production by enterprises including Commonwealth Bank, NVIDIA, MongoDB, and Pinecone, and raised $7.4M in total seed funding led by Insight Partners.
Vellum
Vellum is a New York-based AI development platform that helps companies build, evaluate, deploy, and monitor production-grade LLM applications and AI agents. Founded in early 2023 by three engineers who kept hitting the same wall - prototypes that demo well but break in production - Vellum gives teams a workflow builder, an evaluation suite, version-controlled deployments, and live monitoring so they can move AI from proof-of-concept to reliable production systems. The platform works with more than 150 companies including Drata, Redfin, Swisscom, and Headspace, and raised a $20M Series A led by Leaders Fund in July 2025.
Zubin Koticha
Zubin Koticha is the CEO and cofounder of Raindrop, a San Francisco startup building observability and alerting for AI agents, often described as 'Sentry for AI.' Before Raindrop, he cofounded Opyn, the DeFi options platform that pioneered the power perpetual (Squeeth), crossed $15B+ in volume, and was acquired by Coinbase. A UC Berkeley alum who taught himself to code there, he pairs a fascination with esoteric financial derivatives with bachata, deadlifting, and obscure geography trivia.
Agency
Agency (agen.cy) is a San Francisco company building the tooling layer for AI agents. Its flagship product, AgentOps.ai, is an observability, testing, and compliance platform that logs every decision an autonomous agent makes - so teams can see what their agents actually do, catch failures, and ship reliably. Founded in 2023 out of the city's AI hackathon scene, the company also runs an AI-agent consulting practice and raised $2.6M in pre-seed funding in 2024.
Braintrust
Braintrust is the end-to-end developer platform for shipping AI products. It connects evaluations, observability, prompt iteration, and an agentic optimizer (Loop) into one workflow so engineering teams can measure, debug, and improve LLM applications in production. Teams at Notion, Stripe, Vercel, Airtable, Instacart, Zapier, Ramp, Dropbox, Cloudflare and BILL use it to ship AI that doesn't silently regress.
WitnessAI
WitnessAI is an enterprise AI security and governance platform that helps organizations safely deploy AI at scale. Built on three pillars - Observe, Protect, and Control - its platform provides real-time visibility into all AI interactions (employee tools, internal models, AI agents, MCP servers), detects and blocks prompt injections and jailbreaks with over 99% accuracy using intent-based ML models, and enforces behavioral policies without code changes. With $85.5M in total funding, 500% ARR growth in 2025, and customers across financial services, telecom, airlines, and automotive, WitnessAI is positioning itself as the confidence layer enterprises need to move from AI experimentation to production deployment.
