Tenex Labs

Tenex is an AI transformation and engineering firm working with companies that want to move from AI-absent to AI-native without commissioning six-month strategy decks. Its work spans three tracks: function-specific audits that surface AI use cases, transformation partnerships that pair change management with custom tooling, and outcome-based engineering squads where clients pay for shipped features rather than logged hours. The launch is anchored by a 38-minute masterclass on AI evaluations recorded with Viv Trivedi, who works on applied research at LangChain Labs , aimed at operators and founders who keep hearing that evals are the hard part of shipping reliable AI and want a working mental model rather than a vocabulary list. The company is run by two managing partners. Alex Lieberman is best known as the co-founder of Morning Brew, the business media company that sold to Business Insider for $75 million in 2020, and has since founded Storyarb, Distro, and growthpair. Arman Hezarkhani previously founded venture-backed AI companies, helped scale Google's Cloud and AI platforms for developers, and taught computer science as an adjunct at Carnegie Mellon. The timing matters because enterprise AI budgets are shifting from proofs of concept to production, where the bottleneck is measurement rather than model access. Evals, the discipline of scoring whether an AI system actually did what it was supposed to do across changing inputs and prompts, are how teams catch regressions before customers do, and LangChain has been pushing this thinking with releases like its Eval Engineering Skill, which helps coding agents build evals from repository context and agent traces . Pairing that expertise with Tenex's operator-side view of enterprise rollouts is the pitch behind this launch.
