Elliot Katz is a New York-based technology executive known as co-founder and chief technology officer of Novellia [1][2][3]. He has built his career primarily in engineering leadership roles across healthcare and consumer technology companies in New York City [2].
Katz began his engineering career at Zocdoc in 2012, serving first as a software engineer and then as a senior software engineer, a tenure that lasted through early 2017 [2]. He subsequently joined Wonder, the company behind AskWonder.com, where he progressed from technical lead to engineering manager and head of product engineering, and ultimately to head of engineering and data, overseeing that function until May 2020 [2].
From 2020 to 2023, Katz held engineering leadership positions at Thirty Madison, first as director of engineering and later as senior director of engineering, a period during which he was responsible for broader engineering operations at the healthcare company [2].
In January 2023, Katz co-founded Novellia, where he serves as chief technology officer, applying the engineering and leadership experience gained across his prior roles at Zocdoc, Wonder, and Thirty Madison [1][2][3]. He holds a Bachelor of Science in Computer Science from Columbia Engineering, which provided the technical foundation for his subsequent career in software engineering and technology leadership [2].

Insights & ideas
Elliot Katz's ideas span two distinct areas across these sources. In relationships, he argues that women want men to act as leaders rather than deferring every decision to them, describing leadership as noticing situations that call for action and stepping forward rather than either being domineering or passively asking "what should I do" [1]. He stresses that indecisiveness reads as weakness, that men should plan dates and make decisions rather than leaving choices entirely to women, and that while big decisions should be made together, women find it frustrating and even infantilizing when men hand off all decision-making [1].
In his later work with Mixis, Katz argues that fully autonomous AI agents are too unreliable for business use, citing OpenAI's own benchmarks showing high hallucination rates in its models [2]. His core idea is "colleague-in-the-loop" AI, where humans verify or correct AI outputs at key steps before consequential actions like sending emails, preserving efficiency while avoiding undetected errors [2]. Applied to law, he contends AI can handle much of the basic work but cannot replace human judgment, interpretation, and risk assessment, meaning complete products require combining human and artificial intelligence [3].

Elliot Katz discusses Mixis, an AI platform he co-founded that deploys colleague-in-the-loop AI agents to address hallucination and accuracy problems in autonomous AI systems. He explains how Mixis allows humans to verify or correct AI outputs before they cause harm, using examples like AI agents that draft customer follow-up emails, and demonstrates the ease of creating agents in plain English on the platform.

The speaker discusses how AI agents can assist attorneys with legal work but cannot replace human judgment entirely. They explain that clients seek lawyers for interpretation, judgment, and risk assessment beyond basic legal knowledge, and that combining human intelligence with artificial intelligence is necessary for a complete legal product.
