Top Tech Startups in United States in 2026

Ethos is on a mission to transform how banks govern their AI and machine learning models. We're an early-stage startup in NYC backed by leading investors, including Better Tomorrow Ventures and Capital One Ventures. AI and machine learning models are already used today for many of the most critical decisions in society. Especially in financial services, this technology comes with deep questions around testing and governing these models to make sure their behaviors are trustworthy. We started Ethos because we saw firsthand the critical need for a modern platform for Model Risk Management in financial services. Changing technologies and regulatory requirements pose huge challenges for the industry, as well as enormous opportunities for positive change. At Ethos, you will be a fundamental part of this change.

Hiring has a trust problem. Fake candidates, stolen identities, proxy interviewers and AI-fed answers are now common enough that most teams have met one without knowing it. A resume is easy to fake. An interview is easy to outsource. By the time it surfaces, the cost has already landed on the team. Aperture is the human intelligence platform. We make sure the person you hire is the person who interviewed. We bring identity verification, candidate fraud detection, background verification and threat intelligence together with adaptive AI interviews and λ-CORE, our candidate evaluation engine, so hiring teams can see who is real and who is actually good long before a final round.
