Incandor

Incandor is a San Francisco based Y Combinator (Spring 2026) startup building behavioral intelligence infrastructure for fraud and abuse detection. Rather than relying on identity verification at account creation, Incandor constructs a behavioral map of every user on a platform from how they physically interact with an app or website — mouse dynamics, keystroke timing, scroll patterns, and on mobile how a device is held. It requires no fraud labels and no enrollment period, working from the first session. At the individual level it identifies account takeovers with greater than 99 percent accuracy; at the population level it separates out coordinated fraud rings, mule operators, shared operators, bots and agents, and coerced or duress sessions. Incandor is delivered as a programmable API and a client-side telemetry SDK rather than a black-box risk score, letting fraud teams combine behavioral signals with their own transaction history, customer records, and business rules. It collects only behavioral signals — not what users type, read, or view — keeping user data private by design. The company was founded by Matthew Yekell (CEO) and Luc Rosenzweig (CTO), both Stanford CS graduates. This profile is maintained by the API Evangelist network; the developer platform is currently early access.

Incandor is profiled on the APIs.io network. Tagged areas include Company, Fraud Prevention, Anti-Fraud, Behavioral Biometrics, and Account Takeover.

Incandor’s developer surface includes support and 3 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/incandor: open an issue to ask a question, or submit a pull request to add artifacts.
