Autoblocks is a collaborative evaluation and testing platform for LLM-powered products, designed to help teams build safe and reliable AI applications. It enables engineers and subject-matter experts to define test cases, run evaluations against datasets, grade outputs and track quality over time so AI features behave as intended before and after release. Founded in 2022 by Adam Nolte and brothers Haroon and Hamza Choudery, with Haroon as CEO, the New York-based company raised a $2M seed round in 2023 from Core Innovation Capital and Kyber Knight Capital.
