Angie Muller is an American entrepreneur and the co-founder and CEO of Attunement, a San Francisco-based company that develops AI-powered compliance and clinical documentation software for behavioral health organizations. Attunement was part of the Y Combinator Winter 2024 batch.

Education

Muller holds a Bachelor of Arts in psychology from Barnard College, Columbia University. She also conducted research in applied neuroscience at King's College London, where her work focused on the intersection of cognitive science and clinical practice.

Career

Prior to founding Attunement, Muller held partnership roles at Stripe and NVIDIA. At Stripe, she worked with early-stage venture-backed companies to accelerate adoption of payment processing infrastructure. At NVIDIA, her work centered on partnerships with early-stage machine learning startups, with a focus on synthetic data generation, data labeling, and annotation technologies used to train AI models.

In 2023, Muller co-founded Attunement alongside Briar Smith, who serves as the company's CTO. The company builds AI-powered compliance and clinical documentation software designed specifically for behavioral health organizations, a sector subject to intensive regulatory scrutiny under frameworks including HIPAA and Medicaid audit requirements. Behavioral health providers face particular documentation burdens because funders and regulators require detailed, longitudinal records to substantiate clinical decisions and billing — a requirement that can consume several hours of a clinician's working day. Attunement's platform is designed to keep organizations continuously audit-ready, reduce documentation costs, and protect revenue by automating compliance tasks that would otherwise fall to clinical staff.

The company's core product is described, in its own materials, as a "clinical memory layer" — a system that supports multimodal workflows including interpreting assessment-heavy records, reviewing charts at volume, maintaining longitudinal clinical understanding across patient histories, and preparing documentation packages for audits and quality reviews. The platform emphasizes HIPAA-compliant infrastructure and is designed to keep clinicians in an oversight role rather than removing human judgment from the process. By handling administrative documentation burdens, the system is intended to free clinicians to direct more of their time toward direct patient care.

Attunement participated in Y Combinator's Winter 2024 batch, one of the most competitive early-stage accelerator programs in the technology industry, and is headquartered in San Francisco. The company operates at the intersection of workflow automation, healthcare technology, and artificial intelligence.
