Restorative and health-Enhancing Sleep Time (REST)

The Advanced Research Projects Agency for Health (ARPA‑H) is seeking innovative, home‑based, closed‑loop sleep‑technology solutions that can detect and respond to health‑relevant sleep microstructures in real time. Proposers must submit a Solution Summary, a full Proposal, and optionally a Pitch; each will be evaluated on distinct criteria (encourage/discourage, invite/not‑invited, selected for negotiation/not‑selected). The solicitation has been amended multiple times, with the most recent amendment (Amendment 11) updating Section 4.5 and clarifying pitch session dates. Key points include: • Solution Summaries are limited to 6–8 pages (depending on whether one or both technical areas are addressed). • Proposals must include a detailed Basis of Estimate and, for Technical Area 1, a cost‑share strategy. • The solicitation is open for response until 13 Oct 2026, with no pre‑bid meeting or site visit required.
