Strand Therapeutics is a clinical-stage biotechnology company headquartered in Boston, Massachusetts, founded by biological engineers out of MIT — including Jacob Becraft (CEO), Tasuku Kitada (President, Head of R&D), Ron Weiss and Darrell J. Irvine — around what the company describes as the first mRNA programming language. Strand engineers programmable genetic medicines across three named platforms: SignalPath LNPs for tissue-selective delivery of mRNA payloads, SignalLock RNA which restricts expression to target tissues and deactivates it elsewhere, and SignalScript RNA for self-replicating and circular RNA constructs. Its clinical pipeline includes STX-001, STX-003 (systemic tumor delivery, entering the clinic in 2026) and STX-005 (in vivo CAR T), targeting solid tumors, blood cancers and autoimmune disease. Strand operates no developer program and publishes no API, SDK, webhook or machine-readable specification of any kind; its corporate site is a static Webflow property behind Cloudflare with no content API, no feed and no sitemap. It is catalogued here because it appears in the API Evangelist secondary-market harvest backlog, and this profile records the honest zero.
