Memoir

Memoir, operated by Tachyon Labs, Inc., is an AI-powered marketing automation platform in Y Combinator's Spring 2026 (S26) batch. It connects to a company's development and product tools such as GitHub, Linear, and Slack and turns shipped product updates into multi-channel marketing content: social posts, blog posts, changelogs, demo videos, and customer updates generated in the company's brand voice. The product is organized around "Memory" (Atlas) for building context about a company and "Motion" (market-motion) for producing and distributing content as teams ship features. Memoir is a marketing SaaS product; as of this profile it exposes only a private authenticated backend (api.trymemoir.ai returns 401) and publishes no public developer API, documentation, or SDKs.
