Memoir

YCombinator

Marketing campaigns from everything your team ships

Memoir turns what your team ships into marketing material. It connects to GitHub, Linear, Slack, customer feedback, and product analytics to understand what changed, why it matters, who should hear about it, and how to tell the story. From there, Memoir creates multi-touchpoint marketing across social, blogs, changelogs, demo videos, customer updates, and launch content, all in your company’s voice. It also watches what is getting traction in your market, learns from your edits and campaign performance, and gets better every time you ship. It is not a generic AI content tool. Memoir is a marketer with the soul of an engineer: it starts from the product source of truth and turns product velocity into market velocity.
