Automated direct mail platform with handwritten personalization

Advertising Services Los Angeles 11–50 employees Founded 2020 Privately Held

LettrLabs operates a direct mail automation platform that pairs robotics for handwritten card production with digital targeting and campaign management tools. The tech stack is sales and marketing-heavy (HubSpot, Zapier, Salesloft, Apollo, Gong), reflecting a business built around customer acquisition and retention rather than engineering complexity. Active hiring across growth, production, and support signals expansion beyond the core platform — warehouse automation and multi-facility manufacturing scaling are live priorities, positioning the company as much as an operations play as a software one.
