Runable, founded in 2025 to provide AI-agent-driven growth infrastructure for small businesses, has raised a twenty-one-million-dollar Series A led by Susquehanna Venture Capital and Nexus Venture Partners at a sixty-five-million-dollar valuation. The platform handles website creation, advertising campaign management, SEO, social media, and AI customer chatbot deployment through a single agent interface designed for operators without technical staff. Runable reached two million dollars in annualised revenue within three weeks of activating payments in March 2026. The velocity of early monetisation — and the decision to pursue small business customers rather than the enterprise segment that most well-capitalised AI companies are competing for — positions the company in a market segment where the competitive intensity is lower and the total addressable market is, by volume of potential customers, substantially larger. The SMB marketing automation space has historically been served by tools that required meaningful operational overhead to deploy; the agent-native approach, if it delivers on its promise of accessible autonomous execution, addresses the adoption barrier that prior generations of tools could not fully overcome.
