Thunder

Thunder is building AI agents for B2B growth, starting with paid ads. Our platform gives growth marketers the same 100x leverage that engineers are getting from tools like Claude Code and Codex. Rather than sell another piece of software into an already fragmented stack, Thunder sells the entire outcome. Customers give us responsibility for their paid channels, and we use our software to own strategy, execution, and results. This creates a tight feedback loop for improving our agents: whenever we encounter a recurring workflow, we look for a way to automate it and operationalize it across customers. Thunder raised a pre-seed in late 2025 and is backed by early leaders at OpenAI and HubSpot. We're live with paying customers, from high-growth Series A-C companies to larger enterprises, and are using our product to run their paid channels end-to-end.
