Laurence raises $5.8 million to automate performance marketing

After wrapping up Y Combinator's Winter 2026 batch, we've raised $5.8 million in total funding to grow and scale Laurence. Our seed round was led by Susa Ventures and Box Group, with participation from Jump Trading, SV Angel, Scribble Ventures, Roar Ventures, and angels from OpenAI and Amazon.

Laurence started with the key insight that we could automate advertising the same way quant firms systematically trade markets.

Our results prove we're onto something special: Laurence autonomously executes tens of millions of dollars of Amazon ad spend, driving a 15-40% improvement in total net profit after margin and ad spend within a month of onboarding.

We've only just scratched the surface: this funding allows us to continue perfecting our models and algorithms to profitably automate Amazon PPC for brands of all shapes and sizes, from health supplement brands to pet electronics to home cleaning products.

We're also beginning a closed beta with our existing customers for Laurence to automate ad spend on other platforms: ChatGPT, Google, Meta, TikTok, Walmart, and more.

We believe in a world where brands don't have to wrestle with underperforming agencies and pay for wasted clicks. This funding takes us one step closer to that vision, and I couldn't be more excited to keep pushing harder every day.

Thank you to our early customers for taking a bet on us when we were just an unproven idea: I'm proud of the results we've been able to drive for you all.
