Sean Mullaney (Seapoint) on Stripe's Router Play & Multi-Model Workflows
Seapoint CEO Sean Mullaney, a former Stripe local-payments lead, explains why the OpenRouter deal fits Stripe's DNA: routing to the highest-performing, best-cost option for the same developer buyer, with the premium justified by category leadership. He argues Ramp's router play is harder since CFOs don't dictate developers' tooling, and details how Seapoint uses OpenRouter to run 50-60 model experiments — finding smaller models often beat frontier reasoning models on simple sub-tasks — plus his daily multi-model 'panel of experts' workflow. He closes with a Seapoint update: post-seed public launch, all-in-one finance for startups, and an agent-driven pipeline shipping about a quarter of product work, from customer request to production in under 24 hours.
