Alumni Q&A
- How did you decide to apply to Y Combinator? What was your experience applying, going through the batch, and fundraising at demo day?
- The founders applied at the encouragement of Brian Chesky, who had previously hired one of them (Shaun) at Airbnb. During the batch they worked with partners Garry, Ooshma, and Aaron, improved product velocity and customer acquisition, and signed a $1.3M term sheet with a major media brand.
- What's the history of your company from getting started until the present day? What were the big inflection points?
- The company grew out of Tom and a co-founder's work on Covid-19 logistics applications using AI models for HHS and the US DoD, where they found the interfaces from integrators like IBM, SAP, and Deloitte unusable. They started with a contract from the second-largest US health insurer to automate data storytelling for its self-insured employer line, using classical and Bayesian statistics with DBT, then pivoted away from healthcare to center the product on LLMs after GPT-3.5 launched. They recently closed a $1.3M enterprise contract.
