Top Closes $5 Seed Round has said to have closed a $5 million seed round. Rebel Fund, Eastlink Capital, Pioneer Fund, Y Combinator and several angels took part in the round. The startup has 40 paying customers today, with revenue increasing by around 25% to 30% per month. The founders were former employees at Dover, another Y Combinator company from the 2019-era, working with GPT 3 in early 2020 when its beta was released. While at Dover, they built generative AI applications to write recruiting emails, job descriptions and the like, but they noticed that they were spending too much time on their prompts and couldn’t version the prompts in production, nor measure their quality.
