Postma wrote that revenue grew about 100% month over month from November 2020. Pieter Levels estimated the price at around $1 million from a reported $20,000 MRR; Postma did not disclose the amount.^{Source [2]}^{Source [1]}

Conversion.ai was built by the team behind Proof, and Postma moved into a strategic role there after the sale. The company later traded as Jarvis and then Jasper, co-founded by Dave Rogenmoser, J.P. Morgan and Chris Hull.^{Source [2]}^{Source [5]}^{Source [6]}

What happened

Danny Postma turned an ebook of headline templates into a headline generator in 2020, then rebuilt it on GPT-3 after getting early API access. After a TechCrunch mention in March 2021 it was acquired by Conversion.ai, the company later renamed Jasper, in a deal They Got Acquired describes as seven figures. The Headlime site still carries the acquisition notice.^{Source [2]}^{Source [7]}^{Source [1]}^{Source [4]}^{Source [3]}
