Mitko Simeonov (Dimitar Simeonov) is the founder and CEO of Pioneer, a San Francisco startup that uses large language models to help climate tech companies win government grants, contracts and incentives in a fraction of the usual time. A Bulgarian math olympian turned MIT-trained AI engineer, he shipped machine learning to hundreds of millions of users at Twitter before building Pioneer, which raised $2.9M in seed funding led by Blue Bear Capital in late 2023. He describes himself as a compulsive problem solver and writes a long-running blog about thinking independently.
