Before

    Cofounder and CEO
    Years:
    2022 to 2023

    I reinvented the Ambrosus ecosystem as AirDAO, a layer 1 network, and tripled the team. Its token reached a market cap of more than $100 million. AirDAO raised more than $11 million, including $2 million from DWF Labs in 2022 and $7.5 million in 2023. I cofounded the AirDAO Foundation in October 2022 and handed the project to a council elected by its community.

    Maker of Mu Tag, a small tag that uses AI to warn you before you leave something behind. We raised $250,000 on Kickstarter and Indiegogo, and it sold in more than 69 countries. I am a named inventor on US patent 10,154,379, which covers it. Informu assigned the patent to MuTag Tracking LLC in 2022. MuTag Tracking asserted it against Apple over AirTag in a federal case in Texas in 2023, and the parties resolved the case that November. Google Patents lists 11 later patents and applications that cite the patent, 7 of them from Apple.
