About the company and entrepreneur

Damika Oy is a company based in Lahti, Finland. Entrepreneur Mr. Mika Wahlman founded Damika Oy in 2002, and we’ve been going strong ever since. Damika Oy is a multi-brand company, including PC-APU, Ruuma.fi, and now the Bitcoin T-Shirt Club.

Mr. Wahlman has been an active member of the Finnish crypto community since 2017, including being a member of Suomen Kryptovaluuttayhdistys Konsensus ry (vice-president 2022–2023) and the Finnish Bitcoin Association. He has also written articles about Bitcoin for the Finnish investment magazine Viisas Raha, and worked as a Bitcoin educator.

This passion for Bitcoin is what inspired the idea behind his BTC T-shirts. He wanted to create something fun, meaningful, and wearable — for people who truly understands the Bitcoin revolution.
