From Just Mining to Meria Building a Regulated Crypto Business

In May 2017, Simonin co-founded Just Mining with his brother William to make crypto mining and staking more accessible. 

The company quickly expanded, eventually rebranding to Meria. This wasn’t just a name change Meria secured the PSAN license (Prestataire de Services sur Actifs Numériques), which officially recognizes it as a regulated financial institution in France.

Today, Meria manages more than €300 million in client assets, offering staking, yield generation, and managed investment services in the cryptocurrency space. The PSAN license is a stamp of credibility, especially in a sector often criticized for lacking oversight.

Simonin also co-founded Deskoin in 2018, a crypto exchange that later partnered with Global POS to enable cryptocurrency payments at over 25,000 retail points across France bridging the gap between digital and real-world spending.

Then there’s Hash Consulting, launched in 2019 in Luxembourg, providing strategic, marketing, and communication support for blockchain projects. 

While it faced scrutiny from French tax authorities in 2025 over alleged aggressive tax planning, it highlights Simonin’s wide-reaching influence in crypto services.

Regulatory Success and Legal Hurdles

Regulation is often the make-or-break factor for crypto companies, and Simonin has navigated it skillfully. Meria’s early PSAN license acquisition placed it among the first regulated crypto service providers in France, signaling government confidence in its operations.

However, not all has been smooth. Hash Consulting’s Luxembourg base triggered a French tax investigation in 2025 over suspected aggressive tax strategies. 

While this raised questions, it also underscores the challenges of operating in a global industry where laws vary from one jurisdiction to another.

The situation reflects the balancing act many crypto entrepreneurs face innovating and expanding while staying compliant in multiple markets.
