Why StackinSat is evolving

When we created StackinSat in 2020, our ambition was simple: to let everyone save in Bitcoin easily and for the long term.

Since then, Bitcoin has evolved. So have our clients.

Their needs have diversified, their projects have grown and their wealth has taken shape.

Today, StackinSat is evolving in turn to support this new stage.

Our convictions remain the same.
Our ambition is growing.

We stay true to our mission: making Bitcoin accessible, secure and useful for building solid, long-term wealth.

Jonathan Herscovici and Josselin Tonnellier, co-founders of StackinSat

Since 2020, we've been building StackinSat on one simple conviction: Bitcoin is an extraordinary tool for building long-term wealth.

From day one, we chose to focus exclusively on Bitcoin, to encourage self-custody and to support our clients with transparency.

Today, that conviction remains intact.

The new platform marks a new step.

Not a change of direction.

“We build StackinSat the way we invest in Bitcoin: with patience, rigour and a long-term vision.”

You set up an automatic transfer (weekly for me) and provide the Bitcoin address, and then you no longer have to worry about it! I have been using this service for a year and a half and everything works perfectly.

Easy and safe! As the holder of a PEB since 2021, I chose StackinSat for its AMF registration, reasonable fees and the fact that you keep 100% control over the storage of your BTC. Finally, it is a French company, which makes setting up transfers easier.
