Ledger: currently manages about 20% of the world's crypto assets, worth about $400 billion

Hardware wallet maker Ledger has sold more than 7 million devices and now manages about 20% of the world's crypto assets, worth about $400 billion, according to Forbes. As the price of bitcoin climbed from $68,000 to $98,000, Ledger's hardware sales tripled and transactions on its Ledger Live app surged 3.5 times, according to CEO Pascal Gauthier, who said the company is expanding from cryptocurrency security to the broader field of cybersecurity. The Security Key app, launched in September, has entered the authentication market, which is expected to reach $40 billion by 2030.

Ledger has closed a total of $600 million in funding, including a $380 million Series C valued at $1.5 billion in 2021 and an additional $108 million in early 2023 at the same valuation. The company says it is already profitable and is on track to reach $1 billion in cumulative ten-year revenues.
