Founded in 2014, Ledger is one of the first companies to offer a hardware wallet for Cryptocurrencies. A hardware wallet is a small device (usually USB powered) that holds your private keys and can be accessed with a password. The private key is the “password” that you need in order to sign a transaction on the blockchain and manage your funds. Theoretically this means that your private keys are not stored on your computers and it is harder for hackers to steal your crypto. Ledger has two flagship products - Nano S and Ledger Blue, the former having sold more than 1 million worldwide. One special fact about Ledger is the inhouse developed OS called BOLOS, which adds an additional layer of security - hacking a secure chip is way more complicated than hacking a software. Last but not least, for Enterprise customers, Ledger offers a multi-sig software wallet with a cold-storage hardware solution that can be used to manage multiple Cryptocurrencies. The company has offices in Paris and San Francisco and is growing rapidly, currently having about 80 employees. The last funding round was in January 2018 for a total of $75 mio Series B funding.
Ledger is hiring massively both in Paris and San Francisco and they are constantly looking for specialists that are interested in working in the Crypto industry.
