1. Paysera. European bank account with free wire transfers. I use it both for personal use and for the companies. The great part about Paysera is that You need only name and iban to make a wire transfer in Europe and for private persons you can make 30 transfer per month for free. Cons: the app experience is very bad – i use only desktop.
2. Revolut. Best prepaid bank card. You download the app, i order a free mastercard. They offer free currency exchange all over the world. Thailand and Russia they put a small margin. This service is also very good for bill splitting or paying nanny. (I am investor in Revolut)
3. Interactive Brokers. One of the best and cheapest stock brokers. Has all the worlds markets and best rates. Also 64 ETFs that you can trade for free. (review)
4. InRento – I am moving all my p2p investments to this platform (I am investor and co-founder)
