9 tips to help crypto companies choose and succeed with a banking partner

expert panel

Before reaching out to a potential banking partner, it’s wise to know both what they can offer and what they’ll expect. Choosing the right banking partner can be a particularly tricky process for a crypto or blockchain company. While there are many options in the market, only a few will possess the experience, commitment and risk tolerance companies in a young and tech-forward industry need. And simply making a choice won’t seal the deal: Crypto and blockchain entrepreneurs must have the detailed information banks will demand at their fingertips and be ready to reciprocate the transparency they themselves expect from a financial partner. There’s a lot of homework to be done before beginning any sort of outreach, so knowing what to look for as you begin the research is a helpful head start. Below, nine members of Cointelegraph Innovation Circle share their advice for crypto and blockchain companies that are beginning the process of choosing a banking partner.

expert panel

Traditional companies and investors may know the business fundamentals and financial metrics to examine but be unclear on industry-specific “must-haves” such as necessary tech capabilities and a committed fan base. Industry insiders, on the other hand, may be impressed by a potential partner’s community presence and the features they promote but overlook the health of the financial and advisory foundations.    To ensure a profitable partnership that brings value to both parties and to end-users, it’s essential to examine both the big picture and the telling details. Below, 17 members of Cointelegraph Innovation Circle share tips for companies and individuals engaged in evaluating a potential Web3 partnership.
