For five years, we’ve published our Fintech 50 list, highlighting the top private companies that are reinventing finance through technology. (Here’s last year’s list.) From buy now, pay later lenders to payments startups making money flow faster, these businesses are dramatically improving the cost, efficiency and access of financial services.

We’re updating the list for the sixth year, a months-long process that involves a team of ten reporters and editors. We divide the work into fintech subcategories, speak with industry investors, analysts, entrepreneurs and executives, evaluate hundreds of companies and ultimately choose 50.

We need your help with nominations. What companies deserve to make the list, and why? The more you can share about their growth, including revenue over the past two years, the more likely you’ll get our attention. Please read our methodology below and see the end of this article for the link to the nomination form.
