Our take

Frustrated by the archaic, fee-laden banking services offered to entrepreneurs, the founders of Mercury set out to create a better solution. They envisioned a platform that was dynamic, tech-driven, and free from unnecessary fees.

Mercury delivers on this vision by automating business payment processes, offering FDIC-insured accounts, and providing full API access, empowering entrepreneurs with greater control and efficiency. This approach stands in stark contrast to traditional startup banking, which often burdens young businesses with high fees and limited functionality.

By prioritizing user experience and offering a free service tier, Mercury has attracted over 200,000 businesses and achieved a $3.5B valuation as of 2025. As a rising unicorn in the stagnant world of startup banking, mercury is backed by substantial funding and poised for continued growth, constantly adding new features and expanding its team to further disrupt the industry.
