Founded 2018 as 'Wise' and rebranded Solid in 2021, the company positioned itself as the 'AWS of fintech' — a BaaS layer offering banking, payments, cards, and crypto via APIs for fintechs and vertical SaaS companies. It raised ~$81M and hit a $330M valuation on the back of a $63M FTV-led Series B in August 2022. Within a year lead investor FTV sued to claw back its $61M, alleging the founders had misrepresented revenue and churn; a counter-suit followed. The business did not recover and filed Chapter 11 in April 2025, winding down to three employees — one of the clearest casualties of the 2023–2025 BaaS reckoning alongside Synapse.
