Solid (Solid.fi)

Solid (formerly Wise) was a venture-backed fintech-as-a-service / embedded finance platform offering banking, card, and payment APIs to fintech builders. Solid raised more than $80M, including a 2022 Series B led by FTV Capital. The company subsequently became the subject of significant legal trouble - including litigation with FTV Capital and reported customer disputes - and substantially wound down operations through 2023-2024. As of this profile, the solidfi.com site is not responding to requests and no active API or onboarding pipeline appears to be operating. This is an honest historical record; treat any API references as unverified / inactive.
