About Sunlight (YC S22)

Sunlight (YC S22), a startup founded in 2021, is at the forefront of transforming B2B payment infrastructures. Its core proposition lies in enabling platforms to transform missed card opportunities into tangible revenue through a sophisticated API designed to handle the execution layer of card payments.

Traditionally, banks and fintech entities have depended heavily on ACH and checks, often bypassing card-based transactions due to complexities in execution across various payment systems. Sunlight addresses this pain point by leveraging AI to complete these payments seamlessly, thereby enhancing card volume, increasing take rates, and generating scalable payment revenue without additional manpower.

The company received a Pre Seed Round investment on 12 September 2022, with backing from prominent investors such as Y Combinator, Liquid 2 Ventures, and LombardStreet Ventures. This positioning within the API, B2B, and Fintech space highlights its potential to redefine payment processing for its clientele.
