Swepay builds financial infrastructure for Brazilian fintechs, starting with trust. Our APIs deliver the identity, certificate, and authentication layers regulated fintechs use to authenticate B2B partners and ship products, without stitching multiple vendors together with glue code. Available now: CA Manager, a REST API to issue, renew, and revoke mTLS certificates for B2B partner authentication, with managed CRL and OCSP and an audit log included. Cloud-native infrastructure in sa-east-1, with data residency by default.
