Why Paycux for Startups

Built for the stage you are actually at

Small teams do not have a spare quarter for identity plumbing. Every decision below exists to keep that quarter yours.

Future-proof and modular

Every Paycux product works standalone. Whether you need AuthKit for basic login or Enterprise SSO for a more mature customer, you pick and choose based on what the deal actually requires.

Easy-to-use APIs

A single, elegant interface with modern APIs means you integrate in minutes. SDKs cover the platforms you already ship on, and the docs are comprehensive without being a maze.

Designed for B2B SaaS

Paycux natively models organizations, removing the complexity of handling the users-to-teams relationship inside your authentication and authorization layers.

Transparent pricing

High costs, low usage caps and opaque pricing are the standard complaints about auth vendors. Paycux prices per connection, and what you will pay is agreed with you up front.

Integrate in minutes

Client libraries for the platforms you already use, a staging environment at no cost, and an example app you can clone before you commit to anything.

Integrate in minutes

One install, then the API you expected

Client libraries for the platforms you already use. Point sign-in at Paycux in staging, ship it when the tests pass, and keep the rest of your codebase untouched.
