What startups do with Olympus.

Bank the business

A business account and team access from day one.

Accept payments

Payment links and QR codes need no integration to start.

Issue cards

Virtual cards for tools and contractors, with limits.

Build on the API

Sandbox keys let engineering start before the business is verified.

Embed financial services

Offer your users accounts, payments, payouts and splits.

Operate the back office

Statements, reconciliation and approvals as you hire.

A typical path.

Day one
Open the business account and invite a co-founder as Admin.
First customers
Send payment links and invoices. No engineering needed.
First hires
Add Members and Viewers; turn on approval thresholds for larger payments.
First integration
Create a sandbox key, register a webhook, and connect checkout to your product.
Scale
Split payments to recipients, bulk payouts, and embedded flows.

Engineers can start on day one.

Sandbox keys work like live ones without touching a real processor, so a product team can build and test the whole flow while the business completes verification.
