Ask HN: How to brainstorm a product name in 2 days?

We are launching a new SaaS platform in January. We realized yesterday that there is a risk of confusion with a well established brand here in France.

We need to change our brand name as quickly as possible.

Our app will help french private practicioners in their daily tasks (appointments, consultations, invoices etc.).

Any advice on how to brainstorm for a product name would be really helpful right now...
