FAQ

Frequently asked questions

Everything you need to know. Can't find an answer? Reach out to your Nimbus Account Manager.

What is full-stack mediation?

A single unified auction where every demand source bids in real time, replacing a sequential waterfall.

How long does migration take?

Most publishers complete migration in a few weeks, with white-glove support from the Nimbus team.

Will it add SDK weight?

No — the Nimbus SDK consolidates integrations, so you remove weight rather than add it.

How many demand sources does Nimbus support?

Over 60 demand partners compete in the core auction — more than any other open-marketplace partner.

Do I keep my existing direct deals?

Yes. Direct and programmatic demand run side by side with no extra setup.
