FAQs

Things prospects ask

Is alumni revenue real?

Yes — across our book it averages £4.1M ARR per 1,000 alumni in year two. We share the methodology under NDA.

Do you handle exits?

We design dignified exits as the entry to the alumni network. The way someone leaves predicts the revenue they send back.
