I did Ignite 4 years ago (when it was called Ignite 100). It was a brilliant experience, I learned a huge amount about both running a startup and myself, and we raised at the end. We subsequently failed but I don't regret anything about doing it. Ignite now runs in Newcastle, Manchester and London, and has a raft of successful startups in its network. No big exits yet as far as I know, but it's too early for that.

They're doing some innovative things too - Ignite is angel-backed now and they've just run a successful campaign on Seedrs.

Moltin did Ignite before going on to do YCombinator.

Reach out to Paul Smith who runs Ignite (@paul_a_smith on Twitter). He's a really nice chap.

I would have a look on Wayra: http://wayra.co/en/
