Has anyone tried Internet Business Mastery Academy?

Yes! I was an academy member! I took the charter option not the lifetime membership.

The material is good - but it is quite concise. All I mean by this is that you do not get TONS of stuff each month - but on questioning them about this, they said it was because they didn't want us spending all our time reading and listening to audio, so they had gone for what they consider the best balance of the two. Which is fair enough. You tend to get a few audio files, some worksheet type pdfs and videos.

The monthly modules that unlock are only half the story though - there are lots of other sections: overviews of various business/success books, a huge list of resources, Grill the Guru interviews (some are really valuable) - often 45min audio files, member Q&A sessions that can be over an hour too.

I didn't encounter any bad or worthless material in the academy. The forums were quieter than I'd hoped though, and I didn't really connect with anyone on them. Again I asked about this and most people just said they were too busy to be chatting all the time

There are soft upsells - more expensive packages that i didn't try, but they don't whack you over the head with them.

I stopped after about 4 months, roughly halfway through at the time - partly because we had babies (twins!) on the way and I couldn't justify the money each month, and partly because I wanted to put what I'd learned into practice.

I would recommend it as there is good stuff in there - however if you go for the monthly option be prepared for the first couple of modules to be basic.

If you can happily afford the lifetime membership, i'd say go for it - even ignoring the actual academy, the other resources are worth the money. If I have the money spare any time soon I'll probably grab the lifetime membership just for a good quality resource to fall back on.

I was there about a year ago and I still go back to the material I downloaded and find new, useful info in there.

I may be wrong about the refund, but I believe the way that works is that after 90 days you can buy the lifetime membership at a reduced price...that was the only thing I felt was slightly misleading as it was made to seem like you could get a full refund end-of-story (I didn't ask for a refund), but i'd like to add again that I don't know if I'm 100% correct about this, or if it is still the same - you can often get a reply from them on facebook within hours so you can always ask!

Aside from that quibble, I never experienced anything shady or misleading from them - and the material is quality. And they are on top of their customer service too!
