I invest in many of Ashcroft's deals, and know Joe personally. Can't speak highly enough.
Joe Fairless is as legit, genuine, and passionate a person as you will ever come across. That is reflected in Ashcroft. That also comes through in his books, his podcast, and especially at his Best Ever conference, which is top notch.
@Sanjay Patel they can find those deals because they have a good sized team of talented people in smartly defined roles under a highly effective org structure, they are armed with data, they work their butts off, and they are extremely creative and strategic in their negotiations. Deals that would be mediocre for other GP's could be great deals for them based on their ability to buy smarter and add more value for less money.
For anyone who's on the fence, you could get yourself an early bird ticket to his 2021 Best Ever conference and meet him and his team in person. Aside from a ton of great content and networking, it could serve as a powerful step in your diligence process.
