What's the pretotype?
Greg used the Infiltrator Pretotype method to place his call to action in the massively popular Jackson Greathouse Fall’s HustleGPT thread that was blowing up. 50,000 people signed up in 40 days! That's real skin in the game.

What’s working well? What could be better?
Carefully crafting the 'would you like one?" question (which often just gives you opinions, and opinions are not data) to get someone to take the action "Reply AI to the tweet" gave Greg initial levels of interest. Smart!
What are the takeaways?
- Jump on your idea fast and find unique ways of exploring the intersection of your idea, the need you're solving, and where you can find an early adopter audience.
- Ask for skin in the game and if it's a winner, you'll know it when you see it!
In the field
I'm working with a large enterprise client that is highly motivated, well-funded and excited to run experiments and I am once again reminded of how important it is to align ideation from the product teams with staff that are in the field directly engaging with the customer, prioritising the best ideas and then rapidly testing. We're not experimenting as fast as I'd like, but the groundwork of aligning the teams so we can move fast later will allow us to experiment at pace in a few weeks.
