We, at retention.ai built a User uninstall intelligence platform. It took a lot of iterations and an amazing team to get it right. Retention.ai was a library for android apps that would help app-developers understand why their customers were uninstalling their apps. It was a problem as yet unsolved in the industry.
We used a complex pipeline to both identify uninstalled users and save metadata around them.
Once the metadata was collected, we trained deep neural nets to predict which of the current users was more likely to uninstall the app.
Some of the metadata that we used was -device details,user location, competing apps installed on the device, time spent per Activity etc..
The product was an instant fit for the market at the time and we were able to get apps like housing, commonfloor, carwale, haptik etc to use our lib! :)
I would like to recommend Guarented as their team has a perfect combination of strategic, technology and operational execution abilities. What interests me is their unique business model where any individual with some spare cash can become an asset owner and earn very good returns on his / her investment. I have personally known one of the co-founders - Harsh who also worked with me in Capillary. During his tenure here as a special projects manager, he has displayed excellent leadership skills and ability to connect with people. I strongly recommend the team and wish them all the best for their venture.
