I got in touch with the founder of Plato when they were just starting out. I was trying to learn how I could become a better manager and was paired up with someone from Airbnb. I remember having a good experience.

They are tacking a hard issue of dealing with people. There are many great engineers who write great code but when they are then promoted for their efforts into a leadership role they struggle. Everyone is afraid of asking stupid questions and Plato is creating a place that allows for great engineers and tech leaders to speak to others who have been in their shoes before - not to mention allow for networking capabilities beyond just LinkedIn!

Birdly has a great user interface and it makes it very easy to use.They have an amazing customer support , they are very quick and provides the right solution.
