When you think product lifecycle - what gaps in tools / resources / education do you think are the largest?

We built ProductHQ ( https://producthq.io ) which is product management focused and are now looking at a wider scope of product lifecycle management to see what gaps exist in tools or resources.

Would love to hear your thoughts on what tool gaps exist in the product stack or resources / education / services within the product lifecycle management world to add into our brainstorming.

Thanks for any feedback or thoughts on the topic!
