Business development, market assessmebt, technical development etc.

None of these firms that charge their portfolio companies are the typical valley top-tier funds, but I do not think it means that charging portfolio companies for professional services is a bad thing.

Design, legal, engineering, etc.

A16Z has a lot of in house partners that focus on things other than just investments.

Edit: Just want to say that the top funds do not charge for these services. Some funds do - they invest and then you pay them back a bunch of money for services.

This is part of the model of Playground.global, Andy Rubin's hardware-oriented VC firm, although you pay with extra equity at the common price.
