IA is part of it, but the I would say the broader term for the field is "Knowledge Management".

https://en.wikipedia.org/wiki/Knowledge_management

Also related is the field of "Organizational Learning".

https://en.wikipedia.org/wiki/Organizational_learning

It's a huge topic, and would be hard to do justice to in a HN post.

There are a lot of good books on the topic. A few I'd recommend include:

https://www.amazon.com/Handbook-Organizational-Learning-Know...

https://www.amazon.com/Wellsprings-Knowledge-Building-Sustai...

https://www.amazon.com/Winning-Knowledge-Transfer-Michael-En...

https://www.amazon.com/Only-Knew-What-Know-Knowledge/dp/1451...

https://www.amazon.com/New-Edge-Knowledge-Management-Changin...

https://www.amazon.com/Fifth-Discipline-Practice-Learning-Or...

Hmm... a few that jump to mind for me would be:

The Art of the Start - Guy Kawasaki http://www.amazon.com/Art-Start-Time-Tested-Battle-Hardened-...

Outside Innovation - Patricia Seybold http://www.amazon.com/Outside-Innovation-Customers-Co-Design...

Unleashing the Killer App - Larry Downes & Chunka Mui http://www.amazon.com/Unleashing-Killer-App-Strategies-Domin...

Wellsprings of Knowledge - Dorothy Leonard Barton http://www.amazon.com/Wellsprings-Knowledge-Building-Sustain...

The Innovators Dilemma - Clayton Christensen http://www.amazon.com/Innovators-Dilemma-Revolutionary-Busin...

Crossing the Chasm - Geoffrey A. Moore http://www.amazon.com/Crossing-Chasm-Geoffrey-Moore/dp/00605...

The Startup Game: Inside the Partnership between Venture Capitalists and Entrepreneurs - William H. Draper http://www.amazon.com/Startup-Game-Partnership-Capitalists-E...

Some of these aren't necessarily about startups, but I think they all have something valuable to offer. YMMV.
