im a senior product leader at a successful saas post-IPO company that used "simon kucher" (author's employer), and specifically had the author as the lead consultant.
the work they did was "fine", but hardly earth shattering: they recommended effectively what we already knew we needed to do but leadership was too afriad to do. so the board convinced the c-levels to spend $500k+ on these consultants to effectively validate the findings.
pro tip: strong product leaders already have a really good idea what the pricing model should be. you dont have to spend a fortune to have someone unfamiliar with your business and market tell you.
[edit: technically Madhavan isnt the author but i dont really know who is]
