Yes, but the audience it's written for generally cares about questions like "what is the pain point you are solving for your customer?" That is one of the first questions a funder asks — and given how many funders they have lined up, presumably there is an answer.
As for pitching law firms on efficiency, that's actually an uphill battle in many ways. Lawyers bill by the hour, which means that there is not a natural demand for tools that increase efficiency. Post-recession, there is an increasing amount of fixed-fee work, which helps on this front. But the bread-and-butter for many firms (especially prestigious ones, who don't have to accommodate fixed-fee arrangements) is hourly work.
And lawyers are still ethically expected (by many state bars) to measure and log hours worked, even under fixed fees. Same with contingency fees. So let's say that a client is paying a fixed fee for work, then discovers that it's now taking half the time to do the same work. They're going to demand a lowering of their fixed fee in proportion. So even under alternative fees, there's still an incentive to keep high "hours" on the bill
