Services/consulting doesn't get "funded" the way product does the funding is your first few clients. Cash flow is the seed round. Sounds glib but it changes everything: you optimize for getting paid fast, not for a fundable narrative.
On "go deep in one thing" it's right, but people hear it wrong. It's not "only offer one service," it's "be the obvious person for one specific buyer with one painful problem." Depth in who, not just what.
And yeah AI makes the front-end trivial, which is exactly why the build stopped being the moat. The moat now is distribution and trust: can you actually reach the buyer, and do they believe you. That's the part AI didn't commoditize.
