Thin End of the Wedge
The secret of the thin end of the wedge is… it’s thin.
As Rick Segal suggests, ship a solution problem you can solve today, and use revenues to finance pushing the wedge in wider for the bigger solutions to bigger problems tomorrow.
Beyond immediate revenue, it gives you customers (who will be your best prospects for the next, bigger things), a track record of solving problems (which is a much stronger marketing foundation) and feedback to influence development of the “big thing”
You can “boil the ocean” - it’s just easier to do in pieces than all at once, and the most common way of getting big involves starting small.
So start, already. JSTDT.
