The Funding Game - How the First Financing Rounds Work
Fundstrapping - Exception to the norm
You might have "bought the ticket, and now you're expected to take the ride" - indefinitely until a liquidation event once you've taken the money and closed your first round, but there is a growing (IMO positive) trend of "fundstrapping" becoming a thing, aka take only one round and (you're) done (with fundraising).
However, this is something you should discuss with your co-founders first and do a plausibility check if it would be at all possible with your intended business model, your burn rate, and the speed needed for execution to succeed.
And it is most likely something you should discuss with investors up front, as an important term or expectation for you.
It most likely would also be a criteria to look for investors by, aka who's already onboard with the "fundstrapping" concept, who's done these deals before?
Also, Business Angels might be cool with the concept than VCs.
