Write the no first
Thresholds set before money is spent.
Because starting is exciting, closing is embarrassing, and nobody writes down what a no looks like.
The useful discipline is cheap and almost never done: before spending anything, write down what result would mean stop. Once money and pride are committed, every ambiguous number reads as encouraging, and a venture can absorb years on that basis.
Funding is the opposite problem. Having decided to proceed, under-funding a launch to spread capital across more ideas produces several businesses that each lack what they needed. One properly resourced beats three starved.
Then there is closing. A business making a small profit while consuming most of the management attention is a worse outcome than a clean shutdown, and recognising that annually — in writing, against what was expected — is the whole job of a parent company.
Thresholds set before money is spent.
Starved launches fail expensively.
No outside funds, no securities, no advice.
A first conversation, with a quick honest answer either way.
