Answer in days
A fast no is worth more than a slow maybe.
Because a slow maybe costs a founder a month they can't get back.
Investing a company's own capital changes the incentives completely. There's no fund to deploy before a deadline, no outside investors expecting activity, and no fee earned on anything other than the business actually doing well.
It also sets hard limits we're happy to state. Taking money from other people to invest, or advising anyone on their investments, is regulated activity requiring FCA authorisation. We have neither the authorisation nor the intention, so we do neither.
What's left is straightforward: read proposals properly, answer within days, examine the few that fit in real detail, and then put in time as well as capital. Anyone who asks a founder for a fee in exchange for consideration is running a different business entirely.
A fast no is worth more than a slow maybe.
Founders should keep running their company.
So no advice, no funds, no promotions.
