Investor in promising growth companies
As part of my business model, to align incentives and build a mutual partnership, I always prefer to hold some stake in the select growth companies I work with.
Investments through sweat equity and directly
Most frequently, it is done by offering reduced compensation for my work in return for equity. Equity can represent a significant part of my compensation - as decided on a case-by-case basis.
I have also completed direct financial investments when holding an active role in a company. Presently, I have one such investment.
Note however that I am not an accredited investor and do not complete pure financial investments without an operational involvement in the founding team.
Strategic and operational contributor
My preference goes towards deep, meaningful involvement in a company as opposed to one-off projects across a large number of them.
Mutual trust is best built over operational tasks
That's as a full business stakeholder and shareholder - not a provider or a consultant - that I make the most significant contributions.
In companies where such involvement occurs, I ultimately strive to take an active operational role and influence the strategic direction.
In my observation, the most effective partnerships start small, with a collaboration focused on some concrete outcome, and grow from there.
So I suggest helping you first with some practical business task, and then letting our collaboration take shape through increasing commitments and responsibilities.
