The Intent
You want capital, but you do not want to lose control or future upside by agreeing to a poorly structured deal.
How I Solve It
I determine enterprise value using the 25 Factors, then assess how new capital changes Risk, Opportunity, and Return on Investment. These factors are central:
- Factor #4: Return on Investment (ROI)
- Factor #11: Future Outlook
- Factor #21: Minority Interest
- Factor #22: Special Interest Purchaser
The 5 Senses Inspection Report helps determine whether the investor will be a passive capital provider or an operational influence, which materially affects value.
Experience
It matters because “What percentage should I give an investor?” is really asking “How much of my business is this money truly worth?” and that depends entirely on having a realistic, experience‑grounded valuation, not a guess or a rule of thumb.
Why the gut–brain axis is central here
On paper, the percentage is just math:
equity % = investment / post‑money valuation.
But the hard part is the valuation itself. A 1M cheque at a 4M pre‑money is 20%; at a 1.5M pre‑money it is 40%. The only difference is what you say the business is worth.
That is where 10–15 years of owner‑operator “gut–brain axis” experience becomes critical:
- It lets the valuator separate owner‑dependent goodwill (which investors are rightly skeptical of) from enterprise goodwill, systems, and intangible assets that a new owner or future buyer can actually rely on.
- It brings pattern recognition about what similar businesses, with similar cash flow and risk, actually clear the market for, so your valuation is anchored in reality, not wishful thinking.
- It translates messy, real‑world factors management depth, customer concentration, competitive moat, scalability into a defensible valuation range investors recognize as fair.
How this changes “What percentage should I give?”
Without that seasoned valuation:
- You might give too much equity for too little cash because you undervalue your intangible assets and growth, permanently over‑diluting founders early.
- Or you might ask too much valuation, offer too little equity, and repel serious investors who see the risk and know the market comps.
With a serious, experience‑driven valuation (like the FMV work you tie to your Experience page and 25‑Factor / 5‑Senses framework), the percentage you give an investor becomes:
- A direct consequence of a well‑reasoned value for the business today.
- A conscious trade‑off between dilution now and future rounds, modelled in a way that investors and you can trust.
So the reason your 10–15‑year owner‑operator requirement is so important to “What percentage should I give an investor?” is that the equity slice is only as good as the valuation underneath it, and producing a valuation that both protects the founder and satisfies professional investors is exactly the kind of high‑stakes judgment that demands a fully developed gut–brain axis.
Experience reveals that the wrong investor can destroy more value than they contribute. This insight comes from years of observing post-investment dynamics, not from deal theory. Understanding how ownership percentages translate into real control requires lived experience. See my Experience link.
The Result
You arrive at an equity structure that reflects true economic contribution and preserves long-term value.
