Grandpa Frank

Come in. Tell me what you're building.

I'll look it over and tell you straight whether the idea, or the next chapter of your startup, is worth the next stretch of time and money.

Free for founders. Investors: free during early access.

Have a seat. Here's how this goes.

You talk. I look. Then I answer, in plain English, with a score and what I'd do next.

1
Tell me where you are
A new idea or a company already in market. Who it's for, and how far along you are.
2
I look it over
Customers, similar businesses, funding, and how demand might unfold if your assumptions hold.
3
I write you a report
A grade, strengths, risks, and the questions I still need you to answer.
4
You decide who else sees it
Keep it private, share with a co-founder, or put it on my desk for investors.

Bring me the idea or the company you already started. I'll tell you what I see, without hiring a research team.

Browse what I've already reviewed, strongest first. Open my notes, then message the founder if it still interests you.

Same desk, same order. No surprises about the method. Plenty of honesty about the answer.

1
Customers
Who is most likely to care, and who probably will not.
2
The path
How interest, sales, and growth might play out if your numbers are right.
3
The neighborhood
Similar businesses, and what their stories suggest for yours.
4
The money
What you may need, for how long, and for what, at this stage.
5
My answer
A grade, the risks I won't ignore, and what to do this week.
