(i've helped a lot of startups in my time; the story sounds vaguely correct. certainly i've seen the "we're in, we're out" dance plenty of times.)
To avoid the "we're in, we're out" scenario would it be possible to ask investors to sign a commitment agreement when they agree they're in?
E.g. an investor says they're in for $100k. You then ask them to sign a commitment agreement that states when they change their mind they owe you 10% of the proposed investment, or something like that.
Would this weed out the wanna be investors and guys who are tip toeing around so they can stop wasting your time?
That's for actual commitments. Investors historically have a very diverse vocabulary of ways to phrase "No" (for example, any sentence which begins with "I will invest if" means "No, but I like option value, particularly when it is free.") and entrepreneurs historically have a reality distortion field where they hear "No" and think "I didn't hear Never so that's practically a Yes!"
Think of it like dating. You'll get a lot fewer dates if you ask someone to commit to a series of four dates as a condition of accepting the first.
It's how it is done. That's it.
No. I don't seem to think that, at all.
Let me explain it again, just for you.
A common problem for startups seems to be dealing with investors who say they're in and a week later they're out and then later they're in again and then out, etc.
As a start up you'd like "commitment" from an investor because if an investor claims they're in and then they're out, it would be immensely frustrating right? It means you can't commit to hiring that great developer or rent that office space you so desperately need or pay yourself some salary for a change.
You might have met with an investor a few times and at some point they "say" they are very interested and they'd like to invest $100k in your idea. If you then explain to them that you'd like them to sign a commitment agreement to see how serious they actually are. If they sign it they can still change their minds, it will just cost them x% of the proposed investment. If they are not willing to sign it might just show that they're not actually interested after all, they just like to keep you around just in case something else falls through.
It's just business right?
Suggesting "A "no" is significantly better than a "contingent yes"" is bizarre.
