Statements from this episode (16)
Ralston: Typical angel check sizes range from tens to hundreds of thousands
“It sort of tends to be a minimum in the tens of thousands of dollars, up to a maximum of, you know, hundreds of thousands of dollars, usually.”
Ralston: Founder resilience and belief matter more than market size, capital, or intelligence
“You know that if you don't have the resilience you need, the toughness you need, the determination you need, the belief you need, it, none of the other things matter. Nothing else. How big the opportunity is, how much of competition there is or isn't, how much…”
Ralston: Angel investors mostly have marginal or minimal impact on startups
“Angel investors can, in limited cases, have substantive impact on the companies in which they invest. Mostly their impact is marginal, minimum.”
Ralston: First-time angels must calibrate by meeting multiple startups before investing
“But it is true in the very beginning, before you've made your first angel investment, calibrate. So do spend, I don't know if it's a hundred or 10 or 15, you should.”
Ralston: Angel investments should default to zero value until proven otherwise
“You have to be prepared to zero out that investment. In fact, you know, my default position when I invest in a startup is that that investment is not worth zero. It's not like if I put, pick a number, 25,000 dollars in a company, And then I track that. Its val…”
Ralston: Combining Early Stage and Growth Investing in One Fund Is a Bad Idea
“VC started doing both early stage and growth, sometimes in the same fund, strangely, which I don't necessarily think is a great idea.”
Ralston: Startups Are Raising as Much Money in ICOs as Traditional VC
“Radical in that, like so early, there's an equal amount of money in ICOs being raised by startups as venture money.”
Ralston: The Startup ICO Fundraising Boom Is Not Sustainable
“Don't really believe it's sustainable.”
Ralston: Angel Investors Without Deal Flow Will Take the First Pitch
“You need deal flow. Find a way to get deal flow. We'll talk about that. If you don't have deal flow, you'll take the first thing you get.”
Ralston: Angel Investing Is a Game of Big Wins, Not 7.6% Returns
“Because when you're angel investing, if you're going for a 7.6% return to try to beat the stock market, you're in the wrong game. Right? It's a game of big wins.”
Ralston: Mistreating Failing Founders Destroys Deal Flow and Returns
“In fact, if you think about it, if you act like a jerk to a founder, that might be, even if that gets you an extra 50% of your return, your investment back somehow, That might actually cost you way more in the long term because the way you get deal flow is bec…”
Ralston: Most angel investors do not get into later rounds
“The fact is most angel investors don't get a bite at the later rounds.”
Ralston: Conditioning angel checks on round completion makes investors useless
“Don't try to be the last money in because you don't have any confidence in yourself. So some of the worst investor behavior is to say, Craig, I like you. I like your company. You're raising a million dollars. I'll put a 100,000 dollars in as soon as you raise …”
