Or in founder Ozzie Gooen's words, "a spreadsheet for things that aren't certain." Rather than a thick stack of Excel tabs with Solver, Guesstimate offers a simplified Monte Carlo simulation in your browser.I ran through a quick example that nerd parents will appreciate: How long does it take to get your child ready for preschool? In my case, about 120 minutes based upon 17 metrics. Spookily accurate.Feel free to enter your own value ranges in my test simulation, or browse other public models here.

Amidst it, I was bemused to see that my last 500 Women lightning talk had inspired this Medium article from Deema Tamimi...on ponytails.

Nothing says “CEO” to an investor like fidgeting with your hair, earrings, etc. You don’t want us to pay attention to anything besides your pitch.Or like your mama used to say, "keep your hands away from your face."Second: Numerous studies show that for women, playing with hair is a common “preening” gesture to demonstrate sexual interest. Or it’s a nervous twitch. Neither screams "I'm a winning founder", and I imagine most women would be horrified to realize they sent either signal during a pitch. Body language reactions are almost impossible to change, so just remove the variable. If your hair is out of your unconscious reach, then you eliminate the risk of female-centric messaging that hurts your chance at funding.When all is said and done, here's my advice for entrepreneurial ladies: if your hairline is high and back enough to keep your hair out of your face; if you don't fid
