Speaking as a founder who is putting both sweat and cash equity into their company: run, don&#x27;t walk, from cofounders that demand not to have a cliff. You might not end up regretting giving someone a pass on their vesting cliff, but if you do regret it, <i>you will regret it a lot</i>.<p>If you&#x27;re part of a founding team and you put cash in, get IOUs, and take cash back out later.
