Another possibility is to counter-offer with an offer like the following. We will sell you the IP for $XXX,XXX (USD) and 2 months of PT work from each of the founders to ease the transition. Founders will stay on 3 days a week for the first month (at a rate of $2400 a week) and then down to 2 days a week for the second month (at a rate of $1800 a week). Primary purpose will be to do finish out in-progress features, update documentation and work with employees of the acquiring firm to do hand-offs. This type of arrangement helps you hand if off and be able to put on your resume that you sold your start-up as compared to just saying that you shut it down. Second, it helps the acquiring firm to have a chance at a successful hand-off. Third, it gives you and your co-founders a transition time to look for other jobs without immediately going to zero income.
