Hold out to at least show your investors a bit of growth, even 20% more would be a huge return annualized (if you've only held it a couple of months). I would also want to pay myself my opportunity cost in lost wages.

If they're a big firm and they want into your established and competitive industry, you're the cheapest and safest way in, so remember you have a lot of bargaining power.
