@killcommander666 and everyone else interested: There is a formula for the all time cash needed to earn a specific number of investors: [desired_investors^2 * 10^13 / 225 = needed_all_time_cash_earned]. Example: 10 trillion investors will need 10e12^2*10^13/225=4.444e36 all time cash. That is 4.444 undecillion. I cannot confirm this anymore since i've already bought stuff for investors.
Oh man, please let us know why! We don't mind the down votes, but if we don't know what happened, we can't fix it. Was it taking down the leaderboards? Did you lose your progress (because we can help you recover it!)? Let us know - even if you leave the 1/5 standing, we'd be happy to jump on any problems you're having.
Needs no program. Start Excel or OOCalc. Put 1.07 in C1, 4/1.07 in C2, 0 in A3, 25 in B3. Last two is the range you want to sum, you can change this to your liking. Now put the formula in C3: =(C$2*C$1^$A3)*(1-C$1^($B3-$A3))/(1-C$1) and complete multipliers and starting costs to the right, ranges downwards, fill up with the formula from C3.
At about 3.7 billion investors i can get everything to 400 quickly, lemonade, oil and bank to 500. but now progress is barely visible. We need more upgrades and achievements.
Summed up costs in steps of 100, each from lemonade to oil comp:

Credit where it's due - your comment is one of several that's making me test a new upgrade. Fun is my goal, and I WILL ACHIEVE IT!
