And if you can raise $100k, you can almost certainly raise 150.
With the oncoming recession and all, you do want to have enough in the bank for at least 1 to 2 years, if you are serious about your startup.
Also, I'm not sure what to make of your comment "Two strong hackers, working for 6 months is eaily $140K expenses" How good the hackers is hardly related to the expenses they require. Perhaps 140k is the opportunity cost?
Having enough in the bank for 1-2 years is probably a good idea, but it sounds like they could do that on $250k-$350k.
Also, I agree with matt, focus on the percentage you are giving away rather than the amount you want to take.
If you look around you may find a business partner who could give you some money as part of some kind of deal. Traditional software companies can do this by pre-selling licenses at a discount and web companies looking for ways to get more users may pay you if you find a way to help your users get signed up with them. However I'd caution against spending too much time on this sort of thing yourself as it can easily become a distraction.
If you need 100k, why are you looking for VC funding? They will give a horrible valuation and take a large part of your company. First phase funding in the ~100k range I would look for angel investors or get the people involved to contribute the money. Either raise 500k from a VC and have a much more aggressive growth strategy if that is the route you want to go, or raise 50k from friends/angels/yourselves and minimize costs as much as possible.
(friday night, beer and a looming all nighter...and other excuses, read the YC as VC...)
