Alisha you may if it is prior to a VC financing, you also can control the Board of Directors. You should know that both the Board of Directors and shareholders have a right to approve key decisions of the company. Remember that the Board decisions are made on the basis of one person, one vote rather than on a percentage of ownership, so be careful with the composition and size of your Board. The preferred stock holders will have called protective provisions which give them "veto righs" over key decisions, with this we are talking about thinks like a new round of financing or selling the corporation. Don't forget all this, sometimes thinks doesn't depend on the percentage of ownership.

How does this affect an LLC as a non inc body? Say two partners start up an LLC with un equal funding. 60/40? And what if equal funding 50/50?

The answer depends on whether the shares of stock you own in the company are voting or non-voting shares. If there is only one class of voting shares and you own more than 50% of it, then generally you "control" the company for practical purposes. There are certain decisions like mergers, dissolution, etc. which often require a "supermajority" vote, or 2/3, but these are fundamental changes that do not happen often.

To illustrate, a company may often have two classes of shares, voting common stock and preferred non-voting stock. The common stock allows the holders to vote at shareholders' meanings, but carry a right to dividends less than the preferred shareholders. The non-voting preferred shareholders have a "preference" as to dividends, but cannot vote their shares. The corporation may be composed of any number of combinations of voting and non-voting shares. If you own more than 50% of all of the outstanding classes of voting shares, then typically you will control the corporation for most decisions made by shareholders.
