Bill Gates is funding a startup that's working to replace eggs.
The new company is working out of a garage-like space in San Francisco's South of Market neighborhood.
Research chefs with Hampton Creek Foods are baking cookies, cakes, making flavored mayonnaise, French toast and omelets... all without eggs.
A lot of big Silicon Valley investors are putting money in, the most prominent of which is Bill Gates.
The company is now selling its first product, called Just Mayo mayonnaise, at Whole Foods.
Hampton Creek Foods says its mission is to disrupt a global egg industry that wastes energy, pollutes the environment and is cruel to chickens.
