Meet the engineer who sold his company for almost 200 million and used the money to open a chocolate factory in San Francisco

When Todd Masonis and his partner sold their startup to Comcast in 2008 for a rumored sum between $150 and $170 million, he took a "fun year."

Masonis, a Stanford grad, excavated a Roman fort in England, biked across Scotland, and toured family-run chocolate factories in France.

It was in France where something clicked for the serial entrepreneur. He returned to the US and cofounded Dandelion Chocolate, a small-batch, bean-to-bar chocolate maker in - where else - a garage.

Step inside Dandelion Chocolate, located at 740 Valencia St., in San Francisco's Mission District, to see how Masonis and his team are disrupting the sweets industry.
