How do you describe Soylent?
Healthy fast food.

What’s a common misconception about Soylent you’d like to clarify?
People are often pleasantly surprised that it can taste good and be nutritious, especially our new flavors. Also Soylent is not a commitment. You don’t need to give up regular food to use it. It’s just another option when you want something fast and filling.

What’s the hardest part about making a food product vs electronics?
There is more variation in biological ingredients than electronics, but we still manage to make a consistent product. Also the safety and quality controls are much more strict, as they should be.

You pivoted after YC. What were you making before?
A wireless network for small connected devices.

Why did you pivot?
Functional food meets a universal basic need and has more potential for repeat customers.

How have you found the fundraising process for a food product?
Fundraising is the worst.

Better is a friendship based on business than a business based on friendship
