Microbiome is the ecosystem of bacteria that lives within us, which outnumber the number of human cells 10-to-1. Microbes in the microbiome perform functions such as digesting food and synthesizing vitamins and have also been linked to human mood and behavior.

Y Combinator-backed biotech startup uBiome wants to generate data and research from results of learning about the microbes in our bodies. The company, which raised $351,193 of its $100,000 Indiegogo campaign last year, offers three different swab site kits, with which people collect a sample, insert it in a tube and ship it back.

uBiome raised $1.5 million from angel investors and $3 million from Andreessen Horowitz.
