FORBES - July 23 - Instant Chemistry helps couples understand the science behind their attraction. The site was founded in 2013 by Ron Gonzalez, who has a PhD in neuroscience. In the early days, Instant Chemistry worked with a dating site Singledout. They ended this partnership 8 months later. Gonzales doesn't regret. He received several emails from couples asking if they could use his test to determine whether they are a good match. Instant Chemistry’s kit tests for three Human Leukocyte Antigen (HLA) immune system genes and four behavioral genetic variants. It also includes a psychological assessment. Although the market for DNA testing for love hasn’t yet been proven, Instant Chemistry’s growing customer base gives Gonzalez high hopes.
