Without a marketing budget, Smith and Bhambra had to identify cost-effective ways to market nOCD. They focused on using social media to build an OCD awareness movement that would generate enough buzz to encourage people to download the nOCD app. Smith and Bhambra also sent a semi-weekly email newsletter to two different audiences: clinicians and nOCD patients. Inside each email were deep links for downloading the nOCD app. These deep links showed where the download originated, allowing Smith and Bhambra to gauge the effectiveness of Facebook, Instagram, Twitter, Reddit, the nOCD website, and their newsletter.

Smith and Bhambra applied some sophisticated statistics that Smith was learning at Pomona to data on over 60 different social media variables collected over a 108-day period in 2017. They used half the data to try different model specifications and then used the other half to test their model.

Smith and Bhambra were able to avoid many data science pitfalls, but they did make a few mistakes. For example, they initially collected data once a week, which made the day of the week a confounding factor. They had to start over and collect new data from scratch. But if it weren’t for the lessons learned from their early mistakes, they wouldn’t have been able to create the model that led them to success.

After class Friday, Smith would often drive his 2003 Toyota Sequoia to hospitals and medical conferences to publicize nOCD. During one cash squeeze, Smith drove 400 miles to San Francisco to sneak into a mental health conference. He found a customer—one customer, but it was enough to keep the servers running—which kept the company running.

One night, shortly after Smith moved into his Pomona dorm room to start his senior year, the team unexpectedly received a surge of traffic at 3 a.m. while they were sleeping. When they woke up, the servers were down, because thousands of people from the United Kingdom had attempted to join nOCD and crashed the servers. How did this happen? An OCD specialist from the Britain went on a show called This Morning, the British equivalent of Good Morning America, and gave a persuasive testimonial about nOCD’s efficacy in helping her practice. Since the nOCD team had a premium server package, they were able to get immediate customer support and get their servers back up the same day. They now knew firsthand that cash is critical for dealing with the unexpected problems that come with growth.

Smith closed his first major contract with a company that wanted to use the nOCD data to study the effectiveness of different OCD treatments. While Smith was finishing his last semester at Pomona, nOCD secured $1 million in financing, which allowed the nOCD team to build and market an even more sophisticated product.

Since then, nOCD has grown rapidly, and is now the world’s largest OCD treatment community, helping people in over 100 countries. They’ve also revolutionized the way research is conducted on OCD. While patients may be unwilling to speak candidly with therapists and often have
