Wendy De La Rosa, the 29-year-old cofounder of Common Cents Lab, proudly recounts an experiment she ran a few years back with Digit, an app that tracks users’ spending and moves free cash from their checking account into savings.
One group of users was sent a text message in February before they got their federal tax refund, asking if they wanted to save part of it. Another got a similar text right after the refund hit their checking account. Those responding to the early message saved an average of 27%, versus 17% for those who were texted later.
When you consider the average refund is $2,900, that’s an impressive chunk of extra savings. “Every dollar that leaves our checking account, we feel that loss over and above the economic loss of that dollar. It physically hurts us to lose money,” De La Rosa explains. In other words, it’s easier to save money that you never saw in your checking account.

In 2015, De La Rosa cofounded the Common Cents Lab, a nonprofit applied-research shop that aims to help low-to-moderate-income households increase their financial wellbeing. Last year 93 companies and nonprofits applied to have their services and customers used as guinea pigs in Lab experiments. Fourteen made the cut.
So far, De La Rosa has worked with 20 fintech startups, including 4 on the Forbes 2019 Fintech 50 list: Plaid, Chime, Credit Karma and Even. “It’s a mutually beneficial relationship, where the researcher gets to research what would otherwise be impossible and we get to learn something [for free]. It’s like, why would we not?” says Even CEO Jon Schlossberg, who has raised $51 million for his startup, which offers budgeting apps and paycheck advance services through employers, most notably Walmart.
Common Cents operates under the umbrella of the Center for Advanced Hindsight at Duke University, run by the well-known behavioral scientist Dan Ariely, a Lab cofounder and also the chief behavioral officer of Lemonade. But De La Rosa works out of Palo Alto, where she’s completing a Stanford Ph.D. in consumer behavior. It’s not just the lure of free research that has would-be partners competing for her attentions. De La Rosa says she’s seen a few startups (no, she won’t name them) fail because they focused on slick technology and artificial intelligence while ignoring basic human psychology.
A self-described hustler, De La Rosa says her life has always been centered around money—or the lack thereof. At age 9, she immigrated to the U.S. from the Dominican Republic with her mother, settling into her grandmother’s small two-bedroom apartment in the Bronx along with ten other relatives. De La Rosa picked up English quickly (through school and the Cartoon Network) but had to retreat to the apartment’s one bathroom for needed quiet to finish her homework. And finish she did. She was valedictorian of her public elementary and middle schools and of Cardinal Spellman High School in the Bronx—the alma mater of Supreme Court Justice Sonia Sotomayor.
Meanwhile, De La Rosa’s mom, a psychologist in her home country, took what work she could find—as a hotel maid. “It was very hard to see your educated mom clean rooms. She sacrificed a lot because of me,” De La Rosa says. “I think that’s where I started to fall in love with financial decision-making, because when you are living in a certain circumstance where every dollar really matters, it becomes a topic of conversation.”
So De La Rosa headed off to Wharton, where she studied finance and management, graduating summa cum laude and Phi Beta Kappa in 2011. Her well-earned reward: a job at Goldman Sachs. Having grown up poor, she wanted to be able to help her family. “Working on Wall Street seemed like the easiest, fastest way to get there,’’ she says. Fast, yes, but not so satisfying for De La Rosa, who in 2014 went to work with Ariely on a new behavioral economics unit at Google. The next year, Ariely, De La Rosa and two other colleagues came up with the idea for the independent Common Cents Lab and snagged millions in annual support from the MetLife Foundation to make it happen.
Much of De La Rosa’s work involves what might seem like obvious observations about human behavior. After all, the save-it-before-you-see-it mind trick is a reason 401(k)s have been so successful and why employers are now considering offering automatic payroll deposits to rainy-day funds. But there are lots of twists to applying those insights in a useful fashion. Chime’s 10% automatic savings deduction is taken from every paycheck. By contrast, banks’ traditional savings programs transfer money on a set day each month—typically the 25th. Yet 70% of Americans get paid on a weekly or biweekly basis, and a single date-linked withdrawal can lead to bounced checks and overdrafts, says De La Rosa. Not an inducement for saving.
Chime’s Bank Fee Finder is based on Common Cents’ research showing people dramatically underestimate how much they pay in bank fees. Users go to Chime’s website, link their current bank account and get a precise accounting of how much they paid during the past year. The average—around $300—is powerful marketing for no-fee Chime.
One of De La Rosa’s key lessons for partners: Humans don’t like barriers and red tape, so make it easy for them to change their behavior. In one recent experiment, a sample of Credit Karma members were sent an email that said they could raise their credit scores by reducing their credit card utilization rate, suggesting they pay off a specific credit card and providing a click-through button to allow them to do so. While results aren’t yet public, De La Rosa says email recipients had a significant increase in credit scores compared with other members who must log in, call up their credit scores and then follow Credit Karma’s “credit coaching” advice.
In September, Common Cents got some competition. Acorns, a member of the Fintech 50, launched a “Money Lab” with Shlomo Benartzi, a professor of
Ariely says there’s a good reason startups are leading the way in behavioral-driven innovation. At traditional banks, he argues, “the incentives are to get people to overspend and overborrow. That doesn’t create an incentive to innovate and make better decisions.” Not that the fintechs, who must justify the hundreds of millions Silicon Valley has poured into them, are all so pure. De La Rosa points out a problem with free fintech services. “If you have a free product, your only business model becomes advertising,” she says. “So you get into the world of trying to sell people things that they don’t necessarily need.”
Maybe not such a politic thing to say, given that Credit Karma, a free service that rakes in hundreds of millions in referral fees from credit cards, is one of her many research partners. No matter. For De La Rosa, this is personal: “I think I just see my family in every single experiment that I run. I lived through that. I know exactly what it means to be living paycheck to paycheck.”
