Behavioral design in action

Guiding the customer's decision changed the outcome

Every intervention starts with a simple question: what is preventing this person from buying, signing up, or doing what we need them to do? The answer is validated through experimentation, applying behavioral principles and psychological biases. All results were achieved by members of the BELAB team.

Credit cards

Cash withdrawal in installments

A product that allowed customers to withdraw cash in installments from their credit card was underperforming: few clicks, little interest.

What we found

The problem was not price. People felt uncomfortable using a credit card to withdraw cash, even when it was cheaper than taking a loan. It was emotional, not rational. We changed the message to speak about specific moments, like a trip or an unexpected expense, instead of rates.

Result

Clicks doubled, and the digital channel reached its best historical performance for two consecutive months.

Insurance

Speaking differently to each buyer type

A high-priced car insurance product was promoted with the same message for every customer.

What we found

Not everyone buys car insurance for the same reason: some seek status, others peace of mind, others distrust the price. We spoke to each group in its own language instead of using one generic message.

Result

Interest multiplied several times in each group; in the most receptive one, it multiplied by five.

Savings accounts

Digital acquisition

Digital advertising to acquire new payroll-account customers was not generating enough interest.

What we found

Instead of listing benefits, we showed customers that other people like them had already opened the account. Seeing that "someone like me already did it" builds more trust than a list of advantages.

Result

Interest almost doubled, and reach increased by 75%.

Personal loans

Debt consolidation

An email campaign encouraging customers to consolidate debts into one loan had low open rates.

What we found

We tested two ways of writing the message: one explaining rate benefits, and another more direct and close, saying simply "we help you with your debts." The closer version won by a wide margin.

Result

+25% more opens from the first send.

SME capital

Working capital for small businesses

A product that gave micro-entrepreneurs access to cash had weak traction despite good conditions.

What we found

Business owners were not excited by the idea of "investing to grow." They cared about solving something urgent, such as paying a supplier. We changed the message to speak about that.

Result

The product doubled its share within digital sales for the segment in less than a year.

Mortgage

Contacting the customer before they search for you

Mortgage advisors only sold when the customer contacted them first, without a proactive outreach plan.

What we found

We designed email and WhatsApp messages so advisors could reach customers at the right moment, with a tone built to generate trust from the first contact.

Result

Twice as many people advanced in the buying process compared to those who did not receive that first contact.

Loyalty program

Credit card points and benefits

A campaign to get customers to use their card points was not working. The team assumed customers already knew how points worked, and that was the problem.

What we found

Most customers had no idea what they could do with their points or how to redeem them. Instead of listing every benefit at once, we created an email explaining only three basic things, simply and in order. Less information, but clearer.

Result

Email interest grew almost five times, and customers who actually redeemed points increased significantly.

Collections

Training the call center to handle difficult conversations

Debt recovery depended on a standard script, without special preparation to manage difficult conversations.

What we found

We trained advisors in a four-step conversation: gain attention, help the customer reframe the problem, support the decision, and motivate action without overpressuring or sounding indifferent.

Result

The trained group recovered more money than the untrained group, and the difference grew as they practiced more.

.. And more results in sectors such as retail, education, and others.
