About Tandem

Tandem is the language exchange app that brings together more than 30 million language learners. Members of the community form one-on-one Tandem partnerships to teach each other their native languages via text, audio, and video chat. Tandem has funding from some of Europe’s most prominent investors and is supported by Tandem Fundazioa, the organization that developed the tandem language learning method. Launched in 2015, the app is available for free on iOS, Android, and the Web.

Fun Facts

I have lived in 5 different countries to date.
One day in Warsaw, I accidentally sat at an Italian restaurant with Obama’s Secret Service without realizing it! Somehow, that lucky seat led me to be one of just 100 people from the public to attend his speech in person.
I’m passionate about mentoring future marketers. I love sharing everything I know, training people, and helping them grow into confident, skilled professionals.

Interview

What brings you joy in your role?

As VP of Marketing at Tandem, I love seeing the impact our product has on people’s lives. Language learning isn’t just about vocabulary and grammar: it’s about making real connections with people around the world. Hearing success stories from our members who have made lifelong friendships, advanced their careers, or even found love through Tandem is incredibly rewarding. It reminds me that our work goes beyond marketing, it’s about building bridges between cultures.

 

What is a common misconception about your role?

A common misconception about being a marketer is that it’s all about advertising and pushing products. At Tandem, our marketing isn’t just about acquiring users; it’s about fostering engagement, retention, and building a global community of passionate language learners. We don’t just run campaigns: we craft experiences that help people connect across cultures. Marketing is about storytelling, community building, and creating meaningful connections between a brand and its audience.

 

What challenges was your team experiencing before Iterable? How has Iterable helped address these challenges?

Before Iterable, we struggled to deliver personalized, timely messaging at scale without overwhelming users. Our previous setup lacked flexibility, making segmentation and engagement at key moments difficult. Iterable changed that with automation, dynamic segmentation, and embedded messaging, allowing us to deliver real-time, in-app messages when users are most engaged. Plus, its AI-powered tools optimize send times and content, boosting engagement and retention with less manual effort.

 

What are some Iterable features that have made your job easier? Or have been game-changers for yourself and your team?

Embedded messages have been a game-changer, allowing us to engage users in real time, directly within the app. Unlike other communication channels, they don’t disrupt the user experience: they appear when users are already engaged with the app, making messages feel natural and timely. Whether it’s guiding users, upselling them, or celebrating milestones, this seamless approach has significantly boosted engagement and monetization.

 

What do you think will be the next big thing in the marketing industry (AI, automation, new channels?)

Web3 & decentralization will change how brands interact with consumers. As blockchain technology evolves, users will own their data and identities, shifting the power from platforms back to individuals. This means brands will need to rethink engagement, focusing on community-driven marketing, tokenized loyalty programs and decentralized social experiences rather than relying on traditional ad-driven models.

 

How do you stay up–to–date with the latest trends and developments in marketing?

I stay up-to-date by reading industry newsletters (Marketing Brew, GrowthHackers), attending conferences, and engaging with marketing communities on LinkedIn and Slack. I also experiment with new tools and strategies: learning by doing is the best way to stay ahead.

 

What’s the best advice you’ve ever been given?

“Innovate or die” from Bob Iger’s book, The Ride of a Lifetime. The world moves fast and you need to be ahead of the game.

 

What is one goal you’d like to achieve in your lifetime?

One of my biggest lifetime goals is to train, mentor, and empower the next generation of marketers by not only sharing my knowledge but also creating an environment where they can truly grow. I believe that great marketing leaders don’t just teach, they nurture talent, provide the right tools, and cultivate an environment that encourages curiosity and innovation.

Tandem Boosts Conversion Rates with Abandoned Payment Recovery Journey

Objective

The goal was for Tandem to recover abandoned payments by leveraging personalized messaging to drive higher conversion rates and reduce payment drop-offs.

Summary

Tandem implemented an Abandoned Payment Recovery Journey in Iterable, which triggers embedded messaging in the app within the checkout process when a user initiates a payment but doesn’t complete it. The message offers a tailored upsell or incentive to encourage completion at the most opportune moment. If the payment remains incomplete, Tandem sends a follow-up push notification and in-app message a few hours later, reinforcing urgency and emphasizing the value of completing the transaction.

Results

This multi-touch, strategic approach resulted in a significant uplift of 15% in payment completions for Tandem, driving higher conversion rates and delivering a measurable revenue impact.
