Dioma targets a gap in language-learning market

Geoffery Bloom spent years studying Spanish and Hebrew, but like many language learners, he found himself hitting a wall. While beginner-focused platforms made it easy to learn vocabulary and basic phrases, Bloom said fewer tools existed for learners trying to push toward fluency.

That experience led Bloom to launch Dioma, an AI-powered language learning platform designed for intermediate and advanced learners.

Founded in 2025, Dioma combines educator-built curriculum with AI-driven personalization to create customized lesson plans for users studying Spanish, French and Hebrew. The platform launched earlier this year and is currently in beta. Users subscribe through monthly, quarterly or annual plans that provide access to personalized written and spoken exercises.

“The goal is to sharpen what you do know well and help you learn the more obscure smaller pieces that you might not have learned,” Bloom said.

Bloom previously worked in brand management at SC Johnson for more than a decade. After spending the past year building the platform and testing it with early users, he is now focused on growing Dioma full time.

Rather than moving learners through a fixed curriculum, Dioma adapts based on user performance. The system continually adjusts lesson plans to emphasize areas where learners need additional practice.

“If you know something well, you’re not going to see it very often because you’re an intermediate learner and already have that foundation,” Bloom said. “It’s going to focus you on the things that you don’t know as well.”

To build the curriculum, Bloom worked with educators and curriculum designers who created instructional frameworks for each language topic. That material is paired with AI tools that analyze spoken and written responses to provide feedback.

Bloom said he intentionally avoided the heavily gamified approach used by some mainstream language-learning platforms.

“All language learning platforms have to figure out the right balance of engagement versus actually helping you make progress,” Bloom said.

Instead, Dioma targets learners who are already committed to improving their language skills and want more focused practice than beginner-oriented apps typically provide.

The company launched with Spanish, French and Hebrew and plans to add additional languages over time, including those with fewer advanced learning resources available.

While the company remains in its early stages, Bloom believes the combination of AI-powered personalization and human-designed curriculum fills a gap in the language-learning market.

“The goal is to help intermediate and advanced learners make progress,” Bloom said.
