Readmio Secures EUR 1M to Scale Human-Centered Storytelling Globally

• Czech edtech Readmio raised EUR 1M, accelerating global expansion and product development efforts
• The startup shows significant growth in subscriptions, users, and engagement metrics year over year
• The platform differentiates itself through human storytelling, deep localization, and rejection of AI voice replication
• Readmio’s future focus is international scaling, improved distribution, and standing high quality of user experience

This February, the well-known Prague-based audio-enhanced children’s literature digital publisher Readmio secured EUR 1M of Seed Investment from its standing supporter, Polish impact investment firm Simpact Ventures, only a year after the startup’s previous funding.

A Mission to Transform Reading

Readmio was founded in 2020 by Jozef Šimko (CEO), Ilya Novodvorskiy (Head of Growth), and Radoslav Rajčan (Head of Development). The founding team consists of parents aiming to improve children’s development through storytelling, with a mission to make daily reading a global habit.

From the start, Readmio differentiated itself by combining traditional read-aloud storytelling with technology: its mobile app uses voice recognition to trigger sound effects and music in real time, creating an interactive yet screen-light experience. This approach positioned it as an alternative to passive screen time, emphasizing imagination, emotional development, and parent-child bonding.

After launching, the app expanded steadily across platforms (iOS, Android, web) and languages, while building a growing library of hundreds of original and adapted stories, often developed with educators and child-development experts. The startup gained traction among families globally and received multiple awards in edtech and startup competitions.

Today, the app’s library counts 3,200+ stories in English, Czech, Slovak, Polish, German, Italian, Spanish, Portuguese, and Hindi.

Breakthrough Growth and Strong User Engagement

Mr Šimko calls 2025 a breakthrough year for Readmio. According to the startup’s numbers, it grew almost 2.5x year over year, surpassing 60,000 active subscriptions, while monthly active users increased 3x and families have now listened to over 10 million stories through Readmio.

Meanwhile, the app maintains a 4.8-star rating across iOS and Android, with reviews more than doubling. This is particularly noteworthy considering the scale — more than 2 million downloads.

Readmio also got selected into the Deloitte Technology Fast 50.

‘This recognition is particularly meaningful to us because it is based on verified actual numbers and growth over time, rather than subjective evaluation. It reflects real, measurable progress,’ Mr Šimko notes.

‘On the product side, we rolled out audiobooks across all languages, introduced new profile features and gamification elements, and shipped numerous smaller improvements that enhanced the overall user experience,’ the CEO adds.

Moreover, Readmio secured several meaningful partnerships. For example, collaboration with T-Mobile drove strong trial and subscription growth through bundled distribution, representing large-scale strategic partnership and validates the strength of our offering.

In-Depth Localization and Cultural Adaptation

‘At the same time, the biggest challenges remain entering new markets and breaking through marketing ceilings. Distribution and scalable acquisition are significantly harder than building a product people love. The encouraging part is that as we grow, partnerships are becoming easier — the brand is stronger, awareness is higher, and we now have an established base of partners who trust us,’ Mr Šimko admits.

Understandably, localization is among the most complex parts of Readmio’s work. For every country, local editors, writers, and translators are invited. Stories get culturally adapted as opposed to being simply translated, as humor, moral framing, pacing, character archetypes, and even bedtime expectations differ significantly across markets.

In some countries, Readmio even got to team up with well-known local authors to secure exclusive stories. In others, the team co-creates custom stories with regional partners to reflect local traditions or seasonal themes to ensure authenticity. This is particularly important in regions with their own specific oral storytelling traditions.

‘In every market we enter, partnerships are a key part of our strategy. We collaborate closely with local authors, translators, editors, and educators to ensure that our content feels authentic and culturally relevant. In some countries, we’ve worked with well-known writers to create exclusive content for the app. In others, we have developed custom stories together with major regional partners to better reflect local traditions, values, and cultural nuances,’ Mr Šimko tells ITKeyMedia.

This approach is especially important in markets with strong oral storytelling traditions, where authenticity and cultural sensitivity matter deeply.

Community Creation vs Quality Control

Creator contributions and community publishing seem quite logical and have been extensively discussed inside the Readmio team. However, the challenge here is safeguarding children and maintaining content quality. An open publishing platform would require enormous moderation and quality control, and the bar is particularly high for the children audience. That’s why what Readmio considers instead in this regard is a private creation feature — where parents could create their own sound-enhanced story and share it privately with selected family members, not be an open marketplace or public feed. Still, this is not part of the 2026 roadmap.

Pricing, Value, and Market Complexity

Another significant challenge is to balance affordability, perceived value, and sustainable unit economics. The product-market fit is strong — reflected in the mentioned 4.8-star ratings across app stores.

‘But marketing and distribution economics vary dramatically by country. Our goal is to keep pricing realistic for the average family while maintaining sustainable unit economics. In some markets, partnerships—like telecom bundles—significantly improve CAC efficiency. In others, organic growth is stronger. There is no universal pricing formula. It’s a continuous optimization process,’ Mr Šimko shares.

A Human-First Stance on AI

At that, the Readmio team remains strongly sceptical about AI-powered replication of parents’ voices, even in view of the success of startups like ElevenLabs. The founders emphasize that their startup is building a ‘love brand,’ which means that users must feel warmth and human touch in every interaction.

Naturally, AI gets used operationally — to improve internal workflows, productivity, and tooling — but not in any customer-facing aspect. Readmio assures that all stories are written by humans, as well as all customer support is handled by real people.

‘Many companies automate customer interaction with AI chatbots, and the experience often feels cold and transactional. We want the opposite. Readmio is about the connection between parent and child. That emotional layer cannot be synthetic. We are not pursuing AI voice replication of parents because it undermines the very ritual we are trying to protect — shared reading,’ Mr Šimko states.

Impact Beyond Metrics

Seeing how Simpact Ventures, one of Readmio’s loyal backers, is an impact investor, Readmio has to measure success far beyond downloads or listening time. In addition to educational KPIs, the company tracks less apparent indicators such as carbon footprint. Naturally, the team closely monitors reading frequency, story completion rates, and engagement with additional quizzes and comprehension features to understand how families are truly interacting with the content.

To increase insight, Readmio is increasingly collaborating with schools and working directly with teachers and child psychologists. This gives Mr Šimko and his team a much deeper educational perspective.

‘It’s more than just about how many stories are read or how many quizzes are completed — we conduct qualitative interviews, user testing, and ongoing conversations with educators and parents to better understand the real impact on children’s learning and reading habits. Engagement metrics matter, but our ultimate benchmark is sustained behavioral change — whether we are genuinely strengthening long-term family reading routines,’ the CEO explains.

‘We believe in the Readmio team’s growth vision. We understand each other well. The technology is successfully entering new markets and users rate it highly. Spending quality time with children is crucial to their development. Beyond the enormous business potential, there is real social impact consistent with the fund’s investment policy. Our investment will enable faster product development and, above all, faster scaling into new markets such as India, China, and other Asian markets,’ Simpact Ventures’ CEO and general partner Krzysztof Grochowski comments.

What Comes Next

More specifically, Readmio will use the newly raised EUR 1M to accelerate growth and continue enhancing the product while preserving the platform’s definitive quality. According to the co-founders, a major focus will be placed on expanding into new markets, including launching at least three new languages this year, as well as releasing several new features that further improve the user experience. At the same time, Readmio intends to continue strengthening distribution partnerships and continue building scalable international channels. The ambition is to achieve 3x revenue growth year over year.

‘One year from now, success would mean reaching that sustained growth rate while gaining strong traction in newly launched markets, improving marketing efficiency, and continuing to grow active subscriptions. Just as importantly, we aim to maintain our 4.8+ stars in app store ratings at scale — something that reflects real customer satisfaction, not just growth,’ Mr Šimko wraps up.

Ultimately, revenue is the clearest leading indicator of progress, but it is not the only one. As Readmio scales, it is equally important to preserve what makes this platform special: an inherently human, emotionally resonant experience that strengthens family reading routines and remains a brand families can genuinely trust and love.
