Ukrainian Startups to Watch: Companies Driving Ukraine’s Tech Momentum
Ukraine’s startup scene has produced global products for years—and it keeps moving forward even under pressure. From learning platforms and creator tools to hardware, health tech, and sustainability, the companies below show what Ukrainian startups can look like when they build for international markets while staying closely tied to startups in Ukraine.
This is a mixed list: some teams are still in fast growth, while others have already scaled. Think of it as “startup roots + scale-up results.” Ukraine isn’t only a headline—it’s a place where teams keep building and scaling real products.
Why Ukrainian startups stand out right now
Many Ukrainian tech startups share the same strengths: a strong engineering culture, fast execution, and a global-first mindset. In recent years, teams also learned to operate as distributed teams and make decisions quickly—without turning every product story into a war headline.
Many teams build in English from day one, design for international customers, and ship updates fast because feedback loops are tight. You’ll also notice a rare mix of “software + real-world engineering”: AI tools, hardware, health solutions, and sustainability projects often grow side by side. And despite uncertainty, many founders keep investing in product quality, customer support, and long-term trust—exactly what helps teams scale beyond their home market.
10 Ukrainian startups and scale-ups worth knowing
Headway
Headway Inc was founded on 15 January 2019 by Ukrainian entrepreneur Anton Pavlovsky. The company builds consumer learning products (including Headway and Impulse) and is frequently mentioned as a Ukrainian-rooted team scaling global learning apps. Its products focus on short, habit-based learning formats designed for busy users. The company is often cited as an example of Ukraine-born consumer app execution at international scale.
Preply
Preply is a language-learning marketplace founded in 2012 by Kyrylo Bigay, Serhii Lukianov, and Dmytro Voloshyn. In January 2026, Preply announced a $150M Series D and stated the round valued the company at $1.2B—one reason it’s often discussed under Ukrainian unicorn startups. Beyond language lessons, Preply positions itself as a broader platform for skills and human-led learning supported by technology. Its global footprint makes it one of the clearest “Ukraine-to-the-world” product stories.
Grammarly
Grammarly was developed in Ukraine and launched in 2009 by Max Lytvyn, Alex Shevchenko, and Dmytro Lider. It’s now one of the most widely recognized Ukrainian-rooted writing tools, evolving into an AI-powered assistant for grammar, clarity, and tone. It became a daily productivity layer for students, professionals, and teams writing in English worldwide. Grammarly’s scale shows how Ukrainian-founded products can become category-defining.
Readdle
Readdle is a productivity software company founded in 2007 in Odesa, best known for apps like PDF Expert and Spark. As of 2024, Readdle’s software has surpassed 200 million downloads—an easy, source-backed signal of global traction. Readdle is a good example of long-term product craftsmanship: practical tools, frequent improvements, and a global user base. Its success also highlights Ukraine’s strength in building “boring but essential” productivity software.
Ajax Systems
Ajax Systems was founded in 2011 by Aleksandr Konotopskyi and builds wireless security systems that combine hardware and software. It’s one of the strongest “made in Ukraine” hardware examples, widely highlighted for international reach in the security/IoT space. What makes Ajax stand out is the full-stack approach—devices, apps, and ecosystem working together. It proves Ukraine can scale not only software, but also engineering-heavy hardware products.
Respeecher
Respeecher is an AI voice technology company founded in 2018 by Oleksandr (Alex) Serdiuk, Dmytro Bielievtsov, and Grant Reaber. It’s known for high-fidelity voice work in media and for completing the Comcast NBCUniversal LIFT Labs Accelerator powered by Techstars. The company sits at the intersection of AI and creative industries, where quality and trust matter as much as the tech itself. It’s also a strong case of Ukrainian AI being applied to real commercial workflows, not just demos.
Restream
Restream was founded in January 2015 in Vinnytsia by Alex Khuda and Andriy (Andrew) Surzhynskyi and helps creators stream to multiple platforms at once. It was reported to have raised a $50M round in 2020, supporting its status as a Ukrainian-founded product with global scale. Restream became infrastructure for creators, brands, and small media teams that want reach without extra complexity. It’s a clear example of a Ukraine-born tool built for a worldwide creator economy.
Esper Bionics
Esper Bionics is a Ukrainian-founded bionics and wearable-tech company founded by Dmytro (Dima) Gazda, Anna Belevantseva, and Ihor Ilchenko. In 2024, it was reported to have raised $5M to scale its bionic ecosystem and expand internationally. Esper’s story shows deep engineering moving into practical health and mobility solutions. It also reflects a trend: Ukrainian teams increasingly build at the edge of hardware, AI, and human-centered design.
Releaf Paper
Releaf Paper grew out of Valentyn Frechka’s work on producing paper from fallen leaves. English-language profiles also mention Alexander Sobolenko in the company’s leadership, and the project focuses on paper and packaging in a circular-economy model—sustainability as a manufacturable product, not just an idea. It’s a rare example of Ukrainian innovation that blends science, manufacturing, and climate-minded thinking. Releaf is also easy for international readers to “get” fast: a simple concept with real-world environmental value.
CheckEye
CheckEye is a Ukrainian HealthTech startup founded in 2022 that uses AI for large-scale screening of chronic diseases via retinal (fundus) image analysis. It won the EIT Health InnoStars Awards 2024, a strong external validation for a young team. The idea is preventive and scalable: help clinics screen faster and catch risk earlier using widely available imaging. CheckEye is a good example of Ukrainian AI applied to healthcare impact, not just productivity.
What these startups tell us about Ukraine’s innovation
First, Ukraine ships products people use at scale: consumer learning (Headway), productivity (Readdle), creator infrastructure (Restream), and globally known writing tools (Grammarly). That’s why these names often appear in “top Ukrainian startups” lists.
Second, Ukrainian AI startups are a core thread, not a side note: Respeecher applies AI to voice workflows, while CheckEye applies AI to preventive screening in healthcare.
Third, the ecosystem includes deep engineering and hardware (Ajax Systems, Esper Bionics) and sustainability-driven production (Releaf Paper). Together, that mix is a real snapshot of momentum.
Closing thoughts
Here’s the simplest takeaway: Ukraine keeps building—and shipping—products that compete globally. This list isn’t the whole ecosystem, but it shows why these names are increasingly becoming famous Ukrainian startups (or scale-ups): they’re already delivering real value, earning trust, and growing beyond the local market.
