Czech Fourtly Raised EUR 1.65M to Take Its Personalised Video Platform to the US

• Brno-based Fourtly nabbed EUR 1.65M to expand its personalised video platform into America
• Its on-device rendering architecture aims to make personalised video scalable and cost-efficient
• European customers and campaign results provide evidence supporting Fourtly’s US expansion strategy
• Following the investment, Fourtly plans product, AI, sales, and international expansion

Czech startup Fourtly (formerly known as Webout) raised EUR 1.65 million to take its real-time personalised video platform from its European customer base over the Atlantic Ocean and into the US. The Seed round was led by Seed Starter SK, with Energy Venture Pals and JIC Ventures also participating, as the Brno-born company shifts from proving its technology in Europe to building a commercial presence in the American market. Co-founder Michal Orsava has relocated to San Francisco to lead the expansion, with sports, enterprise marketing, and other data-rich industries among the initial targets.

Five Years Building Personalised Video

Prior, the company has spent roughly five years developing technology that allows video to adapt to individual viewers rather than delivering the same finished file to everyone. Fourtly’s current SaaS platform lets brands, sports teams, and enterprises create personalised and interactive video experiences at scale, with the content generated on the user’s device rather than being fully rendered centrally. Its customer roster includes Česká spořitelna, Komerční banka, Allianz, Notino, AC Sparta Praha, and Club Brugge.

The idea began with Mr Orsava, whose background spans advertising, filmmaking, and storytelling rather than software engineering. He had seen how brands struggled to make video communication genuinely relevant to individual viewers and began asking whether the viewer could become part of the story, while co-founder and CEO Karel Juřička brought the technical experience needed to turn that concept into a product. Their combination of creative and engineering backgrounds became the foundation for what was then Webout.

‘The initial idea for Webout came from me: What if the viewer could actually become part of the story? Karel brought the technical depth to turn a concept that sounded almost impossible into something that could actually work. That combination ultimately became the foundation of Webout: creativity and technology coming together to rethink what video could be,” Mr Orsava recalls. His role has since remained closely tied to understanding how brands communicate and what makes people stop, watch and share, while Mr Juřička has focused on the underlying technology.

The technology became viable only after several pieces of the digital ecosystem matured at roughly the same time. For years, personalised video largely meant generating separate files on central servers, an approach that becomes expensive and cumbersome when a campaign reaches hundreds of thousands or millions of viewers. Fourtly instead sends the components and instructions required to assemble the experience, allowing much of the rendering to happen on the viewer’s device.

‘On-device rendering is one of the fundamental architectural decisions behind Webout. The biggest advantage is scalability, because delivering one million personalized videos through conventional server-side rendering could require enormous computing resources, storage and cost. With Webout, much of that work happens directly on the user’s device,’ Mr Juřička explains. The architecture also creates engineering challenges because the company has to account for different devices, browsers, operating systems and network conditions.

From Experiments to Enterprise Software

The approach has been evolving alongside the company itself, which initially worked more like a creative technology studio than a conventional SaaS business. Early projects tested how far video could be pushed, including whether it could react to information about the viewer, incorporate interaction or change while someone was watching. The next challenge was turning those experiments into something enterprises could use repeatedly without Fourtly having to build every campaign itself.

‘The first phase was experimentation, and then came the second phase: proving that this technology could solve real business problems. We moved from experiments into marketing and communication use cases and gradually started working with larger companies, while projects with brands and organisations such as Česká spořitelna, Komerční banka, Allianz, Notino, AC Sparta Praha, and Club Brugge showed us that personalised video could deliver measurable results and work at enterprise scale,’ Mr Juřička tells ITKeyMedia. The turning point came when the company began transforming the underlying technology into a platform that customers could operate themselves rather than buying individual bespoke campaigns.

That transformation accelerated after Webout’s first external investment, a EUR 340K Pre-Seed round by DEPO Ventures and Venture Buddies in early 2025. The funding helped the company develop its first SaaS platform, while Česká spořitelna became one of its early major customers to use the technology internally and launch campaigns independently. By the end of 2025, the twelve-person team had generated EUR 600K+ in revenue, according to the company.

Silicon Valley as the Next Strategic Target

The European traction also gave Fourtly a basis for testing whether the concept could travel beyond its home market. A three-week accelerator programme in Silicon Valley in 2025 exposed the founders to potential US customers and partners and changed the American market from a distant possibility into a concrete strategic target. That validation now underpins the company’s decision to have Mr Orsava build the US operation from San Francisco rather than manage the expansion remotely from Europe.

‘What specifically convinced us that the US market is ready is the combination of a sophisticated digital advertising and sports ecosystem, increasingly valuable first-party data, and a major shift in how companies think about personalised content. Generative AI has changed the conversation, because companies increasingly assume content will become dynamic and personalised, and the question is now how to produce, orchestrate, and deliver it reliably. That’s exactly where Fourtly sits,’ Mr Orsava argues. He sees professional sports as a particularly promising entry point because clubs may have millions of fans but still communicate with them using largely identical content.

Fourtly’s European campaigns give that pitch some evidence beyond the founders’ expectations. A campaign for AC Sparta Praha generated 1.7 million organic views without paid media, while the company reports completion rates of up to 95% and click-through rates as much as ten times higher than conventional video campaigns. The current platform also supports integrations with tools including Salesforce, HubSpot, Microsoft Dynamics 365, Shopify, and more marketing systems, while Fourtly claims its videos can be generated directly on users’ devices without requiring customer data to be stored for the personalisation process.

Balancing Cloud, Device, and AI, While Making Personalisation Feel relevant, Not Intrusive

For Mr Juřička, the technical proposition is not simply about moving computation away from the cloud. The company is increasingly using a hybrid architecture where different tasks get handled on the client or in the cloud, while AI adds another layer for deciding which content should get created and delivered. This balance is intended to optimize scalability alongside speed, quality, privacy, and cost rather than treating on-device rendering as an end in itself.

‘Personalisation itself isn’t the value; relevance is the value. Just because you have twenty data points about somebody doesn’t mean twenty data points should appear in the video, because making every piece of available information visible could quickly become deeply uncomfortable. The viewer should ideally think, ‘This is really relevant to me,’ rather than, ‘How the hell do they know that?’ Mr Juřička argues that the most effective personalisation can be almost invisible, with the system quietly changing a scene, sequence, product or call to action instead of displaying an obvious collection of personal details.

Scaling the Product after the Funding

The new capital therefore gets divided between product development, go-to-market and international expansion rather than used solely to establish a US sales office. Fourtly wants to make sophisticated personalised video campaigns increasingly self-service, use AI to accelerate the creation of voices, images, languages and scenes, and build a repeatable sales process that is less dependent on founder-led selling. A Series A is currently planned around the end of 2027.

‘Success means proving Fourtly can become a global category company. We’ll focus on recurring revenue growth, increasing SaaS share, repeat usage, account expansion, and building a meaningful US customer base. Equally important is product independence: how quickly can customers go from data and creative assets to a live campaign without our team building it manually?’ Mr Juřička states. The test is therefore about whether Fourtly’s US customers can independently use the platform at a scale that turns personalised video into a recurring software product.

JIC Ventures, which joined the Seed round as its second investment since launching its new fund in April 2026, sees the combination of technology and existing commercial traction as the reason to back the expansion.

‘Fourtly is exactly what we look for in an investment. An experienced team that has built a scalable platform on advanced technology, with hyper-personalisation positioned to grow as a category,’ JIC Ventures managing partner Radim Kocourek comments, adding that the company is already ahead of where he believes the market is heading and framing the investment around the platform’s future potential rather than its existing campaign business.

His colleague Miloš Sochor also points to the founders’ ability to combine technical expertise with an explicit international ambition. The investment comes as Fourtly moves into a market where its founders believe the gap between the amount of customer and fan data organisations possess and the generic content they distribute remains substantial. That gap, particularly in sports and entertainment, is where the company expects its technology to find its strongest early US use cases.

‘The team has deep domain expertise and extraordinary drive. Combined with a clear goal of breaking into the US market — including the sports segment — it was a strong signal for us to invest,’ Mr Sochor remarks. For Fourtly, its US push is the next test of whether a technology developed in the Czech Republic can become part of a much larger global communications market.

Beyond Personalised Video

‘Our long-term ambition is bigger than personalised marketing videos. Today, video is something created once and watched by millions, but in the future content could be generated and assembled specifically for each person in real time, based on context, preferences, behaviour, and interaction. We want personalised content to become as normal as personalised websites are today,’ Mr Orsava concludes. Fourtly’s US expansion is therefore more than a new sales territory for the company: it is the next step in testing whether its Czech-built approach to dynamic content can scale into a global SaaS business.

Fourtly’s bet is on personalized, adaptive content as a fundamental part of how brands communicate, moving beyond one-size-fits-all video towards experiences tailored to each individual viewer. The EUR 1.65M funding round gives the company the resources to turn five years of technological development and European traction into a more scalable SaaS business, while investing in the product, AI capabilities, and a repeatable go-to-market model. Its expansion into the US now represents the biggest test yet of that vision—and of whether technology built in the Czech Republic can compete in one of the world’s most sophisticated and demanding digital markets.
