Seamless OS wins Cloud Native Network Leader and CMO of the year at The Fast Mode Awards 2025

Telness Tech has secured a double victory at The Fast Mode Awards 2025, being named Cloud Native Network Leader globally – while Sebastian Stecki, CMO of Telness Tech, has been recognized as CMO of the Year.

The Fast Mode Awards spotlight the platforms and leaders transforming global connectivity, with judges assessing real-world outcomes in performance, innovation, impact, and growth across both technology and leadership categories.

Cloud Native Network Leader – Performance

In the Cloud Native Network Leader category, Telness Tech’s Seamless OS was recognized as the best in the world in Performance, joining a select group of platforms that are redefining how telecom networks are designed, scaled, and operated in the cloud.

The category honors cloud-native networking innovations – from platforms that manage deployment and lifecycle in the cloud to solutions architected around microservices, container orchestration, service mesh, CI/CD automation, and edge-cloud integration. Judges evaluate how each solution advances key telco goals such as flexibility, agility, scalability, and efficient resource utilization, as well as measurable gains in deployment speed, total cost of ownership, and service performance.

“The calibre of entries this year was extraordinarily high,” commented Tara Neal, Executive Editor at The Fast Mode. “Against tough competition, Telness Tech stood out with its modern, next-generation Seamless OS platform that delivers not only technical excellence but real-world value to operators seeking agility, scalability and cost‑effective transformation.”

Seamless OS, Telness Tech’s flagship platform, was designed precisely for this new reality:

A fully cloud-native, end-to-end telecom operating system that lets operators launch and run fully digital services with deep automation across the entire customer journey.
AI-ready, agentic workflows that automate complex operations, from onboarding and billing to notifications and lifecycle management.
A SaaS model that allows operators of any size – including new MVNOs and non-telco brands – to go live quickly while significantly reducing operational overhead.

Sebastian Stecki Named CMO of the Year

The second win comes in The Fast Mode’s Leadership Excellence category, where Sebastian Stecki, CMO of Telness Tech, has been named CMO of the Year - Globally.

The CMO of the Year award recognizes marketing leaders who drive impactful brand and growth initiatives – from customer acquisition and brand repositioning to strategic partnerships – with evaluation focused on outcomes such as , campaign ROI, product marketing quality, media footprint, and brand strength, as well as their use of AI and guerrilla marketing to create new storytelling formats.

The Fast Mode states: "The award honors Sebastian for his remarkable contribution to the industry, specifically his role at Telness Tech, where he oversaw a full brand repositioning — recasting the firm from a Scandinavian MVNO‑enabler into a global challenger in cloud‑native telecom software. Under his guidance, Telness Tech launched Seamless OS, a next‑generation platform that enables operators and MVNOs worldwide to launch fully digital, automated mobile services."

Of several notable achievements, Sebastian also drove a complete ICP-focused digital marketing overhaul, oversaw the launch of an entirely new product marketing engine, and executed a comprehensive international PR and communications engine from scratch —generating widespread international coverage for the company.

"Selecting this year’s CMO of the Year in the solution provider category was not an easy choice, as we sought to recognize leaders who have driven impactful initiatives and forward-thinking strategies across their marketing efforts in this challenging domain,” said Tara Neal, Executive Editor at The Fast Mode. “We are honoured to recognize Sebastian for his outstanding contribution to the company’s strategic repositioning and international growth, and his role elevating Telness Tech’s profile among operators globally.

“ This recognition is really about the story we’re writing as a company,” said Sebastian Stecki, CMO at Telness Tech. “We’ve proven that a focused team, a sharp narrative, and a product that truly delivers can punch far above its weight on the global stage. The Fast Mode Awards put us side by side with the biggest names in telecom, and that’s a direct result of the work our entire team – from product and R&D to sales, delivery, and marketing – does every day.”

Momentum for Seamless OS – and for AI-First Telcos

These two Fast Mode Awards add to a growing list of global recognitions for Seamless OS, including wins at MVNO Nation Awards and MVNOs World Awards, and finalist positions in four separate categories at The Fast Mode Awards 2025 – AI Gamechanger, Cloud Native Network Leader, OSS & Automation Leader, and Digital BSS Trailblazer.

Together, the awards underscore Telness Tech’s role in enabling AI-ready, cloud-native operators that can launch faster, operate leaner, and differentiate through automation rather than complexity.

Being named Cloud Native Network Leader globally is a powerful validation of what Seamless OS was built to do,” said Martina Klingvall, Founder & CEO, Telness Tech. “We set out to make telecom radically simpler – to give operators a fully automated, cloud-native foundation that scales without adding complexity. These award recognizes not only our capabilities to change the industry - but also the leaders and teams and talent make sure our product reaches our audiences and customers, changing the entire industry."
