Posti

Posti’s history spans over centuries. What started with delivering quill-written letters in the 1600s has grown into a modern-day tech company that continues evolving with its customers. Today, Posti is much more than just logistics: it’s a modern technology company, offering cutting-edge digital products and services. 

Specifically, Posti’s TechHub combines Posti’s heritage of reliability with trailblazing capabilities, developing digital solutions that power e-commerce, logistics, and communication services. Behind the scenes, billions of logistics data points are processed each year, over a million people use OmaPosti every month, and more than 200,000 kilometers of delivery routes are optimized daily. All of this requires well-oiled cross-functional teams, and Posti has trusted several partners in making their digital dreams a reality.

At Reaktor, we’ve been partnering with Posti on their digital journey since 2002. A partnership spanning more than 20 years means more than just project milestones. It means building digital muscles together, creating habits of innovation, and continuously improving the everyday experiences of millions.

Reaktor’s work with Posti has touched nearly every layer of their digital operations – from how a warehouse worker checks their schedule to how a consumer tracks a package in transit. We've helped Posti deliver smoother services to over 3 million app users, streamlined the backend for better delivery logistics, and empowered Posti teams with tools they actually enjoy using.

This partnership exemplifies the long game: trust built through iterative improvements, curiosity that fuels reinvention, and shared ambition that makes the work feel less like service delivery and more like shaping the future together. Posti’s software development culture is welcoming and one-of-a-kind: Reaktorians and Posti’s internal teams work seamlessly side by side as a unified team.

Digital pioneers in postal services

In the early 2000s, when digital services in logistics were still rare, Posti and Reaktor teamed up to launch forward-looking solutions: from online address changes to digital redirection services. Together, we developed some of Posti’s first online tools, making core services more accessible and proving that even legacy systems could evolve. These weren’t just efficiency plays; they set the tone for what user-focused digital government and logistics could look like.

“We weren’t just putting services online. We were showing that digital could unlock real value.”

Making parcel tracking user-friendly

Parcel tracking was the next frontier of our collaboration at the beginning of the 2010s. We overhauled Posti’s website and streamlined service discovery. What had been clunky and slow became human-centric and intuitive. Reaktor’s design and engineering teams helped Posti redefine what customers could expect from delivery services.

Design thinking enters the back office

Midway through the previous decade, we brought design thinking into Posti’s internal systems, applying user-centered principles to logistics, route planning, and operations. Our teams introduced agile practices that helped Posti move faster and work smarter, aligning business priorities with real-world needs.

OmaPosti reimagined

In recent years, we led a full redesign of OmaPosti, Posti’s flagship app. This wasn’t only a fresh coat of paint, but a user-first reinvention. We brought together parcel tracking and digital mail in one elegant, streamlined mobile experience that millions now rely on. Today, OmaPosti has over a million monthly users.

Redefining website strategy and content

With Posti’s brand evolving, the digital expression needed to keep pace. Our content strategists partnered with Posti on a full overhaul, shaping a new website ecosystem built around clarity, utility, and brand voice. We ensured that the language, tone, and structure of digital services are just as well-crafted as the code behind them.

Two decades and a myriad of different projects in, and we’re still not done. Reaktor continues to support Posti with full-stack teams embedded across service areas – from consumer experiences to operational systems to forward-looking R&D. Posti is also rapidly growing internationally, and we are excited to keep bringing the technological expertise beyond borders. 

Together, we’re building not just what’s next, but what endures.
