A decade of messaging innovation

Founded nearly 10 years ago, Quriiri specializes in a messaging platform supporting SMS, email, RCS, and other channels. Its mission is to help businesses reach their customers effectively, regardless of size, from solo entrepreneurs to public organizations.

Thomas Wahlberg, CTO of Quriiri, explains, “Our customers have very diverse needs. Some send critical one-time passwords, while others send marketing messages or general updates. Our job is to ensure those messages reach their audience reliably and securely.”

Trust and security at the core

A key differentiator for Quriiri is the emphasis on trust and verification. Historically, SMS traffic has faced challenges with scams and fake sender IDs. Quriiri has tackled this head-on, implementing robust sender verification processes, particularly as richer messaging formats like RCS gain traction.

“Users need to know the sender is who they think it is. With RCS, this verification becomes more robust, and it builds confidence in every interaction,”

Security isn’t just about compliance but a daily practice. Quriiri enforces multi-factor authentication, strict access control, SSH key usage, and regular cleanup of data. It also has disaster recovery plans in place so that even in worst-case scenarios, the platform can be restored quickly.

Scaling infrastructure for modern messaging

Running a messaging platform at scale is technically demanding. Quriiri’s platform includes a database, message queues, and tens of microservices. To meet performance needs:

• MaxIOPS Block Storage ensures fast database transactions and microservice performance.
• Object Storage provides cost-efficient media storage for rich content like images and videos.

All of this runs on UpCloud infrastructure, providing reliable, high-performance servers that can scale according to demand.

“Using UpCloud’s infrastructure has been crucial. It allowed us to provide configurable servers through a user-friendly interface, and it gave us the reliability we needed from day one.”

Preparing for the future: RCS, automation, and high availability

The messaging landscape continues to evolve. Quriiri is preparing for:

• RCS adoption, enabling richer messaging experiences.
• High-availability setups to ensure uptime even under heavy load.
• Infrastructure as Code, with Ansible now and Terraform next, to streamline deployment and recovery.

Automation plays a central role in maintaining speed and reliability. From monitoring system metrics to proactive alerts, Quriiri ensures potential issues are detected and resolved before they impact customers.

Lessons learned from a decade of growth

Reflecting on infrastructure, Wahlberg shares a core lesson in that problems are inevitable, but preparation makes all the difference. Having the right team, processes, and tools allows Quriiri to respond quickly and maintain trust with its customers.

“Unexpected issues will always occur. What matters is having a plan, automation, and a team that knows how to tackle challenges effectively”

Why GDPR and data sovereignty matter

Operating in Europe, Quriiri’s customers often require that all systems and data remain within the EU, particularly in Finland. This ensures low latency, compliance with GDPR, and stronger privacy protections. Choosing infrastructure like UpCloud’s that runs in European data centers helps meet these requirements while delivering a seamless messaging experience.

Final thoughts

Quriiri’s journey illustrates how modern messaging is about more than just sending texts. It’s about building trust, reliability, and compliance into the very infrastructure of communication. By combining innovative messaging technologies with UpCloud’s high-performance infrastructure, Quriiri empowers businesses to connect with their customers securely and efficiently.

Whether you’re a developer, architect, or business leader, Quriiri’s story provides valuable insights into the technical, operational, and strategic considerations behind running a robust messaging platform at scale.
