Tremend

Tremend is a software engineering company based in Bucharest, Romania, with over 900 engineers. Founded more than 16 years ago, the firm operates as a delivery center for Publicis Sapient following Publicis Groupe's acquisition in 2022. The company delivers software for Global 500 customers across banking, healthcare, automotive, telecom, and eCommerce sectors, reaching 60 million end-users through its client solutions.

Tremend works across the full software development lifecycle: custom web and mobile applications (iOS, Android, React Native, Flutter), embedded systems and firmware, IoT platforms, data science and big data analytics, enterprise architecture, DevOps, and RPA implementation. The firm has completed 200+ custom software projects and delivered over 100 mobile apps. Its engineering team focuses on complex, mission-critical systems rather than commodity work.

Services and capabilities

On the software engineering side, Tremend offers custom application development in Java, PHP, .NET, C/C++, and Ruby, alongside modern frameworks like React, Angular, and Next.js. Mobile work spans native iOS/Android development and cross-platform solutions (React Native, Flutter). The company builds progressive web apps, APIs, and handles application modernization and legacy system porting.

For enterprise and infrastructure, services include solution architecture, enterprise business solutions (ERP, back-office systems), DevOps and high-complexity infrastructure engineering, IoT software development, and cloud solutions. On the innovation side: data science with structured and time-series data, machine learning integration (CoreML, ML Kit), RPA automation, and agile transformation consulting.

Quality assurance spans functional, integration, load, and usability testing. Tremend uses Selenium, Appium, Protractor, Specflow, and Tosca for automation. The firm also offers consultancy on QA process definition, performance testing, and security testing (OWASP, PCI compliance). Mobile apps include deep linking (Branch, Firebase), augmented reality (ARKit, ARCore), and wearables/IoT integration (BLE, NFC, SmartWatch, interactive TV).

UX/UI design is in-house for both web and mobile; award-winning case studies mention Regina Maria and First Bank. Tremend also builds custom content management systems (300+ projects delivered) and provides eLearning platforms.

Andrej Poljanc at Mobipro stated "Every single minute work with Tremend is worth the investment."

How they work

Tremend follows a seven-step agile process: requirement gathering, UX/UI design, prototyping, application development, quality assurance, deployment, and maintenance/support. The firm offers flexible engagement models—dedicated teams, non-dedicated, or hybrid arrangements. Pricing models are negotiable to ensure client satisfaction.

Mobile development includes MVP innovation workshops, lean product testing, user-centered discovery and research, rapid prototyping, and usability testing. The company provides pre-built modules and boilerplates to accelerate deployment. Quality is enforced through automation pipelines and real-time crash reporting. Security includes code obfuscation, encryption, and compliance with industry standards. Post-launch, Tremend supports A/B testing, analytics integration, and in-app messaging for growth.

All software engineers undergo ongoing coaching and continuous training throughout their engagement. Project managers ensure budget alignment, on-time delivery, and operational transparency.
