Yalantis

Yalantis is a full-cycle software, hardware, and IoT development firm based in Dnipro, Ukraine, with offices in Warsaw, Tallinn, Larnaca, and Dnipro. Founded over 17 years ago, the company now operates with 400+ engineers across multiple locations. They specialize in end-to-end product development spanning embedded systems, PCB design, firmware, cloud platforms, and mobile applications—often delivered by a single integrated team. Their work spans industrial IoT, medical devices, logistics platforms, and connected automotive systems, with a focus on compliance-driven environments (HIPAA, PCI DSS, ISO 27001, FDA).

Services and capabilities

Yalantis structures its offerings around four primary pillars: end-to-end IoT development (hardware design, embedded firmware, cloud integration, and mobile connectivity); embedded systems and firmware engineering; hardware design from schematics and PCB layout through production prototyping; and custom software (web, mobile, and cloud applications). They also provide data and AI services—implementing machine learning models for predictive maintenance and industrial analytics—and have recently positioned Rust adoption and consulting as a dedicated practice.

On the backend, they work with Java, .NET, Node.js, Python, Rust, and Go. Frontend capabilities include React, Angular, and Vue.js. Mobile development spans native iOS (Swift) and Android (Kotlin) as well as cross-platform solutions using Flutter and React Native. Cloud infrastructure integrates AWS (including RDS and IoT Core), Google Cloud, and Azure. For IoT and hardware, they handle PCB design, embedded systems, firmware, edge computing, and full-cycle device engineering. AI and ML work includes frameworks and big data processing.

They offer four engagement models: Time and Materials for projects with evolving scope; Fixed Price for defined requirements and deadlines; Managed Team for extending internal capacity with dedicated developers, designers, or project managers; and Managed Service for outsourcing entire functions like design, development, or QA. Additionally, they sell pre-built product accelerators (Yalantis IoT Accelerator, Yalantis Payments, predictive ML models for maintenance, authorization and DevOps kits) to reduce time to market.

Notable work

Yalantis has completed 200+ projects across multiple domains. A Dutch compressor manufacturer saw support requests cut in half and sales boosted through custom IoT and AI-powered predictive maintenance. For a medical device manufacturer, Yalantis built an AI-powered mobile app to connect ECG and pulse oximeter wearables with clinic systems across the US. A US logistics company received a custom vehicle fleet management platform with AI predictive maintenance capabilities. These engagements demonstrate delivery across both hardware-software integration and AI/analytics layers.

How they work

Yalantis employs a four-phase delivery model: Briefing (mapping vision to technical requirements), Prototyping (functional proof-of-concept for early validation), Design (user-centric, market-ready product design), and Implementation (secure software and compliant hardware). Teams use agile methodologies and maintain communication across time zones via Slack, Jira, and scheduled overlap meetings. They conduct in-depth discovery sessions upfront to define priorities, identify risks, and set realistic expectations. Post-launch, they provide ongoing maintenance, performance monitoring, and feature enhancements. Free initial consultations are offered to align on feasibility, timelines, and compliance requirements before engagement.

Team and credentials

Yalantis employs 400+ engineers across Poland, Ukraine, Cyprus, and Estonia. The firm holds ISO/IEC 27001:2022, ISO 9001:2015, and ISO 13485 certifications. They are a Raspberry Pi Design Partner and hold Advanced Tier status with Amazon (RDS and IoT Core delivery partners). Tech partnerships include Google Cloud and Azure. Client satisfaction metrics show a CSAT of 5.6/6, NPS of 91%, and an average collaboration term of 4+ years. They comply with HIPAA and HL7 for healthcare, PCI DSS and GDPR for fintech, and FDA guidelines for medical devices. Development follows OWASP and DevSecOps best practices.
