How to find a reliable IoT software developer?

This question is especially acute due to the widespread adoption of Internet of Things technology. Its popularity has led to the growth of companies offering IoT software development services, creating a challenge in finding the right development partner.

Here’s a look at the top companies in 2026 that provide IoT software development services, along with SumatoSoft’s IoT offering, that we meticulously analyzed and selected for this article.

What is IoT development?

IoT development involves creating interconnected devices, systems, and services that leverage IoT technology. IoT pertains to the expanding network of objects that communicate and share data over the internet. The development process encompasses embedded systems engineering, software development, data analysis, and network security.

By implementing IoT solutions, companies can improve efficiency, elevate customer satisfaction, and unlock revenue opportunities across sectors such as smart cities, healthcare, agriculture, and manufacturing.

How IoT development brings a competitive edge

The development of IoT offers businesses an advantage by enabling them to leverage devices, systems, and services to enhance operations and deliver better customer experiences. By leveraging IoT, companies can collect real-time data, automate tasks, and base decisions on data analysis rather than intuition or gut feeling. 

This opportunity helps them cut costs, improve IoT ROI, reduce downtime, and boost product quality. Additionally, IoT empowers businesses to innovate their products and services, creating opportunities for new revenue streams and business models. By embracing IoT development, companies can set themselves apart from competitors and maintain a leading position in the market or in their respective industries.

IoT trends in 2026

In 2026, several IoT trends shape how companies plan and build solutions:

• Edge AI and on‑device analytics reduce latency and cloud costs while improving resilience.
• 5G and private industrial networks enable reliable, low‑latency connectivity for factories, logistics hubs, and smart cities.
• Interoperability standards, such as Matter in smart home ecosystems, simplify integration between devices from different vendors.
• Combining IoT with large language models and virtual assistants improves usability through natural‑language control, smarter dashboards, and more intuitive interfaces.

How much does IoT development cost?

It typically costs $25–$99 per hour to hire an IoT development team, with many providers clustering in the $50–$99/hour range. More premium teams can charge $100–$149/hour, and top-tier consultancies may go as high as $200–$300/hour.

For project budgets, the most common minimum engagement starts at around $10,000, while some providers set a higher floor at $25,000, and premium consultancies can require $250,000+ as a minimum.

As a result, a small IoT MVP typically starts at $10,000–$25,000, and end-to-end IoT solutions (device connectivity + backend/cloud + dashboards/analytics + security and ongoing support) scale significantly depending on hardware/firmware work, integrations, compliance requirements, and long-term maintenance.

How long does IoT development take?

Simple IoT solutions, such as basic smart home setups or single‑purpose devices, usually take from 3 to 6 months to design, build, and test. Industrial platforms, connected healthcare systems, or city‑scale deployments often require 6–18 months, including hardware-software integration, security and compliance work, and staged rollouts.
