Blues, a Boston-based company specializing in secure Internet of Things connectivity, has secured a total of $33 million in funding this year to accelerate development and go-to-market efforts. This includes a $25 million round in May 2025, led by Sequoia Capital, and an additional $8 million in follow-on capital announced in July. The latest investment signals sustained investor confidence in Blues’ platform as demand grows for embedded connectivity in smart products.
Blues builds solutions designed to help companies connect physical products to the cloud without the traditional complexity of building custom infrastructure. Its two flagship offerings—Notecard, a low-power hardware module, and Notehub, a global device management and routing service—enable developers to easily embed cellular, Wi-Fi, or LoRa connectivity into devices and route data securely to any cloud endpoint.
The company was founded by Ray Ozzie, former Chief Software Architect at Microsoft and creator of Lotus Notes, and has steadily positioned itself as a go-to platform for enterprises seeking fast, secure, and scalable ways to deploy connected products. Blues’ modular approach eliminates many of the barriers to IoT adoption by offering pre-provisioned cellular service, baked-in security, and intuitive APIs that work out of the box.
CEO Ian Small stated that the new capital will allow the company to meet rising customer demand in logistics, medical cold chain monitoring, EV battery tracking, and other sectors where secure connectivity is critical. The funding will also fuel continued investment in platform development, especially as customers seek more intelligence at the edge.
With nearly $100 million in total funding since its inception, Blues is building a vertically integrated stack that addresses connectivity, device management, and security—all areas that have traditionally required separate vendors or significant custom development. By offering a single solution that scales from prototype to production, Blues is becoming an enabler for digital transformation in traditionally offline industries.
The recent follow-on round from XYZ Venture Capital reflects strong early traction from customers and signals confidence in the company’s long-term potential. The capital will go toward growing the team, expanding global deployments, and enhancing the platform’s flexibility for industries with complex infrastructure and compliance requirements.
Blues is not just betting on the proliferation of smart devices—it’s positioning itself as the infrastructure backbone that helps developers and enterprises build, secure, and manage those devices at scale. Its solutions are already in use across a wide range of applications, from tracking refrigerated vaccines in remote regions to managing industrial sensors and consumer health devices.
Roelof Botha, who joined Blues’ board as part of the Sequoia-led investment, brings deep operational and scaling experience that aligns with Blues’ ambition to become a core utility for physical-to-digital transformation.
As more industries digitize their operations and seek to leverage real-time data from connected products, Blues offers a platform that promises to lower friction and raise security standards. This funding round cements its role as a key player in the next wave of IoT innovation.
