New funding will drive mass market commercialization for ultra-energy efficient, UWB-based wireless electronic devices and sensors

Montreal, Canada, March 13, 2023 – SPARK Microsystems, a Montreal-based fabless semiconductor company specializing in next-generation ultra-wideband (UWB) wireless communications, today announced the closing of CDN$34 million Series B financing, with an additional CDN$14 million available subject to meeting operational milestones. Led by Idealist Capital, a prominent investment firm focused on the energy transition and decarbonization, the round includes existing investors Cycle Capital, Economic Development Canada (EDC), Real Ventures, and ND Capital.

This round of investment extends the company’s resources to deliver on its mission to transcend the performance, power, and sustainability limitations of legacy short-range wireless platforms. Proceeds will be used to accelerate customer acquisition and partner engagements, as well as product development for major markets spanning mobile electronic devices and smart sensors. SPARK’s ultra-low power, low latency, high data rate wireless UWB transceivers enable new levels of functionality and performance with no compromises for a broad range of consumer, industrial, IoT, and automotive products.

“With strong backing from Idealist Capital and existing investors, SPARK Microsystems is well positioned to execute on its vision of creating high-performance wireless networks for a broad range of products with significantly longer battery lifecycles and reduced waste for a more sustainable, environmentally friendly future,” said Fares Mubarak, CEO, SPARK Microsystems. “This new financing marks a pivotal milestone in the mass market commercialization of SPARK’s UWB technology, equipping us to meet massive demand for breakthrough performance in short-range wireless connectivity.”

“Idealist Capital embraces investment opportunities in innovators like SPARK Microsystems who developed a breakthrough technology to enable greener, energy efficient electronic devices without compromise in performance,” said Steeve Robitaille, Co-Managing Partner, Idealist Capital. “We are thrilled to support SPARK for its future growth. SPARK’s UWB technology holds tremendous promise for battery-less, wireless devices powered by energy harvesting technologies.”

“We’re pleased to see a new investor join the company and share our belief that Spark’s cutting-edge technology can enable a significant energy consumption reduction in a wide range of applications. This financing will help accelerate the deployment of Spark’s next-generation ultra-wideband technology on a global scale,” said Andrée-Lise Méthot, Founder and Managing Partner at Cycle Capital. “We look forward to contributing to SPARK Microsystems’ growth as we are convinced the team has developed an industry leading product that will enable electronic devices to be more energy efficient.”

SPARK Microsystems’ UWB short-range wireless technology dramatically reduces energy consumption for connected devices. Its performance attributes are essential for enabling the next generation of wireless connected mobile devices and sensors optimized for high energy efficiency, driving a significant reduction in battery usage and replacement. Among its recent milestones, SPARK has expanded its collaboration with industry standards organizations (IEEE, UWB Alliance, FiRaTM Consortium) and built a global sales and distribution network while winning accolades and investments from Sustainable Development Technology Canada (SDTC) for improving energy efficiency in wireless devices. SPARK transceivers – complemented with SDKs and reference designs – are designed into customers’ next-generation products in consumer and IoT sensor markets, with strategic engagements in progress with tier-one technology suppliers.
