Silicondust USA

What Silicondust USA does

Silicondust USA, Inc. is a privately held California corporation founded in 2007 that designs, manufactures, and sells the HDHomeRun line of network-attached TV tuners. The company's core technology captures over-the-air (ATSC 1.0 and ATSC 3.0), QAM, and international DVB-T/T2/C broadcast signals at the antenna and streams them over Ethernet or Wi-Fi to viewing devices throughout a home network, with whole-home DVR functionality enabled through attached USB storage or third-party NAS devices. Product breadth spans consumer FLEX tuners (priced $109.99–$199.99, with a $299.99 developer variant), commercial TECH-series rackmount tuners ($499.99–$3,000) for enterprise multicast IPTV, the HDGrandSlam MDU TV system ($18,000 with recurring $1,000/year service) for hotels and apartment buildings, and an antenna line acquired through the 2021 HD Frequency acquisition.

The company's revenue model combines one-time hardware sales (consumer, commercial, MDU, accessories), an annual HDHomeRun DVR software subscription for recording functionality, and recurring service fees on MDU deployments. Go-to-market is plural: a product-led growth consumer motion through direct e-commerce and marketplace listings (Amazon, eBay, Newegg, Walmart); an enterprise field-sales motion targeting hospitality, MDUs, educational institutions, and broadcast outlets; and adjacent infrastructure offerings (ATSC3 Certificates, BEST CDN) for broadcasters. International DVB variants extend the addressable market to the EU, UK, Australia, and New Zealand. The HDHomeRun platform integrates with major third-party media applications — Plex, Emby, Channels, Windows Media Center — and supports DVR storage on NAS devices from Western Digital, QNAP, Synology, Asustor, and FreeNAS. The company lists Theodore Head as CEO and President and Nick Kelsey, an experienced software and embedded systems engineer, as Founder and CTO; it is privately held with no disclosed venture capital or institutional funding.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• Tablo (Nuvyyo): Tablo is the most direct competitor to HDHomeRun — a network-attached OTA DVR with whole-home streaming and subscription DVR service, built specifically for US/Canadian cord-cutters. Same core product category, same customer pain points, same Amazon/Newegg retail presence.
• AirTV (EchoStar/Dish): AirTV is a network OTA tuner launched by EchoStar/Dish Network, bundling Sling TV streaming with free local broadcast TV. Direct overlap with HDHomeRun's network-tuner-for-cord-cutters proposition, with the strategic twist of cross-selling into Dish's satellite TV subscriber base.
• Channel Master: Channel Master manufactures OTA DVR devices (Channel Master DVR+) and a broad antenna lineup, competing head-to-head with HDHomeRun hardware. Same retail channels (Amazon, Newegg) and same cord-cutter value proposition; HD Frequency's antenna line is a direct vertical overlap.
• Hauppauge Digital: Hauppauge is a long-standing TV tuner hardware maker (PC tuner cards, USB tuners, WinTV product line). Overlaps with HDHomeRun's TECH/legacy consumer tuner category, including ATSC 3.0 tuners and commercial/headend applications.

Broad incumbents

• TiVo (Xperi): TiVo (now an Xperi business) is the legacy DVR brand spanning consumer set-tops, IPTV guides, and connected-TV platforms serving operators and broadcasters. A broader incumbent that overlaps with HDHomeRun's DVR subscription service in the cord-cutter/OTA DVR mental model but operates across a much wider DVR/services portfolio.
• Roku: Roku dominates the streaming-device category and increasingly absorbs live/linear TV functionality (The Roku Channel, Live TV guides). Competes for the same household TV-viewing time and retail shelf space as HDHomeRun, and represents the primary alternative device category cord-cutters compare against.

Emerging players

• Slingbox / EchoStar: Slingbox was EchoStar's network-attached place-shifting device for live TV — same conceptual category as HDHomeRun (networked TV tuner/streaming hardware) before its discontinuation. EchoStar also owns AirTV; comparable technology roots and operator-backed go-to-market.

Others

• Plex: Plex is a core technology integration partner of HDHomeRun for live TV viewing and DVR management, but Plex is also a competitive adjacent media-center platform with its own streaming/DVR ecosystem. Dual relationship: partnership + adjacent platform competition for end-customer wallet share.
• Emby: Emby is a third-party media server platform that natively supports HDHomeRun live TV integration. It is both a published integration partner and an adjacent ecosystem serving the same cord-cutter/whole-home DVR use case.
• Winegard: Winegard is a leading US OTA antenna and signal-accessory manufacturer. Adjacent via Silicondust's HD Frequency-branded Cable Cutter antennas and LTE filters, and the same fundamental OTA equipment customer base.
