What CelLink does
CelLink Corporation is a Delaware-incorporated, venture-backed private company founded in 2012 by Kevin Coakley and Malcolm Brown, headquartered in San Carlos, California. The company designs and manufactures large-format, high-conductance flexible circuits that replace traditional wire harnesses, flexible circuits, and busbars with pattern-to-shape conductors carrying signals from milliamps to over 1,000 amps, delivering roughly 1/4 the weight and 1/10 the volume of conventional round-wire solutions while eliminating design-specific tooling. Its product portfolio centers on three platforms: the Current Collector Assembly+ (CCA+) battery pack interconnect integrating bussing, power cabling, voltage/temperature monitoring, and fusing into a single flex circuit; a broad Flex Harness product line spanning low- and high-voltage automotive, aerospace, defense, industrial, and stationary storage applications; and the CelLink PowerPlane, a flexible power circuit with integrated liquid cooling targeting hyperscale data center and AI factory power delivery in OCP-compliant architectures.
CelLink serves enterprise customers across two primary verticals — automotive/EV (passenger, commercial, and industrial vehicles; aerospace and defense) and data center/AI infrastructure (hyperscalers, OCP-compliant server manufacturers) — with secondary exposure to stationary energy storage. The company sells exclusively through a direct sales model with regional engineering offices in Wixom (Michigan), Hamburg (Germany), and Shanghai (China), and operates a major manufacturing facility under construction in Georgetown, Texas (the "MegaPlant"), partially funded by a $362M DOE ATVM loan. Over 3 million CelLink flex harnesses have been deployed in commercial EVs since 2020.
The revenue model is hardware sales of proprietary flexible circuit products priced via direct quote to OEMs, Tier 1 suppliers, data center operators, and industrial manufacturers; pricing is not publicly disclosed. Strategic equity from Lear Corporation (Series C lead, 2021), Whale Rock Capital (Series D lead, 2022), and numerous Tier 1 and OEM investors (BMW i Ventures, BorgWarner, Ford, Bosch, D1 Capital, T. Rowe Price, Fidelity, Franklin Templeton, among others) reflects deep commercial alignment with the automotive customer base. CelLink has raised approximately $315M in private capital alongside the $362M DOE loan, and is currently led by co-founder/CEO Kevin Coakley and co-founder/VP Engineering Malcolm Brown, with Karen Francis as Chair of the Board and Nancy Loewe as CFO.

CelLink product offering
Product offeringCore offering
CelLink designs and manufactures large-format, high-conductance flexible circuits that replace traditional round wire harnesses, flexible circuits, and busbars. Its products integrate power transmission, data signaling, voltage/temperature monitoring, and fusing into thin flat circuits, and are sold for EV battery interconnects, automotive wiring, data center power delivery, and stationary energy storage applications.
Product overview
CelLink offers a unified portfolio of large-format, high-conductance flexible circuit products organized around three core offerings: the Battery Pack Interconnect (CCA+ Platform) for EV battery integration combining bussing, power, sensing, and fusing; the Flex Harness for general power and data routing across automotive, aerospace, and industrial applications; and the CelLink PowerPlane specifically designed for data center AI factory power delivery with integrated liquid cooling. The company's technology replaces traditional wire harnesses and busbars with flat flexible circuits that deliver power and data at significantly reduced weight and volume.

CelLink competitors and assessment
Company assessmentBroad incumbents
- Lear Corporation: Global Tier 1 automotive seating and electrical systems supplier; lead Series C investor in CelLink and a major wire harness / electrical architecture incumbent. Lear competes directly in automotive electrical distribution where CelLink's flex circuits are gaining traction, and is also a strategic commercial partner through connector-system compatibility (HC terminals).
- Aptiv: Tier 1 supplier of vehicle electrical architecture, connectors, and high-voltage systems. Aptiv's HV connectors (BCON+) are listed as compatible with CelLink's flex harnesses, but Aptiv also represents the type of incumbent CelLink must displace as OEMs consolidate on zonal E/E architectures.
- Yazaki: Largest global wire harness manufacturer by revenue, deeply embedded across nearly every major automaker's electrical architecture. Represents the scale incumbent CelLink is competing against as it builds out flexible-circuit alternatives to traditional round-wire harnesses.
- Sumitomo Wiring Systems: Major Japanese Tier 1 wire harness and electrical systems supplier with extensive OEM relationships. Competes with CelLink in HV wiring and battery interconnects, particularly for Japanese and European EV platforms.
- TE Connectivity: Global leader in connectors, sensors, and electronic components with deep exposure to automotive, industrial, and data center markets. TE's BCON+ HV connectors integrate with CelLink's harnesses, but TE also sells competing flexible-circuit and power-distribution products into the same end markets.
- Amphenol: Diversified interconnect, antenna, and sensor manufacturer with strong positions in automotive, data center, and industrial markets. Amphenol's Radsok connectors are listed as OCP-compatible with CelLink's PowerPlane, while Amphenol itself competes in high-current power delivery for AI infrastructure.
- Molex: Global electronic solutions manufacturer offering connectors, cable assemblies, and increasingly flexible-circuit and power-delivery products. Molex's through-hole connectors are compatible with CelLink's harnesses, and Molex overlaps in automotive and data center interconnect markets.
Direct peers
- Multek (Multek / Flexium / M-Flex): Specialist flexible circuit and rigid-flex PCB manufacturer serving automotive, consumer electronics, and industrial customers. The closest direct comparator to CelLink in flex-circuit manufacturing technology, although Multek does not focus on high-current EV battery interconnects or AI data center power delivery.
- TTM Technologies: Major PCB and flexible circuit manufacturer with automotive, aerospace, and data center exposure. TTM represents a scaled flex-circuit competitor that could pursue the same EV battery interconnect and high-current power delivery opportunities as CelLink.
Others
- DuPont: Materials supplier into the flex-circuit ecosystem (copper-clad laminates, flexible substrates, and Pyralux). Not a direct competitor but an enabling supplier whose materials roadmap influences CelLink's manufacturing economics and capability ceiling.
