Technical White Paper Campaign
CorePower Magnetics
CorePower Magnetics is a venture-backed advanced magnetics manufacturer developing high-performance inductors, transformers, and magnetic materials for AI data centers, grid modernization, and next-generation electrification systems. Backed by the U.S. Department of Energy and Department of Defense, the company is advancing U.S.-manufactured magnetics designed to improve efficiency, reduce supply chain risk, and enable emerging high-voltage power architectures.
Challenge
High-power, medium-frequency inductors had always been custom-built. No standardized off-the-shelf solution existed for applications requiring 50 to 300A at 10 to 100 kHz - leaving engineers dependent on long custom design cycles, limited model availability, and high NRE costs.
CPMLMAX was the first standardized inductor product to fill that gap. The white paper was designed to establish that market position with technical credibility, educate a highly specialized buyer audience across AI data centers, grid, EV charging, and aerospace applications, and generate qualified leads in the process.
Solution
I authored the white paper and owned end-to-end campaign strategy, content development, and execution.
White paper content included market gap analysis, sector-by-sector application breakdown, nanocrystalline vs. powder core performance comparison, inductance stability under bias current, and standardization as a procurement and design strategy.
Campaign execution included:
Three audience segments with distinct landing pages: general, investor, and gated
Two-touch email campaign with A/B subject line testing
Follow-up send to unopened contacts with cold company exclusion to protect deliverability
LinkedIn organic post with gated form
Short and long-form campaign video production
