Started as a Substack draft in early 2024, VoltageDesk now lands in 31,400 inboxes every weekday at 6:15am ET. The editorial system pulls overnight pricing, FERC filings, EIA data, and trade press, drafts in long-context GPT-5, and runs a Claude editor pass before send. The founder approves the lede; everything else ships untouched. Sponsorship slots — currently 11 of 12 sold — go to grid software vendors and battery developers who want desk-level distribution. Conversion from free to $49/mo paid sits at 4.2%.
