They Found the Market in Their Own Traffic Spikes: Microgrid Knowledge's 7-Figure, Multi-Bid Exit
Three energy journalists noticed that their microgrid articles were being read at an unusual rate and launched a specialist media outlet in 2014. It grew to 40,000 subscribers and high 7-figure annual revenue (approaching ¥1 billion). With four revenue streams — media, an annual conference, and content production services — it was sold to Endeavor in 2022 after a multi-bid process.

The Business Timeline
| Period | Event |
|---|---|
| Up to 2014 | Three people (including editor-in-chief Elisa Wood) co-ran an energy-efficiency media outlet. They noticed that “whenever we write about microgrids, traffic always spikes” |
| 2014 | Microgrid Knowledge launched |
| 2016 | Annual conference started |
| April 2022 | Sold to Endeavor Business Media (90 outlets, 60 conferences, 700+ staff) for 7 figures. Multiple bids |
The Numbers (at Sale)
| Item | Figure |
|---|---|
| Annual revenue | High 7-figures (approaching ¥1 billion) |
| Email subscribers | Over 40,000 |
| Annual unique visitors | 375,000 |
| Sponsors | Over 100 companies |
| Team | 3 founders plus around 6 contractors |
The revenue had evolved into four pillars: (1) online media (advertising and sponsorships), (2) an annual industry conference, (3) content production services for companies, and (4) a policy advocacy organization. What drove the multiple bids and high valuation was that they owned not just a media outlet, but the industry’s entire central function.
Reading Between the Numbers
Their method of market discovery is a perfect, repeatable playbook. Watch per-article traffic on an existing media property, then spin out the sub-topic that gets an unusually strong response into its own standalone outlet. Microgrids went on to become a $30 billion industry, and the head start they had accumulated became, in Wood’s words, a “barrier to competitors.” Your own blog’s analytics are the research data for your next business.
B2B media is valued not on pageviews but on how completely it monopolizes an industry function. 375,000 annual visits is nowhere near the 4.5 million monthly visits of a consumer site, yet annual revenue approached ¥1 billion — an entirely different order of density. A media outlet that owns the conference where industry insiders gather once a year can sell not ad slots but access to the industry itself.
Three equal partners lasting eight years is remarkably rare. Wood’s advice: “In the early days, above all, patience. And get good partners.” Alongside the four founders of Really Good Emails and the couple behind EventMB, the long game of content businesses shows that dividing skills across multiple people improves survival rates.
