Microgrid Knowledge: 3 Journalists Turned a Traffic Anomaly into a Seven-Figure Exit

Where do you find the theme for your next business? Microgrid Knowledge’s answer was: your own media property’s analytics. Three journalists running an energy-efficiency outlet noticed one anomaly, “only the articles about microgrids get read at an abnormal rate”, and spun off a specialist publication in 2014. Over eight years they grew it to 40,000+ subscribers and revenue in the high seven figures (approaching $10M), before selling to B2B media giant Endeavor Business Media in 2022 after a multi-bid process. It’s a rare case where every stage, from discovering the market to diversifying revenue to choosing the exit, is documented in numbers and the founders’ own words.

A hurricane taught them the market

It started with Hurricane Sandy in 2012. Amid the widespread blackouts on the U.S. East Coast, microgrids (small, independently operable local power networks) came into the spotlight, and editor Elisa Wood recognized the theme’s future potential. At the time, Wood and her colleagues were writing for an energy-efficiency outlet called Energy Efficiency Markets, and they’d repeatedly observed that traffic spiked specifically on articles that touched on microgrids.

A second signal came from someone close to home. When Kevin Normandeau, who ran the publishing side, kept asking the same question, “what exactly is a microgrid?”. Wood recalls that “a lightbulb went off.” A demand signal locked in by reader data, plus a knowledge gap so wide that even industry insiders didn’t know the basics, where these two overlapped, Wood, Normandeau, and Lisa Cohn launched Microgrid Knowledge in 2014.

Eight years, on a timeline

A snapshot at the time of sale

Revenue had evolved into four pillars: (1) online media (advertising, sponsorships), (2) an annual industry conference, (3) content-production services for businesses, and (4) a policy-advocacy organization. Owning “the industry’s central function” as a whole, rather than the media property alone, is the source of the multi-bid interest and high valuation.

The early days: “we got here before the industry did”

The reality right after launch was harder than the traffic-spike discovery story suggests. Wood says “the early days were just brutal, really hard.” The microgrid market hadn’t taken shape yet, and every article had to explain the concept to readers before delivering the news. The publication and the industry had to be built up simultaneously, and the founders kept it alive by supplementing income with freelance writing and consulting.

The turning point was the 2016 annual conference. By hosting a once-a-year gathering for the scattered operators, municipalities, and researchers themselves, Microgrid Knowledge transformed from “a media outlet distributing information” into “the industry’s connective node.” Sponsors eventually topped 100, and the microgrid market itself grew into a roughly $30 billion industry. The readers, data, and relationship capital they built up early became, in Wood’s words, a barrier against competitors.

Reading behind the numbers

The market-discovery method doubles as a replicable playbook. Watch per-article traffic on an existing media property, and spin off the sub-theme that reacts abnormally into its own outlet. It didn’t start from a hunch or a market research report. It started from their own readers’ behavior logs. They even backed it up with a qualitative signal: “supposedly knowledgeable insiders were asking basic questions.” Your own blog’s analytics are the research data for your next business.

A B2B media property gets valued not on pageviews but on “how much of an industry function it monopolizes.” 375,000 annual visits is far short of the consumer-side 4.5 million monthly, yet annual revenue was an order of magnitude more concentrated, approaching $10M. A media outlet with a conference, “the place the industry gathers once a year”, can sell not ad inventory but access to the industry itself. That the acquirer, Endeavor, is a company that bundles 90 publications and 60 conferences is circumstantial evidence that the buy side, too, was valuing this “media + event” combination.

The rarity of a three-way equal partnership lasting eight years. Wood’s advice: “patience early on, above all. And find good partners.” The division of labor (editorial (Wood), publishing operations (Normandeau), writing (Cohn)) paid off both in enduring the pre-revenue years and in the capacity to run four pillars in parallel. Alongside Really Good Emails’ four founders and EventMB’s founding couple, content businesses that survive the long haul tend to lean on multi-person division of labor by function.

Victims of their own success — inside the sale

Wood describes the motive for selling as “we were victims of our own success.” A team of three founders plus six contractors couldn’t keep up with the industry’s rapid growth, and “it had become rare to get a weekend off.” Keep expanding on their own with outside capital and staff, or hand it to an organization that could scale it. They chose the latter.

Multiple candidate buyers surfaced during the sale process, and Wood describes the process itself as “stressful.” What ultimately decided Endeavor wasn’t price alone, but “the ability to grow the publication” and a fit with the company’s existing family of energy-sector brands. Founded in 2017, Endeavor is a roll-up company for B2B media with conference-operating capability of its own, a buyer with a home for every pillar of the business: media, events, and production services.

After the sale, the three founders’ paths diverged. Wood founded a subscription community, “Energy Changemakers”; Normandeau stepped back to help launch a financial-literacy nonprofit for former foster youth. And Cohn runs her own independent venture, Clean Energy Writers. That all three could move on to “what’s next” in the same field shows that eight years of expertise remained as a personal asset, separate from the media property as a corporate asset.

What’s reproducible, and its limits

The market-discovery method generalizes. Find a sub-theme that gets an abnormally strong reaction in your own output’s analytics, and spin it off. The same move works with a Japanese blog or a YouTube channel. Positioning yourself ahead of the curve as “the primer” during an industry’s formative period is also a pattern shared with Green Market Report, which capitalized on a reporting gap in the cannabis industry.

Revenue scale, on the other hand, depends on the environment. The approach-to-$10M revenue was underpinned by the depth of the English-language B2B advertising/sponsorship market and a conference economy with 100+ sponsors, not a figure that transplants directly onto a comparably-sized niche in Japan. Another hard-to-reproduce point is the team structure. The three founders crossed the 2014-2016 valley before the market existed, on outside income and patience. Even with the right theme, without this “design for surviving the pre-revenue period” (outside income, multiple people, low fixed costs), you won’t get the same curve.
