Why it matters

Pastmaps shows how a solo founder can use AI as operating leverage: not to replace the product, but to turn a hard-to-search archive into distribution, retention and revenue.

The best way to understand Pastmaps is the 52-minute gap on July 24, 2025.

At 10:40 p.m., Craig Campbell posted the kind of founder update that makes the grind feel temporarily sane: Pastmaps, the historical mapping app he had been building for two years, was now grossing more than $100,000 a year.

"It's been painful. And I've felt mostly like a crazy person."

Then came the milestone: "Pastmaps is now grossing over $100K / year." The next goal was $1 million a year. Solo.

At 11:32 p.m., the feed snapped back to startup physics. On the heels of the announcement, Campbell said he had received a bug report that Pastmaps maps were loading as blank white spaces for Safari users. He had apparently introduced the root cause two months earlier. "Humbling. embarassing. and unfortunately not that surprising."

That sequence is the company in miniature: the celebration, the bug report, the public post-mortem, the next thing to fix.

Campbell's Threads profile describes him plainly: "Solo founder, Engineer, History nerd," building @past.maps, "Google maps but for old maps." The same profile lists him as a 3x founder, ex-Facebooker, based in Seattle, with 14.8K followers and 371K recent views at the time of export.

Pastmaps is a strange and specific thing: historical maps overlaid on the modern world, wrapped in tools for genealogists, metal detectorists, urban explorers, writers, GIS professionals, and anyone trying to answer a deeply local question about what used to be somewhere. Its origin is even more specific. Campbell says he built it for himself as an avid hobbyist metal detectorist, using historical maps, LiDAR, satellite imagery, and other layers to locate long-forgotten places around him. He opened it up, and Pastmaps was born. His takeaway: building for your own obsession is a "cheatcode" to product-market fit.

The mission came earlier, in January 2024: "making history accessible to everyone." Historical research, he wrote, is hard. The data sits in "s3 buckets, ftp servers, and private/govt collections." Search and discovery tools barely exist. Collaboration loops are missing. "I'm building all of the above," he wrote, "or at least trying to."

The timeline

The Pastmaps story starts with a founder unsure what to post.

July 2023: Campbell begins using Threads as a public build log. On July 6, he says he is unsure what to write because Twitter had been where he talked about products and companies, while Threads felt closer to his real-life friend graph. Four days later, a single Hacker News comment about Pastmaps and its client-side tiling approach drove his best signup day yet. He took the lesson: maybe marketing could be as simple as talking about the work.

September 2023: Pastmaps becomes profitable for the first time, helped by physical map print orders. The print business was only about three weeks old and looked like it could drive $200-$300 a month. A few days later, another order raised the estimate.

January 2024: The mission gets sharper. December metrics show 15,200 users, 65,000 pageviews, and $2,223 in non-recurring revenue. Campbell says he has been forgoing salary and "maniacally building Pastmaps from the ground up" because the product needs to exist.

March-April 2024: Pastmaps crosses 30,000 MAUs, then 10,000 registered users. In April, Campbell writes that March brought 35.1K MAUs, 131K pageviews, and $1,875 in non-recurring revenue. His April goal is almost comically small and dead serious: "Make $1 in recurring revenue." By April 21, three days after launching Pastmaps+, he has three subscribers and $36 in MRR.

August 2024: The product starts to feel alive. Pastmaps crosses 200 active paid subscribers. A LiDAR launch helps drive all-time highs across DAUs, search traffic, pageviews, signups, paid membership signups, and premium conversion. Campbell posts that revenue grew 65% month over month to $6,600, with churn down 29%, customers up 30%, and MAUs up 7%. His next goal: $8,333.33 in monthly revenue, enough to prove a six-figure run rate.

December 2024 / January 2025: He hits the exact goal almost to the dollar. December revenue lands at $8,341.77. MAUs hit 56.1K. Active paid subscribers reach 300. In a self-assessment, Campbell gives himself an A for the revenue goal, a B for MAUs, and an F on making Pastmaps "the best historical map product on the web." Overall grade: C....
