How a Former Tech Executive Built a Profitable Business Using Old Maps

Craig Campbell spent years building systems at Meta, one of the world's largest tech companies. In 2022, he made an unusual choice: he walked away from offers to fund AI projects and instead started a business around something much older—historical maps.

His company, called Past Maps, lets people search for and view maps from the past. The customers are genealogy researchers tracing their family trees and industrial companies looking for historical records of old oil wells. These users need maps from specific time periods—sometimes decades or even centuries old—that aren't available on Google Maps or Apple Maps.

Past Maps makes money by charging these customers for access to this historical data. And unlike many technology startups that burn through investor cash in hopes of growing quickly, Campbell's business is actually profitable without any outside funding.

Why Walk Away from AI Money

In 2022, investment money was pouring into artificial intelligence projects. Every tech investor wanted to fund the next big AI company. For someone like Campbell—with engineering credentials from Meta—funding would have been easy to get.

Instead, he chose to focus on a specific problem that many people overlook: the need for accurate historical maps. This decision stands out because it goes against the current trend. Most ambitious engineers chase the big, flashy opportunities. Campbell bet on something smaller and more stable.

The broader context here is that this isn't entirely new thinking. During the dot-com boom of the late 1990s, narrow, focused businesses often survived while broad consumer-facing platforms collapsed. The same pattern played out in the smartphone app world—most of the lasting value came from targeted, useful tools rather than apps trying to be everything to everyone. Campbell may simply be following a pattern that surfaces again and again: success often comes from solving a specific problem very well, not from building something massive.

A Niche with Real Demand

Genealogy research is bigger than most people realize. Companies like Ancestry.com are publicly traded and consistently profitable. Millions of people want to trace their family history, and many are willing to pay for accurate information to do it.

Oil and gas companies also need historical maps. When a company wants to drill or explore in an area, it needs to know what was mapped and recorded there fifty or a hundred years ago. Modern satellite mapping is useful, but it doesn't show what humans recorded in the past. A human researcher working from historical documents can find things that algorithms cannot easily replace.

Campbell built his service as a straightforward website. You go there, search for the maps you need, and access them. The technical foundation—how the maps are stored, how the search works—isn't the main point. The value is in having the historical data organized and easy to find.

A Different Kind of Success

Most venture-backed technology companies spend investor money faster than they make it, betting that they will eventually grow so large that profits will follow. Past Maps is the opposite. It makes money from day one, serves a clear set of customers who will pay for what it offers, and doesn't require massive growth to remain viable.

This approach works because the problem is specific and the customers are willing to pay. It also sidesteps one of the biggest challenges facing young tech companies: the pressure to grow at any cost, even if growth burns money you don't have.

Campbell's background at Meta—a company obsessed with scale and growth—may actually have equipped him to appreciate the value of a smaller, more focused business. After years in that world, building something profitable and sustainable can look attractive.

What This Tells Us

Past Maps is not a household name and probably never will be. It won't disrupt entire industries or change the world. But it does show that profitable technology businesses can exist outside the usual venture capital funding cycle. You don't need massive investment or explosive growth to build something valuable.

For experienced engineers, especially those who have worked at major technology companies, there are opportunities in solving concrete problems for specific groups of people. These opportunities are usually quieter, smaller, and less glamorous than chasing the next big trend. But they can be more stable and, in this case, more immediately profitable.
