The gap is rarely the system. It is what happens around it.
Adjacent Works builds focused tools that run alongside the software a business already depends on, rather than asking it to move.
A replacement is expensive to buy, slow to roll out, and risky to reverse. That cost is why so many real problems go unsolved: the fix is not worth a migration, so the workaround becomes permanent and somebody absorbs it by hand every week.
Working adjacent to a system changes that arithmetic. A narrow tool can read what is already there, do one job carefully, and be abandoned without consequence if it turns out to be the wrong idea. That is a much easier thing to try, and a much easier thing to be honest about.
