Mesa CPA started as a small bookkeeping firm in Toronto. By client #80, we had a problem: the same closing checklist every month, on every set of books, with the same handful of issues hiding in the same handful of places. Reconciliations slipping. Duplicates. Suppliers coded to the wrong account. AR aging out quietly.
We tried the obvious things. More bookkeepers. More checklists. Color-coded spreadsheets. Slack reminders. None of it scaled — not because our team wasn't good, but because the work itself doesn't scale: every client's books change every day, and humans can only reasonably review every few weeks.
So we built the thing we wished existed. A small program that would log into every QuickBooks account every night, run our entire checklist, and show us — by 7am — exactly which clients needed attention.
We named it Argus, after the hundred-eyed giant from Greek myth — the one Hera assigned to watch Io because no human had enough eyes for the job. The name turned out to fit.
We ran it on Mesa's own client base for eighteen months before we showed it to anyone else. Other firms saw the dashboard. Then their clients saw it. Then the clients asked if they could keep using it after they stopped working with us. That's how Argus stopped being a firm tool and started being a product.
Most accounting tools eventually become accounting platforms. We're trying very hard to stay one thing, done well.
We're not a venture-funded growth team. Argus is run by a handful of people, half of whom are currently signing off month-end packages.
Builds the product. Co-founded Mesa CPA before this. Spent more time inside QuickBooks than is medically advisable.
Runs Mesa CPA's accounting practice. Designed the original checklist that Argus is, essentially, automating.
Scales the product into firms. Runs Bottom Line Company on the side. Will probably be the first person who replies to your email.
Owns the rule engine and the AI layer. If Argus flags something, he probably wrote the heuristic — or trained the model that did.
Argus is profitable on Mesa CPA's customer base alone. Every dollar of growth is a dollar earned from a paying customer — not a runway extension. We think it's the right shape for a tool that sits inside other people's books.
