BankDeMark: rank #1 with tools, not tricks.
BankDeMark is a Canadian finance platform built on a simple thesis: interactive calculators earn search rankings that articles alone can't. We architected 91 URLs around 13 calculators and the content that feeds them — then engineered the financial layer underneath with the rigor money demands. Every number below is sourced and dated.
Position 1.3
#1 on its head query
Google Search Console, 180-day window ending Aug 12, 2026: the net-worth-by-age page holds average position 1.3 (332 impressions), retirement-savings-by-age sits at 2.3, and the calculators hub at 2.6.

Perfect Lighthouse
Accessibility 100, Best Practices 100, SEO 100 — measured by us with Chrome Lighthouse (mobile) on Aug 12, 2026. Not an estimate; a run you can reproduce.
91 URLs
Calculator-led architecture
13 interactive financial calculators, ~58 articles, and 9 pillar pages engineered as one internal-linking system — tools earn the rankings, content converts the intent.
26 test cases
Golden financial cases
Money math is tested against golden cases — plus ~190 automated tests across the platform's financial kernel, with money-precision handling built to the cent.
26 tables
Row-level security everywhere
The financial data layer runs 26 Supabase tables, every one RLS-enabled, with tracked migrations and an append-only audit trail.
3 subdomains
One financial system
bankdemark.com (public platform), command.bankdemark.com (business finance app), invoice.bankdemark.com — one entity graph, one brand, scoped cookies.
The honest part
BankDeMark is young and pre-revenue, and its business-finance product layer is in active development — we publish that plainly. What's proven today is the search architecture (a #1 position on a competitive head query within months of launch), the measured technical ceiling (a literal perfect Lighthouse score), and an engineering culture where financial math ships with golden test cases and the internal audits are harsher than anything a client would write. Rankings come first; the clicks and revenue curve are what the next chapter measures.
