Institutional wealth governance. Without the institution. Optimal Financial brings family-office-grade oversight to anyone serious about their wealth, whether you're managing $50K or $50M. See every account, holding, and entity in one governed view, and understand not just what you own, but how well it's structured. ONE VIEW OF EVERYTHING Bring 4,000+ banks and brokerages into a single dashboard: equities, cash, fixed income, alternatives, and digital assets, in any currency. No more spreadsheets, no more logging into ten portals. A GOVERNANCE SCORE, NOT JUST A BALANCE Most apps show you a number. Optimal Financial shows you a verdict. Your Governance Score rates your wealth across the dimensions that actually matter (concentration risk, investment policy, structure, and more) so you can see where you're exposed and what to fix. It's the discipline an institution applies to its capital, applied to yours. BUILT-IN COMPLIANCE OVERSIGHT Track FATCA and CRS exposure, beneficiary structures, and trust arrangements in the same place you track your portfolio. For families and advisors carrying cross-border reporting obligations, the governance and the compliance picture finally live together. AI-POWERED INSIGHTS Ask plain-language questions about your portfolio and get answers grounded in your own data: your concentration, your gaps, your structure. Insight, not generic tips. BUILT FOR THOSE WHO TAKE STEWARDSHIP SERIOUSLY - Serious individual investors who want institutional rigour - Family offices managing multiple households - Trust companies, IFAs, and advisors who need oversight, not just aggregation PRIVATE BY DESIGN Your data is hosted in a non-US jurisdiction on Canada-based infrastructure, with bank-level encryption.
