Who is Quartile for?

Built for investors who manage their own decisions.

Quartile is designed for a specific type of investor — sophisticated, self-directed, and managing wealth that has grown beyond the reach of retail tools.

Investable assets typically above $2 million — sophisticated enough to access institutional-quality deals, without institutional infrastructure.
The problem

The complexity has outgrown the tools.

A quarterly report arrives on Tuesday night. You read it carefully. Form a view. File it. What you can't easily answer is what your total exposure in that strategy actually is right now — across all your entities, across all your managers.

Capital calls arrive at inconvenient times. New deals need evaluation against a portfolio you can't see clearly. The alternative is a financial planner at $10,000–$25,000 a year, or a multi-family office that requires $10M+ just to get a meeting. Neither was built for this.

The platform

An investment committee in your pocket.

Structured decision-support and private markets analysis — built for the way self-directed investors actually work.

Know what you own.
Portfolio Dashboard
A single view across personal, SMSF and trust structures — bringing together asset allocation, capital commitments, income sources and portfolio health. Every entity, every month, in one place.
Analyse the deal, then analyse the fit.
Deal Room + Portfolio Impact
The centrepiece. A deal lands — upload the IM and the Deal Room delivers IC-grade analysis: scenarios, red flags, structural risks. Then Portfolio Impact shows what committing would do to your allocation, concentration and liquidity — measured against your actual holdings before you commit.
Your rules. Automated.
Guardrails
Self-selected allocation bands across every asset class. You set the ranges — the platform monitors them silently, flags breaches for your review, and maintains a permanent decision journal. Not advice. Your framework, your discipline.
Keep the people who matter informed.
Family Report
Every quarter, Quartile generates a plain-English portfolio summary and sends it to your spouse or partner. What you have, what came in, what's coming up, who to contact. Adapted to their financial literacy level. No other platform does this — and it resonates with every investor who has a partner who doesn't see the portfolio.
What Quartile is not

Designed to sit alongside the professionals you already trust.

Sophisticated investors often work alongside accountants, advisers, investment managers and fund managers. Quartile is not a replacement for any of them.

Instead, Quartile provides the investment intelligence and analytical infrastructure that helps self-directed investors understand what they own, assess new opportunities and explore how each decision may affect their broader portfolio.

It sits alongside the professionals you already trust, helping bring greater clarity, discipline and structure to the investment decisions only you can make.

Quartile IS

Institutional-style analysis and decision support

A tool that helps you engage with them more effectively

Quartile does not tell you what to invest in.

It helps you understand what you own, assess what you're considering, and explore how each decision may affect your broader portfolio before you commit capital.

"Six months in, the portfolio hasn't changed. What's changed is the feeling." — composure, not from ignoring risk, but from finally understanding it.

Why this exists

Built from the problem,
not the market.

"A new investment opportunity landed from a fund I trusted. I was ready to commit. Then I stopped — and realised I couldn't answer the questions that actually mattered. How much should I invest? What does this do to my overall portfolio — allocation, concentration, risk, income yield? Nobody had built the infrastructure for what self-directed investors at this level actually need."

This year the complexity outgrew the system — and nothing existed at the right level. Between a spreadsheet and a family office, there was nothing. So I built it.
