Chief Financial Officer

Seventh Street Ventures • Full-time • Sydney, NSW, AU • 1d ago

You don’t just read financials. You use them to decide what to build, what to buy, and what to sell.

Lead finance across a dominant childcare SaaS platform and a multi-company venture studio
Capital raises, M&A, exits. Not just month-end reconciliations.
AI-native required. If you’re not already using AI daily, this isn’t your role.

Most CFOs we meet can build a model.

Very few can look at a model and tell you which business to acquire, which lever doubles margin, and which product line to kill. All before lunch.

That’s who we need.

Seventh Street Ventures is a venture studio based in Sydney.

We build and scale companies across SaaS, hospitality, childcare, and entertainment. Our flagship product is Desktop (thedesktop.com.au) — a compliance and policy management platform used by a massive share of the Australian childcare industry. It’s been operating for 15+ years. We are about to relaunch it. We’re treating it like a startup again. And we need a CFO who can run the numbers on what that means.

Desktop is the anchor. But you won’t sit in one business.

You’ll operate across 4+ active companies. Capital raises. M&A. Due diligence. Financial modelling that actually drives decisions, not slides that collect dust. You’ll work directly with the founders and CEOs. When an opportunity lands on the table, you’ll be the one who tells us whether to move or walk away. Fast.

What the job actually looks like

You own the financial models for every business in the portfolio. Not as a reporting exercise. As a control system.

Every week, you review the numbers across every company. You know the unit economics cold. You know which business is burning too fast, which one has margin hiding in the wrong cost line, and which opportunity every business has for EBIT expansion. You surface the five things the CEO of each business should be focused on this week, the actual pressure points, and you tell them directly.

You build the models that determine whether we raise, acquire, or exit. You run DD on targets in days, not months. You model Desktop’s growth trajectory: SaaS metrics, churn, LTV, expansion revenue, CAC payback. And you do the same across the portfolio.

When a CEO says “revenue is up,” you’re the one who says “yes, but gross margin dropped 4 points because of X, and if we don’t fix it by Q3, we lose the unit economics that make this business worth acquiring.” That level of detail. Every week. Across every business.

You don’t wait for someone to ask. You find it first.

You need to be AI-native. Not AI-curious. AI-native.

We don’t mean you’ve used ChatGPT to write an email. We mean you’ve rebuilt how you work. Your financial models get built faster because AI does the scaffolding. Assumptions get stress-tested in minutes, not days. When you’re in a data room during DD, AI is parsing documents alongside you. The boring stuff is automated so you can focus on the decisions that matter. If someone has to explain to you why AI matters for finance, you’re already behind.

This is non-negotiable. We will ask you how you use AI in your current workflow. We will want specifics. Tools, use cases, results. If you can’t answer that clearly, we’re not the right fit.

You’ll thrive here if you:

Have led capital raises, especially in tech or SaaS
Have done real M&A work, not just observed it
Understand SaaS metrics cold (ARR, NRR, CAC payback)
Have scaled a business through the messy early stage into something that runs properly
Can context-switch across multiple businesses without losing depth
Use AI tools daily for modelling, analysis, research, automation. Not because it’s trendy. Because it makes you faster and better.
Think like an operator, speak like an adviser, and back everything with data
Are obsessed with understanding what makes a business work and what’s going to break it

Not for you if:

You want one company, one set of books, and a predictable rhythm
You haven’t integrated AI into your finance work yet
You need someone to tell you what to prioritise
You’re more comfortable reporting on the past than modelling the future
You treat M&A and capital raises as someone else’s job
