Rex turns your business numbers into a story you actually understand — and flags the weird stuff before it becomes a real problem. He looks at MRR, burn, CAC, and churn so you always know exactly where you stand.

Full P&L breakdown from revenue, expense, and subscriber data: MRR, ARR, growth rate, gross margin, burn rate — with RED/AMBER/GREEN health flags.
Project any metric forward up to 365 days using historical data, with confidence bands and seasonality. Works on MRR, churn, CAC, or any time-series dataset.
Enter cash, burn, and revenue — get exact runway with growth scenarios. Or calculate CAC by channel, LTV, and payback period from your marketing spend and customer data.
Model what happens under different assumptions: cut burn by 20%, double down on a channel, raise a bridge. Compare scenarios side-by-side before making the call.
Auto-generate polished monthly investor updates from your live metrics. Or get a weekly digest: what moved, what's weird, and what to watch — delivered to your inbox.
Upload any CSV — Stripe export, ad spend report, bank statement — and Rex parses, stores, and adds it to your metrics dashboard instantly.
Rex is an AI financial analyst for SaaS founders who need to know their MRR, burn, CAC, and runway without staring at a dashboard every morning. He plugs into Stripe, your bank, and your ad platforms, tracks every SaaS metric that matters, and flags anomalies before they become bad news in a board deck. Think of him as an AI CFO-on-call: he doesn't close your books, but he'll tell you exactly where you stand, what changed, and what to pay attention to this week.
Stripe, bank accounts, ad platforms (Meta, Google), and your accounting tool if you have one. Rex reads the data and builds a baseline of your unit economics in hours, not weeks.
Tell Rex your KPIs — MRR growth, CAC, LTV, churn, burn rate, runway. He tracks them automatically and establishes normal ranges so anomalies stand out.
Daily or weekly briefings on your financial health — what's up, what's down, what's weird, and what you should look into. Investor-update emails on demand.
No more spreadsheet panic before a board meeting. Rex keeps a live read of your runway — number, not estimate — and tells you when it's slipping.
Not the back-of-napkin version. Rex breaks CAC by channel, tracks payback period, and flags when a channel's getting expensive before you've wasted another month's budget on it.
A 3x CAC spike on one ad set on a Tuesday afternoon. Churn concentrated in one cohort. Revenue recognized on a refunded charge. Rex flags these the day they happen.
Monthly investor updates with real metrics, narrative, and the three things you want investors to notice. You approve, you send.
Founders preparing for a fundraise or board meeting
Operators who need daily metric visibility without a CFO
