## Overview
Cash on hand, monthly burn, runway in months — plus what-if scenarios for any hire, spend, cut, or capital injection. Reads your unified ledger. The number every founder should know before every spend decision.
## Capabilities
1. **Real cash on hand** — Sums every account balance — bank, Airwallex, Stripe pending payout, Wise — into one number. Not yesterday's number — today's.
2. **Trailing burn rate** — Net burn over the last 1 / 3 / 6 months. Three numbers because one is volatile; the trend matters.
3. **Runway in months** — Cash ÷ burn = months. Computed against each trailing window so you see best/worst case.
4. **Scenario modelling** — What if I add $4k/mo contractor? Cut $2k/mo of SaaS? Land a $10k one-time invoice? Each scenario re-runs the runway number instantly.
5. **Alert thresholds** — Set a warn-at threshold (e.g. <6 months) and a panic-at threshold (e.g. <3 months). Skill flags loudly when you cross.
## Pipeline
## Use Cases
- **Before a hire:** Considering a $4k/mo contractor? Model it. See whether you stay above your warn threshold for the next 6 months. Make the call with a number, not a vibe.
- **Monthly cash check:** Run on the 1st. Get cash · burn · runway in one report. Commit. The repo becomes a history of your cash position.
- **Pricing / spend cut decisions:** Considering killing a marketing channel that costs $2k/mo? Scenario it. See the runway delta. Sometimes the answer is 'keep it' because cutting buys less time than expected.
