The part most founders wing.

You’re exceptional at product. At brand. At knowing your customer before they know themselves. But the numbers? Cash position, margin by SKU, where the marketing budget is actually working — that’s the part running quietly in the background, half-understood and mostly hoped for.

Sentinel changes that. Not with more data to drown in. With one clear read, every week, and the actions already drafted.

What Sentinel reads

Three pillars. One read.

Cash

Know your runway before it matters.

Your buffer, updated daily. Sentinel tells you how many days you have, what’s coming, and when to act — before the moment arrives.

Inventory

Buy the right stock. Every time.

Sentinel sizes every PO to your cash position and forecast demand, then drafts the order and sends it to your supplier.

Marketing

Spend where it works.

Every channel, measured by real return. Sentinel tells you where the next dollar should go — then places the buy across Meta, Google, and TikTok.

Belief

Numbers build nerve.

Signal

One read.
Every Monday.

One number. One sentence. One nudge.

Cash, weekly

Understand your shop.
Then act on it.

The financial team you always needed.
Without the cost.

A fractional CFO. A marketing analyst. A supply chain manager. The founders who have all three move faster, waste less, and sleep better.

Sentinel does the work of all three — for $1,000 a month, live in 24 hours.
