You don't have a measurement problem. You have a decision problem.

Your CEO wants a number. The board wants a plan. Friday you have 90 minutes to decide where €50K goes next week.

Your attribution platform says one thing. Meta says another. The MMM file from your analyst is a month old. The Sheet you built yourself doesn't tie out either.

So you ship "same as last month" — because you have no defensible reason to change it. The growth ceiling gets closer.

Cassandra exists to give you the one sentence you can repeat to your CEO: where the next euro goes, what it returns, and how we know.

For every team that measures success in revenue, customers, donations, enrolments, or accounts.

How Cassandra gets you to your number.

Three decisions, in order, every quarter.

1. Forecast — see if your plan hits the goal, before you spend a euro.

Drop in your current media plan: how much revenue does it return this year? Is it on track for the target — or short, and by how much? Run an optimised version side-by-side: same budget, different mix. See the revenue gap between "what you'd ship today" and "what gets you there." Pick the plan that lands the number. No guesswork. No "let's see what happens." You commit a plan you've already seen the answer to.

2. Stress-test — find the risky assumptions before they blow up the forecast.

Every plan rests on 2-3 assumptions that, if wrong, miss the number. Is podcast really driving revenue, or halo from Meta? Will TikTok scale to €200K/mo or saturate at €80K? Is your TV efficiency stable in Q4 promo season? Cassandra surfaces the assumptions that move the forecast the most — and runs the test that resolves them in 4 weeks. So you know your plan is real before you commit the budget.

3. Track — when reality drifts, get the budget change that gets you back on target.

Every week, Cassandra compares actual revenue to the forecast. If you're behind, the tool tells you the exact budget change to implement this week to recover — quantified, defensible, in your CEO's language. Not a chart. A decision. When the plan still works, you ship "stay the course." When it doesn't, you ship the adjustment. Either way, you have an answer for the Monday meeting.

From data to decision, on autopilot.

Four steps. You connect once, we run the loop every day.

Step 1

Auto-connect your data.

Plug Cassandra into Meta, Google, TikTok, your shop, your CRM, your podcast spend, your TV invoices — once. Every euro of spend and every euro of revenue lands automatically.

Step 2

Auto-measure with two methods.

Incrementality measurement and marketing-mix modelling at the same time — two independent reads on every channel, every week. When they agree, you trust. When they disagree, you know where to test.

Step 3

Plan the year. Simulate before you spend.

Drop your plan in. Get a forecast vs target. Run optimised variants side-by-side. Pick the plan that lands the number — before you spend a euro.

Step 4

Track every day. Adjust when reality drifts.

Cassandra refreshes the data every day and compares actual revenue to the forecast. Behind plan? You get the exact budget change to implement this week to recover.

Powered by incrementality measurements and attribution — so every decision protects your cashflow from a budget call gone wrong.

End the Monday debate.

Meta says ROAS 4.2x. Northbeam says 2.1x. Your Sheet says 3.5x. Today, the loudest voice in the room wins — and the budget follows the voice, not the truth.

Cassandra puts every number on the same screen, in the same units. When they agree, you ship the decision. When they disagree, we name the gap and run the test that resolves it.

One source of truth. One sentence to your CEO. One budget you can defend.

"The team that aligned on one number last quarter shifted €280K — and grew revenue 11% the next."

From marketers who hit their number with us.

Eszter @ Cura of Sweden

"We shifted budget toward what was actually working — and watched it work."

Mike Taylor @ AskRally

"A second brain immune to internal politics."

Cristian @ t2ó

"We picked the channel to scale, simulated the future, and stopped running the budget on last-click."

Giovanni @ Velasca

"We redefined every partner's role in the mix — with confidence, on our own."

Brady @ charity:water

"We can finally show how brand investment pays off — to the board, on a slide."

Giancarlo @ Boscolo Viaggi

"Our customers' journey isn't last-click. Our measurement isn't either."

We optimise for the truth that hits your number.

The advertising industry rewards platforms that flatter themselves. Every tool tells you it drove the sale. Add them up — you get 150% of your revenue. The marketer in the middle gets blamed when the number doesn't land.

Cassandra was built for the marketer with a target on her head. Even when the truth is uncomfortable. Even when the answer is "your last campaign was theatre — kill it." Even when the recommendation is "pull all your budget from a channel a vendor is paid to defend."

If we optimised for what flatters us, we wouldn't be useful to you. So we don't.
