100% Free Ad Testing Engine
Your Ad Account Is Bleeding Money.
And You Can Feel It.
You wake up. You check your phone. The numbers dictate your mood for the rest of the day.
Sound familiar? You’re not alone. It’s a pattern we see inside 20 to 40 ad accounts every single week. Founders running Meta ads at $3K, $5K, $10K+ a day, and most of them are making the same costly mistakes.
The Slow Chew
Too many ads getting $40 each in spend over 20 days. No learnings. No winners. Just budget quietly disappearing.
No Kill Rules
You don’t know the exact dollar amount where you should cut an ad. So losers run for days, or weeks, too long.
Wrong Budget Split
How much goes to scaling winners vs. testing new creative? Most founders guess. The wrong split costs you thousands every month.
Flying Blind
You can’t answer the one question that actually matters: “What do we do next, and why?” So you second-guess every move.
“I hate how much my mood relies on ad performance. Ads doing well; great mood. Ads underperforming even just one day; I’m an anxious mess.”
The problem isn’t your product. It’s not even your creative. It’s that you don’t have a system telling you exactly how much to spend per ad, exactly when to kill it, and exactly when to scale.
That’s what this tool does.
Plug In 5 Numbers.
Get Your Entire Testing System.
The Ad Testing Engine takes your current daily budget, target CPA, CPM, and ad performance data, and calculates a complete testing plan in seconds.
Account Health Diagnosis
Enter your current winning, testing, and losing ad counts. The engine instantly tells you if your account is strong, stable, thin, or critical, and what to do about it.
Exact Budget Allocation
See the precise dollar split between scaling winners, testing new creative, and exploring new angles. The 70/30 rule (or 90/10, or 100/0 depending on your account state), calculated automatically.
Spend-Per-Test + Kill Rules
Know the exact dollar amount to spend on each ad test before you decide to kill it or scale it. Includes conservative kill thresholds at 1x, 1.5x, and 2x your target CPA with minimum conversion counts required before you scale.
Creative Pipeline Calculator
How many concepts per month? How many ad variations? How many new winners can you expect? The engine maps out your entire creative production schedule based on your real numbers.
Scale Scenarios + Downside Planning
See what happens to your testing capacity at 1.5x, 2x, 3x, and 5x your current budget. Plus a worst-case scenario showing exactly when to hit the brakes if nothing converts.
Diagnostic Playbook
When something breaks, the playbook tells you where to look inside Meta Ads Manager, what to check, and how to fix it. Four pillars: Hook, & Landing Page, Offer, and Audience, diagnosed in order.
Without a System vs. With One
| The Decision | Without This Tool | With This Tool |
|---|---|---|
| How much to spend per test | “I’ll just give it a few days” | $90 per test (2× your $45 CPA) |
| When to kill an underperformer | “Maybe it’ll pick up…” | Kill at $45 spend with 0 conversions |
| How much goes to testing | “I dunno, some of it?” | 30% testing / 70% scaling winners |
| How many creatives per month | “As many as we can?” | 12 concepts, 24 variations, ~4 winners |
| When to pause everything | “When I run out of money” | 5 test kills in a row → audit strategy |
Table values are illustrative based on example inputs. Your numbers will be calculated based on your actual account data.

Get My Free Ad Testing Engine →Built on the Framework Behind $200M+ in Managed Ad Spend
This tool is built on the operating system developed by Nick Shackelford and his team at Foundr Operators. Nick has personally managed or overseen ad spend for 127+ DTC brands…from Dollar Shave Club to Posh Peanut to Vessi Footwear. He’s a partner at BRÉZ, which surpassed $75M in revenue in three years.
This isn’t theory from someone who “used to” run ads. It’s the live operating framework behind real ad accounts spending real dollars right now.
The Bigger Picture
This Tool Is One Piece of the Full Operator System
The Ad Testing Engine gives you the numbers…how much to spend, where to allocate, when to kill, when to scale. That’s the starting point.
But knowing the numbers is different from having someone review your actual account, diagnose what’s really broken, and tell you the specific next move. That’s what Foundr Operators Membership is built for.
Inside Foundr Operators, you get weekly live coaching, bi-weekly 1-on-1 pulse checks with Nick’s team, a diagnostic operating system that covers traffic, creative, conversion, and economics, and a community of operators who are actively scaling and sharing what’s working right now.
Use the free tool. Run your numbers. And if you want the team behind the system reviewing your account and telling you exactly what to fix next – the membership is there when you’re ready.
Before You Claim Your Tool
What exactly do I get when I sign up?
Instant access to the Ad Testing Engine, an interactive tool that calculates your budget allocation, spend-per-test, kill rules, creative pipeline, scale scenarios, downside planning, and a full diagnostic playbook. You plug in your numbers, and it does the math.
Is this really free? What’s the catch?
It’s free. No credit card. No hidden trial. We built this tool because it demonstrates a small piece of the Foundr Operators system. If it helps you, great. If you want the full system with live coaching, 1-on-1 support, and a diagnostic operating system installed in your business, that’s the Foundr Operators Membership. No pressure either way.
Who is this for?
Ecommerce founders running Meta ads (or about to start). It’s especially useful if you’re spending $100+/day and don’t have a structured system for deciding how much goes to testing vs. scaling, how much to spend before killing an ad, or how many creatives you need each month.
I have an agency running my ads. Is this still useful?
Especially useful. If you’re paying an agency and getting reports you don’t fully understand, this tool gives you the framework to evaluate whether they’re allocating your budget correctly, testing enough, and killing losers fast enough. You’ll know what “good” looks like.
Every Day Without a System,
