James K.
SaaS Founder
“Been comparing Meta reporting to GA4 manually for two years. Decimly does it in 10 seconds and shows the exact gap. That gap was a lot bigger than I expected.”
Julia M.
Marketing Manager
“I was convinced one of our Google campaigns was performing. Decimly compared it against Analytics and the real conversion rate was half of what the platform was showing. We cut it the same day.”
Thomas R.
Founder
“Three months in, we've cut 4 campaigns based on the verdict. Ad spend is down 30%, revenue is exactly the same. The data was always there — we just couldn't see it clearly.”
Nathan B.
E-commerce Manager
“honestly expected another analytics dashboard. what i got was something that tells me what to do, not just what's happening. flagged a campaign as Cut that i'd been running on autopilot for months. numbers backed it up.”
Sarah L.
Performance Marketer
“Managing Google, Meta, and TikTok at the same time is a mess. Decimly normalizes everything into one view. No more guessing which platform numbers to actually trust.”
Alex P.
Agency Owner
“We run campaigns for 15+ clients. Cross-platform reporting used to take a full day per client. Now I pull one view, get a verdict, and the client trusts it — because the numbers don't come from a single biased platform.”
Priya V.
Growth Lead
“ROAS was dropping and i couldn't tell if it was the audience, the offer, or CPM. Decimly broke it down — turned out CPM had spiked 3x on one specific placement. Fixed it in an hour. Would've taken me a week otherwise.”
Marc D.
Media Buyer
“It told me to cut a campaign I'd been running for 3 months. I ignored it for a week. Then I cut it. Margin went up 14%. Should've listened the first time.”
Carlos M.
Digital Strategist
“Clean interface, and the verdict system is what other tools have been missing. Every tool gives you more data. Decimly gives you less — and the less is exactly what you need to make a call.”
Emma T.
Head of Acquisition
“The 'Cut it' badge on a campaign we were about to scale saved us from putting more budget into a losing setup. AI flagged an audience-offer mismatch we'd completely missed.”

Frequently asked questions
Everything you need to know about Decimly.
Is Decimly for me if I spend $1k–$10k/month on ads?+
Yes — that's exactly who it's built for. Decimly becomes valuable from your first $1k/month. You're spending real money and you deserve a clear answer on what's working. No enterprise complexity, no data team required.
What's the difference between Decimly and GA4?+
GA4 shows you data. Decimly tells you what to DO with it. GA4 gives you sessions, bounce rates, events. Decimly takes that data + your ad spend, analyzes every campaign, and gives you a verdict: keep it, cut it, or scale it. They're not the same tool.
How long does setup take?+
Under 2 minutes. Connect Google Ads + Google Analytics via OAuth (one click each), pick your first campaign, and get your first verdict. No configuration, no dashboard to build, no data team needed.
Do I need to be technical to use it?+
Not at all. If you know what ROAS means and you run paid ads, you can use Decimly. There's no SQL, no custom dashboards, no setup. You connect your accounts, pick a campaign, and Decimly does the rest.
Decimly is not a replacement for GA4, so what exactly is it?+
Decimly is your marketing decision layer. GA4, Google Ads, Meta — these are your data sources. Decimly sits on top of them, centralizes the information that matters, and tells you what action to take on each campaign. It's the step between data and decision.
Does Decimly touch my ads, my budget, or my campaigns?+
Never. Decimly is strictly read-only. We connect via Google OAuth and can only read your data to analyze it. We cannot create, modify, pause, or delete any campaign. Your accounts are 100% safe. You can revoke access anytime in your Google settings.
Is my data safe? Who can see it?+
Your data is encrypted and stored securely. We never see your Google password — authentication goes through Google's OAuth. We don't sell your data or share it with third parties. You can delete your account and all your data at any time, no questions asked.
Does it work with Meta Ads, TikTok, or LinkedIn?+
Google Ads and Google Analytics are fully integrated with auto-sync. For Meta, TikTok, LinkedIn and others, you can manually enter your campaign data today. Direct integrations for these platforms are coming soon — sign up to be notified.
How does AI work in Decimly?+
Decimly's AI never runs in the background. You trigger it when you're ready — click 'Analyze' and it reads your real campaign data, compares what the platform reports versus what actually happened on your site, and explains why a campaign performed the way it did. It doesn't give generic advice. It gives you a root-cause diagnosis — audience, creative, bid, or tracking — based on your actual numbers, with one actionable fix.
