The Signal-Loss Problem

Your best signal never reaches the ad platform.

Meta and TikTok optimize on conversion data. ATT, ad blockers, and fragile SDK pipelines strip that data out before it reaches the model.

Paid conversions100

OutcomeAlgorithm optimizes blind. 0.42× ROAS.

01

You send budget

The platform starts searching for buyers.

02

Signal gets stripped

ATT, blockers, and SDK gaps remove purchase events.

03

The model learns wrong

Spend drifts toward cheap installs instead of valuable users.

04

ROAS bleeds

CPI looks healthy while revenue attribution collapses.

How AppCat Solves This

Route the click through a path the algorithm can see.

AppCat turns web-to-app traffic into a clean server-side conversion loop: click, landing page, store, install, match, CAPI.

Customer stories

Loved by builders who care about their data.

Founders, growth leads, and CTOs running real apps on AppCat.

★★★★★

"We swapped a $4k/mo MMP for AppCat in an afternoon. Match rate went up, our CFO is happier, and we actually understand our funnel now."

Rasha Madani

Head of Growth · PixMorph

★★★★★

"The deep-link routing alone paid for the year. Our cold-start install rate is up 22% since switching."

Jamie Cho

CEO · troolr

★★★★★

"Meta CPI dropped 43% the week we wired up CAPI. The algo finally had something to optimize against."

Maya Kapoor

Performance Lead · Lumen

★★★★★

"We were going to build this in-house. Six months saved, and AppCat ships features we wouldn't have thought of."

Devon Kapoor

CTO · Hyperdrive

★★★★★

"The dashboards just work. No more guessing which campaign is profitable. Our marketing team finally trusts the numbers."

Priya Desai

VP Marketing · Stride

★★★★★

"Three lines of SDK code, three minutes of setup. ROAS was up 2.4× two weeks later. My investors thought I faked the chart."

Alex Tanaka

Founder · Finch

★★★★★

"AppCat replaced AppsFlyer, Branch, and a custom warehouse pipeline. One bill, one dashboard, one source of truth."

Sara Nguyen

Head of Data · overlap.cc

★★★★★

"SOC 2 in-week sign-off was the unlock. Our security team usually kills tools like this. They actually liked it."

Marcus Bell

Eng Lead · Plotline

★★★★★

"The TikTok integration found us a new buying audience in week one. $0.62 CPI, never seen anything like it."

Lena Park

Growth Marketer · Hyperdrive

★★★★★

"Web-to-app campaigns are night and day. We get attribution back across the install boundary, which used to be a black hole."

Tomás Ríos

Performance Director · finch.app

★★★★★

"Their support is unhinged in a good way. Slack reply in 4 minutes, on a Sunday, with a working code patch."

Eli Frank

Mobile Eng · Linear

★★★★★

"Real-time event feed is genuinely magical. We caught a misconfigured pixel during a launch and saved the campaign."
