The Mobile App Agency That Scales User Acquisition Profitably
Scalebay is a mobile growth agency built around one number: your LTV. We run paid user acquisition and App Store Optimisation together, so every euro of spend is priced against what a user is actually worth — and your unit economics hold as you scale.
Most agencies optimise for installs. We optimise for profitability. As a user acquisition agency working across iOS and Android, we buy media on Meta, Google, TikTok and Apple Search Ads, optimise your App Store and Google Play listings, and model cohort retention and lifetime value net of VAT and store commission — so you know your true CAC, payback window and LTV:CAC ratio before you scale, not after. Since 2020 we've managed over €1M in quarterly ad spend across 70+ mobile apps, in subscription, gaming, fintech, health and media, for teams like Poulpéo, Euronews, Le Point, Django, Free2move and Equito.

FAQ — Frequently Asked Questions
What does Scalebay do as a mobile growth agency?
We're a mobile-first growth agency. We run paid user acquisition across the major app channels, optimise your App Store and Google Play presence (ASO), and model retention and LTV so every euro of spend is tied to real unit economics. What sets us apart: we focus on getting apps to the metrics that unlock the next funding round — and for a select few, we invest alongside you.
What kind of apps do you work with, and at what stage?
Mobile apps with a product people come back to — subscription, gaming, fintech, health and beyond — from early traction through scaling. The key is enough retention data to model LTV and a team ready to grow. If you're closer to launch, we help put the measurement foundations in place first.
Do you work on both iOS and Android, and internationally?
Yes — we run and model iOS and Android separately, because their retention and LTV behave very differently, then blend them by your real user split. We manage acquisition across geographies and tailor channel mix, creative and store presence to each market.
Which channels do you run user acquisition on?
Typically Meta, Google, TikTok, Apple Search Ads and select programmatic networks — but the mix follows your app and audience. We don't marry a channel; we put budget where payback is strongest and diversify as you scale so you're never dependent on a single source. See how we run user acquisition →
How does ASO fit with your paid user acquisition?
They compound each other: paid traffic lifts your store rankings, and a well-optimised store page converts more of every click you already pay for, lowering your effective CAC. We work keywords, screenshots, icon and store A/B tests alongside the media, on both the App Store and Google Play. See how we approach ASO →
How do you approach creative?
Creative is the biggest lever in modern UA, so we test constantly — producing and iterating concepts, angles and formats, scaling the winners and retiring fatigued ones. The goal is a steady pipeline of fresh creative feeding your best channels.
How do you handle iOS attribution and measurement after ATT?
We work within SKAN and the post-ATT world — but our real edge is proprietary: a measurement setup built around a mobile measurement partner (MMP) that keeps user-level data intact, so ATT doesn't leave us flying blind the way it does most teams. Paired with incrementality testing, that gives you attribution you can actually base budget decisions on — on infrastructure you own.
How do you use LTV and unit economics to drive growth?
LTV is the anchor for every decision. We build it from your real cohort retention — iOS and Android separately, net of VAT and store commission — then use it to set target CAC, bidding and payback windows. That's how we scale spend hard without breaking your economics — the same model behind our free LTV calculator. Try the free LTV calculator →
What results can we expect, and how fast can you scale?
Every app is different, so we start by agreeing the target CAC, ROAS and payback your economics support, then scale toward them. Early weeks focus on measurement and creative testing; from there we push volume as fast as payback allows. We stay transparent about what's working and what isn't — no vanity metrics. See our case studies →
How do you help apps get ready to raise a funding round?
Investors fund efficient, defensible growth. We help you hit the benchmarks they look for — healthy LTV:CAC, predictable payback, channel diversification — and turn your metrics into a growth story that reads as fundable. For us, growth and fundraising aren't separate workstreams: the first sets up the second.
Scalebay invests in apps — how does that work?
For a select number of the apps we grow, we don't just take a fee — we invest, so our upside is tied to yours. Structures depend on stage and fit (equity or hybrid arrangements). If you think there's a match, the best next step is a conversation about your app and goals.
What's the minimum budget, and how long is the commitment?
It depends on your stage and goals — we'll be straight with you about whether the timing is right rather than take on a fit that won't work. We keep commitments reasonable and prove value early; the fastest way to a clear answer is a quick call.
How do you price, and do we keep our ad accounts and data?
We tailor the model to the engagement — retainer, performance-linked, or, where we invest, a blend. And yes: you own your ad accounts, tracking, data and creative. We build on your assets, so nothing is held hostage if we ever part ways.
How do we get started?
It starts with a conversation about your app, your numbers and where you're headed — often a raise. From there we scope the fastest path to impact and what a first engagement looks like. Book a call from this page, or pressure-test your economics with our free LTV calculator first.
