Short answer: a mobile growth team covers three jobs: getting measurement right, making and testing creative, and buying media against the numbers. Hire one strong growth lead first, someone who can own the numbers and run the first channel. Then add creative capacity before anything else, because creative is the main lever and often the first bottleneck. Buy what you can’t keep busy full time, from freelancers or an agency, and bring roles in-house when there is enough steady work to fill them.

What does a mobile growth team actually do?
Three jobs, whoever does them:
- Measurement. Mobile is idiosyncratic: SKAdNetwork and AdAttributionKit on iOS, your mobile measurement partner set-up, which in-app events map to revenue, and reconciling what each platform claims. Get it wrong and every later decision rests on bad data. What a mobile measurement audit looks like is a good starting checklist.
- Creative. Platforms automate many targeting and bidding decisions. We therefore make creative the main area of work, while checking measurement, the offer and the product too. Someone has to decide what to make, get it made, test it and learn from it, every week.
- Media buying and the money. Setting up campaigns, feeding each one enough conversions a day, scaling what works and judging everything on cost per conversion and payback. User acquisition is a financial function as much as a marketing one.
Who should be the first hire?
A growth lead who can run the numbers and the first channel themselves. For most apps that first channel is Meta (plus Apple Ads (formerly Apple Search Ads) for subscription apps, or Google App campaigns on Android for games), and one good person can run it end to end at the start.
What to look for:
- They have run paid acquisition themselves, with real budget, and can explain how they decided to raise or cut spend on a campaign.
- They think in unit economics: cost per conversion, payback, what a user is worth.
- They care about creative, not just bids and budgets. Ask them to critique your current best ads against what else runs in your category.
I would use a paid trial project alongside interviews. Give them a defined problem, an agreed spending limit and appropriate access, then assess their reasoning as well as the result.
My hiring preference is demonstrated operating skill over category tenure alone. A strong subscription marketer may be able to learn a game’s economics, but test that understanding instead of assuming it transfers. Category knowledge matters more when monetization, regulation or the product is unusual.
What should you add as spend grows?
Add capacity where the bottleneck is, usually in this order:
- Creative strategy and production. Once the first channel works, check whether making and testing enough good ads is the constraint. A creative strategist decides what to make; production (designers, editors, UGC creators, AI tools) makes it. Within each creative direction you want several ads across different angles, hooks and formats. See what a creative strategist does.
- More channels, and someone to run them. Our planning guide is to test Google on iOS and TikTok from about $50K a month, with $5K to $10K for each test; ad networks come in around $200K a month and programmatic from about $250K. Each new channel needs someone with the time to feed it properly. How to pick ad channels for a subscription app has the order.
- Analytics. When decisions start to depend on cohort and payback analysis across channels, someone needs to own the data full time rather than fitting it around buying.
Hire when work is waiting, not when the calendar says so. A sign you’re late: good ideas sit untested for weeks because nobody has time to make or launch them.
Is it better to hire a growth team or use an agency?
It depends on your spend, how much creative you need and how fast you need to ramp. Based on your needs, you can keep media buying in-house and buy creative strategy and production, or keep the product in-house and buy user acquisition plus creative strategy and production. Freelancers fit well-defined pieces of work. In-house versus agency versus freelancer compares cost, ramp time, creative volume and risk.
Whatever you buy, keep two things inside the company: someone who owns the numbers and the decisions, and access to your own ad accounts and data. An agency should give you direct access to the people doing the work and the reasoning behind each decision.
For context, RocketShip HQ founder Shamanth Rao grew an app from $0 to $1.5M a month in ad spend in 11 months while in-house. That experience informs our emphasis on creative strategy and production.
How much technical skill do you need in-house to run a creative testing set-up?
Less engineering than you might think, more judgment. Someone needs to understand how your ad accounts are structured, how tests are read, and how your measurement partner reports results, so that a winning ad is a real winner and not a reporting artefact. Building the tooling around creative (templates, AI production pipelines, reporting) is increasingly part of creative work itself, so either hire people who are comfortable with it or work with a partner who already has it.
Frequently asked questions
What roles does a mobile growth team need? A growth lead who owns the numbers and media buying, creative strategy and production, and, as spend grows, more channel owners and a dedicated analyst. Early on, one person may cover several of these.
Should I hire a dedicated growth marketer? Assign one person to own the numbers and the first channel. Make it a full-time hire when the workload and economics justify it; a founder or fractional lead can cover the role earlier.
Is it better to hire a growth team or use an agency? It depends on spend, creative needs and ramp speed. Many apps keep one function in-house (media buying or product) and buy the rest, then bring roles in-house as there is enough steady work.
When should a mobile app add a creative strategist? When deciding what to make and testing it has become a sustained bottleneck. The work can start with a fractional strategist or an agency before it supports a full-time hire.
