Working with in-house teams: what they actually need from you
Say you’re a brand designer brought in by a VP of marketing. The person who hired you sits one floor up. Meanwhile, the two designers who own the brand guidelines sit next to you, and neither of them chose you. Working with in-house teams means doing good work for both, and this guide is about the second relationship.
It’s a common setup. In a 2023 ANA study with 162 respondents, 82% of members said they have their own in-house team doing work they’d otherwise hire an outside agency for. Of the respondents, 92% also work with external agencies, and those companies do an average 61% of all their work in-house.
That figure is the share of work respondents said their in-house team handles, not a share of budget. ANA’s release doesn’t describe the 162 respondents by size or sector, and the study measured outside agencies, not individual creators.
Methodology: the Association of National Advertisers surveyed its members in February and March 2023. ANA counts even a single person doing that work as an in-house team.
Our read: at a company with its own in-house team, you’ll likely be the outside person next to a team that does most of the work. That team is the part of the client that stays after you leave. Treat them as the owner of the work, and you arrive as relief rather than as a rival. (For the budget side, see where large marketers moved their money this year.)
Why you’re there, and why that matters to them
ANA’s respondents in that 2023 study also said work goes outside mainly for capacity, because the in-house team is too busy, or for capabilities they don’t have internally. That finding is about agencies. We’d read it as the likely reason you’re in the room too: extra hands or a missing skill, not a verdict on the team.
Still, the people beside you may have reason to worry. ANA wrote in a July 2026 article that in 2025, high-profile in-house teams across multiple industries were downsized, lost scope to external agencies, or shut down. It gave no counts or names.
One caveat covers all the organizational research in this guide: none of it studied creators working beside client staff. It covers temporary workers, student teams and workplace groups generally, so how it applies to you is our reading.
With that said, older research on temporary workers points the same way. A 2005 Journal of Applied Psychology study covered 149 full-time employees who worked with temporaries. Those with lower job security were more likely to see the temps as a threat. We’d read that as a sign that a colleague’s wariness may say more about their own position than about you.
You can’t fix their job security, but you can tell them early that you’re there to take load off, for a set scope and end date.
Working with in-house teams starts before the work does
You can settle most of the friction in this guide at your first meeting. Ask these five questions there, the first four with your hiring contact and the in-house lead both in the room:
- What do I need access to, at what level, and who approves it? Afterward, send one written access list so nothing waits on a login.
- Whose notes are input, and who has the final say? Then name that person in a short recap email after the meeting, so it’s on record.
- Who presents the work to leadership, and can I show it in my portfolio? Offer to let the in-house lead present it, and get the portfolio answer in writing.
- When does my part end, and who inherits the work? Knowing that tells you who to build for and whose tools to use.
- Why was I brought in, and what was the team told? Ask your hiring contact this one privately. If the answer is “nothing,” offer to explain your scope and end date to the team yourself.
Get access to their tools, not yours
Say you’re a developer building a landing page the in-house marketer will update every week. Build it in your own environment and they inherit a handover problem, but build it in their CMS from the first commit and they already own it. That’s the simplest rule for working with in-house teams: their tools, their files, their names for things.
Ask for the access the task needs, and no more. NIST calls this least privilege: restricting access to the minimum necessary to accomplish assigned tasks. It’s a security principle, not a legal rule. Still, a scoped request is easier to approve, and it shows you aren’t reaching past your brief.
On the access list, name each tool, the level you need (view, comment or edit) and who approves it, then keep the list, because it becomes your offboarding checklist. You might say: “Before we start, here’s what I’ll need access to. Who’s the right person to approve it?”
Settle credit before there’s anything to argue over
Credit gets tangled even among peers. University of Chicago researchers asked MBA students for their share of their study group’s work. On some eight-person teams, the totals exceeded 140%.
Their 2016 paper found that claims of responsibility routinely sum to more than 100%. Estimating others’ contributions first reduced the overclaiming.
There’s a second trap. In a 2003 Management Science paper built on two case studies and a manager survey, Menon and Pfeffer found that managers often value outsiders’ knowledge more than insiders’. Part of the reason is status: learning from an internal peer carries a cost. We’d read that as a warning: when the VP loves your idea, part of the credit may belong to someone who said it first.
So credit needs two separate agreements.
Internal credit. Let the in-house lead present the work to their leadership. Their standing outlasts your contract, and a lead who looks good to their boss is in a position to ask for you again.
Say out loud where ideas came from: “This builds on the layout your team explored last quarter. Would you like to walk leadership through it? I’ll take questions on the build.”
External credit. Agree portfolio rights in writing at that first meeting: whether you can show the work, name the client, and from when.
Find out whose judgment wins
When you’re working with in-house teams, your hiring contact and your reviewer can be different people who want different things. If they are, ask one more question before the first review: how do disagreements between them get settled? You’re looking for one decision-maker, the same principle we give clients in our guide to giving feedback on creative work. Even when the in-house lead isn’t that person, they live with the result, so give their notes a real hearing.
How to disagree with an in-house lead
An in-house lead is a peer who knows the brand’s history better than you and will still be there next year. That changes how disagreement works when you’re working with in-house teams.
A 2012 meta-analysis of 116 studies by de Wit, Greer and Jehn, published in the Journal of Applied Psychology, found stable negative links between relationship and process conflict and group outcomes. Task conflict, meaning disagreement about the work itself, showed no strong negative link with group performance. That doesn’t mean arguing about the work helps. Instead, we’d read it as a reason to keep the disagreement on the work, away from the person and from who owns the process.
In practice:
- Raise it privately first. A stakeholder review is the wrong place to disagree for the first time.
- Argue from their standards. Point to their brand rules, stated goal or audience data, not your taste.
- Show both versions. Put theirs and yours next to each other.
- If you’re overruled, log it and ship. Note the decision, then do their version well.
- Don’t go around them. If a real risk forces escalation, such as an accessibility failure or a broken launch, tell the lead first.
For the first step, try: “Can I show you something before the review? I think this version serves the goal you set. I’d like your read before anyone else sees it.” Our guide to getting client buy-in covers the persuasion itself.
Leave work they can keep
Working with in-house teams means building for the day you’re gone. Write decisions down where they’ll look. Keep editable source files in their tools, named so someone else can find them. Teach as you go: narrate a technique on a call, or leave notes in the file.

The team that stays
Your hiring contact judges what you delivered. The in-house team judges what they can do with it once your access ends. They decide whether you were relief or a rival, and they make that call after you’ve left.
