Merging teams in 2025 isn’t just about streamlining org charts and hoping everyone magically gets along. It’s about aligning cultures, calming chaos, and making sure your carefully nurtured team dynamics don’t go down the drain.
And if you're an HR leader, People & Culture manager, or office admin tasked with leading the charge… whew, we see you.
The pressure is real. Executives want ROI. Employees want clarity. You just want a smooth transition without 700 Slack messages that all say, “Do we report to the same manager now?”
This guide is here to help.
Bringing two teams together can spark growth and collaboration. But without the right approach, you’ll likely run into:
Here’s the good news: You can absolutely make this work. It just takes intention, structure, and a few creative tools (spoiler: we’ll even show you how AI can help).
Q: What’s the #1 reason team mergers fail?
A: Lack of clear communication.
Make sure your people hear the why before they fill in the blanks with fear.
Action Tips:
Pro Tip: Don’t just talk at your team. Create two way dialogue. Use live polls, suggestion boxes, and one on ones to start conversations.
When teams don’t know what they’re working toward together, silos pop up fast.
Here’s how to avoid that:

Your teams may come from departments with very different vibes. One’s a Slack loving startup crew, the other thrives in Outlook calendars and formal decks.
This isn’t about choosing one over the other. It’s about honoring both, then building something new together.

Now for something a little off the wall… AI isn’t just for crunching numbers or summarizing meeting notes anymore.
Here’s how AI can actually help merge your teams:
Use ChatGPT to generate unique icebreaker questions that go beyond “What’s your favorite movie?” Think team based trivia, values alignment games, or light challenges like “Design a new team mascot in 60 seconds.”
Try AI driven sentiment analysis tools (like CultureAmp or Lattice) to track how your team is feeling week by week. These tools can summarize feedback into trends so you can respond before issues escalate.
Use generative AI to map overlapping responsibilities between the two teams and suggest updated org structures or responsibilities. (Just don’t skip the human review!)
Run an AI analyzed workplace personality quiz (e.g., Crystal or Humantic AI) to see where collaboration might flourish or clash. Use those insights to pair project teams more intentionally.
The most successful mergers feel like a new beginning, not the absorption of one team by another.
Q: How can you help your new team feel like one group?
A: Create shared experiences that bond people emotionally, not just organizationally.
One of our favorite ways? The AppMazing Race.
It’s equal parts cerebral, tactile, and ridiculously fun. Teams travel from checkpoint to checkpoint (using our proprietary app technology) solving road block challenges that require communication, trust, and real collaboration.
You’ll go from “us vs. them” to “let’s beat this next challenge together.”

Or, if your teams thrive on strategy? Opt for the AppMazing Hunt, where each group builds their own adventure by choosing from high-point challenges and collecting “loot.” It’s teamwork meets gamification in the best way.
If you’re reading this, you’re probably the one holding this whole merger together. You’re managing expectations from the top while trying to protect culture at the grassroots level.
