Surviving the First 90 Days as an Integrator in a New Business

by Adam Harris | Oct 1, 2025 | Blog

Stepping into the Integrator seat isn’t like starting any other leadership role. You’re not walking into a steady ship with a neat handover folder, you’re climbing into the cockpit of a jet that’s already in the air, with a Visionary who’s brilliant at ideas but often frustrated with execution.

The business is moving fast. People are looking at you for answers. The Visionary wants traction yesterday. And you’ve got 90 days to prove that you’re the right person to bring order, focus & accountability.

Sound intense? That’s because it is. The first 90 days will define whether you’re seen as a true Integrator, the one who makes the vision happen, or just another manager who couldn’t keep up.

Here’s what it takes not just to survive, but to set yourself up for long-term success.

Day 1–30: Listen, Learn & Build Trust

Your first month is about trust-building, not empire-building. Many Integrators make the mistake of trying to “fix everything” straight away. But in an entrepreneurial business, credibility comes before change.

Listen more than you talk. Have one-on-one conversations with every member of the leadership team. Ask open questions: What’s working? What’s broken? Where do you feel stuck?
Study the Visionary. Notice how they think, how they communicate, and where they get pulled into weeds. Your role isn’t to copy them, it’s to complement them.
Map the Accountability Chart. Even if it’s messy, sketch out the seats. Who’s actually responsible for what? Clarity is the first step to accountability.
Spot the culture cues. Is this a team that avoids conflict? Do they struggle with follow-through? Understanding the dynamics helps you know where to start.

Quick win: Follow through on every small promise in those first 30 days. If you say you’ll get something done, do it. This is how you start building trust, one commitment at a time.

Day 31–60: Introduce Discipline Gently

Once you’ve established trust, it’s time to bring in the EOS tools that create discipline, but carefully. Too much change at once, and the team will push back.

Level 10 Meetings™. Start with the leadership team. Keep them short, sharp & consistent. Early on, the goal isn’t perfection, it’s rhythm.
Rocks. Narrow the company’s focus to 3–7 truly strategic priorities. Most entrepreneurial teams try to do 50 things at once and end up frustrated. Rocks create laser-sharp focus.
Issues Solving Track™. Teach the team how to Identify, Discuss & Solve issues instead of endlessly circling them. Nothing builds confidence like solving problems that have lingered for months.
Scorecard basics. Introduce a handful of weekly measurables. Don’t overwhelm the team, show them that data brings clarity, not complexity.

Quick win: Pick one or two burning issues and solve them using IDS. When the team sees an old problem finally resolved, they’ll buy into the process.

Day 61–90: Deliver Quick Wins & Reinforce Accountability

Now comes the make-or-break phase. By this point, people are watching to see if you’re just a process junkie, or if you can actually deliver results.

Highlight measurable progress. Show the Rocks completed, the Issues solved, and the improved meeting scores. Put results on the table.
Hold people accountable. This is where you’ll have tough conversations. If someone’s not getting it, not wanting it, or not having the capacity (GWC™), call it out. With kindness & firmness.
Tighten your partnership with the Visionary. Have a weekly check-in. Align on priorities. Present a united front to the team. When the Visionary backs you, everyone else will too.
Show balance. Don’t just enforce process, demonstrate empathy. Remind the team EOS isn’t about bureaucracy; it’s about making their lives easier.

Quick win: Share a “before and after” comparison, e.g. meeting length cut from 2 hours to 90 minutes, or decisions made in 10 minutes instead of 3 weeks. Nothing sells EOS like proof.

Beyond 90 Days: From Survival to Success

If you’ve made it this far, you’re no longer “the new Integrator.” You’re the person holding the business together, creating traction, and giving the Visionary space to lead. But the work doesn’t stop, it shifts.

Strengthen the V/I dynamic. Protect your relationship with the Visionary. EOS only works when Visionary & Integrator are aligned.
Stay consistent with EOS tools. Level 10s, Rocks, Scorecards, IDS, these are your guardrails. Don’t let them slide, even when things are going well.
Embed accountability. Over time, the leadership team should rely less on you chasing them, and more on their own commitment to the process.
Think succession. Great Integrators don’t just run the business, they build leadership capacity for the next stage of growth.

💡Remember: surviving the first 90 days is about proving you belong. Thriving beyond 90 days is about multiplying your impact across the whole business.
