Study after study puts the failure rate of acquisitions somewhere between 70% and 90%. Ask the people who run integrations why, and the answer is rarely the strategy or the price. It is the people, and specifically the people who leave.
Less understood is which people matter most. Retention plans focus on the names at the top of the org chart, but much of a company’s value runs through a small group that no deal model, org chart or pulse survey can see: its SuperConnectors.
The blind spot in the deal model
A deal model counts what is formally visible: titles, headcount, rare skills and reporting lines. What it misses is informal influence, the trust, introductions and knowing who to ask that make the formal structure work. That informal layer is a company’s relational infrastructure.
The rest of the integration toolkit shares the blind spot. Due diligence examines contracts, financials and the leadership team, not how people are connected. The org chart shows who reports to whom, not who people actually go to. The 100-day plan runs on a project timeline, while large deals take 24 to 36 months to capture most of their synergies. Pulse surveys show how people feel, not who is holding everyone together.
Klint C. Kendrick, a Fortune 50 HR M&A executive in our network, describes watching an acquirer lose the people it was spending most to retain. Leadership identified the critical talent, offered them jobs and assumed the problem was solved. Nobody had understood the relationships holding the organisation together. Engineers walked out, and customers followed them to competitors.
This is why retention bonuses and earn-outs aimed at formal titles so often fail to stop the leak: they miss the informal leaders who carry the network.
What a SuperConnector is
SuperConnectors link colleagues, ideas, projects and resources across departments. They are the ones others go to for an introduction, a straight answer or help getting something unstuck, and that is what drives cross-team collaboration and innovation. Research suggests only 3- 5% of employees play this role.
They can sit at any level, including the leadership team, but many hold no formal authority at all. One SuperConnector, Alice, describes herself as being at the very bottom of the food chain, not a leader, not an executive, and suspects that is exactly why people come to her.
What defines them is not how many people they know, but how much those people trust them. SuperConnectors are sense-makers. When a deal is announced, people do not believe the slide deck; they ask the colleague they have worked with for years what it really means. That gives a SuperConnector a weight no integration plan or town hall can match.
Why a merger puts them under pressure
Trust makes SuperConnectors an integration’s biggest lever, and, left unsupported, its biggest risk. Once a deal is announced, they go from bridging one network to bridging two. Colleagues on both sides come to them for the real story, yet they have no mandate, no recognition and often no more information than anyone else.
That load has a cost. Research from ESMT Berlin, published in Organization Science, found that bridging disconnected groups leads to stress, then burnout, then friction with colleagues, and finally exit. When a SuperConnector leaves, the relationships that ran through them leave too. None of this appears in the deal model. It surfaces 12 to 18 months later as slipping synergies or unexplained attrition.
AI is raising the stakes. AI-native companies run on far smaller teams, so each person carries more of the relational infrastructure; workflows can be captured in systems the buyer owns, trust in a particular person cannot. And in founder-led companies, the founder is usually the biggest SuperConnector in the building. The real diligence question is not whether the founder will stay, but how much of the network leaves with them.
What this looks like in a real deal
When the 126-year-old Danish logistics group LEMAN acquired Nauta SA, a Swiss company with more than 80 employees across six offices, a network analysis of both companies plotted every employee by seniority against network influence.
The map showed what the org chart could not. Some formal leaders had strong network influence; others had surprisingly little. And 11 hidden SuperConnectors emerged across the two companies, people whose influence far outstripped their seniority and who would not have appeared on any conventional retention list.
Those 11 became the integration’s champions, working alongside the integration and people teams from the start, rather than being discovered months later through unexplained departures.
Carlos Meliá Christensen, an independent private equity advisor, reflects that his own integration plan was detailed and well thought out, but that engaging the key informal connectors up front would have created alignment far earlier and saved considerable time and friction.
The difference they make
Given a real role, SuperConnectors do three things no top-down communication plan can buy.
- They translate the deal. Colleagues who will not take the official version at face value will take it from someone they trust.
- They surface issues early. People confide in them, so they hear about friction, confusion and quiet plans to leave weeks before any survey does.
- They bring the fence-sitters along. Peer-to-peer influence moves the group waiting to see which way the wind blows in a way an all-hands never will.
The result is a network that stays intact through the transition, because the people it runs through are still there and still engaged.
A role, not a bonus
You do not retain a SuperConnector with a retention bonus. You retain them with a role.
SuperConnectors already feel responsible for their colleagues; nobody asks them to. A mandate, information and recognition turn an unsupported burden into the integration’s most effective lever, and stop the slide from stress into burnout and exit.
Network analysis in M&A is not new. What matters is what the map is used for. Much of the market maps a network to decide who to cut or who to use. Unio maps it to decide who to support, treating SuperConnectors as the people who carry the integration rather than a resource to extract from.
In practice that means building the role into the deal. A network scan before close shows how concentrated or distributed the relational infrastructure is, and whether that risk should be priced in. A shared integration hub goes live on day one. SuperConnectors from both companies are identified and activated with a clear mandate to work alongside the integration and people teams, then help lead colleague-driven conversations and events. The health of the network is tracked through the earn-out and beyond, long after the 100-day plan has ended.
The bottom line
When you buy a company, you buy the relationships inside it. The deal model sees formal authority; the value runs through informal influence. Finding, supporting and keeping the people who carry that influence is what lets the network hold through a merger without depending on any one person, the founder included.
Individuals can leave. The network must stay.
