Matthias Tauber, who runs BCG across Europe, the Middle East, South America and Africa, built his career on a single idea: leadership is craftsmanship, not magic. After two decades scaling teams from a four-person practice to a region of thousands, he distils it into four lessons. Hire for culture, not credentials. Build the team before you need it. Address difficult things early. Manage your energy like you mean to finish the race.
Matthias Tauber leads Boston Consulting Group’s operations across Europe, the Middle East, South America and Africa. A civil engineer by training, he built BCG’s building materials and construction practice from a blank sheet and is now responsible for thousands of people across one of the firm’s biggest regions.
In a recent Foundamental University masterclass, he laid out the four lessons he keeps coming back to. Not abstractions. Just the things that compounded into something that worked.
If you’re a founder building in construction tech, a project director scaling a regional office, or a CEO trying to make a team of fifty feel like a team rather than fifty people with the same email domain, the mechanics are identical. The industry context changes. The leadership work doesn’t.
Four lessons, one integrated system: hiring, team building, difficult conversations, energy management. Each one matters. None of them work alone.
Lesson 1: Hire for culture, then performance
Why three non-negotiables matter more than the CV
When Tauber set out to build BCG’s building materials and construction team, the people he wanted had options. So he flipped the equation. Rather than competing on prestige, he competed on culture. He defined three non-negotiables: candidates had to take care of themselves and each other, hold a genuinely high performance bar, and connect with the industry. Industry knowledge was deprioritized. It could be learned. The other three couldn’t.
This matters more now than when he started. With AI reshaping how work gets done, adaptability has become a bigger predictor of success than static domain expertise. A candidate already using AI tools to rebuild their own workflows is showing the trait Tauber wants: willingness to learn, even when their established way of working seems fine.
Industry knowledge can be learned. The traits that define how a team works together cannot be retrofitted.Matthias Tauber, Senior Partner, BCG
Practical advice: when you interview, look for inconsistencies between what people say and what their track record shows. If they don’t match, that’s a signal worth paying attention to. The first ten people define the culture of the next hundred.
Lesson 2: Individuals are not a team. Build one anyway
The hard side, the soft side, and the rule of one-third
You hire well. You now have a group of strong individuals. None of that automatically makes them a team. Tauber learned this from a senior partner on his very first project, who explained why he spent so much time assembling the right people: “My main contribution is to get the right people in and then take it from there.”
The leader’s job after hiring splits into two parts. The hard side is clarifying roles and what’s out of scope. Sounds simple, rarely is. Overlapping responsibilities create big problems further down the road. The soft side is psychological safety paired with a high performance bar. It needs to be safe to speak up. It cannot be safe to underperform.
That combination is also what Google’s Project Aristotle research found when analyzing 180 teams. Psychological safety was the single biggest predictor of team effectiveness, and it works because people are willing to challenge each other, not because they’re shielded from challenge.
- One-third social. Time spent outside the meeting room is the foundation of psychological safety inside it.
- One-third shared agenda. The topics the leader needs to drive with the team. The visible work.
- One-third context and learning. Senior people need shared context to make independent decisions later, without escalating everything.
Build the team before you need it, because the moment you need it, it’s too late.

Feedback as a duty, not a favor
Tauber tells a story he clearly doesn’t enjoy telling. He once had a team member who treated male and female colleagues differently. He noticed. He let it slide for a few days because the conversation felt uncomfortable. By the time he addressed it, a woman on the team had already approached him to say she wasn’t comfortable. He fixed it, but he knew he was a few days late, and those few days mattered.
His reflection is direct. When he asks senior leaders what they’d do differently, almost everyone says the same thing: they didn’t act fast enough. A small thing that’s easy to correct early becomes the root cause of a bigger crisis later. Two things make feedback work: timely (address it when you observe it) and specific (point to the situation, describe what could have been done differently). That’s when it stops being criticism and becomes a gift.
Feedback is a gift. You may sometimes not feel that way. It is.Matthias Tauber, Senior Partner, BCG
Lesson 4: Manage your energy like the marathon it is
Physical, emotional, and the why underneath
You can hire well, build the team, address the hard stuff, and still fail. The reason is energy. If a leader stops radiating energy, the rest of the organization stops having any. The physical side is basic and most people still don’t do it. Sleep, eat well, exercise. Tauber’s tactical advice: don’t overthink it and don’t be overly ambitious. The founder who responds to “you should exercise” by signing up for a marathon usually doesn’t make it past week three.
The emotional side is harder. Tauber tells the story of two CEOs leading their companies through the global financial crisis. Both worked hard. Both took care of themselves. One succeeded, the other didn’t. The difference was the “why”. The leader who made it through had a deep emotional connection to the company and a specific reason he wanted to make it work. The other did the right things mechanically, and people could tell.
People see through actions that aren’t anchored to a real reason. Doing the right things because you’ve learned to do them is different from doing them because you have a why. The why gives you the energy to keep going when the situation gets hard.
How the four lessons fit together
An integrated system, not a checklist
None of these lessons works on its own. Hire well without building a team and you have nothing. Build a great team without addressing difficult things and it falls apart. Do all of that but burn out, and you lose the team anyway. For ConTech founders: your first ten hires define what the next hundred look like. The difficult conversations you’re avoiding are the ones costing you the most. Your personal energy is a leading indicator of organizational energy.
For construction executives, the same applies with the labor crisis as backdrop. With 92% of contractors reporting difficulty filling open positions, retention matters more than ever, and retention is downstream of culture. Hiring for culture becomes a competitive advantage. Building the team properly becomes the difference between staff who stay and staff who leave for a competitor offering the same money.
The four lessons at a glance
| Lesson | What it means in practice | Where founders get this wrong |
|---|---|---|
| Hire for culture, then performance | Three non-negotiables defined upfront. Industry knowledge deprioritized. Adaptability over expertise. | Hiring for the CV. Tolerating cultural mismatches because the resume is strong. |
| Build the team before you need it | Hard side (roles, swim lanes) plus soft side (psychological safety, high performance bar). Rule of one-third. | Assuming a small team doesn’t need structure. Skipping the in-person time. |
| Address difficult things early | Timely, specific, actionable feedback. Reverse bad people decisions fast. | Waiting because the conversation feels uncomfortable. Hoping it resolves itself. |
| Manage your energy | Physical basics plus a why that connects you emotionally to the work. | Treating self-care as optional. Doing the right things mechanically. |

A civil engineer by training, he built BCG’s building materials and construction practice from scratch and has spent more than two decades advising leaders across the project economy. His lessons translate directly to ConTech because the mechanics of scaling a team are the same whether you’re growing a consulting practice or a software business. (Source)
It means defining three or four non-negotiable traits upfront and refusing to compromise on them, even when a strong CV is in front of you. For Tauber, those traits were taking care of others, holding a high performance bar, and connecting with the industry. Industry-specific knowledge was deprioritized because it could be learned. Interview practice should include connecting answers to facts on the CV, since inconsistencies are an early warning sign. (Source)
Google’s Project Aristotle studied 180 teams and found psychological safety was the single biggest predictor of team effectiveness, ahead of individual skill, seniority, or team size. The mechanism is straightforward: if people feel safe to speak up, ask questions, admit mistakes and challenge ideas, the team makes better decisions and learns faster. Tauber pairs psychological safety with a high performance bar, so it’s safe to speak up but not safe to underperform. (Source)
Two things matter. Timeliness, meaning you address the issue when you observe it rather than letting it accumulate. And specificity, meaning you point to the situation, describe what could have been done differently, and make the feedback actionable. Abstract feedback rarely changes behavior. Specific, timely feedback usually does. Tauber’s broader point is that delivering feedback is a duty, not a favor, because waiting only makes the eventual conversation harder. (Source)
Tauber describes energy as having two components: physical (sleep, food, exercise) and emotional (connection to a deeper reason for the work). Both flow from the leader outward. If the leader stops radiating energy, the rest of the organization quickly loses it. The emotional side is harder than it sounds, because acting the right way without a genuine reason behind it is something people can usually sense. Founders who connect their day-to-day to a real why tend to last longer and pull more out of their teams. (Source)
The 2025 AGC and NCCER workforce survey found that 92% of contractors are struggling to fill open positions, with labor shortages cited as the leading cause of project delays. In that environment, the cost of losing a good employee compounds, and culture becomes a more important retention tool than compensation alone. Tauber’s emphasis on hiring for culture and building genuine team cohesion is less an HR exercise and more a strategic response to a tightening labor market. (Source)
