The Evolution of Chair in the Lab-to-Market Journey
Deep Tech boards are not like other company boards. It is up to the Chair to make this clear.
From the outside, the Chair’s job in a Deep Tech company appears like that of any other company: run board meetings, support the CEO, represent shareholders, maintain good governance. Such expectations persist from early formation through eventual scale.
Upon closer look, however, the role of Chair in Deep Tech is a critical, phase-dependent position, similar to any executive role. It changes not merely in scope but in kind as the company progresses from early scientific promise to commercial credibility. And when the Chair role is misaligned with the company’s actual position in the Lab-to-Market journey, the consequences can be severe. Chairs shape the conditions under which every other leader’s decisions are made.
A weak or misaligned Chair creates an environment in which failures accumulate: leadership transitions get delayed, uncomfortable conversations are avoided, the CEO is unsupported or undermined, and the board oscillates between passivity and panic. Understanding how and why requires looking more carefully at what the role actually demands at each stage.
The Chair Shapes the Conversation
Let’s start with a useful reframing: in Deep Tech, the Chair’s primary role is not to run the company, advise the CEO, or represent investors. The primary role is to govern the quality and timing of the conversations that determine whether leadership, capital, and commitment are aligned with the company’s actual stage of development and risk profile.
Where the CEO orchestrates the resolution of risk across the organisation, the Chair orchestrates the resolution of risk at the governance level. They ensure the board is asking the right questions at the right time, that the CEO is being held accountable for the right things in the right phase, that leadership transitions are framed as structural necessities rather than personal failures, and that the distance between boardroom narrative and operational reality does not grow unmanageably wide.
This is what differentiates the Deep Tech Chair from the Chair of a conventional growth company. In a software or services business, the Chair can often rely on familiar metrics: revenue growth, customer acquisition, margin expansion. In Deep Tech, the metrics that matter change as the dominant risk changes — and the Chair must ensure the board’s perspective and questions changes with them. A Chair who governs a Phase III as though it were Phase I company, or a Phase I company as though it were Phase III company, will damage the company regardless of their intelligence or intentions.
The Core Principle
A Chair’s effectiveness is determined by whether the board’s expectations match the company’s phase — and whether the Chair has the judgement and authority to reset those expectations when they do not.
Most governance failures in Deep Tech have less to do with failures of oversight. More often, they are failures of calibration. For example, boards that demand revenue before qualification risk is resolved. Boards that tolerate scientific exploration after the company needs manufacturing discipline. Boards that personalise phase transitions as performance issues. Boards that defer to the CEO when they should challenge, or challenge when they should support. In every case, the Chair is the person best positioned to prevent the mismatch — and in every case, the Chair’s failure to act is the proximate cause of the governance failure.
Understanding this principle helps leadership teams, investors, and the Chairs themselves answer four practical questions at each stage of the journey:
What is the board’s primary governance responsibility right now?
What does the Chair need to ensure the board is actually doing what it needs to be doing?
What skills, relationships, and authority does the Chair require?
When should the Chair role itself be reconsidered?
Phase I: Guardian of Legitimacy and Learning
In the earliest stages — early TRL, pre-MRL — the company’s existence depends on scientific credibility, early capital, and the founder’s ability to attract talent. The board, if one exists at all, is typically small. Governance is informal. The Chair, if the role is formalised at all, exists to protect the company’s right to learn.
The Chair’s mandate during this phase is to:
Ensure the board does not import expectations from later stages;
Resist investor pressure for premature commercial milestones;
Validate that learning, and not delivery, is the legitimate goal;
Protect the CEO from noise that distracts from the core scientific and technical work;
Ensure capital structures preserve optionality; and
Recruit board members (when appropriate) for judgement rather than pattern recognition.
At this stage, the Chair is often a senior figure with scientific credibility or Deep Tech experience who can provide the founder with cover and counsel. The relationship is typically close, informal, and supportive. The Chair’s most important contribution is often what they prevent: the premature imposition of structure, metrics, or accountability frameworks that constrain learning before the company understands what it is building.
Important skills include scientific or technical credibility sufficient to assess early claims, comfort with genuine uncertainty rather than manufactured confidence, experience with Deep Tech capital structures, and the temperament to be patient.
The red flag is a Chair who governs through conventional startup metrics — pushing for go-to-market strategy, revenue forecasts, or operational KPIs before the technology is understood. Equally dangerous is a Chair who is entirely passive, providing no governance at all and allowing the founder to operate without meaningful board engagement. The diagnostic question for this phase: “What would it be irresponsible to promise right now?” If the board cannot answer this clearly, the Chair is not doing their job.
Phase II: Enabler of Coherence and Translation
As the technology stabilises — late TRL, early MRL — the dominant challenge shifts from existence to coherence. At this stage, the organisation must begin to make sense of itself. Early partnerships and commercial conversations introduce new complexity. Leadership roles that were fluid must become defined. The board must begin to function as a governance body, not merely a support group.
As such, the Chair’s mandate now shifts to enabling coherence without forcing premature rigidity. This is the phase where the Chair’s relationship management skills become critical, because the conversations that need to happen are often the ones that most would prefer to avoid.
The Chair must now:
Support early leadership evolution by encouraging explicit role definition and authority boundaries, particularly in Technology, Engineering, and Commercial;
Help the CEO separate narrative optimism from operational truth, stress-testing the company’s story without undermining the CEO’s credibility externally;
Begin preparing the board for the leadership transitions that Phase III will likely require, socialising the idea that changes in leadership are signals of maturity rather than failure; and
Manage the evolving relationship between the founder and the board, which often becomes strained as the company’s needs begin to diverge from the founder’s natural strengths.
This last point deserves emphasis. In Phase II, the founder-CEO relationship with the board is typically still personal and trust-based. The Chair’s job is to begin professionalising this relationship without destroying the trust on which it was built. This is delicate work, and it requires a Chair who can hold both the founder’s perspective and the company’s institutional needs simultaneously.
The skills that matter are organisational judgement, emotional intelligence, comfort with ambiguity, experience managing founder dynamics, and the ability to facilitate difficult conversations without either forcing conclusions or allowing avoidance.
The red flag is a Chair who allows leadership misalignments to be discussed privately but never addressed formally. Equally, a Chair who treats early pilots, partnerships, or letters of intent as proof of commercial readiness, reinforcing a narrative that flatters the board rather than informing it. The diagnostic question: “Where are we still behaving like a research group, and where are we pretending to be a company?”
Phase III: Architect of Accountability and Transition
This is one of the most critical governance phases in Deep Tech. The technology works, sometimes. Customers are cautiously interested. Capital is conditionally available. The company must now trade optionality for credibility, making commitments that are difficult or impossible to reverse. Leadership transitions are unavoidable. Deals introduce real downside risk. As such, the board must shift from enabling to governing.
The Chair’s mandate at this stage is to:
Ensure the board forces explicit trade-offs rather than allowing them to happen by default, which means driving clarity on what the company will and will not pursue;
Support the CEO in freezing parts of the system to enable scale-up;
Back leadership transitions in Engineering, Operations, Commercial, and Finance;
Ensure that major deals receive genuine cross-functional scrutiny before board approval; and
Hold the CEO accountable for the quality of commitments rather than the quantity of opportunities.
This is also the phase where the Chair is likely to have to manage the most sensitive leadership question in Deep Tech: the founder transition. Whether the founder-CEO needs to evolve, be complemented, or be succeeded, the Chair is the person who must lead this conversation. Handled well, the transition preserves scientific legitimacy, retains irreplaceable knowledge, unlocks execution capability, and signals institutional maturity. Handled badly, it destroys trust, triggers talent attrition, splits the board, and creates a false narrative of failure.
The difference almost always comes down to framing. The Chair who frames the transition as “Is the founder good enough?” will damage the company. The Chair who frames it as “What kind of leadership does the current phase require, and how do we configure it?” will create the conditions for a constructive outcome.
The Chair skills that matter are governance authority and credibility, deep experience with leadership transitions, comfort with conflict and discomfort, deal-level scrutiny, and the judgement to distinguish between healthy challenge and destructive interference. This is typically where a Chair with prior experience as a CEO, executive Chair, or senior board member in Deep Tech or capital-intensive industries adds the most value.
The red flag is a Chair who allows deals to proceed because “we’ll figure it out later,” who personalises phase transitions as performance issues, who demands speed without accepting constraint, or who penalises leaders for surfacing risk early. The diagnostic questions: “What becomes irreversible if this goes wrong?” and “Who carries the downside if this fails?” If the board cannot answer these clearly, governance has failed — and the failure belongs to the Chair.
Phase IV: Designer of Endurance
Once the company achieves real commercial traction — CRL-dominant, post-validation — the Chair’s role shifts from enabling survival to ensuring institutional endurance. The challenge is no longer whether the company can work but whether it can scale without breaking its culture, governance, or innovation capacity.
The Chair’s mandate now centres on:
Building governance that can outlast any individual leader;
Ensuring the board has the range of experience required for an operating company rather than a startup;
Overseeing CEO succession planning as a standing governance discipline;
Ensuring capital allocation is governed with rigour, preventing the company from over-expanding into markets or geographies before the organisation can support it; and
Protecting the company’s innovation capacity, ensuring that the urgency of scaling does not quietly destroy the scientific or technical capability that created the company’s advantage.
At this stage, the Chair’s profile itself often needs to change. The early-stage Chair who provided scientific credibility and founder support may not be the right Chair for governing a scaled operating company. This transition is as important as any leadership transition in the management team, and it is often neglected. Boards that recognise this and plan for Chair succession alongside CEO succession are significantly better governed.
The skills that matter are institutional governance experience, board composition and renewal expertise, CEO succession planning, capital allocation oversight, and the temperament to govern for the long term rather than optimise for the next fundraise or quarterly result.
The red flag is a Chair who confuses governance with management, intervening in operational decisions rather than ensuring the management team is configured to make them well. Equally, a Chair who allows growth to outpace organisational readiness, or who treats the company’s public narrative as more important than its internal resilience. The diagnostic question: “What would break if we doubled tomorrow?”
The Central Truth
Across all phases, the L2M Chair Leadership Model clarifies one central truth: the Chair’s role should evolve when the governance challenge changes and not when the current Chair “fails.”
Most governance failures attributed to “weak boards” are, in fact, failures of Chair calibration. The board asked the wrong questions because the Chair set the wrong agenda. The CEO was held to the wrong standard because the Chair did not reset expectations. Leadership transitions were delayed because the Chair avoided the conversation. Deals were approved without scrutiny because the Chair did not insist on it.
The Chair does not need to be the smartest person in the room, but they do need to be the person who ensures the room is asking the right questions for the phase the company is actually in.
The Chair-CEO Relationship: The Defining Dynamic
No other relationship in the governance structure matters as much as the one between Chair and CEO. In Deep Tech, this relationship is uniquely demanding because it must evolve through phases that place fundamentally different pressures on both roles.
In Phase I, the relationship is typically personal and supportive. The Chair provides cover and counsel. The CEO provides vision and credibility. Trust is high and formality is low.
In Phase II, the relationship must begin to professionalise. The Chair must start challenging the CEO’s narrative constructively, introducing rigour without destroying trust.
In Phase III, the relationship faces its greatest test. The Chair must hold the CEO accountable for commitments, support leadership transitions that may include the CEO’s own role, and maintain the CEO’s authority externally while challenging them privately.
In Phase IV, the relationship must become institutional — sustainable beyond any individual, embedded in governance processes rather than personal rapport.
Each of these transitions is difficult. Chairs who are unable to evolve the relationship — who remain the founder’s protector when the company needs a governance leader, or who become adversarial when the CEO needs support — damage the company in ways that are difficult to reverse. The best Deep Tech Chairs maintain a consistent posture throughout: honest, supportive, rigorous, and phase-aware. They are neither the CEO’s ally nor their adversary. They are the custodian of the conditions under which the CEO can succeed.
Why the Best Look Different in Deep Tech
Across the Lab-to-Market journey, the best Deep Tech Chairs share a distinctive set of characteristics that separate them from effective Chairs in conventional industries.
They are comfortable with genuine uncertainty; not the managed uncertainty of a diversified corporation, but the existential uncertainty of a company whose core technology may not work. They understand that timelines in Deep Tech are not negotiable through better management; they are constrained by physics, regulation, and qualification cycles that no amount of board pressure will accelerate. They recognise that leadership transitions are structural features of the journey, not evidence of hiring mistakes. They can distinguish between a CEO who is failing and a CEO who is leading through a phase that looks like failure from the outside. And they have the courage to act on that distinction, supporting the CEO when the board wants to blame, and challenging the CEO when the board wants to defer.
Most importantly, the best Deep Tech Chairs govern with reality rather than against it. They do not wish the company were further along. They do not benchmark against irrelevant comparables. They do not confuse narrative momentum with operational progress. They accept the company as it actually is, and they ensure the board does the same.
