Our clients
Corporates, SMEs and start-ups —
three situations, one standard of excellence.
Nesium adapts its intervention to your reality. No standard solution: a diagnosis, a network, a tailored response.
Segment 01
Corporates —
Management under pressure
Large organisations · Operational crisis
For larger entities whose management is facing an operational crisis, a governance deficit or a complex transition. Nesium steps in as a rapid executive reinforcement — with discretion and efficiency. No lengthy diagnosis — immediate engagement, result-oriented.
Typical warning signs
- Vacant or conflicted senior management
- Sharply deteriorating financial results
- Governance crisis between shareholders and management
- Strategic project stalled due to lack of resources
Segment 02
SMEs —
Without a formal board
Swiss SMEs · Governance to be structured
Most Swiss SMEs have neither a structured board of directors nor a full C-suite. Nesium fills that gap: a trusted strategic and operational partner, available part-time, without the cost of a senior hire. An external perspective that changes everything.
Typical warning signs
- Isolated founder with no structured external perspective
- Rapid growth without adequate organisation
- Acquisition or external growth projects underway
- Need for credibility with banks or investors
Segment 03
Start-ups —
From idea to scale-up
Launch · Restructuring · Fundraising
Start-up founders need experienced support from the earliest stages: structuring the company, preparing a professional board, pitching investors, or navigating a pivot or restructuring phase. Nesium is that executive sparring partner.
Typical warning signs
- Need to structure governance ahead of a fundraise
- Solo founder looking for an executive sparring partner
- Post-seed operational industrialisation phase
- Pivot or post-crisis restructuring situation
