Navigating change.
Creating sustainable value.


Lembos is a sustainability advisory firm for private equity and alternative investors, financial institutions and mid-market companies across Europe, with an international private markets perspective.

Our purpose

Sustainability is now part of the investment decision.


Sustainability has become part of investment decisions, portfolio management, risk oversight and corporate strategy.

For investors, it shapes due diligence, LP communication, reporting expectations, portfolio engagement and exit readiness. For companies, it affects governance, customer requirements, access to capital, employee expectations and long-term competitiveness.

Lembos Advisory helps clients translate sustainability requirements and opportunities into practical action — with a focus on clarity, proportionality and commercial relevance.

Our work is built on hands-on private markets experience, including ESG support across investment platforms representing more than EUR 5bn in assets under management.

Who we work with

Investors and companies navigating the same shift.


We work with three groups whose sustainability questions overlap, but whose answers rarely do.

Private equity and alternative investors

We support private equity firms, private credit investors, infrastructure funds, venture and growth investors, funds of funds, family offices and hedge funds.

Typical needs: ESG due diligence, investment committee input, portfolio monitoring, LP reporting, investor communication, value creation and exit readiness.

Mid-market companies

We advise mid-market companies across sectors on sustainability strategy, ESG data, reporting, governance and practical implementation.

Typical needs: ESG strategy, data collection, reporting readiness, governance structures, customer requirements, operational improvements and stakeholder communication.

Financial institutions

We support financial institutions, including banks, insurers, asset managers and other financial services providers.

Typical needs: ESG-related strategy, reporting, investment processes, risk management, governance, stakeholder communication and sustainability data processes.

Clarity for the decisions that shape lasting value.


Practical sustainability advice for investors and companies.

Thoughtful guidance. Practical solutions. Enduring impact.

Why it matters

Not only compliant. Useful.


Sustainability expectations are increasing — from investors, regulators, customers, employees and other stakeholders.

At the same time, ESG work often becomes too complex, fragmented or disconnected from commercial priorities.

Lembos Advisory helps clients create structure, focus and clarity.

We support sustainability work that is not only compliant, but useful: improving decision-making, strengthening investor confidence, managing risk and contributing to long-term value creation.
