Our offer
Helping financial actors and business leaders shape strategies that stand the test of the New Climate Era.
We work alongside investors, executives, and sustainability leaders to design credible strategies, align operations with long-term transitions, and strengthen equity stories. Our role is to bring clarity where complexity prevails, so that each client can act with purpose and resilience.
“What should be our investment ambitions and priorities in the next years?”Weastem helps CEOs step back from short-term targets to look at ambitions in the light of the New Climate Era. Through wide signal collection, market sounding, and structured workshops with the client’s team, we identify where real opportunities lie — ambitions that are both credible externally and anchored in the organization’s capacity to deliver.
“How could we position our next fund as an impact fund?”Positioning a fund as “impact” requires more than adopting a label. We help CEOs build the right foundations: starting with a deep understanding of the problems the fund seeks to address, and ensuring these are matched with the team’s actual skillset and investment approach. Through stakeholder mapping — from LP expectations to regulatory frameworks — we align ambition with execution, so that the impact narrative is both authentic and defensible. This is how we strengthen reputation and long-term credibility in a market where scrutiny is intensifying.
“What should be our next investment strategy, that
fit our overall business strategy and our sustainability credentials?”In the New Climate Era, sustainability is not a separate track —
it becomes the overarching lens for strategy and operations. We work with CEOs to analyze mega-trends and
systemic risks, framing investment choices around both value creation and value protection at the firm level.
By adding new skill sets, technology insights, and external partnerships, we help uncover pockets of value
invisible to traditional investment methods. This ensures strategies that are credible in today’s market
and resilient to tomorrow’s disruptions.
“How do we move from reporting and compliance to a real strategic role within the firm?”We help CSOs shift from compliance to influence by embedding sustainability into core strategy and decision-making. Through structured interviews with executives, mapping of internal dynamics, and analysis of systemic risks, we identify where sustainability can reshape value creation and risk management. This transforms the CSO role from reporting gatekeeper to strategic partner.
“How can we build an integrated sustainability roadmap that resonates with both our executive team and our investors?”We co-design roadmaps that balance ambition with credibility. By combining market sounding, stakeholder mapping, and scenario analysis, we ensure sustainability objectives are aligned with business strategy, investor expectations, and external realities. The result: a roadmap that speaks to both the boardroom and the market.
“How do we ensure our sustainability priorities translate into credible actions and measurable impact across business units and portfolios?”We provide operational support that links high-level priorities to day-to-day execution. This includes setting up impact metrics, leveraging technology for data and monitoring, and building partnerships with experts where internal capabilities fall short. Our role is to ensure priorities don’t remain abstract but turn into measurable, recognized results.
“How can we strengthen our equity story in a context of climate risk and increasing LP scrutiny?”Strengthening an equity story today is not about crafting a better narrative — it’s about building one that stands on solid ground. We work with deal teams to test the business model against climate and social megatrends, quantify risks and resilience factors, and assess alignment with LP priorities. By integrating stakeholder feedback, sector benchmarks, and scenario analysis, we help teams demonstrate not only why the story is credible, but how value creation and protection are embedded in the strategy.
“What hidden risks or opportunities should we surface in due diligence to protect and grow value over time?”Most of the time, ESG due diligence is not expected to focus on value creation — it is treated as a compliance exercise. At Weastem, we bring an integrated approach: assessing how environmental and social risks, as well as stakeholder pressures, may affect the company’s trajectory and financial resilience. We also look at opportunities linked to business model shifts — whether through strategic build-ups, divestments, or repositioning — that remain invisible in a traditional due diligence. This way, ESG / Sustainability analysis becomes a lever to protect value today and anticipate the transformations needed to grow it tomorrow.
“As investment bank, how can we accelerate transaction processes when ESG due diligence is becoming increasingly complex?”Too often, ESG issues are only addressed when the transaction is already under way — leaving room only for cosmetic adjustments. At Weastem, we bring these questions upstream. By opening the conversation early, we give companies time to act on their most material exposures, adapt business models where needed, and build credibility with buyers and LPs. This preparation turns ESG due diligence from a late-stage hurdle into a lever that accelerates the process and strengthens the equity story.
