Fractional CFO [40-60%], Remote

About You

The Fractional CFO will help build and operate Optiml’s financial operating system during a critical scale-up phase.

This role combines strategic financial leadership with hands-on operational execution, ensuring that the company maintains strong financial discipline, liquidity visibility, and investor-ready reporting while scaling its B2B SaaS business.

Working closely with the CEO and leadership team, the Fractional CFO will oversee outsourced accounting partners, establish structured financial processes, and introduce pragmatic automation that reduces manual work and improves financial transparency.

A key focus of the role is ensuring high data consistency across finance, operations, and commercial teams, enabling leadership to make faster and better-informed decisions.

The role also includes financial coordination across Optiml’s Swiss parent company and its international subsidiaries (Germany and the UK, with potential other expansions), ensuring clean consolidation, governance, and scalable processes as the company grows.

About Optiml

Optiml is revolutionizing real estate with our Real Estate Decision Intelligence (REDI) software—a new class of decision technology that embeds AI to help decarbonize buildings while optimizing asset financial performance.

We are an ETH Zurich spin-off that launched our first product in April 2024 and are now scaling across Europe and the US. We recently raised an oversubscribed €8M Seed round to accelerate our growth, supported by leading VCs such as KOMPAS, Planet A Ventures, Innovation Endeavors (the fund of former Google CEO Eric Schmidt), BitStone Capital, and The Bau Ventures, along with leading angels.

Built on more than a decade of research and proprietary IP, our platform enables institutional investors, owners, and asset managers to make underwritable, forward-looking decisions across the full asset lifecycle — from acquisition to exit — replacing static, backward-looking reports with actionable intelligence.

Trusted by leading organizations across Europe and beyond, Optiml supports capital allocation decisions that balance key financial, regulatory, and sustainable considerations under real-world constraints.

As of early 2026, we are expanding our team to scale our product capabilities and operational delivery as we work to make Real Estate Decision Intelligence the global standard for real estate investment decision-making.
