Frequently asked questions

What investment stages does LeanSquare target?

LeanSquare concentrates on early-stage equity, specifically seed and start-up rounds. The firm enters at company formation or first institutional capital deployment, and may participate in follow-on growth rounds for existing portfolio companies. It does not operate as a late-stage or buyout investor.

Which sectors does LeanSquare focus on?

LeanSquare's investment activity is oriented toward digital and technology companies, with an emphasis on enterprise software, digital platforms, and tech-enabled services. The firm does not publicly maintain an exclusion list, but its deal history shows no exposure to heavy industry, traditional manufacturing, or natural resources.

Does LeanSquare invest outside Belgium?

LeanSquare's core geographic mandate is Wallonia and the broader Belgian market. While its investment perimeter may extend to neighboring Benelux countries, the firm's identity and sourcing network are anchored in the French-speaking Belgian ecosystem, where proximity to founders and regional innovation clusters informs deal selection.

Is LeanSquare structured as a fund or a holding company?

LeanSquare operates as a private equity vehicle making direct equity investments into portfolio companies. It has not publicly disclosed a formal multi-fund structure or limited-partner fundraising rounds. The firm's lean operational footprint suggests a concentrated vehicle rather than a diversified fund-of-funds platform.

How does LeanSquare source its deals?

Leveraging its deep roots in the Liège and Walloon startup ecosystem, LeanSquare sources primarily through local founder networks, university spin-off channels, and regional technology hubs. Its small-team, high-proximity model gives it early visibility into seed-stage opportunities that larger Brussels- or Flanders-based funds may overlook.
