Background

Jeroen De Wit is the co-founder and CEO of Teamleader, a Ghent-based SaaS company offering all-in-one CRM, invoicing and project management software to SMEs 12. He started Teamleader in 2012 and grew it to serve 35,000+ customers across Europe before Visma acquired it in June 2022; De Wit continued as Managing Director of Teamleader within the Visma family 12. Alongside Teamleader, he angel-invests in Belgian early-stage technology companies 34.

Stated Thesis

No publicly documented stated thesis was found. Per third-party angel directories, De Wit “supports early-stage technology companies in Belgium” with a focus on artificial intelligence, CRM, and legal tech sectors at seed and early stages 34.

Inferred Thesis

Sample size is small (11 publicly tracked angel investments per Tracxn and Investorlist 34) so percentages are not meaningful. Qualitative patterns:

  • Geography: Heavily Belgium-focused. Most named portfolio companies (Aikido, Donna, Jurimesh, IntelliProve, Polysense, Exhibitly) are Belgian 345.
  • Stage: Predominantly seed and pre-seed, with check sizes consistent with European angel rounds (€25K-€100K range based on round sizes of €1-2M with 7-22 co-investors per round) 567.
  • Sector: B2B SaaS skew (Teamleader-adjacent), with notable concentration in vertical SaaS (legaltech via Jurimesh, healthtech via IntelliProve, security via Aikido), AI, and CRM 34.
  • Co-investor patterns: Frequently co-invests alongside other Belgian SaaS founders-turned-angels including Anthony De Clerck (Aikido CEO), Andreas De Neve (Teamtailor), Gilles Mattelin, and Christophe Morbee — a tight Ghent/Belgium angel network 567.
