Approach & Philosophy
HWH Sport combines board-room expertise and legal know-how with a selective, relationship-driven approach to representation. The partners’ history at FC Basel and in Swiss football governance shapes a philosophy centred on stability, long-term planning and realistic pathway design rather than short-term trading.
On the scouting side, Sascha Fischer often stresses personality, professionalism and resilience alongside technical talent, while using data, video and close contact with academy staff to identify players who can move from Swiss youth football to top-five-league environments. In negotiations, HWH aims to create balanced structures, aligning player upside (development, playing time, salary progression) with club stability and financial sustainability, as seen in structured deals such as the Hoffenheim transfers.
Fees & Transparency
Public information does not disclose HWH Sport’s exact commission structure or fee model. In line with standard European practice and FIFA regulations, fees are typically structured as a percentage of player remuneration or transfer value, within regulatory caps, with dual representation used only where permitted and formally agreed.
Compliance & Reputation
Disciplinary actions / sanctions:
No public record of disciplinary sanctions against HWH Sport or its key agents up to November 2025.
Litigation / disputes:
No major public legal disputes involving HWH Sport as a defendant have been reported in mainstream Swiss or international sports media; the firm is primarily mentioned in relation to advisory and governance work.
Media sentiment:
Overall positive to neutral. Swiss press has described HWH as a new “power centre” in Swiss football advising players and coaches, which made parts of the traditional agent market nervous, but coverage focuses on their influence, professionalism and network rather than controversy.
Awards / Recognition
Formal agent-industry awards specific to HWH Sport are not publicly documented.
Founding partner Bernhard Heusler is widely recognised in Switzerland for his leadership at FC Basel and is frequently invited as a keynote speaker on management and team leadership, indirectly reinforcing the HWH brand.
Sascha Fischer’s appearances on leading German-language football business podcasts and coverage of multi-million-euro transfers have further raised the profile of HWH Sport within the DACH football ecosystem.
