SINCERIUS company logo


Financial services with an innovative approach.

SINCERIUS was founded from the desire to make due diligence more accessible, effective, and innovative. We combine the expertise & experience of the Big 4 with the agility & pricing of a boutique due-diligence firm.

Our clients mainly reach out to us to tackle financial challenges in the field of mergers and acquisitions (M&A). We handle over 150 acquisition due diligence and vendor support projects on a yearly basis, across a wide range of industries and client types.

Sincerity is built into our name and our approach. We believe that clear, honest advice is the foundation for well-informed decision-making.
