Current Position
Jos Lazet is founder and Chief Executive Officer of Blockrise, a Bitcoin-focused financial-services business. Its June 2026 company announcement confirms his role and describes Blockrise as based in Rotterdam. The Netherlands is used as his primary professional market on that basis. The company offers Bitcoin trading and asset-management services; this profile does not describe it as a licensed bank.
Background & Biography
Blockrise’s author biography says Lazet has been involved with Bitcoin since 2013 and founded the business in 2017. His work has focused on the practical questions of storing and managing digital assets. In a September 2024 Start to Scale interview, produced by Up!Rotterdam and described by Blockrise, he discussed the company’s development and the challenges of growing a financial-technology business.
Notable Contributions
Lazet has helped develop Blockrise’s Bitcoin-focused service proposition and publicly explained changes to its business model. A June 2026 company announcement set out the removal of a performance fee from the Fundamentals strategy, following a custody-fee change. These are documented company decisions, not evidence of future investment returns. His earlier interview also discussed a longer-term banking-style ambition; an aspiration should not be confused with a banking authorization.
Why Katharos.ai Is Following Them
Katharos.ai follows Lazet because his work illustrates the choices facing businesses that combine Bitcoin ownership, trading access and asset management. The relationship between user control, custody arrangements and service-provider responsibilities is relevant beyond any single company. Coverage will examine how stated principles are reflected in documented products and terms.
Areas to Follow
Areas to follow include Bitcoin custody models, pricing changes, asset-management design and the relationship between separate group businesses. Clear distinctions between product availability, regulatory permissions and marketing claims are important. Katharos.ai will monitor verified operational announcements without treating a company’s security or investment objectives as guarantees.
Reporting Scope
Reporting focuses on professional statements, company documentation and primary regulatory records where relevant. Broader team achievements are not attributed to Lazet alone. This profile is not an endorsement or investment recommendation, and Katharos.ai does not independently guarantee the authenticity of every cited source. Role and professional-market details were checked on 20 October 2026.
