Meet Mark
Many strong technology and B2B companies don't struggle because of their product — they struggle with distribution. Getting in front of the right customers, partners, and decision-makers is often the real bottleneck.
Mark co-founded Lion Street Introducing Brokers and brings over a decade of experience in deal origination, structured finance introductions, and business development across financial services, SaaS, and real estate.
At LionStreet International Business Consulting, he works with SaaS platforms, technology providers, and growth-stage B2B firms to open doors — building partnerships, facilitating executive introductions, and supporting international expansion.

Our mission
Most B2B firms don't lack ambition — they lack access. Hiring a sales team takes months. Cold outreach without warm introductions burns trust. LionStreet exists to close that gap.
We operate as your business development function from day one: strategy, verified outreach, executive introductions, and close support — without the cost and risk of building in-house.
Based in Sydney, we serve firms targeting growth across Australia, APAC, and global markets — with particular depth in financial services, trade finance, and structured B2B sectors.
