Whether you need a seasoned international hand for six months or a structured market entry programme, we work as an extension of your team, not a distant adviser.
From market assessment through to first revenues. We handle regulatory landscaping, partner identification, pricing strategy, and early pipeline development in your target geography. Particularly strong across Europe, the Middle East, and the Americas.
An experienced business development director embedded in your senior team on a part-time or interim basis. Ideal for SMEs and scale-ups that need strategic commercial capability without a permanent overhead.
We deploy advanced AI tools to transform how you identify prospects, qualify opportunities, and manage your pipeline. Market intelligence, competitor mapping, and CRM enrichment delivered at a pace no traditional approach can match.
We work with technology companies, engineering firms, and specialist manufacturers whose sales cycles are long, whose buyers are technical, and whose markets are regulated. This is a world where credibility comes from knowing the domain, speaking the language, and understanding how procurement actually works.
Sebethos Advisory was founded on a straightforward premise: that too many capable companies underperform internationally because they lack the right commercial resource at the right time. We fill that gap with people who have done the work, not just advised on it.
We have carried a quota, run a P&L, and closed deals in difficult markets. Our advice is grounded in execution.
Every engagement follows a clear framework: qualify, plan, execute, measure. No ambiguity on deliverables or timelines.
AI-powered market intelligence and pipeline management give our clients a genuine edge in speed and depth of coverage.
