At GTM.io
Sidney Minassian is the Founder and CEO of GTM.io, a go-to-market operating firm for B2B product and services-led technology companies.
He leads the company with a clear mission: to build a trusted, performance-driven go-to-market firm, one that doesn’t just advise, but helps companies operate at a higher commercial standard.
As CEO, Sidney focuses on shaping the long-term direction of GTM.io, developing a strong and capable team, and defining the operating standards that underpin what “world-class GTM” looks like in practice.
For Sidney, building this organisation is about more than launching another venture.
He cares deeply about how it is built - the standards it holds, the depth of thinking behind its work, and the environment it creates for its people. He believes commercial rigour and human leadership reinforce each other, and that sustained performance comes when people feel trusted, challenged, and energised.
He is committed to building something that performs at a high level, is principled in how it operates, and creates genuine joy in the journey.
Before GTM.io
Sidney is a serial entrepreneur, CEO, and growth advisor with more than 25 years of experience building and scaling technology businesses across Australia and the United States.
He has experienced the full spectrum of company building, from venture-backed startups to services-led scale-ups, from rapid growth to hard resets, from acquisition to failure.
He was Founder & CEO of Contexti, later acquired by Versent. He also served as CEO of Saasyan, an AI-driven SaaS platform, and co-founded Liaise, a Silicon Valley NLP venture that raised capital and launched into the US market.
Beyond his operating roles, Sidney has worked closely with hundreds of founders and CEOs across the globe as an advisor and coach. He has helped them sharpen their go-to-market focus, strengthen commercial execution, and grow into the leaders their companies require.
His work spans early traction through to scale-stage growth, often sitting at the intersection of GTM clarity, strategic decision-making, and executive leadership under pressure.
This combination of lived operating experience and deep advisory exposure shapes how he builds today - with practical insight, commercial discipline, and a clear understanding of the pressure leaders carry.
Beyond GTM.io
He is known for introducing himself as “Sidney from Sydney.”
Married to an artist and a proud father of three, he considers leadership at home just as important as leadership in business - in both, how you show up matters more than what you say.
Sidney writes regularly, speaks globally, and is passionate about helping people expand their view of what they’re capable of - not just in performance, but in who they are becoming.
A proud Australian with Armenian heritage, he maintains strong ties to the Armenian tech ecosystem, both in Armenia and across the global diaspora.
He also loves to cook - rarely following recipes and drawing inspiration from the exceptional cooks on both sides of his family.
He approaches business and life as a long game and believes deeply that the universe has our back.
