Who We Are
Founding Story
S.I.A. Consultancy was founded by Inna Semenyuk, leveraging her 20 years of experience in audit, industry, consulting, and entrepreneurship. Recognising a gap in impactful, change-driven advisory services for scaling businesses and fast-growing SMEs, S.I.A. Consultancy focuses on innovative, vision-driven and collaborative financial solutions.
The firm's mission is to shift the perception of financials from compliance-focused tasks to essential decision-making tools. By providing reliable and insightful reports for all departments—not just top executives—S.I.A. Consultancy empowers businesses with actionable financial insights to drive growth and manage uncertainty.
S.I.A. Consultancy equips non-financial leaders to engage with numbers, trains teams to think like CFOs from entry level, and delivers high-quality financial reporting tailored for decision-making, strategic planning, and securing investments.
When We Needed
S.I.A. Consultancy was founded to advise growing companies on building financial strategies to safeguard assets, strengthen cash positions, plan investments, and withstand market volatilities.
We are a team of accountants, CFOs, and advisers focusing on working with SMEs, PE-backed businesses, and corporates.
As accountants, we manage businesses' day-to-day financial operations to support their business goals.
As CFOs, we provide fractional or interim executive support for companies during times of transition, change, or rapid growth.
As advisers, we combine our insights to transform business processes, systems, and controls, and, in turn, transform companies.
How We Are Different
We are advisers you want to work with, but not those you have to work with. Why?
We achieve breakthrough results for growing businesses looking to increase financial performance through unlocking operational efficiencies.
Rather than standard reports and metrics, our approach is guided by customised, advanced data-driven reports that truly drive businesses forward.
We're based in London, UK, and have been working with businesses around the world across multiple industries and niches.
