Make European Expansion Your Series A Edge

Great Circle Growth designs European expansion strategies that help early-stage US B2B tech companies maximise fundraising outcomes.

GCG Summary

In a funding environment where AI is redefining expectations for data literacy, market readiness, and go-to-market execution, GCG ensures partners surpass benchmarks with clarity and confidence.

We support early-stage US B2B tech companies nearing Series A, build ambitious, data-centric, European expansion strategies.

With 20 years of EMEA scaling experience, including Twitch's growth to category leadership and integration with Amazon Advertising's global operations, we partner with ambitious teams to solve complex challenges and drive revenue growth. Our approach is based on embedding scalable practices across people, processes, and technology.

Why We Exist

GCG was built to bridge the gap between US market validation and European sales expansion.

Investors Expect Expansion Readiness.
Approaching Series A, investors expect a credible plan for international sales expansion, even if execution is 12-18 months out.  Without prior exits or embedded experience, many founding teams lack the proof points to justify their expansion strategy.

Europe is Critical, But Complex.
Europe is the second-largest addressable market after the US. However, Europe comprises 44 countries, 27 currencies, and 24 languages. Entering the region without a clear strategy is challenging for founding teams with competing priorities and limited experience.

Sustainable Beats Fast.
Mistimed or poorly managed expansion can lead to organisational complexity, wasted capital, and negative customer experiences.  In contrast, sales growth supported by a well-defined and sustainable strategy demonstrates discipline, ambition, and strong execution; three key factors evaluated by Series A investors.

What We Do

We act as an embedded international growth function, bringing clarity to your Series A preparation.

Turn Strategy Into Investor Confidence.

Investor Blueprint

Even with limited data, early-stage businesses can gain valuable insights. We help you identify the key drivers of your growth, focusing on how inputs affect expected outputs, and contextualising that data for the European market.

We translate these insights into a strategic plan for expanding into Europe, which includes revenue projections, risk assessments, and a practical go-to-market roadmap.
