Beyond Founder-Led Scale Most software companies don't stall because of product. They stall because the commercial model that got them to £10M, £20M or £50M ARR no longer scales cleanly.

👉 Sales cycles lengthen👉 Forecasts become less reliable👉 Expansion plans underperform👉 The founder remains involved in too many critical deals What feels like a growth problem is often an operating model problem. At Slipstream GTM, we help operational software companies scale beyond founder-led growth before commercial friction becomes structural. What makes our model different is that diagnosis, execution and leadership are aligned from day one. Historically, companies hired a consultant to identify the problem, a recruiter to find talent and a sales leader to execute the transformation. The challenge was that accountability became fragmented. We align all three. Unlike traditional advisory firms, our view of the market is informed by executive search mandates, giving us real-time visibility into GTM leadership, compensation, expansion patterns and commercial failure points across enterprise software. Our starting point is typically the Expansion Readiness Diagnostic - a structured assessment designed to identify the commercial, leadership and expansion risks most likely to constrain scale. The output is a Commercial Maturity Score, Scaling Risk Map and a clear set of priorities for the next 12 months of growth. We typically work with founder-led and investor-backed software companies between $10M and $100M ARR, particularly those navigating international expansion, increasing GTM complexity or the transition to institutional scale. Operational software is our focus because pattern recognition compounds faster in concentrated markets than it does across generalist SaaS. ✅ Supply Chain & Logistics Software ✅ Workforce Management & Operations Software ✅ Operational AI platforms✅ Enterprise SaaS   Through 15 years of executive search, I've been embedded in dozens of GTM leadership transitions, expansion programmes and commercial transformations across enterprise software. That pattern recognition now informs every engagement. Through 15 years of executive search, I've delivered 250+ GTM hires globally, who have remained in role for an average of 7 years. I've helped build commercial teams at every growth stage, from pre-revenue through to public-company scale - more details in my role If you're seeing signs that founder-led growth is no longer scaling cleanly, it's probably worth a 📱 +44 (0)739 8670 589
