Meet Kirsten,
Your SaaS Finance Partner
Hi, I'm Kirsten, Founder of SaaS Scaler. I specialise in turning operational complexity into competitive advantage for scaling tech companies.
With 18 years' experience across the UK, US and Japan (including 11 years Big 4, and 5+ years senior SaaS finance roles), I'm both a US CPA and ICAEW ACA qualified accountant with 14 years of deep US market experience.
From market entry strategies to post-M&A integration, I've helped companies navigate the financial complexities that come with rapid growth. I embed myself in clients' businesses to identify the real revenue, profit and cash drivers, then build clean systems that turn data into strategic advantage.
