Five transactions from H1 2026 analysed through the CIFSO v4.0 lens. From Windsor.ai to OneStream — what worked, what did not, and what each grade would have signalled.
Five transactions from H1 2026 analysed through the CIFSO lens. What worked, what did not, and what each grade would have signalled.
team.blue × Windsor.ai (Switzerland, Q1 2026) represents the archetype of a clean AI acquisition. Windsor.ai's dataset was proprietary, its IP stack clean, and its NRR above 130%. An estimated CIFSO grade of AA reflects the quality of preparation — not just the product. The transaction closed at an estimated 7–10x ARR, a premium to the FinTech median.
Hg × OneStream (UK/EU, Q1 2026) is the defining upper mid-market deal of the period. OneStream's position as a category leader in financial performance management, combined with mission-critical enterprise embedding and PE-grade financial documentation, puts this firmly in AAA territory. The estimated multiple of 12–15x ARR reflects the premium for category leadership.
The French LegalTech (Q2 2026) is a case study in how a Grade A asset transacts. Contract automation, RGPD-compliant architecture, and verifiable accuracy metrics — but limited scale and no AI-native moat. The 4.5x ARR multiple is fair for the grade. The deal closed in 74 days from mandate — faster than the market median.
The German HR Automation SaaS (Q1 2026) demonstrates the value of a clean cap table. Single founder, no convertibles, SAP integration creating switching costs, and a documented transition plan. Grade A with a 3.8x multiple reflects accurate market pricing for the segment.
The Dutch HealthTech Platform (Q2 2026) is the benchmark for regulated-sector certification. CE marking under IEC 62304, ISO 27001 certification, and multi-year hospital contracts. Grade AA, 5.2x ARR — and a transaction structure that required zero renegotiation post-LOI.
