A platform built by SaaS founders, for SaaS founders.

Invincible Software Holdings (ISH) builds a portfolio of founder-led B2B SaaS companies, with a core focus on HR tech and fintech. Founded by SaaS entrepreneurs Michael Richards and Adam Reynolds in partnership with Strada Partners, ISH acquires businesses with €1–5m ARR and supports their transition from founder-driven to scalable organisations. We invested in ISH to apply an operator-led model where hands-on execution, not financial engineering, drives long-term value creation.
