WinSystem of Action — Part 1: Hero Users
In vertical SaaS, the next battleground is the System of Action — where AI doesn’t just help run the business, it does the work. The winner gets the user, the workflow, and the economics.

“AI is eating software” is a narrative that moves $100Bs of private investment and huge swings in the public SaaS market.
We've been on a journey to understand the impact of AI on vertical SaaS for the past three years (2023, 2024). In particular, we wanted to know how Control Point incumbents would compete with Native AI challengers. We now have an answer: the battle will be won by a race to become the System of Action.
A System of Action is the next step beyond the System of Record, where humans, AI-assisted humans, and fully autonomous AI agents are able to act on data and trigger downstream workflows. In doing so, they subsume the Control Point and gain the high ground.
At Tidemark, we try to open-source our thinking as much as possible to help founders win; however, as investors, we can’t give everything away in public. If you’re an operator or founder, you can request access to the rest of this piece below.
