How SaaS Is Dying — and What’s Replacing It
This isn’t a trend. It’s a foundational shift.
Startups are moving from apps to agents — from dashboards to digital teammates. And this Manifesto is the clearest blueprint for what comes next.
What Is the Agentic Era?
In 2011, Marc Andreessen said that software was “eating the world.”
In 2025, AI agents are eating software.
Most SaaS companies still sell tools. Agentic startups deliver outcomes.
Instead of building static apps, today’s most innovative founders are deploying AI agents that act autonomously:
- They analyze.
- They decide.
- They execute.
This Manifesto breaks down the mental model and architecture behind this shift — from first principles to practical frameworks.
Inside This Deep Report
- Why SaaS is reaching its limits — and what replaces it.
- How to build startups around agents, not features.
- The shift from user workflows to business outcomes.
- Why the agentic stack demands new team structures and skills.
- Legal, ethical, and compliance fundamentals every agentic startup must know.
Why Founders Need This Now
Some founders are quietly experimenting with agents. Others are going all in. Many are stuck in the middle — still trying to retrofit SaaS logic into a world that’s already moved on.
What they all need is a framework. A way to think clearly about what to build, who to hire, and how to scale in an agent-native world.
At InTheValley, we see this daily:
- Startups hiring their first AI engineer.
- Teams are rethinking their roadmaps because Copilot has just eliminated half of their backlog.
- Founders wondering if they need to build an app — or a team of bots.
This Manifesto answers those questions.
It’s not a prediction. It’s a field manual.
