SaaS Is Dead. Long Live SaaaS (Subagent as a Service)
The real shift isn't adding AI to software. It's software becoming AI. Nivedit Jain calls this SaaaS: Subagent as a Service.
Spec-Driven Development is an approach where software implementation starts from a clear, structured specification rather than vague ideas, scattered tickets, or incomplete conversations.
Latest thoughts on bridging the product-to-engineering gap.

OpenAI released GPT-5.4 mini and nano models, representing a strategic shift toward hierarchical AI architectures where large models orchestrate work delegated to smaller, faster alternatives.
A three-role system for AI-assisted software development: an architect who designs, a developer who implements, and independent reviewers who critique.
MySpec.dev is an AI spec-writing assistant that turns messy ideas into clear, structured requirements you can actually build from. It helps you define scope, user flows, acceptance criteria, and edge cases fast, so teams ship with less confusion, fewer reworks, and tighter alignment between product and engineering. We're currently in the product development phase, iterating fast with early users to ship a practical, spec-first AI workflow that helps teams move from concept to execution quickly.
From messy ideas to structured requirements in minutes.
Iterating fast to help teams ship with zero confusion.
