Create your entire 2026 product strategy in minutes.

Spine helps plan and validate your vision using real company data, market research, and AI councils — then turn decisions into PRDs, prototypes, and board‑ready artifacts.

Your business doesn't need more AI. They need validated clarity.

The pain isn’t speed — it’s unvalidated decisions and misalignment.

Strategy decks cost $5k–$10k+ and are outdated instantly
“What should we build next?” lives across Notion, Miro, & Slack
Teams manually copy‑paste the same question into multiple LLMs
Decisions feel confident — until blind spots surface after execution
Teams move fast, but not always in the same direction

Spine is where companies validate decisions — not just discuss them.

Spine is a strategy workspace that captures your company context and helps you:

Validate what to build before you build it
Pressure‑test decisions using multiple AI perspectives
Align teams around shared prototypes, not docs
Generate strategy, PRDs, prototypes, and decks from one source of truth

Grounded in Reality

Don't build on gut feel. Spine validates your strategy by combining market research, external signals, and your internal linear/docs context to catch risks early.
