Sell one API that manages a product's notifications across email, text, and push, with templates, user preferences, batching, and delivery logic developers hate rebuilding.

The opening

Why this idea is overlooked

Every software product rebuilds the same notification plumbing (preferences, digests, quiet hours, retries across channels), and the existing orchestration players chase enterprises; a focused version for one vertical's compliance and workflow needs, like patient reminders or tenant notices, is a real wedge for a small team.

The roadmap

How to start, step by step

1
Wedge on a vertical, not on scale
Competing with the big messaging platforms on raw delivery is hopeless; they are your plumbing, not your rival. The wedge is the orchestration and compliance layer for one vertical: healthcare reminders, property management notices, or logistics alerts, each with rules generic tools ignore.
2
Validate with five product teams
Ask five teams in your vertical how notifications work in their codebase today. You are listening for the shame: hand-rolled preference tables, duplicated templates, missed quiet-hours rules. That shame is the product spec.
3
Learn the messaging regulations cold
Text messaging consent rules, sender registration, healthcare privacy constraints, and unsubscribe requirements vary by channel and industry. Baking compliance into the API is exactly why a vertical player beats the generic one.
4
Ship the smallest orchestration core
Templates, user preferences, channel fallback, and a send log, built on top of established delivery providers. AI tools speed the build and the endless template tooling; your quality bar is that a developer replaces their in-house mess in a day.
5
Price on monthly tiers plus volume
Common models are $50 to $500 per month by notification volume and feature depth, with a free developer tier. You are charging for saved engineering months, so anchor pricing against a developer's salary, not against per-message costs.
6
Earn trust with boring reliability
Notifications are the nervous system of the products that adopt you, so retries, idempotency, observability, and a public status page are the product. First customers arrive slowly through integration tutorials and marketplace listings, then stay for years.
