Signal Sources (v8 Triple Source)

Trigger

r/SaaS 솔로 파운더 AI travel planner — AI 버티컬 SaaS 개발 붐

Market

PromptLayer, Humanloop 등 프롬프트 관리 시장 → 회귀 테스트 특화 틈새

Workflow

AI 개발자가 프롬프트 수정 후 수동으로 10-20개 케이스 확인 → 누락·시간 소모

Problem

Developers building AI vertical SaaS (travel planners, legal AI, etc.) have no way to verify whether existing cases break every time they modify a prompt. They manage prompts with Git but cannot measure the impact of changes on output quality.

Solution

Register prompt versions → define golden test case sets → run automatic regression tests on prompt changes (LLM-as-judge) → report quality score changes. Integrates with CI/CD pipelines.

Target: AI vertical SaaS developers / solo founders and small AI teams (1-10 people)

Revenue Model: Monthly subscription $29/month (100 tests/month) to $79/month (1,000 tests, team & CI integration)
