Parental Consent Flow Builder

3.30

Derivation Chain

Step 1 OS-level age verification mandate
→
Step 2 Mandatory parental consent for minor service usage

Problem

The number of apps requiring parental consent for users identified as minors after age verification is surging, but building a parental consent flow in-house (identity verification → consent form → signature → confirmation) takes 3–4 weeks of backend development plus 2 weeks for identity verification API integration. In Korea specifically, legal guardian consent requires mobile identity verification (e.g., PASS), adding significant implementation complexity.

Solution

Provides parental consent flows as an API/SDK that can be integrated into apps with just 3 lines of code. Supports multiple consent methods including Korean identity verification (PASS/joint certificate), email verification, and SMS verification, with automatic legally compliant archival of consent records.

Target: Backend developers at Korean EdTech/gaming startups with 5–20 employees operating services that include minor users
Revenue Model: API usage-based: 300 KRW (~$0.22) per consent transaction, minimum 30,000 KRW (~$22)/month. Volume discount to 150 KRW (~$0.11) per transaction above 10K/month
Ecosystem Role: Infrastructure
MVP Estimate: 2_weeks
