The problem

AI voice cloning is now accessible to scammers. They can sound exactly like your kid, your bank, or your doctor — using just 3 seconds of audio scraped from a social-media post. Traditional robocall blockers built for 2015's threat model can't stop a clone calling from a real number, sounding like a real person, asking for money in an emergency. Elderly parents are the highest-risk demographic, and existing solutions (Hiya, RoboKiller) are built for generic spam, not voice clones.

Approach

• Built a trust verification layer on top of the existing phone system — no app required from the parent, no behavioral change needed, just a 5-minute setup that protects invisibly.
• Created a free top-of-funnel scam database lookup tool (no signup required) where users paste unknown numbers for instant scam-report checking — optimized for the question caregivers Google most.
• Designed the dashboard for the adult child managing the account — not the elderly parent: call log, allowed / blocked counts, contact management.
• Implemented 3 pricing tiers: Free 14-day trial, $9/mo (One Parent), $29/mo (Multi-Family).
• Deployed across Next.js + Vercel (landing + dashboard), Supabase (auth + DB), Twilio (voice), Stripe (billing), Claude API (content + support automation), n8n (operational workflows), GA4 (analytics).
• Built end-to-end as solo founder: landing, dashboard, voice infrastructure, billing, paid ads, content stack, scam-database ops — all by one person to ship fast while AI scam losses grow 30%+ year-over-year.

Results

• Live in beta as of May 2026 with 3 pricing tiers and a 14-day free trial.
• Landing page live at checkthecaller.com with a clear value prop and product preview.
• Free scam-lookup tool deployed as inbound funnel — no signup friction.
• Full caregiver dashboard functional for account management.
• Demonstrated full solo-operator capability: every system layer built and operated by one person, no agency overhead.
