As answered by people managing JSONLint and Pingback.
Pingback's answer:
Built specifically for UK trade businesses, not adapted from a generic US tool. It automatically handles UK compliance most competitors leave to you — GDPR-compliant call recording retention, SMS consent (STOP/START), and full ICO registration. Its AI also trains on the business's own website and uploaded documents, and never sends anything automatically — a human always reviews and sends the reply.
Pingback's answer:
Pingback is priced and built for small UK trade businesses specifically, not enterprise teams — honest, capped-usage pricing rather than per-seat enterprise costs. It bundles missed-call text-back, a unified inbox, AI lead analysis, invoicing, and review requests in one place, so there's no need to stitch together several separate tools.
Pingback's answer:
UK trade businesses — plumbers, electricians, heating engineers, and similar small or solo operators who lose jobs to missed calls while they're out on site.
Pingback's answer:
Pingback was built after seeing how often small UK trade businesses lose real work simply because they couldn't get to the phone in time — most callers who don't get through just ring the next number on Google rather than leaving a voicemail. It's being built directly alongside real trade businesses in beta, shaping the product from actual feedback rather than guesswork.
Pingback's answer:
React and TypeScript on the frontend, Node.js/Express on the backend, Twilio for calls and SMS, Google Gemini for AI, and Stripe for billing.
