As answered by people managing DevFinanceTools and TryHerd.app.
TryHerd.app's answer:
Most competitors focus on marketing attribution and charge $39-299/month. Herd focuses on the checkout experience, starts free, and never requires you to log in, the Monday digest comes to you.
TryHerd.app's answer:
Herd is newly launched and onboarding its first merchants.
TryHerd.app's answer:
Remix, Shopify App Remix, Supabase, Anthropic Claude API, Render, and Resend.
TryHerd.app's answer:
Every other post-purchase app hands you a dashboard. Herd reads every response and emails you a plain-English summary each Monday, what customers loved, what frustrated them, one thing to fix. No charts, no exporting.
TryHerd.app's answer:
Most merchants only learn something went wrong after a bad review. Herd puts a 15-second widget on the thank-you page and has AI read every response, so merchants hear about problems before customers go public.
TryHerd.app's answer:
Small to mid-sized Shopify merchants, often solo founders, in apparel, skincare, home goods, and handmade products who care about customer experience but don't have time for a survey dashboard.
