ActivityHero is an online marketplace connecting families with kids' camps, classes, and enrichment activities — a one-stop shop to find top-rated summer camps, holiday camps, and after-school classes near you across categories like art, science, sports, dance, and online programs. For activity providers it offers marketing and registration software (MarketingHero and custom registration software) plus programs for school districts. ActivityHero's developer surface is a provider integration built on outbound, HMAC-SHA256 signed JSON webhooks (a Registration API and a Schedule API) rather than a public REST API; it was surfaced as a portfolio company of 500 Global and enriched into the API Evangelist network from its published help-center docs.
