HelloBox
Multi-channel contact widget for websites.
What it does
Combines multiple contact channels into one floating widget. Detects mobile vs. desktop to open the correct WhatsApp app. Sends contact form emails reliably via the Postmark infrastructure. Displays live social proof notifications of recent visitor interactions. Provides a white-label dashboard for agencies to manage clients.
Why it works
Device Intelligence: It stops WhatsApp links from breaking by intelligently detecting whether to open WhatsApp Web on desktop or the native app on mobile. Frictionless Contact: Allows website visitors to start a conversation using the messaging app they already use daily, boosting engagement. Social Proof Built-in: Acts as a two-in-one tool by displaying recent conversation statistics as FOMO notifications to encourage trust. Agency Friendly: Designed heavily for B2B reselling, allowing freelancers to rebrand the widget, set their own prices, and manage all clients from one hub. Reliable Delivery: Bypasses standard, often-spam-filtered server emails by hardwiring form deliveries through Postmark.

Founder story
Paul Anderie noticed a massive shift in how small businesses communicated: customers didn't want to use clunky website live chats anymore; they just wanted to send a WhatsApp or Facebook message. However, embedding those links on websites often led to broken desktop experiences. In 2020, Paul built HelloBox to perfectly route these chats based on the user's device, turning it into a highly profitable white-label tool for web agencies globally.
