The Problem: For decades, the relationship between homeowners and door-to-door salespeople has been strained. Homeowners feel harassed by interruptions, and salespeople face constant rejection, trying to find interested homeowners. “No Solicitors” signs get ignored, and before you know it, everyone’s angry. The result is a lack of trust that hurts everyone, keeps great services and deals from homeowners, and happy customers from salespeople. The NeverKnock Solution: Meet NeverKnock and the all-new IntroSign - the system that bridges the gap between digital privacy and front-porch opportunity. Great sales is simply great service. Our mission is to remove the anxiety from the sales process by ensuring that conversations only happen when they are welcome. We bridge the gap using our patent-pending IntroSign technology. How It Works Set Your Terms: As a homeowner, you use the NeverKnock app to set your preferences. Are you looking for solar? Pest control? Or simply want a better deal? Place the IntroSign: Place your sign at your door and control your status instantly from your phone. Whether you’re working from home, putting the kids to bed, or looking for a solar quote, your sign lets sales professionals know your interests without being interrupted by knocks. The Digital Knock: When a salesperson arrives, they scan the IntroSign located at your door. Instant Filtering: The app instantly tells the salesperson if their offer matches your current needs. Respectful Contact: If there is a match, the salesperson sends a digital message rather than ringing the doorbell. You review the offer at your convenience and decide whether you would like to continue the conversation. Our Guarantee: We are creating a world where salespeople are rewarded for helping, not harassing. With NeverKnock, you get the service you want, without the interruptions you hate. Stop the knocks, not the deals. For Sales Pros: Stop guessing! The IntroSign gives you the immediate signal you need. Know which home services a homeowner has and if they're open to chatting. Send them a message about your offer through the app, and if they're interested, they’ll let you know. Respect the home. Empower the hustle Our Guarantee: We are creating a world where salespeople are rewarded for helping, not harassing. With NeverKnock, you get the service you want, without the interruptions you hate. Stop the knocks, not the deals.
