    CastleFlexx product lineup

    Loop's voice agents are recovering abandoned carts that our email flows never could have converted. The sales we're getting back are real and meaningful. The team is fantastic, executes changes fast, and has been a great partner. Highly recommend.

    Why voice wins

    Why voice works
    so well
    for CastleFlexx

    CastleFlexx sells to people in genuine pain. Back pain, plantar fasciitis, hip problems, tennis elbow — these aren't casual purchases. Customers have tried other things before. They've spent money on solutions that didn't work. By the time they reach checkout they're interested but cautious.

    That caution is what abandons the cart. Not price. Not distraction. They want to know — will this actually work for me specifically? Is this the right product for my condition? How long until I feel a difference? Those are not questions a product page can fully answer for someone dealing with chronic pain. A real conversation can. The AI agent asks about their specific condition, explains how CastleFlexx addresses it, and gives them the confidence to complete the purchase. That's the conversion — trust, not pressure.

    The biggest blockers

    The three objections
    costing CastleFlexx
    the most

    Across customer conversations, three objections came up again and again. The AI agent handled all three live on the call. Those same objections are now addressed proactively on the product page and in ad copy, improving conversion across the entire funnel.

    Will it actually work for my condition?

    Customers with chronic pain have been disappointed before. They need specific reassurance that CastleFlexx addresses their exact issue — back pain, plantar fasciitis, hip tightness, tennis elbow. The agent walks them through exactly how the product works for their specific condition.

    Which product is right for me?

    CastleFlexx has multiple products targeting different pain points. Customers weren't sure which one matched their specific issue. The agent asked the right questions, identified their primary condition, and recommended the right product with confidence.

    How long until I see results?

    Customers dealing with chronic pain want a realistic timeline. Vague answers lose the sale. The agent gave clear, honest expectations about when they'd start feeling a difference — which built enough trust to complete the purchase.

    Customer intelligence

    What CastleFlexx
    learned
    about their customers

    Before Loop, CastleFlexx had no way to hear what was going through a customer's mind when they hesitated at checkout. Now every call is recorded and summarized. Two discoveries changed how they market and position the product.

    Condition-specific messaging converts better

    Customers respond much more strongly to messaging that speaks directly to their specific pain point rather than general mobility language. "Back pain" converts differently to "tight calves." Those insights are now shaping ad targeting and landing page angles for each condition.

    Social proof around chronic conditions

    Customers dealing with long-term pain want to hear from people with the same condition who found relief — not general five-star reviews. The calls revealed that condition-specific testimonials are the most powerful trust signal for this audience. That insight is now driving how CastleFlexx collects and displays reviews.

    Customers turned partners

    From "Will this
    actually work?"
    to a scalable revenue system

    CastleFlexx started working with Loop because they wanted to convert more abandoned carts without adding headcount. What they got was a system that handles the hardest part of selling a pain relief product, convincing a skeptical customer that this time will be different.

    The AI agent has the same conversation a great sales rep would have. It listens to the customer's specific condition, addresses their exact concern, and gives them the confidence to invest in their recovery. That conversation happens automatically, within minutes of abandonment, 24 hours a day. Revenue they thought was lost is now a predictable line item. And every call recording is making the next conversation easier.
