Following the wind-down of QuantifyNinja, the platform’s seller toolkit and active user base have been transitioned to Juicer.Deals, which has assumed responsibility for the continued service of former QN users.
This is the official communication regarding the closure of QuantifyNinja and the assumption of its seller toolkit and user base by Juicer.Deals.
QuantifyNinja, after years of serving Amazon sellers, has been wound down. Maintaining the platform on aging infrastructure was no longer viable, and the depth of investment required to bring it forward — full SP-API rebuild, modern messaging compliance, AI integration — exceeded what could be sustained inside the existing product.
Rather than leave its users without continuity, the responsibility for QuantifyNinja’s seller community has been formally taken on by Juicer.Deals, an established Amazon-seller platform built on modern foundations.
If you held a QuantifyNinja account, a corresponding Juicer.Deals account has already been provisioned for you under the email address you used. The two capabilities QN sellers used most — Review Requests and Automated Messaging — have been rebuilt from the ground up inside Juicer.Deals: sharper, fully aligned with Amazon’s current policy framework, and integrated with the broader seller toolkit.
You will receive (or have already received) a direct email containing a sign-in link to your account. There is nothing to migrate, no password to set, and no historical data to re-enter. If you have not received the email, you can request one from the Juicer.Deals sign-in page.
Triggered by Amazon delivery confirmation. Per-product templates, language detection, full Amazon-policy alignment.
Per-template send rules with AI compliance review on every outgoing message.
Your account, registration date, and marketplace history have been preserved on Juicer.Deals.
A 30-minute call with the founder is included for former QN users who request it.
Former QuantifyNinja users are prioritized. We’ll walk through the platform together and answer questions before you commit to anything.

Sign in to Juicer.Deals →This is a transition of users and continuity of service, not a corporate acquisition. Juicer.Deals has voluntarily assumed responsibility for serving the former QuantifyNinja community by rebuilding the most-used tools and provisioning accounts for affected sellers.
No historical analytics, message history, or report archives transfer. The transition covers your account record (email, registration date, marketplace history) and access to the rebuilt tools. Going forward, Juicer.Deals will accumulate your data fresh from your Amazon SP-API connection.
No. The provisioned account simply makes the door easy to walk through. If you decide Juicer.Deals is not for you, you can ignore the email — no charges, no obligations. The platform offers a 7-day free trial before any commitment.
You can request a fresh sign-in link directly from the Juicer.Deals sign-in page. If your account does not appear, contact us via the Juicer.Deals contact page with the email address you used on QuantifyNinja.
No. QuantifyNinja’s authentication system is not active. Juicer.Deals uses its own sign-in flow, including secure single-use magic links so you do not need to set or remember a password.
Juicer.Deals offers a 7-day free trial with no payment required up front, and a clear pricing page is available after sign-in. No QuantifyNinja subscription has been carried over to a paid Juicer.Deals plan automatically — you choose your plan when you’re ready.
