Description

Subscription eCommerce brands and SaaS companies use Churn Buster's retention software to win back revenue from failed payments and keep customers who try to cancel. The two products run on their own or together. Dunning coordinates retries with branded email and SMS asking customers to update their payment details. Where Churn Buster handles the retries itself, it also sets their timing. With Cancel Flows, a customer who clicks cancel sees a short flow instead of a one click exit: a pause, skip, discount, or plan change, plus a question about why they're leaving. For regulated locations, Cancel Flows also includes a click-to-cancel option. Since 2013, Churn Buster has handled 50+ million failed payments, and its retention specialists have refined the default retry and campaign settings over 1,000+ accounts. Dunning connects to Stripe, Braintree, Recharge, Loop, Skio, Stay AI, Checkout Champ, Seal Subscriptions, Ordergroove, and more. Plans start at $269/mo on a flat fee set by MRR tier, month to month.

Description

ZenLLM serves as an AI-driven platform focused on optimizing costs for engineering teams that deploy LLM applications in live environments. By linking provider invoices to the underlying application activities, it identifies which specific prompts, workflows, models, customers, retries, and request paths contribute to financial expenditures. Teams can utilize the ZenLLM SDK to transmit request-level telemetry, allowing them to incorporate relevant business context—such as workflow, owner, customer, team, or product feature—without having to store the content of prompts or responses. In addition, it keeps track of token consumption, model selection, latency, errors, retries, and overall costs, revealing wasteful patterns that provider dashboards often obscure. The platform is capable of recognizing instances of context accumulation when conversations or agents repeatedly send extended histories, excessive use of premium models for low-risk tasks, retry loops that lead to unnecessary expenses, outdated system prompts, routing errors, anomalies, and a lack of accountability regarding costs. Furthermore, ZenLLM empowers teams to make informed decisions that can significantly enhance cost efficiency in their LLM application operations.
