## What is Yuma AI? Yuma is automating customer support by providing an AI Support Agent orchestration platform. Yuma provides autonomous AI agents dedicated to customer service and e-commerce. We integrate directly with help desk software (Zendesk, Kustomer, Gorgias, etc.) and focus on helping large Shopify brands deal with their high volume of support requests. Top merchants using Yuma can automate up to 80% of their support tickets fully autonomously. ## Why do Shopify merchants need Yuma? There are thousands of large Shopify merchants around the world generating $10M+ a year. Most of them have taken over some niches and are great at what they do: selling their products. But they all have one thing in common: they all hate customer support. It's a burden for them and a huge source of cost, as they receive hundreds of requests per day. Some of them have dozens of support agents on staff, usually offshore, and the overall quality is still often pretty poor while staff turnover remains high. Those merchants have been promised automation for years but have always been disappointed by the outcome. As customers, we have all had to live through a terrible support automation experience before, so this is no secret, and everyone knows that the current state of the technology is quite bad. ## Yuma is solving this in a few ways: Yuma isn't just another RAG chatbot. Our platform provides autonomous AI agents dedicated to support and ecommerce. These agents are powered by knowledge, follow processes, and are managed by our in-house AI orchestration technology. This ensures safety, control, and quality at every step. We believe that to truly automate customer support, we must develop a platform that mimics the actions of a human support agent. That's exactly what we've been doing. Currently, our top merchants are automating 60% of their support tickets through Yuma. Yuma can fetch information from external services and take actions in other apps as needed to resolve each ticket. We are laser-focused on building the best AI support agent platform and aim to achieve 80% true automation in the next few months. ## Fun Fact Yuma got started by accident. This is my third YC startup after Socialcam (W12) and Triplebyte (S15). I released Yuma as a prototype for fun in mid-December 2022 and was overwhelmed with demo requests. That's when I knew I was onto something and had to turn this into a real company, once again.

FlyCode helps subscription merchants maximize revenue. We reduce involuntary churn by managing payment failures intelligently. We’re Jake, Etai, and Tzachi and we’re building FlyCode. TL;DR: If you sell SaaS or B2C subscriptions, we’re here to help you recover lost revenue due to failed payments and involuntary churn. ‘Involuntary’ or ‘Passive’ churn is a hidden Revenue Killer 💳 for Subscription Businesses ❌ THE PROBLEM: Recovering Failed Payments is Complex Involuntary churn refers to the loss of subscribers due to payment failures, not due to them actively canceling. While it is both possible and a worthwhile strategy to attempt to win back a customer during the cancellation process — involuntary churn is not intentional and in most cases, your customers aren’t even aware that their payment failed. 💰 Bottom line? Effective payment optimization does reduce involuntary churn and will increase ARR by as much as 5-10% FLYCODE SOLUTION 💡 FlyCode leverages ML and AI to provide Payment Optimization and smart payment retries to maximize subscription revenue and reduce churn. We apply a unique model tailored to each Merchant and their customers to ensure optimal results. ⚡️Automatically recover failed subscription payments and reduce passive churn ⚡️Use ML & AI based payment optimization to find the best time to charge your customers ⚡️ Improve customer experience by coordinating payment retries with customer emails/SMS 🛠️ We support OOTB + Custom Integrations for Merchants and White-Label for Platforms

Navigating chronic illness is an isolating and lonely process which ultimately reduces medical adherence and adversely impacts outcomes. There are over 100 deadly chronic conditions as 1 out of 2 Americans is currently living with at least 1 chronic condition. The US healthcare system has over $1 trillion dollars in direct costs. Medical adherence rates for therapeutic programs and medicine are only 50% because patients feel lonely, isolated, and unsupported in their chronic illness journey. Reviving Mind is an in-network telehealth provider that improves clinical outcomes and program adherence for the senior medicare and medicare-advantage population that is plagued with loneliness and chronic illness. This is done through a novel and proprietary clinical program and technology platform that integrates virtual, private, curated, and professionally led groups that scale up to 8-patients with individualized and goal oriented lifestyle medicine coaching that is automated but managed by a licensed provider. Scaling rapidly across the United States.
