Customer Support Startups funded by Y Combinator (YC) 2026

Dialogus builds self-improving AI voice agents for enterprise operations. Our agents handle high-volume workflows across customer support, sales, collections, and other operational functions, integrating directly with the systems enterprises already use. Our agents continuously learn from real conversations and business outcomes: identifying where interactions fail, proposing improvements, testing those changes across thousands of simulated conversations, and deploying better versions with human oversight. The result is AI that doesn’t just automate calls, it gets better at doing the job over time.

Clad turns Slack, Teams, and email into one organized support queue. Agents investigate and resolve hard tickets the way a dedicated hire would, and every resolved conversation becomes knowledge, written up automatically.

Prox turns product expertise into revenue for equipment manufacturers. Equipment buyers rarely begin with a model number. They begin with a job, an installed system, a constraint, or a problem. The knowledge needed to qualify, recommend, configure, quote, repair, replace, or upgrade the product is scattered across manuals, catalogs, spreadsheets, calculators, product managers, applications engineers, dealer processes, support teams, and legacy systems. The result is abandoned demand, slow qualification, wrong-fit recommendations, quote delays, weak dealer follow-up, missed parts and service revenue, and dependence on a few experienced people. Prox builds AI product specialists for equipment manufacturers. A product specialist uses the manufacturer's approved product knowledge, expert rules, calculators, and connected systems to move customers and frontline teams from a complex product question to the right purchase, quote, dealer, parts, service, replacement, or upgrade path. How it works: 1. Understand what the person is trying to accomplish. 2. Resolve the product, application, and operating context already available. 3. Ask only for the missing information that changes the result. 4. Apply approved sources, expert rules, and deterministic tools (calculators, selectors, configurators, comparisons). 5. Produce a supported, cited recommendation, configuration, procedure, or decision artifact. 6. Move the person into the correct cart, quote, RFQ, BOM, dealer, sales, parts, service, replacement, upgrade, or expert action with the context preserved. One product specialist, many governed skills: product discovery and comparison, sizing and configuration, competitive defense, quote preparation, dealer enablement, installation and commissioning, troubleshooting, parts identification, and approved service, replacement, and upgrade paths. Manufacturers deploy those skills to customers, dealers, sales teams, applications engineers, support teams, or field service. Existing CRM, CPQ, commerce, and support systems stay in place. Support and service are revenue-bearing surfaces. The specialist resolves the customer's problem first, then surfaces the approved part, service, replacement, or upgrade path only when the evidence supports it.

Clarm Atlas 10xes productivity for non-technical operators in high-trust, regulated teams - banks, healthcare, insurance, publicly listed companies - by letting them build their own, fully governed AI agents. Teams build agents on their own approved data: every answer cites its source, all primitives are deterministic and highly governable, every action is logged for audit, and you bring your own AI model.

We run customer operations for regulated industries with AI. Our QA layer reviews every interaction, human and AI, cutting manual QA by 99%. On top of it sit specialist agents for onboarding, remediation, reactivation, and retention that own accounts from approved to transacting, chasing customers over WhatsApp, email, and SMS

Enterprises have millions of customer interactions every year but are only able to monitor less than 2-5% of those. The rest 95% is unmonitored risk across compliance, customer experience, product defects, and agent performance. With AI agents widely deployed across customer support organisations this problem increases exponentially. Every company needs a unified layer that allows them to monitor and govern all customer interactions with customer support teams, humans and AI. Intryc is building this layer.

Build and run an AI support agent that resolves even your most complex tickets end-to-end. If a tool has an API, you can securely connect it to your agent - just by chatting with Parahelp. For example, you can connect Stripe so your agent can resolve billing questions and refund requests.

## 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.
