Redapto
Redapto is a San Francisco enterprise-AI company (Y Combinator Fall 2025) building self-improving systems for customer support teams. Its platform monitors 100% of customer conversations across chat, voice, and email, catches quality issues and AI hallucinations in real time, runs custom evaluations tied to a brand's voice and policies, and automatically turns what it learns into updated training material and knowledge-base fixes. The goal is to move support from a cost center to a growth lever - lifting CSAT and net revenue retention and surfacing churn risks and expansion moments across the customer lifecycle.
Rowboat
Rowboat (YC S24) is a San Francisco and Bengaluru startup building open-source AI agent software. It began as a pre-trained customer-support LLM agent, grew into a widely starred open-source IDE for building multi-agent systems on the OpenAI Agents SDK, and is now 'your AI coworker, with memory' - a local-first desktop app that turns your emails, meetings, and notes into an editable knowledge graph so agents can actually get work done. Founded by the team behind Agara (acquired by Coinbase in 2021).
Syncly
Syncly is an AI platform built by a team that previously sold a machine-vision startup for $200M. It began as a customer-feedback analytics tool that ingests support conversations from Zendesk, Intercom, Gorgias, Slack, Front and Gong, then auto-tags them, scores sentiment, and surfaces the issues quietly driving churn - so CX and revenue teams can act before customers leave. The company has since expanded into AI social intelligence for the video era, adding tools to monitor TikTok, Reels and Shorts, discover creators, and unify voice-of-customer signals across channels.
Yuma AI
Yuma AI is an AI customer service platform for ecommerce brands, using autonomous AI agents to resolve support, sales, social, and chat conversations end to end. Built for large Shopify merchants and plugged into helpdesks like Gorgias, Zendesk, and Kustomer, Yuma automates the bulk of repetitive tickets - order status, returns, refunds, subscriptions - while keeping brand voice and guardrails intact. Founded in late 2022 by three-time YC founder Guillaume Luccisano, the company went through Y Combinator's W23 batch and raised a $5M seed round.
Implicit
Implicit (formerly Agolo, legally Ninoh, Inc.) is a New York-based AI company that turns a company's scattered manuals, SOPs, tickets and PDFs into a private 'knowledge engine.' Its KnowledgeOS platform builds enterprise knowledge graphs and AI Navigators that give support agents and customers expert-level, source-cited answers about complex products. The company pivoted from its original news-summarization roots into entity intelligence and product-expertise support, claiming roughly 3x the accuracy of generic LLMs with answers tied to a source to eliminate hallucinations.
Ema
Ema builds a 'Universal AI Employee' for the enterprise - autonomous AI agents that plug into existing systems and run business processes across customer support, sales, HR, finance, and compliance. Founded in 2023 by ex-Coinbase CPO Surojit Chatterjee and ex-Okta engineering VP Souvik Sen, the company is headquartered in San Francisco and has raised $61M to date.
