Top Tech Startups in United States in 2027

Promethist is a deep-tech company building the next generation of enterprise conversational AI. We combine conversational AI with psychological and behavioral expertise to create Relational agents that enterprises deploy in production, at scale, to enhance performance, and engagement across customer service, HR, employee care, education, and beyond. Our technology is live inside large enterprises, including a leading European bank scaling a deployment from hundreds to thousands of seats. We care about human-centric design, real outcomes, and being a voice worth listening to in the AI conversation, not another vendor adding to the hype.

Convertly is an AI growth team for Shopify brands. It runs your entire creator and ambassador program end to end — and you just approve. Every brand knows creators drive sales, but almost none can afford the headcount to run a real program. Convertly replaces that headcount with six AI agents. They discover and recruit creators from four sources — your own customers, social search across Instagram/TikTok/YouTube, an opt-in creator network, and your apply page — then run campaigns, manage content and UGC, give every creator a shoppable storefront, attribute every sale back to Shopify, and handle commissions and payouts. A human sets the intent and approves; the AI does the work. The moat isn't the model — that's commoditized. It's the closed loop: from an AI decision to real, attributed Shopify revenue, plus a trust layer that moves money safely and only raises autonomy where measured outcomes justify it. We're already live on production. The full loop — recruit a creator, attribute the sale, pay the commission, show the brand the revenue it created — runs today. Now we're onboarding our first Shopify brands and building the category. Stack: TypeScript, Next.js, NestJS, Prisma/PostgreSQL, and Claude, shipped as a public Shopify app. If you want to build an AI-native product that moves real money for real merchants — and help own a category while it's still early — let's talk.
