Miso.ai
Miso.ai (Miso Technologies) builds LLM-powered search, answers, and personalization for publishers, marketplaces, and content sites. Its flagship product, Miso Answers, sits on top of a customer's own content catalog to deliver ChatGPT-style, citation-backed answers with no hallucinations - fine-tuned to each brand's voice and grounded only in their material. Spun out of privacy-centric 'small data' research at Cornell Tech's Small Data Lab, Miso helps sites like O'Reilly Online Learning and Foundry's tech publications turn their archives into trustworthy answer engines that lift engagement and subscriptions.
Orama
Orama is an open-source search company building an 'answer engine' for developers - a lightweight, high-performance stack that bundles full-text, vector, and hybrid search with automatic embedding generation and built-in LLMs. Started as the open-source project Lyra and incorporated as OramaSearch Inc. in 2023 by Issac Roth and Michele Riva, its core library ships in under 2KB and runs in the browser, on servers, or at the edge. Orama powers site search and AI answers for developer platforms including nodejs.org, tanstack.com, and solidjs.org, and its OramaCore runtime packages a search engine, vector database, and LLM interface into one deployable unit.
serviceMob
serviceMob is an Irvine, California enterprise software company that calls itself the Answer Engine for Customer Service and Support. Born as an academic project at MIT, it unifies the scattered 'dark data' of the service journey - CRM, contact center, workforce management, and ticketing systems - into a single behavioral data ontology it calls Ontolytics. Instead of reporting traditional KPIs like average handle time and CSAT, the platform models each customer experience as structured data to find and prevent the root causes of repeat contacts. Delivered by embedded Forward Deployed Engineers, serviceMob says it has driven more than $75M in client savings and eliminated hundreds of thousands of repeat contacts.
Perplexity AI
Perplexity AI is a San Francisco-based AI company that built the world's leading 'answer engine' ? replacing traditional link-based search with real-time, AI-generated responses that cite their sources. Founded in August 2022 by four AI researchers from OpenAI, Meta, Databricks, and Quora, Perplexity has grown from a scrappy post-ChatGPT prototype to a $20B+ company with 45 million monthly active users, over $1.7B in total funding, and a product suite spanning a conversational search engine, a developer API platform, and the Comet AI browser.
