Boom AI
Boom AI is a San Francisco-based Y Combinator (F25) startup building an AI workforce that talks to a company's customers across SMS, email, WhatsApp, Instagram, and phone, learns what they need, and acts on it - collecting overdue payments, winning back churned users, driving sales, and onboarding people. Founded in 2025 by the team that built Atrato (YC W21), it aims to deliver the output of a full customer team without the headcount.
Cozmo AI
Cozmo AI (formerly CozmoX AI) builds multimodal 'AI employees' that answer calls, read documents, and complete regulated business processes end to end for financial services, insurance, and enterprise operations. Founded by Alok Kumar and Nuha Hashem - the team behind the Gen Z neobank Zywa - the Y Combinator W22 company runs from San Francisco and Dubai, and says its agents handle voice conversations in 70+ languages including multiple Arabic dialects.
Mundo AI
Mundo AI (YC W25) builds high-quality multilingual training data for AI models, tackling the shortage of non-English data that leaves most of the world's languages underserved by today's models. The company partners with native speakers and runs end-to-end operations in the countries where target languages are spoken, using proprietary software for data collection, generation, annotation, and quality assurance. Founded in 2024 by four University of British Columbia alumni, its customers are AI labs and companies training or improving non-English and multimodal models.

WIZ.AI is a Singapore-based enterprise voice AI company that builds generative-AI voice agents ("Talkbots") able to hold natural, human-like phone and messaging conversations in local Southeast Asian languages and accents - including Singlish, Bahasa Indonesia, Tagalog, Thai and Mandarin. Founded in 2019, it helps banks, telcos, insurers and other large enterprises automate customer service, collections, telemarketing and reminders across voice, chat and messaging channels, positioning itself as a local-first alternative to global contact-center automation vendors.
Sensay
Sensay builds lifelike AI 'digital replicas' that capture a person's or organization's voice, style and knowledge, then deploy that persona as a chatbot, support agent, tutor or companion. Founded by philosopher-turned-entrepreneur Dan Thomson in 2023, the company started with dementia and memory-care use cases - giving families a way to preserve a loved one's stories - and has grown into a broader knowledge-capture platform spanning enterprise offboarding, customer support, education and community management. Sensay pairs its AI engine with the $SNSY crypto token and pitches itself as a route toward 'digital immortality.'
