Airtrain AI

Airtrain AI is a no-code data platform for Large Language Models. Proprietary AI models such as GPT-4 are very powerful but also very costly, slow, unreliable, and unsecured. As businesses look to scale their AI prototypes into production-grade products, they struggle with large AI bills, slow APIs and large failure rates. On the other hand, smaller language models have been proven to be able to perform on-part with large ones with fine-tuned on high-quality datasets. Airtrain AI lets AI practit

Tekton Dynamics

match 80

Our mission is to empower every manufacturer, no matter their scale, to invent and build anything using intelligent robots. Today’s industrial robots are fast but "blind". They struggle with any task that isn't perfectly repetitive. We are building the eyes and brain (a proprietary vision system and AI model) that allow industrial robots to see, reason, and perform complex work with sub-millimeter accuracy and the adaptability of a human expert. We are witnessing the start of a new industrial re

Quickchat AI

match 66

Quickchat AI empowers companies to build their own Multilingual AI Assistants powered by generative AI models such as GPT. Thanks to our powerful integrations and API they can add the power of conversational AI to any website, product, app, game or smart device. Backed by Y Combinator and other notable investors.

Phonely

match 65

Phonely uses existing call recordings to create a 'AI vocal twin' that can answer customer support calls and match or outperform call center agents. On top of that we've built a Zapier like workflow that lets businesses connect to software or transfer calls just like a person would. Our platform sits on proprietary deterministic LLM that is both cheaper and more accurate than gpt-4o for call center inquiries.
