Reflection is a research lab making intelligence open and accessible for everyone to use, customize, and build on. Our team previously built frontier LLMs at labs like DeepMind, OpenAI, and Anthropic. We believe AI should be built in the open, with transparent research and collaborative development. That means giving enterprises, governments, and sovereign entities true ownership and control of AI that performs at the highest level. Our mission: make intelligence open and accessible to all.

rift is a sales platform that helps salespeople focus on what they do best – selling.
On rift, you can accomplish everything you have to do to close deals - send emails, run sequences, cold call, and book meetings.
The difference is that rift automates everything in between. If your data is a bit messy - we’ll clean it for you. If it takes a long time to figure out who to reach out to - our platform will flag the most likely leads to engage. If your emails are landing in spam - rift will set up the infrastructure to make sure that you’re not landing in spam because of incorrect setup.
Sales teams today spend 70% of their time not selling. rift’s mission is to give that time back to them so they can focus on selling again.
You need to do two things to effectively sell over email:
1. Set up your cold email infrastructure correctly.
2. Send relevant sales emails to the right people.
rift does it all for you in a single platform. You don’t need to be an expert in email deliverability or cold outbound.
Our product implements the email infrastructure for you, so you can focus only on growing your business. We will work with you 1:1 on writing sales emails that actually get replies.

Tavus is a research lab pioneering human computing.
We’re building AI humans: a new interface that closes the gap between us and machines, free from the friction of today’s systems. Our real-time human simulation models let machines see, hear, respond, and even look real, enabling meaningful face-to-face conversations with people.
AI Humans connect and act with precision and empathy, making them capable, trusted agents. It’s the best of both worlds: the emotional intelligence of humans, with the reach and reliability of machines. They’re available 24/7, in every language, on our terms.
Imagine a therapist that anyone can afford. A personal trainer that adapts to your schedule. A fleet of medical assistants that can give every patient the attention they need.
Tavus: teaching machines how to be human.
