Transcript of this segment

it'll draft communication for you to send to those folks over email, LinkedIn, uh, phone, whatever it is. So, it'll sort of keep proactively building out your pipeline. And then last, I would say uh this is maybe the most nonCRM thing. It'll keep your entire company informed and what your customers want, need, and are willing to buy. So, you always have tighter alignment across product and engineering. >> So, lightfield.app is going to tell me what I'm doing right. It's going to tell me which customers I've forgotten about, and that everybody on the team doesn't have to be a slave to the CRM filling in all these fields. Go ahead and check out lightfill.app. Okay. So, now you have to ask yourself, um, who were the original backers? Who >> Oh, I've looked this up. >> The original backers >> I've I've looked this up >> of Harvey and who were their original uh Frontier Model providers? Who were who were Harvey's original backers? >> I'm I'm looking at this on Harmonic.ai. Thanks to our friends at harmonic.ai AI for allowing me to so quickly pull that up. Uh, a $200 million uh, investment. Oh, that's that's that's March. Yeah, March 25th, 2026. 200 million at 11 billion valuation co-led by GIC and Sequoia Capital with A16Z Coviction. >> Go backwards. Elon Gil back. Oh, okay. Who are who are we? >> Early rounds is where we want to go to that. See, this is what Harmonic's going to help us with. If you start getting >> our earliest backers, >> original capital and original models both ran through this company. >> Open AI was the day one believer. They led the $5 million seed round and also gave the founders early access to GPT4, which was a massive head start in building legal specific fine-tuning before anyone else had the model. There you go, Jason. Thanks, Harmonic. >> Thank you, Harmonic. Yes. >> Thank you, Harmonic AI. There you go. >> $5 million. First investment. >> Yes. >> One of the Open AAI startup funds first four investments. >> Yeah. They led the seed round. >> They led the seed round. Now, here we are. >> It was the OpenAI Startup Fund. Uh other early backers included Jeff Dean, head of Google AI by the way. >> Okay. Now, let's just pause here, put the two stories together. Sarah Frier, CFO of Open AI, says, "Hey, we hear you loud and clear." Harvey saying, "Hey, by the way, um, just want to let everybody know six months ago, we started using these open source models. We started building our own and we're building our own for our clients so that our clients don't share the intelligence. So if you're a litigation firm A and your top competitor litigation firm B, so Acme litigators and Delta litigators are both using Harvey. Let's say Harvey now is like, not only do we not trust Open AI with this, we need to have our own model. We need to build a fortress. We're gonna and we'll have our castle. It's gonna have a big wall around it. We're going to build two keeps. One keep for Acme litigators, one keep for Delta litigators. So y'all are going to get your own litigation data, all your internal memos, all your emails, all of your Zoom calls about this. We'll feed your local model for you, but it's not going to make it to our castle. You're in your own keep. Defend your keep. And the two keeps will not share data. >> Right? >> This is what's going to happen to the frontier models when they go public. You're going to have this headwind of which of these customers Harvey was probably spending, if I had to guess, I'm going to say 10 million a month with OpenAI.
