- 0:15 Okay, so welcome everybody.
- 0:17 Hi, my name is Christopher Lovejoy, and I'm gonna talk about how to leverage domain expertise to build better AI products.
- 0:26 And the way I believe you can do this is by building what I call a domain-native AI organization.
- 0:31 So I'm gonna talk about what that looks like.
- 0:34 A brief background about me, because this is relevant.
- 0:37 So I started out my career as a medical doctor.
- 0:39 I trained in the University of Cambridge and then worked in the NHS for several years.
- 0:44 And I then, in 2018, moved into AI space, training and building models, and working in various organizations, including Tandem, which is the largest AI product provider in the UK in terms of adoption.
- 0:59 Also Anterior, I was the first employee and it's a square back startup forming prior authorization in the US and then also various other startups as well.
- 1:11 And my kind of challenge at all of these different companies was we're building some kind of product that bakes in domain expertise.
- 1:19 How can you do that?
- 1:21 How can you leverage that in a way that then builds a differentiated AI product?
- 1:30 So I talked a bit about this at the last AI engineer conference in San Francisco.
- 1:34 I shared my thesis, which is that the system for incorporating domain insights is more important than the sophistication of your models, of your pipelines.
- 1:43 I talked about the last mile problem, which is this challenge of getting your product to really understand the specific nuances of the workflows of the use cases of your customer that you're serving.
- 1:55 And this talk was,
- 1:57 seen by a lot of people, about 100,000 people saw this across different platforms.
- 2:02 Many of them reached out to me, and the kind of most common question that they had was, okay, but how do I build my organization?
- 2:09 Like, I'm kind of on board.
- 2:10 I get that domain expertise is important, but how do I build my organization to actually enable this to, like, what kind of domain expertise should I hire?
- 2:18 Where should I put them in my organization to enable this to take place?
- 2:20 So that's what I'm gonna talk about today.
- 2:24 And I've heard people say that winning in vertical AI, you kind of want to get the best model.
- 2:30 And actually, I don't think this is true.
- 2:31 I think that fundamentally, winning in vertical AI is an organizational problem.
- 2:44 So I have this framework based on different organizations I've seen and worked at and how they're baking domain expertise.
- 2:53 which is that you can do it in three main ways.
- 2:55 You can have your domain expert as an oracle, as an evaluator, as an architect, and I'm gonna talk a bit more about those in more detail.
- 3:04 But just stepping back, why do we care about vertical AI?
- 3:08 Ultimately, it comes down to the fact that vertical AI is a big opportunity.
- 3:11 So a lot of VCs are talking about, you know, this is the next big thing, as a lot of startups raising big amounts of money on this potential, this promise.
- 3:20 And as Bessma pointed out, vertical AI, you know, we had vertical SaaS, and that was a 50 billion or something dollar market.
- 3:26 But actually, now AI is moving into the kind of labor force.
- 3:29 And that's like a multi trillion dollar market.
- 3:33 but we've not yet really seen success at scale.
- 3:37 And according to Gartner, about 50% of all generative AI projects were abandoned last year.
- 3:42 And I think there's many reasons for this, but my take is that one of the core reasons for this is that we're often building AI products and AI systems without really having a deep kind of understanding of exactly what workflows we're automating and exactly how the domain experts would perform these kind of processes.
- 4:04 So just to reiterate, my belief is front-end models are good enough, but the gap is now how do organizations operationalize the expert judgment around them?
- 4:11 And the three most common mistakes that I have seen are, firstly, not hiring domain experts, or hiring them too late, secondly, hiring the wrong kind of domain experts, and then finally, not fitting them into your organization appropriately, not leveraging them correctly.
- 4:25 And so this maps to three questions, which I'm gonna address in this talk, which is, do you really need a domain expert?
- 4:31 What's the why?
- 4:33 If so, who do you need?
- 4:34 And then, how do you leverage them?
- 4:36 So I touched on the first one, and then this Oracle evaluator architect framework I'm gonna go through answers those second two.
- 4:43 So, do you really need a domain expert?
- 4:46 My take is that the answer is yes, and it's because
- 4:51 Appraising AI quality is something that's very important to do in your company.
- 4:55 You want to be able to make decisions between different approaches based on the kind of output that they give.
- 5:00 And your company needs to have a sense of what good AI quality looks like.
- 5:04 And that ultimately requires judgment.
