Notable Moment

Arvid structures his prompts to generate explanations before numerical scores because language models predict one token at a time, making them justify predetermined numbers rather than reason toward accurate conclusions when scoring comes first.

Episode Transcript

Hey. It's Arvid, and this is the Bootstrap founder. This week, I wanna be as pragmatic as possible. Let's talk about not just AI this and AI that as I so often do, but the actual applications of generative AI that I personally leverage within PodScan to get my customers to see the value of the product and that as quickly as possible. You know, it took me a pretty long time to actually realize this, but using AI in a SaaS, that's not just something like a chatbot for my customers or something like that. AI can work behind the scenes quite effectively, and that facilitates getting the right stuff in front of the right people. And in just to figure out who people are and how I should talk to them is something that AI can help you with. Today, I wanna share exactly what I'm doing, how expensive that is to run at my scale and how I believe that this can be part of every single software as a service business out there. Even if you don't have any touch point with AI, with the concept of artificial intelligence in that business for those customers at all. Even if you don't think you should be offering AI features to your customers, there's a good use. And I'm gonna share with you how I'm using it behind the scenes. And speaking of scaling smarter, not just faster, that's exactly what today's sponsor, Paddle, is all about. They're running this exclusive five part online life series designed for SaaS and digital product leaders who wanna scale with precision. It goes, like, from pricing strategies to exit planning, and each of these sessions is packed with a lot of lot of actual data that they pull from their own database, improving strategies. So if you're serious about really putting more effort into growing a SaaS, check out paddle.com's event series, because just like the AI strategies that I'm about to share with you today, it's all about working smarter to create these magical moments for your customers. So go to paddle.com to check this out. Let me start with the internal use of generative AI that has been absolutely transformative for me and PodScan. Six hours after a customer signs up for that trial, exactly six hours after, something magical happens, or I coded it to actually happen, but they don't see it. It happens completely behind the scenes. I let them explore the platform first in those first six hours. But at that six hour mark, I start scoring them. Or rather, I have an LLM that is fed with a lot of information, scored that customer for me on a scale from zero to 10. So I take everything that I know about this person up until that point and have the AI come up with a number following a rather complicated prompt on how to score them. So here's what I collect for this. I collect …
