Transcript context

…Yeah, I think it's kind of interesting to see the sketches that went into [inaudible 01:35:40]'s prototype, the Axion Orbital prototype that we just looked at, because they are super detailed. This is ... Doing this level of thought where you're pausing, you're being really intentional about what does the customer need to know, what needs to happen for them to find a solution to their problem and within the product, that's a way of doing your prompt engineering. If you end up vibe coding this prototype, but you start off with a very clear plan about this is what the thing needs to look like, rather than going immediately into a conversational mode where you're co-designing with the LLM and going back and forth via chat conversation, this is much likelier to yield an opinionated product that makes sense, that's very clearly defined around the problem that you're trying to solve, the tasks that need to happen to solve that problem, and the right messaging, the right wording. It's really crisply aligned with what you know about your customers, what you know about what they care about. That's such a good point. Again, just the concept of the primal mark is ringing in my head as you talk about this. Just as soon as you make that prototype, everything from that point is a response to that first idea, versus have I actually thought through what this should be. Guys, we did it. This is incredible. I think this is going to help a lot of people think through and actually save a lot of time. Is there anything else that you want to share, leave listeners with? Maybe a last nugget or something you want to, I don't know, just double down on to leave folks with before we wrap up. Well, one quick thing is that we've shared a lot of examples in this conversation. We actually have a template, a Miro template, that folks can use if they want to run their own foundation sprint. It's the template that we use when we're working with founders, taking them through these sprints. We do our work in Miro. Even if we're in person with them, we're usually working in Miro, or maybe working on paper and then capturing it in Miro because it's just such a great canvas to work on. We'll make that template available so anybody who's listening or watching can grab that and use it to run their own foundation sprint.…
