>where do your advertising dollars go and how do you measure their success?
Sorry, but advertising spend is one of the few things I avoid sharing publicly. Most other things about my strategy, I think our execution is what makes the difference, so I don't care if competitors know. With advertising, it was expensive to figure out a successful strategy, and it's the kind of thing that a competitor can copy perfectly.
I can talk about measuring their success, though. The metric I focus on primarily is revenue on ad spend. Material costs make up about 33% of the revenue from TinyPilot's product sales, so if we get $1.50 for every $1 we spend on ads, we'd end up about breakeven ($1.50 from revenue - $1 for the ad - $0.50 for materials), so I aim to be at 2.25 ROAS or higher on any channel so we have a comfortable margin.
