Yep, that’s what I do. I’m the marketing, product and design cofounder and I pair with a dev.
The last two companies I’ve sold have had this structure and it works well.
We collaborate on wireframes, I turn it into designs in Figma, he executes with code and I sell it.
We both get feedback, build it into the roadmap, then start the next process over. He builds, I sell.
You need production and distribution, it’s hard to make it work without both.
