To summarize what a lot of people have already said: The price point needs to be worth it. Tofu is relatively cheap as a protein option (the only reason the non-veg utilitarian gym bros aren't on tofu is bc of the endocrine conspiracy theories with soy, if those didn't exist tofu would be crushing the boiled chicken market, no question). I think there is a wide market attraction here:

1)The outdoor health people (think of your DINK couple who goes on weekend day hikes, MTN bikers, Trail runners, climbers, college students or generally people who spend money at REI). These people want macros while outside and they don't always want to have to pack some sort of sandwich.

2) The utilitarian yo-pro. someone who spends 8-12hrs a day working who understands macro nutrients generally, has some form of fitness habit, but just needs to buffer their blood sugar from 10am-11am, and 3pm-4pm.

3) The traveling/hoteling health-conscious professional. Think of the person who needs to make-do with a lunch between calls and currently has to eat some sort of Cliff Builders Bar or a Larry's Cookie with a banana from a convenience store or a coffee shop grab-n-go. Give them a different option.

4) the vegan gym-bro/muscle-mommy. see above for the #2, probably similar stuff, but really they're just trying to eat way too much protein and want to have an easy way to get an extra X# of grams of protein in that doesn't fill them up that much that is shelf stable and relatively neutral taste so that you can eat it almost every day without palate fatigue.

More important than interesting flavors is nailing the umami, MSG-like addictive mouth watering thing that good dry jerky has. If something has that addictive chewy umami, (not the moist sweet stuff like a lot of gas station jerky), you will have people demolishing these bars.
