For anyone who doesn't believe that Bolt Threads (KBLBs main competitor) hasn't pivoted away from spider silk, and is now fully focused on mushroom leather, check out their instagram post from June 20th.

These days the scientists at Bolt are steadily inspired by fungi, but we’ll never stop being in awe of spiders. Our debut biomaterial, Microsilk™, was inspired by the proteins that make up their ingenious webs. By harnessing the power of bioengineering, we developed a process produce the protein in large quantities through fermentation, using yeast, sugar, and water. Visit the link in bio to learn more.

Someone's response:
This available yet?

Bolts response to their question:

Our sustainable alternative to leather made from mycelium, Mylo™ is closer to commercial readiness and so it’s become our top priority. As of right now, we are not selling Microsilk commercially and we are not taking on any new development partners. But you never know what the future may hold! ??

Plus, Every Job req on their website having to do with R&D/Production mentions experience with mycelium. There hasn't been a job req that requires protein fermentation in the last year from what I've seen.

This is the same tech that Spiber and amsilk uses. Our "competitors" will never make commercially feasible spider silk. Unfortunately, they are just now coming to that realization.
