Both of these markets have long lead times, tight HW build times, and move incredibly slowly. They are not the kind of markets that like using stuff from new companies with no history. Again, I'm no expert, but I'd say you need to be concentrating on sales and market research now.
Edit: I should note that if it weren't for Dusty and his docker image generating GitHub repo for Jetson, we would have spent weeks trying to get our kernels and optimized models shipped to customers.
1. Go deep on the tech, there are funders who will want equity stakes in risky startups because they operate in adjacent markets. It's often cheaper to invest 1MM on a startup than internal R&D activities. If it has promising results, those same investors may ramp up their spend or pivot to an acquisition strategy.
2. Get early customers, if you have 1-10 large enterprises with a committed spend - then you are likely golden. However as nice as this option sounds, there are few avenues to get this type of commitment. If you are in the fortunate position of knowing the exec/founding/investor team of a large LLM provider - it's possible. But easier said than done.
3. Build it and they will come, business strategies take time to develop - maybe that time is poorly spent. Build the best version of your product and someone might take it up. There are a few investors who will take a flyer on this type of founder mentality. Benefit to the investor is that they can get a much larger equity stake/board position in exchange for the early creative freedom. If it works out, the investor can get a lot of alpha. A card which handled LLM inference at 1/100th the cost of an H100 could produce quite a bit of value for the right buyer.
4. Do the technical work to get it a little bit beyond just an idea and then get acqui-hired by a large company who has the resources to push this.
So if I was them I would be doing thought experiments on how this technology could benefit a whole range of businesses e.g. gaming consoles, televisions etc. Not many people would've guessed LG acquiring Palm for example.
And this is long known - even Raspberry born for other market, fortunately, was not just killed but conversed to target enthusiast and even now incomplete project.
