I think that Alchemax could be a good corporation for Peter to show his intellectual abilities. I know he is currently at Horizon, but in this promo, he may be getting fired from Horizon (or he could just be kicked off of the Avengers, but I hope he gets fired, so Alchemax can be introduced).
In 2099, Alchemax is introduced way later in time. I think the the company should be introduced somehow, due to something "SpOck" does. I personally like the concept of Alchemax more than Horizon as well. Time and events have been changed in Marvel plenty of times, so why not make a slight change that somehow brings to the creation of Alchemax, years before it was originally founded? Alchemax could also be more up Peter's alley, if it was made into a biological company.
I also like the idea of Alchemax going head-to-head with Oscorp Industries , with Alchemax coming out as the victor. Then it going up against Stark Industries, similar to how it was in Edge of Time.
And for anyone still not convinced that Alchemax should be introduced earlier, watch this video.
