Count your models
A button says "View all 8 models", while the Astra section lists five models.
I'd make the number match the list, or show all eight. Precise people notice small mismatches.

Your validation section is unusually honest: blind pilots with sample sizes, Spearman ρ and a 2.30°C mean absolute error, rather than one big claim.
Below: the concept I built for you, and the six changes I'd make first. Most take days, not months.

The first three are the ones on your postcard. The rest come next.

The page says "Backed by wet-lab results". The FGF21 result is "Blind, n = 1" and the TNF-α pilot is n = 24.
I'd open with the GPCR study, 190 mutations across 7 receptors, and present the smaller pilots as early signals.
The headline reads "Fewer experiments. Higher hit rates." No number is attached to either promise.
I'd add one figure under it, such as the 78% correct direction from the GPCR study.
The header says "nebula" in lower case and the footer says "Nebula".
I'd pick one spelling for the product name and use it everywhere.
The homepage names no team members. The team only appears behind the About link.
I'd add a small founders strip on the homepage. Scientists buy from people as much as from models.
Compare, FAQ and Researcher Program appear only in the footer, while Atlas appears only in the header.
I'd align both menus, so every product and resource is easy to find from anywhere.
