GRADE B
What their homepage claims
“Vendo · Your product, shaped to every customer”
What that means
They sell an open-source customization layer that lets users build their own features and micro-apps on top of your product.
Verdict
The page communicates a product idea but fails to state a concrete product noun in the main headline, though it provides numeric proof and clear CTAs. Overall, clarity is moderate with room to anchor the offering in concrete terms.
What to fix first
Ranked by what each change is worth on the composite — the gap to the next rung of the ladder times the dimension’s weight. Computed from the scores, not written by the model; the model’s sentence under each is the action.

Index’s suggestion
“Open-source customization layer to let users build features on your product”
Built only from facts already on the page — not the company’s words. Shown so the gap between what was written and what could have been written is concrete rather than a number.
