## CTA — 62, Fair

We assess whether the primary call to action earns the click through its copy, size, verb, and cost-feel.

The assessed Stoa CTA is **“Sign up.”** The comparison includes Vast.ai’s **“Get Started”** email CTA and Shadeform’s **“Go to platform”** CTA.

### CTA problems identified

- The label is generic and gives no value promise.
- The click feels like signup work.
- The CTA does not echo the headline’s market hook.
- Its muted color gives it low visual prominence in the hero.

### CTA ranking

2. Shadeform — 68
3. Stoa — 62

## Value props — 72, Fair

We assess whether the title, subtitle, and hero communicate the product’s true value.

The headline is **“The market behind AI hardware.”** The supporting description is **“Buy and sell GPUs with verified counterparties and price discovery.”**

### Working

- The hero chart shows real GPU prices.
- The subhead names buyers, sellers, and trust.
- The YC badge adds instant credibility.

### Could improve

- The headline describes a category rather than an outcome.
- The subhead is buried in the right rail.
- The page does not express the pain of opaque pricing.

### Value-proposition ranking

1. Vast.ai — 78
2. Shadeform — 78
3. SFCompute (San Francisco Compute) — 76
4. Stoa — 72
5. GPUList — 42

## Information hierarchy — 78, Fair

We assess whether the design helps or inhibits the page’s message.

1. **Hero Sign up button:** The small, low-contrast grey primary CTA sits at nearly the same visual weight as **“Contact our team,”** so no single action wins the scan.
2. **Six-link navigation row:** Products, Data, Research, About, Contact, and Log in create nine exits competing for attention before the hero CTA.
3. **Learn more banner:** A pill-styled announcement CTA at the top competes with Sign up as the first clickable element.
4. **Chart price labels:** Tiny monospace labels such as **“H100 SXM5 · $25,860”** are nearly illegible at the displayed scale, reducing the chart’s proof value.

[View layout plan](https://www.lazyweb.com/backlog?site=stoaexchange.com#opt-information-hierarchy) to turn these callouts into a sequenced plan of what to keep, move, merge, or remove.

## Mobile web — 86, Strong

We assess the phone experience as a first-class experience.

![Mobile web annotations on the mobile capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/stoaexchange.com-mobile.jpg?v=2026-09-20T05%3A55%3A14.939%2B00%3A00)

1. **Promo announcement bar:** A second header is stacked above the navigation. Its **“Learn more”** CTA competes with Sign up and pushes the hero downward.
2. **Chart price labels:** Monospace labels such as **“GB200 NVL · $67,400”** shrink to near-illegible size on the phone viewport.

## Competitors

Competitors are inferred from product, audience, and value proposition.

2. [Shadeform — shadeform.ai — 73](https://www.lazyweb.com/growth-score/site/shadeform.ai)
