## Score over time

The page includes a Growth Score history chart with series for SuperRadiant, Lila Sciences, Emerald Cloud Lab, Ginkgo Bioworks, Arctoris, and Periodic Labs.

## CTA — 48/100, Poor

We assess whether the primary CTA's copy, size, verb, and perceived cost earn a click.

### Problems identified

- There is no CTA in the hero on either viewport.
- On mobile, the CTA is hidden behind the hamburger menu.
- “Contact” feels costly and sales-oriented.
- The CTA has a small, navigation-sized footprint.

The CTA comparison ranks the supplied examples as follows:

1. Emerald Cloud Lab — 64
2. Ginkgo Bioworks — 62
3. Arctoris — 62
4. SuperRadiant — 48
5. Lila Sciences — 48
6. Periodic Labs — 44

The paid **CTA rewrite studio** can generate primary and secondary CTA options grounded in SuperRadiant's offer and visitor objections: [Rewrite this CTA](https://www.lazyweb.com/backlog?site=superradiant.co#opt-cta-writing).

## Trust — 48/100, Poor

We assess proof that a product is real, competent, and safe to try.

| Company | Trust read |
|---|---|
| SuperRadiant | “Backed by Y Combinator” badge in the hero |
| Lila Sciences | No visible trust signal identified. |
| Emerald Cloud Lab | “Trusted by” logo row featuring CSL, CMU, Biogen, Bristol Myers Squibb, GSK, Amgen, Argonne National Laboratory, and Stanford |
| Ginkgo Bioworks | Event banner: “REAL Summit 2026 · Seaport Boston · September 15 — FEATURING NOVO NORDISK” |
| Arctoris | No visible trust signal identified. |
| Periodic Labs | No visible trust signal identified. |

The trust comparison ranks the supplied examples as follows:

1. Emerald Cloud Lab — 78
2. Ginkgo Bioworks — 52
3. SuperRadiant — 48
4. Periodic Labs — 44
5. Lila Sciences — 42
6. Arctoris — 42

The paid **Proof section builder** helps choose proof signals and produce copy and placement for a trust section: [Build proof section](https://www.lazyweb.com/backlog?site=superradiant.co#opt-trust-signals).

## Mobile web — 58/100, Fair

We assess the phone experience as a first-class experience. The supplied mobile capture identifies one issue:

![Mobile web annotations on the mobile capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/superradiant.co-mobile.jpg?v=2026-09-20T06%3A39%3A29.832%2B00%3A00)

1. The **faded Y Combinator badge** uses low-contrast gray text over a dark image, so it reads as noise rather than as a trust signal.

The paid **Mobile fix plan** converts the mobile findings into a prioritized implementation checklist: [View mobile fixes](https://www.lazyweb.com/backlog?site=superradiant.co#opt-mobile-web).

## Value props — 62/100, Fair

The page's headline is **“Embodied Scientific Intelligence”** and its subhead is **“Robotic experimentalists that observe, hypothesize, and run experiments in the real world.”**

### What is working

- The subhead names concrete agents and actions.
- The YC badge adds credibility.
- The hero image signals real lab science.

### What could improve

- The H1 is an abstraction stack.
- No numbers or outcomes appear anywhere in the reviewed landing page.
- The image decorates the page but does not show robots.

The value-proposition comparison ranks the supplied examples as follows:

1. SuperRadiant — 62
2. Periodic Labs — 62
3. Emerald Cloud Lab — 58
4. Arctoris — 54
5. Ginkgo Bioworks — 48
6. Lila Sciences — 22

## Information hierarchy — 72/100, Fair

We assess whether the design helps or inhibits what the landing page is trying to communicate.

![Information hierarchy annotations on the desktop capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/superradiant.co.jpg?v=2026-09-20T06%3A39%3A29.832%2B00%3A00)

1. **Contact Us button:** The only CTA is stranded in the top-right corner, outside the hero scan path where the headline lands.
2. **Carousel dots:** A five-slide indicator means the hero message rotates, destabilizing the one headline the fold must land.
3. **Hero text block:** The headline and subtitle have no action beneath them, leaving the attention peak without anything to click.

The paid **Layout priority plan** turns these callouts into a sequenced plan of what to keep, move, merge, or remove: [View layout plan](https://www.lazyweb.com/backlog?site=superradiant.co#opt-information-hierarchy).
