## Ranking

1. [Serna Bio — 64](https://www.lazyweb.com/growth-score/site/serna.bio)
2. [Strand Therapeutics — 51](https://www.lazyweb.com/growth-score/site/strandtx.com)
3. [Senti Biosciences — 48](https://www.lazyweb.com/growth-score/site/sentibio.com)
4. **Exonic — 46**

## CTA — 30, Poor

We assess whether the primary CTA’s copy, size, verb, and cost-feel earn the click. The comparison identifies these problems for the example landing-page treatment:

- No CTA anywhere on the fold.
- Navigation links are the only path forward.
- The headline promise has no next step.

The CTA comparison ranks Serna Bio at 58, Senti Biosciences at 40, Exonic at 30, and Strand Therapeutics at 30.

[Rewrite this CTA](https://www.lazyweb.com/backlog?site=exonic.ai#opt-cta-writing) is a PRO feature for generating primary and secondary CTA options grounded in Exonic’s offer and visitor objections.

## Value props — 48, Poor

We assess whether the title, subtitle, and hero sell the product’s true value. The report identifies Exonic’s headline as:

> “Imagine if medicine could sense and adapt to disease”

### Working

- Evocative, emotionally resonant vision line.
- Blue highlight on “sense and adapt” focuses the claim.
- YC badge lends early credibility.

### Could improve

- No subhead says what Exonic actually builds.
- “Imagine if” is hypothetical, not a claim.
- The hero visual decorates rather than demonstrates.

The value-proposition comparison ranks Serna Bio at 68, Strand Therapeutics at 62, Senti Biosciences at 52, and Exonic at 48.

## Trust — 48, Poor

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

| Company | Trust read |
|---|---|
| Exonic | “Backed by Y Combinator” badge with YC logo |
| Strand Therapeutics | “Strand is a clinical-stage biotechnology company with a pipeline of breakthrough mRNA therapeutics for cancers and auto |
| Senti Biosciences | “Senti Bio is a clinical-stage company developing a new generation of cell and gene therapies” copy on mobile |
| Serna Bio | No visible trust signal identified. |

The trust comparison ranks Exonic and Strand Therapeutics at 48, Senti Biosciences at 44, and Serna Bio at 44.

## Mobile web — 48, Poor

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

The annotated findings are:

1. **Headline over particles:** Hero copy sits on a dense particle field with no visible CTA in the fold; the blue “sense and adapt” span blends into the busy texture.
2. **Uncollapsed nav row:** Desktop “MEDIA TEAM” links carry into the phone header instead of a hamburger, and wide letter-spacing uses substantial header width.
3. **Pause motion control:** A utility control occupies the bottom-corner position a conversion CTA should own and competes with the YC badge as one of the only footer actions.

[View mobile fixes](https://www.lazyweb.com/backlog?site=exonic.ai#opt-mobile-web) is a PRO feature for converting the findings into a prioritized implementation checklist.

## Information hierarchy — 58, Fair

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

The annotated findings are:

1. **MEDIA TEAM navigation:** The prominent buttons lead away from conversion, making exits the default action.
2. **Headline over particles:** The dot field runs behind “sense and adapt,” softening the legibility of the accented key phrase.

[View layout plan](https://www.lazyweb.com/backlog?site=exonic.ai#opt-information_hierarchy) is a PRO feature for turning the callouts into a sequenced keep, move, merge, or remove plan.
