## Score over time

| Report date | Overall score | Change or note |
|---|---:|---|
| September 22, 2026 | 76 | Live; overall +12, Trust +26, Information hierarchy +14 |
| [May 20, 2026](https://www.lazyweb.com/growth-score/history/2026-05-20) | 64 | Overall +2, CTA −4, Trust +4 |
| [April 17, 2026](https://www.lazyweb.com/growth-score/history/2026-04-17) | 62 | First tracked report; strongest Value props 74, weakest Trust 44 |

## CTA — 68, Fair

We assess whether the primary CTA’s copy, size, verb, and perceived cost earn the click. LunaBill’s visible CTA is **“Talk to us.”** Comparable captured CTA examples are **“See it in action”** for Infinitus and **“Book a Demo”** for SuperDial (SuperBill).

### Problems identified

- A sales-call click feels costly.
- The label has no value payoff.
- The CTA does not echo the headline promise.

### CTA ranking

1. Infinitus — 76
2. SuperDial (SuperBill) — 72
3. LunaBill — 68
4. Adonis — 68
5. Anterior — 64

Our **CTA rewrite studio** can [rewrite this CTA](https://www.lazyweb.com/backlog?site=lunabill.com#opt-cta-writing) by generating primary and secondary options grounded in LunaBill’s offer and visitor objections.

## Mobile web — 72, Fair

We evaluate the phone experience as a first-class experience. The report identifies one issue:

1. **Talk to us button:** it is desktop-proportioned at approximately **40% width**; on mobile it should be full-bleed and thumb-friendly.

Our **Mobile fix plan** can [show the mobile fixes](https://www.lazyweb.com/backlog?site=lunabill.com#opt-mobile-web) as a prioritized implementation checklist.

## Trust — 74, Fair

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

| Company | Trust signal identified |
|---|---|
| LunaBill | A **“Backed by Y Combinator”** badge directly under the primary CTA |
| Adonis | Customer logo bar including ApolloMD, Commonwealth Pain & Spine, Baptist Health South Florida, Heart & Vascular Partners, and CareAbo |
| SuperDial (SuperBill) | No visible trust signal identified |
| Infinitus | A **“>90% positive ratings from patients”** metric strip beneath the hero CTA |
| Anterior | **“Florence: our clinical AI system for regulated and complex environments”** |

### Trust ranking

1. LunaBill — 74
2. Adonis — 72
3. Infinitus — 58
4. SuperDial (SuperBill) — 44
5. Anterior — 42

Our **Proof section builder** can [build a proof section](https://www.lazyweb.com/backlog?site=lunabill.com#opt-trust-signals) by selecting proof signals and providing copy and placement for a stronger trust section.

## Information hierarchy — 82, Strong

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

![Information hierarchy annotations on the desktop capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/lunabill.com.jpg?v=2026-09-22T00%3A22%3A38.584%2B00%3A00)

1. **Five-link navigation row:** Pricing, FAQ, Case study, About, and Blog are five equal-weight exits competing with conversion before the headline is read.
2. **Navigation “Talk to us”:** It duplicates the hero’s primary CTA at full weight, splitting emphasis between two identical green buttons in one viewport.
3. **“See how it works”:** This outlined button is nearly the same size as the primary CTA and diverts clicks into exploration instead of contact.
4. **Faint partner logos:** Tiny, low-contrast logos under **“WORKING CLAIMS FOR”** are illegible at this size, wasting the fold’s only social-proof strip.

## Value props — 86, Strong

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

### LunaBill’s headline and supporting copy

> **“Your claims don’t chase themselves. Luna does.”**
>
> “LunaBill’s AI agents work your entire AR queue: portals, payer calls, denials, appeals. Your team reviews outcomes, not status updates.”

### What is working

- The headline names the real job with wit.
- The subhead lists concrete accounts-receivable tasks.
- The hero demonstrates a claim moving to **Paid**.

### What could improve

- There is no outcome metric such as days or dollars.
- Proof numbers appear only in the mockup.
- The logos are unlabeled and therefore weak as proof.

### Value-proposition ranking

1. LunaBill — 86
2. Infinitus — 78
3. Adonis — 72
4. SuperDial (SuperBill) — 70
5. Anterior — 62

The hero visual is a product demonstration. It shows sample interface content, including a claim labeled **“CLAIM #4471 · AETNA PPO,”** an amount of **$1,324.00**, **“45 days unpaid,”** and a progression through **“Stuck 45 days,” “Portal checked,” “Payer called,”** and **“Paid.”** These are demonstration details, not reported LunaBill performance results.
