## Trust — 32, Poor

Trust measures proof that the product is real, competent, and safe to try.

![Mosaic, Conductor, Omnara, and Vibe Kanban trust examples](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/mosaic.inc.jpg?v=2026-09-20T05%3A14%3A53.355%2B00%3A00)

### Trust signals shown

| Product | Trust read |
|---|---|
| Mosaic | A visible install command, `$ brew install emergent-inc/tap/mosaic && mosaic install`, shows a real installable CLI. |
| Conductor (by Melty) | “feels like going from typing with two fingers to having eight arms” — Frank, Product Designer, Thinking Machines. |
| Terragon | No visible trust signal identified. |
| Vibe Kanban | A “Works with” integration-icon row shows recognizable AI-tool logos, including OpenAI, beneath the CTA. |
| Omnara | A “Backed by Y Combinator” badge appears above the headline. |

### Trust ranking

1. [Conductor (by Melty)](https://www.lazyweb.com/growth-score/site/conductor.build) — 74
2. [Omnara](https://www.lazyweb.com/growth-score/site/omnara.com) — 52
3. [Terragon](https://www.lazyweb.com/growth-score/site/terragonlabs.com) — 42
4. [Vibe Kanban](https://www.lazyweb.com/growth-score/site/vibekanban.com) — 38
5. Mosaic — 32

The **Proof section builder** is available at [Build proof section](https://www.lazyweb.com/backlog?site=mosaic.inc#opt-trust-signals). It helps choose proof signals and produce copy and placement for a stronger trust section.

## Value props — 62, Fair

This category asks whether the title, subtitle, and hero sell the product’s true value.

Mosaic’s headline is **“Everyone's AI coding sessions, in one place.”**

### What works

- It names the object: AI coding sessions.
- “In one place” states a clear outcome.
- The brew command signals developer-native ease.

### What could improve

- There is no subhead expanding the value.
- The hero art is decorative and does not show the product.
- There are zero proof points or specifics.

### Value-proposition ranking

1. [Conductor (by Melty)](https://www.lazyweb.com/growth-score/site/conductor.build) — 78
2. [Omnara](https://www.lazyweb.com/growth-score/site/omnara.com) — 68
3. Mosaic — 62
4. [Vibe Kanban](https://www.lazyweb.com/growth-score/site/vibekanban.com) — 62
5. [Terragon](https://www.lazyweb.com/growth-score/site/terragonlabs.com) — 45

## Information hierarchy — 72, Fair

This category asks whether the design helps or inhibits what the page is trying to say.

![Information hierarchy annotations on the desktop capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/mosaic.inc.jpg?v=2026-09-20T05%3A14%3A53.355%2B00%3A00)

The report identifies three issues:

1. **Truncated install command:** The brew command is cut off mid-string on desktop, making the developer path unusable at a glance while giving it equal weight with Get Started.
2. **Left-aligned nav row:** Sign in, Memo, and Contact appear first in the top-left scan path, creating three exits before the headline is read.
3. **For agents link:** A vague underlined exit directly beneath the CTA stack attracts clicks without explaining where it leads.

[View layout plan](https://www.lazyweb.com/backlog?site=mosaic.inc#opt-information-hierarchy) to turn these callouts into a sequenced page plan.

## CTA — 72, Fair

This category evaluates CTA copy, size, verb, and cost-feel.

### Problems identified

- The label is generic and names no payoff.
- It does not echo the headline promise.
- The click destination is unclear.

### CTA ranking

1. [Conductor (by Melty)](https://www.lazyweb.com/growth-score/site/conductor.build) — 82
2. [Omnara](https://www.lazyweb.com/growth-score/site/omnara.com) — 78
3. Mosaic — 72
4. [Vibe Kanban](https://www.lazyweb.com/growth-score/site/vibekanban.com) — 68
5. [Terragon](https://www.lazyweb.com/growth-score/site/terragonlabs.com) — 30

The **CTA rewrite studio** is available at [Rewrite this CTA](https://www.lazyweb.com/backlog?site=mosaic.inc#opt-cta-writing). It generates primary and secondary CTA options grounded in Mosaic’s offer and visitor objections.

## Mobile web — 78, Fair

This category evaluates 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/mosaic.inc-mobile.jpg?v=2026-09-20T05%3A14%3A53.355%2B00%3A00)

The report identifies three mobile issues:

1. **Uncollapsed desktop nav:** The “Sign in / Memo / Contact” row is carried over from desktop instead of collapsing into a mobile menu.
2. **Wrapped install command:** The brew command breaks `emergent-inc/tap/mosaic` across two lines, making the copy target look garbled.
3. **Small “For agents” link:** The underlined text link is a tiny tap target close to the install box above it.
