The visible trust signal for Reason Machines is a **“Backed by Y Combinator”** badge above the hero headline.

### Trust comparison

| Product | Trust read |
| --- | --- |

| Factory | No visible trust signal identified. |
| Codegen | Terminal demo running `codegen search "summarize a PR"` with real directory results |
| OpenAI Codex | Implicit context: OpenAI Codex may benefit from pre-existing familiarity among its target audience. |
| Cursor Background Agents (Anysphere) | Detailed “Cursor Desktop” product UI showing the “Plan Mission Control” agent workflow and Cursor CLI output |

The trust-category ranking is:

1. Devin (Cognition) — 64

## Value props — 76, Fair

We evaluate whether the title, subtitle, and hero sell the product's true value.

Reason Machines’ headline is:

> “Reason Agent: Your team's autonomous software engineer.”

### Working

- The headline names the true value in one line.
- The hero demo shows a real PR with diff stats.
- “Backed by Y Combinator” adds credibility.

### Could improve

- There is no subhead, leaving zero specifics in the copy.
- Numbers live in the screenshot rather than the headline.
- There is no emotional or outcome-based hook.

The value-props ranking is:

1. Codegen — 80
2. Reason Machines — 76
3. Devin (Cognition) — 76
4. Cursor Background Agents (Anysphere) — 76
5. Factory — 58
6. OpenAI Codex — 38

## Information hierarchy — 78, Fair

We evaluate 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/reasonmachines.com.jpg?v=2026-09-20T21%3A10%3A11.92%2B00%3A00)

1. **Announcement banner arrow:** The “Introducing Reason Agent 1.0” banner is a full-width exit path above the headline and competes with the fold’s one action.
2. **Navigation links row:** Five equal-weight navigation links plus a high-contrast “Log in” button create six exits before the hero CTA.
3. **Product screenshot detail:** The three-pane app capture contains branch stats, reviewers, checks, and other micro-copy that reads as noise at fold scale rather than as one legible outcome.
4. **Backed by YC pill:** The clickable “Backed by Y Combinator ›” chip sits directly above the headline and invites an exit before the value proposition lands.

## Mobile web — 84, Strong

We evaluate the phone experience as a first-class citizen.

![Mobile web annotations on the mobile capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/reasonmachines.com-mobile.jpg?v=2026-09-20T21%3A10%3A11.92%2B00%3A00)

1. **Shrunken desktop screenshot:** The three-pane desktop UI is scaled to phone width, making all its text illegibly small.
2. **Try Reason CTA:** The button occupies roughly half the column width instead of using the full-bleed tap target available on mobile.

## CTA — 86, Strong

We evaluate the primary CTA’s copy, size, verb, and cost-feel. The displayed CTA is **“Try Reason for free.”**

### Problems

- The CTA has four words and is just over the ideal length.
- It does not echo the payoff in the headline promise.

The CTA ranking is:

1. Reason Machines — 86
2. Devin (Cognition) — 82
3. OpenAI Codex — 82
4. Codegen — 78
5. Factory — 73
6. Cursor Background Agents (Anysphere) — 73
