# Workers IO YC F26 Landing Page Growth Score

We are Workers IO, and our website is [workers.io](https://workers.io/). Our product is described through the headline **“Simulation Environments for Verifying Mission Critical Software”** and the supporting statement **“Deterministic virtual machines to verify your entire system under millions of realistic production scenarios.”**

This Lazyweb Growth Score report evaluates our landing page against five dimensions and compares us with other products in the YC F26 set. The report was updated **September 20, 2026**.

## Overall result

Our **Growth Score is 62 of 100**. The report identifies **Trust** as our weakest score.

## Trust — 48, Poor

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

The report compares the proof signals visible on several pages:

| Product | Trust read |
|---|---|
| Workers IO | A **“BACKED BY” Y Combinator investor badge** above the headline |
| Antithesis | Customer logo strip labeled “Trusted by engineering teams building mi…” with Replit, Railway, Confluent, MongoDB, and Mysten Labs |
| Jepsen | Embedded talk video, “Computers are bad, actually \| Kyle Kingsbury, Jepsen,” with Antithesis and AWS branding |
| FIS (Filibuster / fault injection alternatives) — Gremlin | “Reliability Report” product dashboard screenshot with an Average Company Reliability Score and a Company Risks Over Time chart |
| Turmoil (AWS) — replaced by Coroot? (excluded) | Customer logo strip with GitLab, Deloitte, GoDaddy, DoorDash, Remitly, Alaska, Bestseller, and Bentley |

### Trust ranking

## Mobile web — 55, Fair

Mobile web measures whether the phone experience functions as a first-class experience.

The mobile capture is missing, so the score is based only on responsive signals in the desktop capture and is capped. The desktop fold has one clear value statement, a sparse three-link navigation, and a single **“Book a Demo”** CTA, suggesting that the layout should collapse cleanly.

The report identifies two risks:

- The primary **“Book a Demo”** button appears only in the header. On a phone, it may hide behind a hamburger menu and disappear from the first viewport.
- The floating chat prompt, **“What reliability problems does Wo…”**, sits low-center and may crowd thumb territory on mobile.

The largest recommended improvement is a verified mobile capture with a full-width **“Book a Demo”** button in the hero rather than only in the navigation.

[View mobile fixes](https://www.lazyweb.com/backlog?site=workers.io#opt-mobile-web) to convert the findings into a prioritized implementation checklist.

## CTA — 62, Fair

CTA evaluation covers copy, size, verb, and perceived cost: whether the primary CTA earns the click.

![Workers IO CTA capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/workers.io.jpg?v=2026-09-20T06%3A45%3A54.246%2B00%3A00)

Our visible primary CTA is **“Book a Demo.”** The report identifies these problems:

- “Demo” implies the cost of a sales call.
- The CTA is navigation-sized rather than a hero-level CTA.
- It competes with the floating chat input.
- The chat submit control is an unlabeled arrow.

### CTA ranking

1. [Turmoil (AWS) — replaced by Coroot? (excluded)](https://www.lazyweb.com/growth-score/site/temporal.io) — 84
2. [FIS (Filibuster / fault injection alternatives) — Gremlin](https://www.lazyweb.com/growth-score/site/gremlin.com) — 70
3. [Antithesis](https://www.lazyweb.com/growth-score/site/antithesis.com) — 66
4. Workers IO — 62
5. [Jepsen](https://www.lazyweb.com/growth-score/site/jepsen.io) — 42

[Rewrite this CTA](https://www.lazyweb.com/backlog?site=workers.io#opt-cta-writing) to generate primary and secondary CTA options grounded in our offer and visitor objections.

## Information hierarchy — 72, Fair

Information hierarchy evaluates whether the design helps or inhibits the page’s message.

![Information hierarchy annotations on the desktop capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/workers.io.jpg?v=2026-09-20T06%3A45%3A54.246%2B00%3A00)

The annotated desktop capture identifies four elements:

1. **Book a Demo button:** A small black button pinned to the far top-right sits outside the hero scan path, and no CTA repeats near the headline.
2. **Chat input overlay:** A floating **“What reliability problems…”** prompt competes with the demo CTA and covers the hero illustration mid-fold.
3. **GitHub repository link:** The `workersio/skills` link sits directly beside the primary CTA at equal prominence, diverting developer attention off-site.
4. **Hero circuit illustration:** A large diagram occupies the lower half of the fold without a caption or product framing to explain what it depicts.

[View layout plan](https://www.lazyweb.com/backlog?site=workers.io#opt-information-hierarchy) to turn these callouts into a sequenced plan to keep, move, merge, or remove elements.

## Value props — 72, Fair

Value-proposition evaluation covers the title, subtitle, and hero: whether they sell our product’s true value.

### Our headline and supporting statement

> **Simulation Environments for Verifying Mission Critical Software**
>
> *Deterministic virtual machines to verify your entire system under millions of realistic production scenarios.*

### What works

- The headline names the category and audience precisely.
- **“Deterministic”** is a credible technical hook.
- **“Millions of scenarios”** signals scale.

### What could improve

- The message does not express an emotional stake or address outage fear.
- It includes no hard numbers or customer proof.
- The hero graphic decorates rather than demonstrates the product.

### Value-proposition ranking

1. [FIS (Filibuster / fault injection alternatives) — Gremlin](https://www.lazyweb.com/growth-score/site/gremlin.com) — 82
2. [Antithesis](https://www.lazyweb.com/growth-score/site/antithesis.com) — 76
3. Workers IO — 72
4. [Turmoil (AWS) — replaced by Coroot? (excluded)](https://www.lazyweb.com/growth-score/site/temporal.io) — 68
5. [Jepsen](https://www.lazyweb.com/growth-score/site/jepsen.io) — 52
