# Kalpa Labs Landing Page Growth Score | YC F25

[← Back to YC F25](https://www.lazyweb.com/yc-f25)

[Kalpa Labs](https://kalpalabs.ai/)

We assess Kalpa Labs’ landing page through our Growth Score report. Kalpa Labs is described in the report as an audio research lab working toward generalist audio models—models that follow instructions and learn new tasks in context. Its first conversational speech models are described as **in beta today**, with actions to direct a scene in Studio, talk to a model, and use the API.

**Overall Growth Score:** **70/100**, updated **Sep 22, 2026**. The weakest category is **Trust**.

## Category scores

| Category | Score |
| --- | ---: |
| Trust | 52 |

## Value props — 62, Fair

This section evaluates whether the title, subtitle, and hero sell the product’s true value.

The report quotes the headline **“Towards generalist audio models.”** and the following description:

> Kalpa Labs is an audio research lab working towards generalist audio models: models that follow instructions and learn new tasks in context. Our first conversational speech models are in beta today. Direct a scene in Studio, talk to a model

**Working**

- The subhead names three concrete actions.
- “In beta today” grounds the mission.
- The YC badge adds credibility proof.

**Could improve**

- “Towards” signals unfinished value.
- No numbers or outcomes appear anywhere.
- The hero decorates; no product demo is shown.

Value-proposition comparison scores:

1. Cartesia — 72
2. Rime — 68
3. Kalpa Labs — 62
4. Hume AI — 62
5. Sesame — 58
6. ElevenLabs — 55

## Information hierarchy — 78, Fair

This section 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/kalpalabs.ai.jpg?v=2026-09-22T21%3A29%3A00.382%2B00%3A00)

The report identifies four hierarchy issues:

1. **Launch report banner:** A full-width red-tinted announcement sits above the hero and pulls first attention toward an exit link.
2. **Secondary CTA pair:** OPEN STUDIO and READ THE DOCS share the primary button’s size and row, splitting the click three ways.
3. **Header TALK TO KALPA:** This duplicates the hero primary CTA at equal black weight, creating two competing focal points.
4. **Nav link row:** Realtime, Studio, Docs, and Careers offer four exits before the visitor reaches the value proposition.

## CTA — 78, Fair

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

![Kalpa Labs and Rime CTA comparison](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/kalpalabs.ai.jpg?v=2026-09-22T21%3A29%3A00.382%2B00%3A00)

The report lists these problems with the primary CTA:

- It reads like “book a sales call.”
- It signals no commitment level.
- Beta status is not shown on the button.

CTA comparison scores:

1. Rime — 84
2. Kalpa Labs — 78
3. Cartesia — 74
4. ElevenLabs — 63
5. Hume AI — 62
6. Sesame — 48

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

## Mobile web — 78, Fair

This section evaluates the phone experience.

![Mobile web annotations on the mobile capture](https://zlfyzdmohcskkucuunmk.supabase.co/storage/v1/object/public/sites/growth-score/site/kalpalabs.ai-mobile.jpg?v=2026-09-22T21%3A29%3A00.382%2B00%3A00)

The report identifies three mobile issues:

1. **Announcement banner:** A two-line promotional banner with a dismiss X pushes the hero down and adds a competing message before the value statement.
2. **Beta badge pill:** A wide two-line badge wraps awkwardly and stacks a third message above the headline, crowding the top of the fold.
3. **Long body paragraph:** Eight lines of dense copy push the CTA stack to the very bottom edge of the first viewport.
