**Answer.** Across 4,814 detected experiments spanning 276 companies (July 2026), signup and account-login screens account for roughly 376 labeled experiments — sign up (127), account login (167), and account setup (82). [1] At the company level, ChatGPT (at least 18 signup), Chime (17), Disney (17), and Capital One (14) lead the detected signup work. [2] These are observed variations, not confirmed A/B tests.

> Sign-up, account-login, and account-setup screens carry 376 labeled experiments across the corpus (July 2026); ChatGPT leads companies with at least 18 signup experiments.

## The finding

Across the corpus of **4,814 detected experiments** (276 companies), the labeled signup-adjacent categories total roughly **376 experiments**: sign up (127), account login (167), and account setup (82). [1] At the company level, the deepest detected signup programs are ChatGPT (at least 18), Chime (17), Disney (17), and Capital One (14). [2]

## The leaderboard

Signup-heavy companies span AI, fintech, and streaming.

| Company | Signup experiments (lower bound) |
|---|---|
| ChatGPT | at least 18 [2] |
| Chime | at least 17 [2] |
| Disney | at least 17 [2] |
| Capital One | at least 14 [2] |
| Bumble | at least 13 [2] |
| Adidas | at least 12 [2] |
| Delta | at least 12 [2] |
| Babbel | at least 11 [2] |
| Replit | at least 13 [2] |
| Zoom | at least 10 [2] |

## How to apply it

These are the apps to study when redesigning a signup or onboarding flow — they have the most detected iteration on those screens, so their current designs reflect the most experimentation. The recurring detected direction across them (Zoom, Replit, Wattpad, Brainly) is email-first entry, promoting links to buttons, and leading with value before credentials. Cite the per-company volume; individual diffs are covered on the company pages. All figures are detected variations. [1]

## Caveats

All figures are observed variations with LLM-inferred rationale, not company-confirmed A/B tests — no lift is measured. [1] Surface splits are lower bounds because screen category is unlabeled on 1,425 experiments. [3]

## The numbers

| Stat | Computed from |
| --- | --- |
| 376 labeled signup-adjacent experiments (sign up 127, account login 167, account setup 82) within 4,814 | top_experiment_screen_categories (sign_up 127, account_login 167, account setup 82) |
| Company signup leaders: ChatGPT 18, Chime 17, Disney 17, Capital One 14, Bumble 13, Replit 13, Adidas 12, Delta 12, Babbel 11, Zoom 10 | company_total signup splits: chatgpt 18, chime 17, disney 17, capital-one 14, bumble 13, replit 13, adidas 12, delta 12, babbel 11, zoom 10 |
| 1,425 of 4,814 experiments have no screen category | screen_category_null_on_experiments (1425/4814) |

## Methodology

Universe: 4,814 detected experiments across 276 companies, July 2026. Extraction: screen-category and per-company splits (COUNT DISTINCT experiment_id) on observed diffs. Caveat: detected variations only; splits are lower bounds.
