**Answer.** Across 4,814 detected experiments (July 2026), the fintech apps with the deepest signup-focused programs are Chime (at least 17 signup of 56 total) and Capital One (at least 14 of 19). [1] Fintech testing in this corpus concentrates on account acquisition, not paywalls — Chime, Capital One, and Bank of America show near-zero detected paywall experiments. [1] These are observed variations, not confirmed A/B tests.

> Chime leads fintech signup testing with at least 17 signup experiments of 56 total (July 2026); Capital One follows with at least 14 of 19.

## The finding

Among fintech apps in the corpus, signup is the dominant test surface. Chime has at least **17 signup experiments of 56 total**, and Capital One at least **14 of 19**. [1] Crucially, these apps show near-zero detected paywall experiments (Chime 2, Capital One 0, Bank of America 0), confirming that fintech growth testing here targets account acquisition rather than monetization screens. [1]

## The leaderboard

| Company | Total | Signup (lower bound) | Paywall |
|---|---|---|---|
| Chime | 56 [1] | at least 17 [1] | 2 [1] |
| Capital One | 19 [1] | at least 14 [1] | 0 [1] |
| Bank of America | 14 [2] | at least 9 [2] | 0 [2] |
| Cash App | 16 [3] | at least 6 [3] | 0 [3] |
| Credit Karma | 30 [4] | at least 3 [4] | 0 [4] |

## How to apply it

If you build a fintech product, these companies are your closest experiment benchmarks — and the corpus signal is clear: point your test volume at signup and account setup, not a paywall. Chime and Capital One are the two with enough detected signup volume (17 and 14) to study seriously. Because individual diffs aren't itemized here, cite the surface concentration. 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 (screen category unlabeled on 1,425 experiments). [5] The paywall template does not apply to these apps. [1]

## The numbers

| Stat | Computed from |
| --- | --- |
| Chime 56 total / 17 signup / 2 paywall; Capital One 19 / 14 / 0 | company_total:chime (56; signup 17, paywall 2); company_total:capital-one (19; signup 14, paywall 0) |
| Bank of America 14 total, at least 9 signup, 0 paywall | company_total:bofa (14; signup 9, paywall 0) |
| Cash App 16 total, at least 6 signup, 0 paywall | company_total:cash-app (16; signup 6, paywall 0) |
| Credit Karma 30 total, at least 3 signup, 0 paywall | company_total:credit-karma (30; signup 3, paywall 0) |
| 1,425 of 4,814 experiments have no screen category | screen_category_null_on_experiments (1425/4814) |

## Methodology

Universe: detected experiments at fintech apps within 4,814 diffs (276 companies), July 2026. Extraction: per-company signup/paywall splits (COUNT DISTINCT experiment_id). Caveat: detected variations only; splits are lower bounds.
