**Answer.** Lazyweb Research detected 43 distinct experiments at Crumbl (July 2026), of which at least 39 are on the home surface — one of the most home-concentrated test programs in the corpus. [1] With no detected paywall experiments, Crumbl's iteration is almost entirely on merchandising the weekly menu, not monetization. These are observed before/after variations with inferred rationale, not company-confirmed A/B tests.

## The finding

Lazyweb Research detected **43 distinct experiments** at Crumbl, with at least 39 on the home surface and 0 on any paywall. [1] Crumbl is the corpus's clearest example of a food-ordering app treating its home screen — where the rotating weekly menu lives — as the single most-tested surface. Nearly every detected experiment is about merchandising, not checkout or subscription.

## How to apply it

Crumbl is the benchmark for a menu-driven ordering app: when the product rotates weekly, the home/merchandising surface is where iteration concentrates (at least 39 of 43 detected experiments). If your ordering app tests checkout heavily but leaves the home menu static, Crumbl is evidence the merchandising surface is the higher-leverage test bed. No Crumbl experiments were detected in 2026. [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 of 4,814 corpus experiments. [cat_null]

## The numbers

| Stat | Computed from |
| --- | --- |
| 43 distinct experiments; at least 39 home | company_total:crumbl (value 43; home 39, signup 3, in-2026 0) |
| 1,425 of 4,814 experiments have no screen category | screen_category_null_on_experiments (1425/4814) |

## Methodology

Universe: 43 distinct Crumbl experiments (COUNT(DISTINCT experiment_id)) within 4,814 detected before/after UI diffs across 276 companies, July 2026. Extraction: LLM-inferred rationale on observed variations. Caveat: detected variations only, never company-confirmed A/B tests.

- [cat_null] Lazyweb Research analysis of 4,814 detected experiments (276 companies, ~800-app mobile corpus), July 2026. screen_category is NULL on 1,425 experiments, so all surface splits are lower bounds.
