**Answer.** PR leads at 330 of 599 growth-tagged apps (55%), followed by paid performance marketing (298 = 50%) and word of mouth (296 = 49%) [1]. Network effects (217) and product-led self-serve/PLG (179) round out the top five [1]. If you are choosing a growth motion, the data shows most apps run several engines at once rather than betting on one — there is no single dominant channel.

> PR (330), paid marketing (298), and word of mouth (296) are the top three of 599 growth-tagged apps — July 2026.

## The growth-engine leaderboard

Across 599 growth-tagged apps [1]:

| Growth engine | Apps | Share of 599 |
|---|---|---|
| PR | 330 | 55% |
| Paid performance marketing | 298 | 50% |
| Word of mouth | 296 | 49% |
| Network effects (social graph) | 217 | 36% |
| Product-led self-serve (PLG) | 179 | 30% |
| Content-led / SEO | 150 | 25% |
| Hardware/Distribution bundling | 125 | 21% |
| Social media | 120 | 20% |
| Channel / partnership-led | 116 | 19% |
| UGC / creator-led | 111 | 19% |

Counts sum well past 599 — the tag is multi-valued, so most apps carry several engines.

## How to apply it

The top three engines each appear in roughly half of tracked apps, which means PR, paid, and word of mouth are the default trio rather than mutually exclusive choices [1]. Sales-led (59), cold outreach (58), land-and-expand (46), and product-led sales (34) sit lower overall because they concentrate in B2B/Enterprise archetypes — pick them based on your archetype, not the global leaderboard. Use the by-archetype and by-category cuts to localize this.

## Caveats

Denominator is the 599 apps with a growth_engine tag, not the full corpus [1]. The tag is multi-valued, so shares sum past 100% and each figure is 'apps carrying engine X.' Engine assignment is an analyst attribute, not a self-reported channel-mix from the companies.

## Methodology

Universe: the 599 growth-engine-tagged apps in Lazyweb's ~800-app tracked corpus, July 2026 pull. Method: multi-valued tag prevalence. Caveat: counts sum past the app total; engine assignment is an analyst attribute, not self-reported.
