What is the most common growth engine that apps actually use?
PR is the single most-cited growth engine, tagged on 330 of 599 companies (55%), narrowly ahead of paid performance marketing at 298 (50%) and word of mouth at 296 (49%)[1]. Product-led self-serve, the motion founders obsess over, sits fifth at 179 (30%), and pure sales-led is near the bottom at 59 (10%)[1]. The takeaway: the median company runs several engines at once — earned, paid, and organic — rather than betting on one[1].
PR leads the growth-engine leaderboard at 330 of 599 tagged apps (55%), with PLG only fifth at 30% — July 2026.

The growth-engine leaderboard
Share of the 599 growth-engine-tagged companies citing each engine (multi-select, so shares sum past 100%)[1]:
| Growth engine | Companies | 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% |
| Marketplace liquidity | 72 | 12% |
| Sales-led (B2B) | 59 | 10% |
| Cold outreach | 58 | 10% |
The top four engines are all earned/paid/organic demand levers; explicit product and sales motions rank lower[1].
How to apply it
Don't read the leaderboard as 'do PR' — read it as 'most durable apps run a portfolio.' The top three engines are each cited by roughly half the corpus, which only works because companies stack them[1]. Use PR, paid, and word of mouth as the broad table stakes, then let your archetype and category (siblings) tell you whether PLG, content, or sales is the differentiating fifth engine to invest in[1]. If you are a founder betting everything on one channel, you are behaving unlike the tagged median company.
Caveats
Denominator is the 599 companies with a growth_engine tag inside Lazyweb's tagged subset — not the 62,376-company table[1]. growth_engine is a multi-select array; each figure is 'companies citing engine X,' so the column sums well past 100% and cannot be read as a partition[1]. Tagging reflects Lazyweb's judgement of observable go-to-market behavior, not company self-report.
