Growth Loops Instead of Funnels (PLG)

Elena Verna's counter-model to the linear sales funnel: growth comes from self-reinforcing loops in which one cycle's output feeds the next cycle's input, the product itself becomes the acquisition, retention, and monetization engine. Sales is added later as an expansion layer (PLG to PLS).

When you need this method

Your growth is a linear funnel: paid or sales input must constantly be refilled at the top, or the inflow dries up. Every won customer is an endpoint, generating no further inflow. For products with a natural collaboration or visibility component, this model wastes the strongest lever: the usage itself.

Approach

  1. 1Build the retention loop first: a clear activation path leads new users to the first value moment, recurring usage anchors the product.
  2. 2Then identify the acquisition loop: where does usage naturally create visibility or invitations, shared artifacts, invited colleagues, public output?
  3. 3Instrument each loop as a cycle (input, action, output, feedback) and measure cycle throughput instead of just funnel stages.
  4. 4Layer sales on top of usage as expansion (product-led sales): you sell where teams already use the product.

Typical application

A typical case: a B2B SaaS for team collaboration has so far won customers through outbound and demos, expensive and linear. Analysis shows users already share output with colleagues who do not know the product. The company deliberately builds that moment out: shared content becomes usable for recipients, and joining the team is the natural next step. Only once the usage base grows inside larger organizations does a small sales team engage precisely where many individual users are already active, sales harvests what the loop has generated.

Limits and counter-indications

Loops require usage to naturally create visibility or invitations, for single-seat tools without a collaboration moment, this can hardly be forced. Building them takes time and product investment that delivers no short-term pipeline. For high-priced enterprise products with buying committees, a sales-led motion often remains the better core; loops are then a complement, not a replacement.

How to measure impact

Loop throughput instead of funnel stages: share of users who generate new users, loop cycle time, plus free-to-paid conversion and retention per segment.
