Product-led growth · a build guide
A 1% gain in acquisition moves the bottom line about 3%. A 1% price change moves operating profit 11.1%. Product-led growth is how you get at the other three levers — here is the build order, stage by stage.
A 1% move on each lever, and what it returns
Ranked best to worst ROI
Where most companies spend
Method: acquisition, ARPU and churn are modeled against bottom-line profit; the 11.1% price figure is HBR's operating-profit result. Different baselines, same conclusion — price and monetization beat acquisition by roughly 4×.
We'll walk your funnel and name the broken stage before you commit to anything.

$199,800 a year — 3.7× what the same 1% of acquisition returns.
$12,000,000 × 15% = $1,800,000 operating profit · $1,800,000 × 11.1% = $199,800
The build order
PLG isn't a pricing page with a free button on it. It's a free tier that creates a reason to upgrade, an activation metric that tells you whether anyone got there, economics that prove it, and an org built to act on the data weekly.
01
Design the free tier
Uncomfortable but valuable.
02
Define activation
Key action plus frequency.
03
Instrument the economics
Quick Ratio and LVR.
04
Stand up the growth team
Beside product, not inside it.
05
Make support the sales motion
One journey, not three funnels.
Stage 01 — the free tier
Dropbox's 2GB is the archetype: enough to become a habit, not enough to live in. Limit on one axis — feature, capacity, or use case.
Best practice
Red flag: conversion under 3% at mid-market, or a free tier nobody ever bumps against.
Free → paid conversion, banded
Self-serve SaaS. Find your row, then your band.
Segment
Weak
Acceptable
Strong
SMB
< 6%
6–10%
> 10%
Mid-market
< 3%
3–5%
> 5%
Mid-market bands sit lower because seats and procurement, not curiosity, decide the upgrade. Same conversion rate means two different diagnoses.
Stage 02 — activation
Acquisition, activation, retention, referral, revenue. The problem is almost never traffic — it's people landing and leaving.
Method
Activation isn't a one-time trial event. Each feature has its own activation, long after the trial ends.

The biggest single drop is the invite step, and it sits before every downstream action. That's the stage to fix — not the ad spend feeding the top.
Stage 03 — retention economics
Quick Ratio grades the engine you already have. Lead velocity rate tells you what next quarter looks like, this month.
Best practice
Red flag: a Quick Ratio under 1. You are losing MRR faster than you add it, and more traffic will not fix that.

Target MRR growth
5.0% / mo
LVR target
5.5–6.0% / mo
5.0% × 1.10 = 5.5%. 5.0% × 1.20 = 6.0%. Miss the band two months running and the MRR miss is already booked.
Stage 04 — the growth org
A cross-functional squad — PM, iOS, Android, web — bonused on conversion-rate lift and shipping nightly. Perfect is BS.
Best practice
Red flag, per Jeff Diana: going so product- and eng-centric that sales, marketing and CS stop showing up.

Stage 05 — helpfulness as the motion
MQL, SQL and PQL are one journey, not three funnels. A hand-raise on the pricing page and an in-product seat-limit hit are the same signal arriving through different doors.
Sales
Proactively helping prospects who aren't paying yet
Same behaviour as support, aimed one step earlier in the journey.
Customer success
Proactively helping the ones who are
The expansion lever and the churn lever are the same team.
The offer
A world-class manager, giving expertise to managers using the tool
The highest-value thing you can put in front of a free user.
Scale it on-site
Run helpfulness through Drift — and put marketing in there too
Conversational coverage on the pages where intent shows up.
Orientation
It's about the user, not us
Every prompt, email and paywall gets read against that test first.
The rule that governs the rest
What you measure is what you optimize for.
Pick the activation metric carefully. The org will bend itself toward it.
Before you launch
Trello and Zapier are the proof: it has to be organizational DNA, not a quarterly initiative. If the free tier, the activation metric and the growth squad don't survive contact with the next roadmap fight, the motion never starts.
No deck, no discovery marathon. One call to find the stage that's leaking.
The five checks, in order
We engineer growth systems. JayOh builds the RevOps architecture, GTM execution and data infrastructure that turn messy revenue operations into predictable pipeline for B2B SaaS and PE-backed teams.
