Product-led growth strategy: trials that pay without a sales team

In June 2022, Plausible Analytics passed $1M ARR ($83,637 MRR). It had "more than 7,000 paying subscribers" and "a completely independent, self-funded and bootstrapped team of four" (Plausible). It sold through a 30-day free trial. It also said: "We don't use paid advertising."

The early climb was slow. Co-founder Marko Saric shared the stages on Indie Hackers. It took 12 months to go from $0 to $400 MRR, then 9 more to reach $10k (Indie Hackers).

You probably do spend on ads. The rule still holds: a product led growth strategy works only when trials turn into payment on their own. This guide is part of our growth playbooks by business type.

What is a product led growth strategy?#

Product-led growth is a way of selling software in which the product itself wins, converts and keeps customers, instead of a sales team.

Blake Bartlett, then a partner at OpenView, is credited with coining the term in 2016 (Built In). OpenView has since stopped making new investments. Wes Bush's 2019 book Product-Led Growth made the idea mainstream. It describes making "your product the tool that helps you acquire, convert, and retain customers" (Apple Books).

PLG doesn't mean "no humans, ever." It means the default path to paying needs no human. Atlassian is the classic case. Its first annual report as a public company said: "We do not have a direct salesforce and our sales model does not include traditional, quota-carrying sales personnel" (SEC, Atlassian 20-F FY2016).

What stage is your self-serve SaaS at?#

These bands are my judgment, not a benchmark.

Plausible later doubled from $41.6k to $83.3k MRR in eight months (Indie Hackers). Self-serve compounds once the early leaks are fixed.

If you sell bigger contracts through demos, the B2B SaaS growth playbook fits you better.

The five moves that matter most#

Here's the order I'd work in.

1. Define activation by who pays#

Find the one early action that predicts payment. Group past sign-ups by what they did in their first days. Then compare how many in each group paid in Stripe. The method is in SaaS activation metric: the first action that predicts who pays.

Cost: one or two days of analyst time in a spreadsheet. Time to revenue: four to eight weeks, once an onboarding test has enough sign-ups.

2. Pick a trial model by payers per visitor#

Card-required trials convert better per sign-up, but start fewer trials. So compare payers per visitor.

First Page Sage, an agency, reports from its client data that opt-in trials convert 17.3% to paid and card-required trials 49.1%. Yet both produced about 13 paying customers per 1,000 visitors (First Page Sage). Growth Unhinged and ChartMogul surveyed 200 B2B products in January 2026. They found a median free-to-paid rate of 8%, and 30% for card-required trials (Growth Unhinged).

If you already run a free plan that converts poorly, try a reverse trial first. Users get paid features, then drop to the free plan. Only 7% of products in that survey used one. The trade-offs are in free trial vs freemium: which brings more paying customers?

Cost: a few days of billing and copy work. Time to revenue: one trial length plus two weeks to read.

3. Trigger trial emails from behavior#

Send the "connect your data" email only to people who haven't connected it. Tie each email to your activation action.

Card-required trials also need a clear reminder before the first charge. Stripe can email customers 7 days before a trial ends (Stripe Docs). See trial follow-up emails that turn sign-ups into paying customers for the full sequence.

Cost: two to four days to write and wire up. Time to revenue: the next trial cohort.

4. Show prices and let people pay alone#

A self-serve buyer who meets "Contact us" often leaves. Kyle Poyar warns PLG companies against hiding pricing and watering down self-serve plans (Growth Unhinged). Put prices on the page. Let anyone upgrade, add seats and pay by card without a call.

SaaS pricing page best practices lists 12 tests, judged by paying customers.

Cost: a week of design and billing setup. Time to revenue: one to two months for a readable test.

5. Add sales only for product-qualified accounts#

A product-qualified lead (PQL) is a user who has reached real value in your product and shows buying intent. Wes Bush defines it as "a lead who has experienced meaningful value using your product" (ProductLed).

Poyar's advice is to reach out based on what users have done in the product, not on every new sign-up. He also notes that the people who use your product "are generally not the same people as those who buy" (Growth Unhinged).

Most self-serve companies end up hybrid. In the 2026 Growth Unhinged survey, 80% of free-trial products had a human touchpoint when an enterprise user started a trial (Growth Unhinged). Even Atlassian's language changed. By 2022 its filing said its model "does not rely primarily on traditional, quota-carrying sales personnel" (SEC, Atlassian 20-F FY2022). Note "primarily."

My rule: add one sales-assist person when a few accounts a month hit your PQL rule and ask for invoices, security reviews or annual terms. Bartlett put it simply: "Your customers tell you when it's time to hire sales" (Built In).

Cost: one salary, often $100k+ a year with commission. Time to revenue: one to two quarters.

Which revenue numbers show PLG is working?#

Judge everything on payment. These are the numbers I'd review weekly.

Cost per paying customer is the one most teams skip. Two campaigns with equal trial costs can differ fourfold in who pays. CAC payback period shows how to turn this into months.

What to stop doing#

Judging campaigns by sign-ups. Ad platforms reward cheap sign-ups. The cost is budget that keeps flowing to people who never pay, often for months.

Calling every new sign-up. Poyar lists this as a common PLG mistake (Growth Unhinged). It annoys buyers and burns sales hours on accounts that would have paid anyway.

Hiding prices behind a demo form. Every self-serve buyer who leaves the pricing page is lost revenue you'll never see in a report.

Sending day-count drip emails to everyone. Activated users get noise and stuck users get nothing useful. You pay in lower trial-to-paid.

Making the free plan better to lift sign-ups. If the free plan solves the whole problem, fewer people pay, and you carry their support and hosting costs.

How to do this in Kratly#

1. Connect Google Ads, Meta Ads, your website and Stripe. Kratly ties each trial and each paying customer to the campaign, page or email that brought them.
2. Compare campaigns by cost per paying customer. Spot the ones whose trials rarely convert, even when sign-ups look cheap.
3. Check pages and emails by revenue. See which landing pages and trial emails come before payment, not just clicks.
4. Approve suggested changes. Kratly suggests budget shifts and fixes. You approve them, and each change is logged and reversible.

If you're not ready to sign up, the free wasted-spend checker shows where Google Ads budget goes to searches that never buy.
