What is a reverse trial?
A reverse trial gives new users a time-limited trial of your paid features, then moves them to a free plan if they don't buy. Kyle Poyar, who writes the Growth Unhinged newsletter, puts it this way in Your guide to reverse trials: at the end of the trial, users can either buy or downgrade to a fully free tier. The guide was first published on 29 June 2022 and republished on growthunhinged.com on 23 April 2026.
The guide is built around an interview with Lauryn Isford, then Airtable's Head of Growth. In 2022, Isford described Airtable's setup as a 14-day free trial of its Pro Plan, its top self-serve tier, after which users who don't upgrade default to the Free Plan. That describes Airtable at the time of the interview; check Airtable's current plans before you copy it.
Poyar's 2026 conversion report sorts self-serve entry points into five models. The descriptions below are the report's own:
| Model | What a new user gets |
|---|---|
| Free trial | Time-limited access to the full product |
| Freemium | A free tier with usage or feature limits |
| Reverse trial | Temporary access to premium features on a free plan |
| Interactive demo | A guided hands-on product experience with dummy data |
| Paid trial | Time-limited access with a special introductory price |
What did the 2026 free-to-paid conversion report measure?
It measured how many free signups become paying customers within six months. Poyar ran the survey with ChartMogul and ProductLed in January 2026 and published the 2026 free-to-paid conversion report on 4 February 2026 (free to read with a newsletter sign-up). ChartMogul hosts the full report openly, with its method. The headline facts:
- Sample: 200 software products. A typical respondent had $1 million to $10 million in annual recurring revenue, $50 to $249 a month in revenue per customer, and 25% to 50% yearly growth. 34% had under $1 million ARR, and 22% were mostly B2C or a B2C and B2B hybrid.
- Definition: free-to-paid conversion is the share of leads or free signups that become paying customers within six months.
- Method: a Typeform survey shared by email, Slack and social media. Respondents were asked to estimate roughly what share of their leads or free signups pay within six months, so the rates are their own estimates, and the report says some charts may rest on fewer than 200 answers.
- Entry points: 57% of products lead with a free trial, 26% with freemium, 7% with a reverse trial, 7% with an interactive demo and 4% with a paid trial.
- Trial setup: 20% of free-trial products require a credit card up front. The most common length is 14 days (62% of trial products), followed by 7 days and 30 days (14% each).
- Median: 8% free-to-paid across all products, though Poyar notes very few products actually convert at 8%.
The spread is wide. Among free-trial products, 20% convert below 2.5% and 23% convert above 25%.
How does a reverse trial convert compared with other models?
In the report's benchmarks, reverse trials sit between free trials and freemium, and far below trials that require a card. The report's chart labels the 50th percentile "good" and the 75th percentile "great":
| Model (2026 report) | How common | Good (50th percentile) | Great (75th percentile) |
|---|---|---|---|
| Free trial, credit card required | 20% of free-trial products | 25% to 35% | 50% to 60% |
| Free trial, no credit card | 80% of free-trial products | 4% to 6% | 10% to 15% |
| Reverse trial | 7% of all products | 4% to 6% | 8% to 12% |
| Freemium, regular signup | 26% of all products are freemium | 3% to 5% | 8% to 12% |
| Freemium, try before creating an account | 38% of freemium products | 7% to 9% | 8% to 12% |
Read the reverse-trial row with care. Poyar writes that the reverse-trial sample was relatively small and that its difference from the other models is not statistically significant. 7% of 200 products is about 14 products, so treat the row as a rough direction.
The card-required row is the outlier. The report says free trials that require a card see 30% free-to-paid conversion, which Poyar calls more than 5x the trials that don't require one. That number needs the next section's context before you act on it.
Why can a higher conversion rate still mean fewer customers?
Because each model loses people at a different step. The report follows 1,000 website visitors through each model:
| Per 1,000 visitors | Free signups | Visit to signup | Paying customers | Free to paid |
|---|---|---|---|---|
| All freemium | 90 | 9% | 5 | 5.5% |
| Freemium, try before account | 70 | 7% | 5.6 | 8% |
| All free trials | 45 | 4.5% | 3.6 | 8% |
| Credit-card-required trial | 35 | 3.5% | 10.5 | 30% |
The report gives no visitor path for reverse trials. On these figures, free trials convert signups at a higher rate than freemium overall (8% against 5.5%) but end with fewer paying customers per 1,000 visitors (3.6 against 5), because freemium gets twice the signups. Poyar's conclusion is that freemium versus free trial is an outdated question: if your goal is adoption, you're likely better off opening the product up, and if your goal is conversion, likely better off asking for a card. Poyar adds that a card requirement could blunt signups unless the product warrants the friction, and points to Canva, which tells people starting a Canva Pro trial that they'll get a reminder 7 days before it ends.
The 2026 data also softens an older rule of thumb. The 2022 reverse-trials guide said free trials often see 2 to 3 times the free-to-paid conversion of freemium. The 2026 survey found free trials convert at only slightly higher rates than freemium, and that the difference disappears once signup rates are counted.
When does a reverse trial make sense?
When you care about long-term users as much as fast revenue, and your paid plan is worth buying on its own. Those are the two conditions Isford gave in the 2022 Airtable interview:
- A user-growth goal. Isford said a reverse trial works well when you are most focused on user growth, because users who don't buy stay on the free plan, which keeps the door open to convert them later.
- A compelling reason to convert later. Isford said a reverse trial only works well when there is a compelling reason to convert later, and that its impact is capped if the paid plans aren't compelling in their own right. Packaging, meaning which features sit in which plan, is the foundation.
Isford's packaging advice, as given in 2022:
- Free: features that drive top-of-funnel user growth. In Isford's Airtable example, inviting many colleagues to a view you built should be free.
- Paid: moat features (high switching costs or network effects), sticky features (use more, pay more) and sophistication features (deeper, more complex use). In the same example, Airtable's Salesforce integration is well suited to a paid plan.
- The line: draw it where roughly 80% of users stay on the plan they have and 20% want to upgrade.
The 2026 report points the same way. Poyar writes that teams should "stop copying another company's free model without understanding what it optimizes for" and gives three questions to answer first: do you want more people to use the product or more people to buy it; when do users reach the moment the product clicks; and what does each free user really cost you.
Which trial model fits a small B2B product?
Match the model to how fast buyers see value and what a free user costs you. The table is our reading of the 2026 report and the 2022 Airtable interview; neither source gives this as a rule.
| If this describes your product | Start with | What the sources say | Watch |
|---|---|---|---|
| Buyers see value in the first session and you need revenue soon | Credit-card-required trial | 30% free to paid, but 35 signups per 1,000 visitors against 45 for free trials overall | Refunds and trial cancellations; send a reminder before the trial ends |
| Value needs setup, data or teammates and takes longer than 14 days | Reverse trial | Isford: works when the focus is user growth and the paid plan is compelling | How many free users come back and upgrade |
| Every free user costs real money (AI usage, data, onboarding time) | Time-limited free trial | Poyar asks what real cost you incur for every free user | Cost per trial against revenue per conversion |
| The product spreads through invites and shared work | Freemium or reverse trial | Freemium gets 90 signups per 1,000 visitors; Isford's 2022 Airtable example says inviting colleagues to a view should be free | Invites sent per new account |
| High price or a long, hands-on setup | Interactive demo or a sales-assisted trial | 7% of products lead with an interactive demo; 80% of free-trial products add human touchpoints for enterprise users | Demo to paid rate |
| You don't know yet | No-card free trial, 14 days | The most common setup: 57% lead with a free trial, 80% of those skip the card, and 62% run 14 days | Your own six-month free-to-paid rate |
Our advice: pick the row that fits best, run it long enough to measure six-month conversion for your first cohorts, and change one thing at a time.
How to choose and test your trial model this week
Measure your own baseline the way the report does, then make one change. These steps are our suggestion.
Answer Poyar's three questions
Write one line each: adoption or revenue first, when users reach the moment the product clicks, and your cost per free user. If you can't answer the cost question, work it out before you add a free plan.
Calculate your baseline
Take everyone who signed up six to twelve months ago and count how many paid within six months. That matches the report's definition, so you can compare yourself with the bands above.
Try a dual offer before a full switch
In the report's follow-up post, published 18 March 2026, one survey participant described adding a second homepage button for a 14-day card-required premium trial next to the free start, and reported a 26% improvement in premium trials created. It is one self-reported example, but it tests demand for a card-required trial without removing your current path.
Add a human touchpoint
80% of free-trial products in the survey have human touchpoints when an enterprise user starts a trial. On a small team, the founder can send each trial signup that fits your customer profile a short personal note in the first two days. Our guide on how to qualify a lead fast helps decide who gets one.
Write down what competitors offer
List each competitor's entry point (free trial, freemium, reverse trial or demo), trial length and whether it asks for a card. Siela's Competitor Watch sends a briefing every Monday morning on what each competitor launched, priced, hired or posted, with links, so you can see when a rival changes its pricing.
Frequently asked questions
What is the difference between a reverse trial and freemium?
Freemium starts every user on a free tier with usage or feature limits. A reverse trial starts new users on the paid features for a set time, then moves them to the free tier if they don't buy. In Kyle Poyar's 2026 survey of 200 software products, 26% led with freemium and 7% with a reverse trial.
How many software companies use a reverse trial?
Few. In the 2026 free-to-paid conversion report from Kyle Poyar, ChartMogul and ProductLed, based on a January 2026 survey of 200 software products, 7% used a reverse trial as the main way new customers start. Free trials led at 57%, followed by freemium at 26%, interactive demos at 7% and paid trials at 4%.
What is a good conversion rate for a reverse trial?
The 2026 report, built on survey respondents' own estimates, puts a good free-to-paid rate for reverse trials at 4% to 6% and a great rate at 8% to 12%, where good is the 50th percentile and great the 75th. Conversion means paying within six months of signup. Kyle Poyar notes the reverse-trial sample was relatively small and the difference from other models is not statistically significant.
Does requiring a credit card for a free trial increase conversion?
In the 2026 report it came with a higher conversion rate and fewer signups. Card-required trials converted 30% of signups to paid, against 8% for free trials overall. Per 1,000 visitors, card-required trials got 35 signups and 10.5 paying customers, while free trials got 45 signups and 3.6 paying customers. Kyle Poyar warns the card can blunt signups unless the product warrants it.
How long should a reverse trial last?
Neither Kyle Poyar's 2026 report nor the 2022 reverse-trials guide sets a reverse-trial length. Airtable's reverse trial, as its Head of Growth described it in 2022, gave new users 14 days of the Pro Plan before moving them to the Free Plan. Across all free-trial products in the 2026 report, 14 days was the most common length (62%), followed by 7 and 30 days (14% each).
