The Short Answer

Freemium gets you more users. A free trial gets you more paying customers per signup.

Which one wins for you depends on three things: how fast your product proves its value, what each free user costs you, and how you want the market to see you.

This choice can shape your marketing, your brand and your whole business, so it shouldn't be taken lightly. Below are the trade-offs, the benchmarks, and the less obvious models in between.

Freemium, Free Trial and Reverse Trial: The Definitions

Two trial details change the dynamics a lot:

• Opt-in or opt-out. An opt-in trial asks for no card, so users decide to pay at the end. An opt-out trial takes a card at signup and charges unless the user cancels. Leadpages, for example, collects a card at checkout and charges on day 7.
• Length. Trials often run 7 or 14 days. The right length is the time a busy buyer needs to reach real value, not a round number.

Freemium: The Double-Edged Sword

When you start a SaaS, nobody knows you. Asking early adopters for money feels awkward, so many founders give the product away until they feel ready to charge.

Early on, that can make sense. Your first users are helping you fix bugs and shape the product, and their time is a fair trade.

At first, freemium looks great, especially if no competitor is free yet:

• People sign up, use the product and report bugs, so your feedback loop is short.
• Word of mouth starts, and articles mention you as the free alternative.
• Traffic and signups go up and to the right, with (hopefully) some paying customers.

But freemium is like a credit card. It's fun until the bill arrives. Here's what the bill looks like:

The upside is real: freemium can bring mentions, press and users you would never get otherwise. Still, it's a gamble, especially if you're not funded.

With funding, the gamble is safer. You can burn cash until you build paid-only features strong enough to pull people into paying.

Free Trials: Pressure, Good and Bad

A trial asks more of the buyer than freemium does. Early on, unless your product solves a common problem in a way people haven't seen before, few visitors will start one.

The reason is time. Successful B2B people are busy, and a trial gives them a deadline to learn a new product on top of their regular job.

Many will think "I'm swamped this week, maybe another time" and leave. So your page has to promise value fast, and the product has to deliver it fast.

What makes a trial work:

• A fast first session. Help users set up something on day one that gives them a reason to come back.
• Hands-on onboarding for early trials. When you only get a few, treat every trial like a future early adopter.
• Follow-ups that teach. If someone stalls, useful emails and product updates can bring them back. Just don't expect quick revenue from them.

In return, you don't have free users filling your support queue or steering your roadmap.

You may also earn more. People who like the product have to pay to keep using it, while a freemium user can stay on the free plan forever.

What the Numbers Say

In 2023, Kyle Poyar and Lenny Rachitsky collected free-to-paid conversion data from more than 1,000 products. Their benchmarks:

Free-to-paid conversion. Source: Lenny's Newsletter, "What is a good free-to-paid conversion rate?", August 2023.

The spread matters too. In the same data, a fifth of freemium products converted below 2.5%, compared with only 7% of free-trial products.

Kyle Poyar adds the other side: freemium products convert more website visitors into signups, while free-trial products often convert 2–3x more of their free users into paying customers.

So don't compare conversion rates on their own. A high signup count can be a vanity metric. Compare revenue per visitor instead:

Beyond Freemium and Free Trial: Five More Models

Freemium and free trials are the two most popular options. But there are at least five more.

1. Neither: demo first, pay to use

You can see the product in a demo or a video, but you can't use it until you pay. This is how we started Altosight.

It signals confidence: the company stands fully behind the value it delivers. Scarcity can also raise perceived value, as Robert Cialdini describes in Influence: The Psychology of Persuasion.

The downsides:

• It's very hard to make work unless your product clearly beats the alternatives.
• It builds no goodwill with people who can't afford it, or who want to try it before reviewing it.
• If the product doesn't live up to the promise, word spreads fast.

2. Both: a free version plus a trial of the paid plan

Users get a free version, sometimes without even registering, plus a trial of the premium tier.

BuzzSumo worked this way in 2015. You could search instantly for free, register for more, and trial the paid version for 14 days.

When the product is great, this creates huge goodwill. Bloggers recommended BuzzSumo because it helped their readers for free, and recommending a free tool never looks pushy.

That's growth built into the product itself.

The cost: you leave short-term cash on the table while the word spreads.

3. Freemium first, then trial only

Some companies start free to win early traction and press, then switch to trial-only to make more money. Others switch because the numbers stop working.

Hubstaff is a well-documented case. Co-founder Dave Nevogt explained why their "Free Forever" plan for up to three users didn't work, and how they replaced it with a one-user lite plan plus a 14-day free trial.

Expect friction. Closing free accounts creates backlash, and articles that recommended you as free may drop their links.

If the choice is that or closing shop, though, it's an easy call.

4. The reverse trial

New users start on a time-limited trial of the paid features. When it ends, they buy or drop to a free plan instead of losing access, as Kyle Poyar defines it.

Airtable, which Poyar calls an early pioneer of the model, upgrades every new account's first workspace to a 14-day trial of its Team plan. Afterwards, users stay on the Free plan or upgrade.

The idea is to combine freemium's signups with a trial's urgency. People get used to the premium features, and losing them hurts more than never having them.

5. The usage-capped trial

The trial runs for a set time and covers a small, real slice of the job. It suits products where every account takes real work, data or computing power to run.

It's the model we use at Altosight today.

The 2015 Examples, Ten Years On

I first wrote this guide in 2015. Here's how the companies I used as examples run their model today:

"Today" column from each company's own pricing page or homepage, checked October 2026.

All five now offer a free trial, including three that offered neither a free plan nor a trial back then.

The lesson from the original guide still holds: you don't have to marry your model. If it stops serving you, sit down with your team and change course.

How to Choose

Start from how your product delivers value and what each free account costs you:

If you go freemium, decide carefully where the free plan ends. In 2022, Airtable's then head of growth, Lauryn Isford, told TechCrunch to start with an 80:20 rule: draw the line where roughly 80% of users stay on their plan and 20% want to upgrade.

The Bottom Line

There's no universally right answer. Freemium buys reach, a trial buys revenue per signup, and the hybrids sit in between.

Pick the model that fits how fast your product proves itself and what each free user costs you. Then judge it on revenue per visitor, not conversion rate alone, and change course when the numbers say so.
