GrowSurf vs Prefinery Comparison 2026
GrowSurf runs an ongoing refer-a-friend program with automatic rewards and tax paperwork for the payouts, from $125 a month for up to 2,500 participants after a 14-day trial. Prefinery is narrower: a pre-launch waitlist where referring somebody moves your position up the queue, from $49 a month for 1,000 users, also with a 14-day trial. Pick GrowSurf when the reward is a real payout tracked for tax purposes. Pick Prefinery when the reward is simply moving up the list before launch.

GrowSurf
Referral programs priced by participant
GrowSurf runs a refer-a-friend program for a product rather than a one-off giveaway: every participant gets a link, the rewards fire automatically, and the tax paperwork on the payouts is handled. It bills on how many people are in the program rather than on how many you refer, which is unusual and worth understanding before you launch.
Our note
The pricing model is the thing to think hardest about: paying per participant is generous if your referrals convert and punishing if they do not. Run the trial with real traffic before committing to a year.

Prefinery
Waitlists where position moves on referrals
Prefinery runs the waitlist you put up before launch and gives every signup a queue position that improves when they bring somebody. That mechanic is the product, and the rest is the plumbing around it: the embedded form, the emails, the fraud checks and the export. It bills on how many people join.
Why people weigh these two
- Prefinery instead of GrowSurf
- Prefinery applies the referral mechanic to launch waitlists, where position moves as people refer, from $49 a month; GrowSurf suits the ongoing program after launch.
- GrowSurf instead of Prefinery
- GrowSurf runs referral programs generally rather than the queue-position mechanic built for a pre-launch waitlist specifically, priced by how many people take part.
Which one should you pick
Pick GrowSurf for a product that already has signups and wants referrals to keep paying rewards indefinitely. Startup is $125 a month for up to 2,500 participants, and every plan includes automatic rewards, 1099 tax filing and a REST API, after a 14-day trial that includes those paid features.
Pick Prefinery for a product that has not launched yet and wants the waitlist itself to spread. Lite is $49 a month for 1,000 users, with unlimited emails and full data export on the cheapest tier, and going over the cap costs half a cent per extra user rather than forcing an upgrade. If the plan is only to collect addresses, a plain email tool costs a tenth as much and does that alone.
Common questions
- Is Prefinery cheaper than GrowSurf?
- At the entry tier, yes: Prefinery's Lite plan is $49 a month for 1,000 users, against GrowSurf's $125 a month for up to 2,500 participants. Per person the gap narrows, since GrowSurf's cap is more than double the size for a bit over double the price.
- What happens if I go over my user limit on Prefinery?
- It costs half a cent per extra user per month rather than forcing an upgrade to the next tier. GrowSurf does not offer that middle ground: past 10,000 participants on Business, pricing moves to a quote.
- Does Prefinery pay out real rewards like GrowSurf does?
- Not in the same way. Prefinery's mechanic is queue position: referring somebody moves you up a waitlist. GrowSurf triggers automatic rewards, including gift cards through Tango Card, and files the 1099 tax forms the payouts create.
- Can I try both before paying?
- Yes. GrowSurf's 14-day trial includes its paid features, and Prefinery offers a 14-day trial on all three of its plans, from Lite through Pro.
