Referred customers are our highest quality signups, but the channel is small. Referred signups convert to paid at 25%, about 10 times the 2.6% trial baseline. Most stay: 84 to 92% of referred converts still pay today. The channel adds about 4 paying customers a month, around 1.4% of new paid customers.
We raised the US reward from $300 to $1,000 on 1 July 2026. There is one day of data, so we cannot measure its effect yet.
The $1,000 reward replaced the $300 US reward on 1 July 2026. Only the automated drip email carries the new amount so far. The announcement emails to about 5,900 US admins and staff are still drafts.
There is also an instrumentation gap. Referral events do not record country. To compare the US ($1,000) with other regions ($300), we must join referral events to signup location data.
We suggest a checkpoint at the end of July on 3 measures: workspaces sending invites, invites per referrer, and referred signups. The $300 reward never lifted send volume, so volume response is the main unknown.
Counts are events, not unique people, except workspaces sending. The joined and activated steps only exist since 12 and 25 May 2026, so they undercount the 90 day window.
Workspaces sent 136 to 263 invites a month all year. Opens spiked to 1,099 in October 2025, but signups only reached 42 that month. Invites rose to 245 in May 2026 around the relaunch, then fell back to 194 in June. Referred signups did not follow: 24 in May, 13 in June.
| Month | Opens | Invites sent | Referred signups |
|---|
Admins account for 95% of paid workspaces that referred. Only 35 staff members sent an invite all year. Staff are the largest untapped audience. Whether staff can even open the referrals page is an open question with engineering.
| Referrer role | Paid workspaces referring | Share | Invites sent |
|---|---|---|---|
| Admin or owner | 753 | 95% | 1,800 |
| Staff | 35 | 4% | 101 |
| Contact | 1 | 0% | 1 |
A further 110 non-paying workspaces sent 226 invites. The adoption denominator is approximate: 777 referring paid workspaces against a paid base of 3,600 to 4,800, so 16 to 21%.
The median referrer sends one invite. The mean is 2.5. A small tail of 26 workspaces sent 10 or more. Getting one-time referrers to send a second invite is a bigger pool than finding new referrers.
857 workspaces sent at least one invite in the past year, including non-paying workspaces.
202 people signed up through a referral link in the past year. 51 of them started paying, all after their referral signup. That is 25%, against a 2.6% trial to paid baseline. The median time from signup to first subscription is 67 days.
Retention is strong. 8 of the 51 have a cancellation event, which puts retention at 84%. The current subscription flag says 47 of 51 still pay, which puts it at 92%. The truth sits between the two, because some cancellations were trial cancellations or were followed by a resubscribe.
One caveat: this is correlation, not proof the reward causes the quality. Referred signups choose us because someone they trust recommended us. Proving the reward adds customers we would not otherwise get needs a holdout test.
Five events cover the referral funnel. The two server side events are new, so conversion telemetry only starts in May 2026.
