To make Gorilla as accessible as possible at any level of budget, use of the Gorilla software is free and we only charge for access to the data collected. In this way, anyone can sign up for an account and collaborate with another user - at no cost. Students - who typically collect data from only a few participants - can use Gorilla cheaply. And researchers - who typically collect more data - pay a bit more for the same service.
The way we control access to the data collected is via Participant Tokens. You need to purchase one Token for each participant you intend to collect data from. Rejected participants will not consume tokens, as tokens are only consumed when they enter a Finish Node. Find out more in our How To: Participants guide and Pricing FAQ documents.
Note: Gorilla is not a participant recruitment service. If you wish to recruit participants through a recruitment service, you must arrange and pay for this through the recruitment service. Participant recruitment is a whole separate business to creating easy-to-use tool for experiment design - we leave this to the specialists! To find out more, check out our How To: Recruitment Policies Guide.
Current Pay-As-You-Go prices are shown here:
You can earn free tokens via our Referral Scheme! Every time you refer a friend or colleague to Gorilla, each of you will receive 20 free tokens. These essentially give you a 50% discount on future purchases. You can find out more about free tokens here.
Why do you charge per participant?
We incur very real costs each time a participant completes an experiment. We pay server fees and database fees. On top of this, we like to pay our staff a salary for the work they do. This covers the costs of the support desk and continued development of Gorilla.
Per participant pricing seems like the fairest approach, as it allows students to use Gorilla cheaply. For large well funded projects that typically use online recruitment services, the Gorilla fees are only a small addition to the participant fees.
We offer different types of subscription:
To learn about renewing your subscription see our Renewals page.
If you have any questions or want to chat about the best subscription for you, just send us an email at email@example.com.
You can now purchase subscriptions via the Gorilla website! You'll find the link to do this on your My Account page.
If you'd prefer us to issue you a quote or invoice in advance of payment, email us at firstname.lastname@example.org and we'll be able to organise this for you.
You can find your subscription status through 'My Account'.
If your department has a subscription, you will not need to pay per participant. If you think your department may have a subscription, check our list of institutions with subscriptions here.
If you think you should be on a subscription, please contact your department's Subscription Administrator, whose details can also be found on this page. If your subscription administrator is not listed, please contact us to be added to the subscription.
The Subscription Administrator is the person within your department (usually a technician) who has control of who is on the subscription.
They can add and remove people from the subscription at any time. This means that only people authorised to use the subscription benefit from your subscription.
On a metered departmental subscription, subscription administrators are also able to control token usage through a token request system.
Yes! Go here!
For the most part, yes. This ensures that your subscription is only being used by the right people.
However, in exceptional circumstances and with our approval, we allow you to add others to your subscription. Be aware that these members will be able to use your department tokens.
If you are entitled to be added to your department's subscription, you may have already been added to your subscription. You can check your subscription status through 'My Account'.
If you have not been added to your department's subscription, and you have been given an enrolment code by your university, you can enter this from 'My Account'.
If you have not been added to your department's subscription, and you do not have an enrolment code, please contact your department's subscription administrator, whose details can be found on this page. If your subscription administrator is not listed, please contact us to be added to the subscription.
Yes – you can collaborate with any Gorilla user anywhere in the world. And together you can choose whether or not to use tokens from your departmental subscription.
By default in Gorilla only the project owner can change recruitment policies and assign tokens. The project owner is the person that create the project folder in Gorilla. So, if Nick Hodges from Gorilla University adds Jo to a project, the tokens come from Nick (or his subscription). If Jo Evershed from Cauldron Institute adds Nick to one of her projects, the tokens come from Jo (or her subscription).
This prevents other researchers from running up a bill for their own projects at your department’s expense!
If your department is on a metered subscription, you will need to request tokens. Your department will set a limit on the number of tokens that can be granted to each user automatically upon request, and any further requests will have to be approved by your Subscription Administrator. The workflow for this is built into Gorilla so that it is as easy and efficient as possible.
For more details see the Pricing FAQ page.
A seat is the same as a user. If you have 10 seats on your subscription, that means you can have up to 10 users accessing your subscription.
It’s easy for the Gorilla support desk to transfer projects between users. So, if you’ve already created a project before your department buys a licence, and your collaborator is the project owner, Gorilla Support can transfer ownership of the project between users.
Universities often have internal due diligence processes that must be followed to allow procurement to proceed. All the information required can be found from this Due Diligence page.
