What are Tokens?
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: Participant Tokens document.
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.
Pricing:
Current Pay-As-You-Go prices are shown here:
Discounts:
We offer discounts on the standard Pay-As-You-Go rate for bulk-purchasing tokens. So if you are planning to collect data from over 1000 people please contact us.
You may also be able to claim half price tokens through Match Funding. Match Funding Tokens are our way of saying thank you for doing things that help us out - referring a friend or colleague, helping us diagnose a bug, or participating in a promotion. They effectively give you 50% off the price of tokens. Learn more here.
Our lowest token rate is only available to Universities purchasing for a whole department. See next section for details.
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, 80% of this cost is electricity consumption. 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.
What types of subscriptions are there?
We offer different types of subscription:
Optional Add-ons:
How do I buy a departmental licence
Contact us for a quote letting us know which subscription type you would like (Pay-As-You-Go, Metered, Unlimited) and how many accounts and tokens you expect to need.
Lab prices start at £1,200 + VAT. Department prices start at £2,000 + VAT.
Who is the Subscription Administrator?
The Subscription Administrator is the person within your department (usually a technician) who has control of who is on the subscription.
They can add people to the subscription at any time. This means that only people authorised to use the subscription benefit from your departmental subscription, and if someone has been missed out by accident, changes can be made in-house.
How can I be added to my department's subscription?
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, 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.
Do I have to use a university email address to be added to my department’s subscription?
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.
Can I collaborate with someone outside my university?
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!
How do I request tokens?
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 How To: Participant Tokens Guide.
How do I transfer a project ownership to another user?
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.
Due Diligence
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.
