Dona E.

Grant Manager

“For grants management, the system is inclusive as your entire team uses the platform and sees each new action or transaction in the workflow.”

Dona E.

Grant Manager

“Nothing sticks out - perhaps the backend could be a bit cleaner in terms of naming data that is used to pull in reporting information.”

Becca A.

Philanthropy Director

Pros

“The platform makes it significantly easier and faster for our team to create new projects, track submissions, and manage workflows.”

Margo S.

Director of Creative Strategies and Arts-Based Initiatives

“Submittable representatives were extremely thorough and helpful in guiding us in how to create an application (in our case, for a Fellowship program) in Submittable and use different kinds of forms within the platform.”

Leila M.

Senior Program Manager

“Submittable also provides improved data access and reporting tools that help us evaluate impact and make stronger decisions.”

Margo S.

Director of Creative Strategies and Arts-Based Initiatives

Cons

“For admin users, the Admin Panel is much less clean and simple an experience than the grantee, reviewer, or even employee views.”

Jessalyn P.

Sr. Grants Manager

“My own learning curve made me hesitant about asking for help with minor updates and fixes. ”

Dona E.

Grant Manager

“Our clients say they cannot read all of the questions we have on applications.”

Terry M.

Allocation and Grant Coordinator

Cons

“The messaging component can glitch, as I've sent messages to people who did not get them sent to their inbox, and vice versa. Since I communicate with applicants primarily through messages, it can be frustrating to find that messages were not delivered.”

Maggie M.

Program Manager

“It is difficult to identify a time and this causes missing submissions sometimes.”

Akif K.

Electrical-Electronics Engineer

“We've found the email's generated by Submittable have formatting issues and are often blocked by anti-spam software, so there have been some deliverability issues and some problems with reading the system-generated emails.”

Barby B.
