love working with us


“Love the Harness interface and how it integrates beautifully with our website.

They've regularly added or improved features, often in response to our direct requests. Admin is easy for non-techies to handle.”

Rose V.
Communications Manager
The Ministry Against the Death Penalty

“Harness is really user friendly. Anyone that uses a computer can figure it out quickly.

The dashboard basically does all the work for us!”

Pamela W.
Santa Fe Animal Shelter and Humane Society

“Getting millennials and Gen Z to give consistently is one of the biggest barriers in modern fundraising.

Harness breaks down those barriers. With Harness, it’s so simple that I believe we will convert check-writers to online donors.”

Carol D.
The Hope Pregnancy Center of Brazos Valley

“Our donors have several ways to make a donation. I like being able to text our donors directly through the app.

What I like most is the ability to provide the text-to-give option, campaigns, and Round Ups for our constituents.”

Boys & Girls Club Washington County

“Harness has allowed us to spontaneously capture donors through dedicated campaigns, social media and website platforms.

The elegance of integrations and presentation makes it look like we have a dedicated team of professionals running our digital marketing.”
