Client Testimonial Video: One Tree Planted

Rachel, Director of Philanthropy at One Tree Planted, shares her experience working with Mainspring in a new testimonial video


Mainspring Agency is honoured to have played a part in the incredible journey of One Tree Planted, a global leader in reforestation efforts. From 2018 to 2023, our ongoing partnership spanned five transformative years, during which we supported the organization’s explosive growth, from $300,000 in revenue to over $50 million annually. Through a combination of strategic video production and brand development, we helped establish a strong foundation for their storytelling efforts and donor engagement.


A Partnership Rooted in Growth

When One Tree Planted approached us in 2018, they were a small but ambitious nonprofit with a clear mission: to make it easier for individuals and businesses to support reforestation. Over the years, we worked closely with their team to craft a compelling brand narrative, deliver high-quality branded content, and establish a scalable video production strategy that grew alongside the organization.

Rachel, Director of Philanthropy, reflected on the impact of our collaboration:

“Mainspring played a pivotal role in helping us tell our story and connect with our audience. Their videos weren’t just creative—they were instrumental in growing our brand and engaging our donors.”


Leveraging Video to Drive Results

A key element of our partnership was producing impactful testimonial videos, fundraising campaigns, and branded content that resonated with donors. From documenting large-scale reforestation efforts in British Columbia, Canada, to developing TV commercials, our videos helped establish One Tree Planted as a trusted and inspiring force in environmental activism.

One of the most powerful pieces was a video highlighting 'The Andes Project'. Combining stunning visuals with an emotionally resonant narrative, the video became a cornerstone of One Tree Planted’s fundraising efforts. As Rachel shared:

“In 2022, One Tree Planted had a first-time donor commit a million dollars, stating the reason they wanted to get involved was the Andes video. Overall, working with Mainspring has not only built the brand and voice of One Tree Planted, but has provided an authentic and impactful way for us to tell stories to a global audience and inevitably has helped us raise millions of dollars for reforestation.”


Building a Brand Through Video Storytelling

Beyond individual projects, our role extended to helping One Tree Planted develop their in-house video production capabilities. We guided their team in scaling their efforts, ensuring that as the organization grew, their storytelling continued to reflect their mission and values. Through workshops, creative development, and hands-on collaboration, we empowered their internal team to sustain the momentum we built together.


A Legacy of Success

The impact of our partnership is clear. By combining strategic video production with powerful storytelling, we helped grow One Tree Planted into a globally recognized nonprofit. Our videos weren’t just tools for engagement, they became the driving force behind a $50M annual revenue organization, fostering deeper connections with donors and stakeholders alike.


Rachel summed up the relationship perfectly:

“Mainspring wasn’t just a partner; they were an integral part of our success. Their ability to merge creativity with strategy helped us become the organization we are today.”


Why Testimonial Videos Matter
