Brilliant service with responsive team

We worked with Leafr to identify high-quality ecologists to support large scale remote surveys in the Mozaic platform. Leafr was brilliant across the board:
- The Leafr platform was easy to use (especially after their latest udpate)
- The Leafr team super responsive and they went out of their way to help with profile selection and outreach.
- The continuous support and check-ins were also very valuable and took away a lot of the 'contracting & invoicing' burden from us.

Would strongly recommend!

I’d been relying on my personal network…

I’d been relying on my personal network for consultant recommendations for years. It's easy to think "oh I know someone who does that" but truthfully, they weren't the right person for the job. The results were hit-and-miss and it was taking ages to make progress.

With Leafr, it was a completely different experience. Within days, I had three perfectly matched experts, and the one I hired was far better than any of the personal referrals I’d been chasing down.

No more polite calls with a guilty feeling of needing to hire a friend of a friend. Just the right person, fast. It’s the first time I’ve felt 100% confident in a consultant hire.

Finished 2 great projects with innovative and super engaged clients. The platform connected me to projects that would have taken me 5x more time to get.
Fast payment and the Leafr team is very quick on responding to any questions. Would 100% recommend to any sustainability professional/freelanced that wants to broaden their scope of clients and projects.

Leafr connected me with an incredible opportunity to lead the content strategy of a major private investment firm's ESG report - a dream project for me. Everything on the platform went smoothly. I'd recommend Leafr to any sustainability specialists or any company looking to hire one; they have the cream of the crop on the platform.

Makes finding sustainability specialists easy!

Leafr makes finding and working with sustainability specialists easy. The platform was exceptionally easy to navigate, and the Leafr team was supportive throughout; we had a great experience overall. I would recommend Leafr to anyone who is looking to streamline their search for sustainability expertise & work with highly qualified candidates.

Its so great

I have been so impressed with Leafr. It's made finding side hustle gigs and finally, I don't have to work with the bigger platforms that don't accommodate my niche!

The opportunities presented there are super and I am so pleased I joined. I just regret it took me so long to find it. All the missed opportunities!!!

Incredible Platform for Freelancers!

Leafr has made finding side gigs for freelancers incredibly convenient. Their process of vetting suitable top-tier professionals ensures that the freelancers on the platform know what they work on. As a registered freelancer on the platform, the access to resources and opportunities is brilliant. I wasn't aware of the plethora of freelance projects and niches in the Climate Tech and Consulting space until I joined Leafr.

Exceptional Experience

We have just completed our first hire & project via Leafr. Utilising a tool like the Leafr platform is a step change for our business, but the end to end experience has been outstanding. From the initial consultancy & onboarding, to the breadth and quality of talent available (we staffed our project 2 x consultants with excellent experience), to the ongoing management & transparency. Sustainability impact measurement & reporting has been a real pain point, I'm so glad we found Leafr & its exceptional team. Thanks guys, until the next project!
