We have been working with Zeren to aid in our global expansion and Thibault has helped us with the onboarding of two key hires. One was a Regional Sales Director for UK/I and the other one was a Regional Sales Director South EMEA; which are both new territories for our business. Zeren delivered a very strong pipeline for both roles throughout the search, backing everything up with detailed search data, all whilst guiding us through the interview process and wider hiring journey. The profiles that we were looking to hire were very specific and unique to our market and Zeren understood exactly what we were looking for. The pipeline of candidates generated gave us the opportunity to challenge candidates and make sure we hired the right Regional Sales Directors to help us scale our EMEA business. We are extremely happy with the service provided by Zeren and look forward to maintaining our partnership with them as we continue to hire more people and grow in size.

Zeren was a fantastic partner in helping us hire our first VP Sales to scale and shape our commercial organisation. As an early stage seed funded but highly ambitious software business it was vital that we had access to the top talent in market and we were delighted with the pipeline that Zeren provided and the process we went through during the hiring stage. We have already recommended Zeren’s services to other high growth software companies and would absolutely use them again when we need to bring in additional hires at Machine Labs.

Joe and the ZEREN team did a great job managing our search for a new CTO. Joe did a great job identifying and presenting strong candidates and managing the process. We were able to fill the role with a strong candidate with relevant past experience in under 2 weeks! I would recommend working with Joe and plan to use him again when we have additional roles to fill.

Zeren described our hired candidate as our ‘unicorn’ and they were right – a uniquely complimentary mix of skills, motivation and experience. He has already had an impact in less than 2 weeks, and has settled in as if he has always been part of the team. Thank you to the Zeren team for a hugely successful outcome and a very efficient and effective process.

Zeren were our search partner for our recent VP Growth EMEA hire based in Berlin. It was a challenging brief, but they worked closely with us to define the scope of the search and to more clearly define our ideal candidate. The team conducted a thorough search, we had informative weekly updates, and they ultimately produced a strong shortlist of candidates. We really enjoyed working with the team at Zeren. We could not be happier with the result of the search, and would love to work with them again in the future.

Chris first approached me about a role that he felt I would be a good match for, a typical experience for most people on LinkedIn - but Chris really stood out as different. Chris and I spoke at length about the opportunity, and he was able to answer all of my questions and provide a lot of clarity. Chris provided a detailed presentation that clearly described the company, the role, and the challenges in a great level of depth - Chris had a very deep understanding of the company and the role that he was recruiting for. Chris was responsive, clear, and set expectations for both sides throughout the interview process. This engagement concluded with me being offered a fantastic opportunity to become a CTO in a fast growing scale-up company.

I cannot speak highly enough of my experience with Zeren. Oscar reached out to me about an exciting Berlin-based start-up working in the legal automation space and he immediately got my attention. Oscar talked me through the role and guided me through every step of the hiring process. Oscar and Zeren kept me in the loop the whole time, were quick to respond to questions and made the whole process a genuine pleasure. Now I am in the role, I am looking forward to working with Zeren to help me grow the team.

I collaborated with Paul and Zeren on a VP Product opportunity which ended up with me joining Akeneo. From our first interaction, Paul and the Zeren team created a casual but yet professional environment which made the whole process very smooth and easy. I especially appreciated Paul's thoughtful coaching and close follow-up through the many steps of the process. Highly recommended!

I've been in touch with Jennifer from Zeren for the past 6 months and I'm very pleased with our collaboration. Being the first time that I worked on executive consulting, Jennifer was really supportive and was able to guide me through the field with ease. I've been working with a client for the past 5 months through Zeren and everything is going great. By having weekly sessions with Jennifer we are able to tackle potential issues heads on. Really professional and hands on.

Thanks to Zeren I was able to join an amazing startup as Head of Engineering. He provided solid information about the opportunity along with valuable information about every step of the process, helping me prepare accordingly for every interview. I would recommend Zeren to anyone looking to work with someone who really cares about both sides of the process.

Having worked with recruiters both as a candidate and a hiring manager, what clearly made a difference with Zeren is that they made things as simple and clear as possible - which always helps build a relationship - and that they managed time and expectations in a respectful way for both myself (the candidate) and the company. The overall experience was a perfect match to the end result and landed me the role of Director of Data & Analytics in a well established and amazing business! Thank you Chris!

Chris has been instrumental in securing an incredibly high-level Senior Director of (Product) Engineering position with one of the best EnergyTech/ClimateTech businesses. The journey has been challenging, but Chris has made it a joy, he is both personable and professional, and I strongly believe I have built a strong relationship with Chris.

Zeren has a very robust and transparent method to get you over the finish line; clarity around salaries, documentation to prep for an interview (not only verbal) and most importantly; being super responsive and on the case. Going from initial conversation with an employer to signing the contract for a director level role was the fastest I've experienced in my career. A pleasure to work with.
