For over five years, Xist4’s local knowledge and IT pedigree have helped us fill specialist roles in remote locations with thoroughly qualified, on-brief candidates. Gozie is friendly, approachable and prioritises our vacancies, and we are pleased to recommend Xist4 for IT hiring.
Numatic International have been working with XIST4 IT Recruitment for over 5 years. We selected XIST4 because of their local knowledge, their expertise in successfully filing highly specialist IT vacancies in remote locations and of course their IT Recruitment pedigree.
Without exception XIST4 has provided us with strong applicants that match our exacting requirements from a technical and interpersonal point of view. It is refreshing to work with an agency that performs recruitment in the proper manner, they qualify applicants thoroughly before forwarding their CV only providing candidates that are worthy of consideration and they do not empty their entire database in our inbox.
Gozie is my point of contact, and he is always friendly and approachable. I know when we give him and his team a vacancy to work on, that they will prioritise filling it.
It gives me great pleasure recommending them to other organisations looking for IT related staff and I look forward to a long term relationship with them.

We have worked closely with Xist4 to recruit some critical technical IT Infrastructure and Development roles in a very challenging marketplace. We have been successful in now appointing all of the roles – Gozie Ezulike has provided a very professional level of service and expertise.
CIO – National Charity Museum
Xist4’s thorough pre-analysis and filtering meant our team saw only on-brief candidates, and their clear grasp of our technical requirements kept everyone well prepared throughout a lengthy process. The result was the successful appointment of both a Development Manager and a Product Manager, and we would readily recommend their services.
I am writing to thank you for your hard work in finding Development and Product Manager candidates recently that lead to the appointment of both these positions.
Unlike other recruitment consultants I have worked with you have been able (and willing) to do a great deal of pre-analysis and filtering that has minimised the workload for our team. I particularly noticed the ease with which you understood our technical requirements but also how clearly you communicated with both us and your candidates, making sure that everyone was properly prepared for our lengthy interviewing process.
I would have no reluctance to recommend XIST4 services to any organisation wanting to recruit technical staff.

HR Manager – Hebron
Xist4 were responsive, professional and a pleasure to work with, using their IT expertise and rigorous technical screening to present only candidates who met the brief. We secured an outstanding Group ICT Manager quickly and efficiently, and would gladly use and recommend Xist4 again.
When Sanctus were seeking to hire a group ICT Manager XIST4 IT Recruitment were recommended and we have not been disappointed. From the initial contact through to post-placement follow-up Gozie and his team have been highly responsive, professional and a pleasure to work with.
The process we employed was designed to utilise XIST4 IT sector expertise and to minimise the recruitment duration. The technical screening undertaken by XIST4 IT ensured that the candidates interviewed all met the role requirements and had been assessed for appropriate competencies. This allowed us to select an outstanding candidate based on best fit for our organisation.
XIST4 provided us with an efficient route to an excellent new member of our team. I would not hesitate to use XIST4 again or recommend them to others.
Operations Director – Sanctus
We needed a rapid, culture-fit hire who combined technical competence, operational experience and strong partner management to keep our global systems robust and member-focused. Xist4 delivered, and the appointee is already adding real value and moving multiple initiatives forward.
As the global professional body for an emerging discipline we rely on our IT systems and partners to achieve our objectives. To support our corporate and individual members, disseminate knowledge, host exams and reach new audiences across the world we need to be confident that our systems are robust and suppliers delivering. Our Technical Services Manager has the dual responsibilities of managing internal office IT and ensuring our suppliers deliver.
Xist4 were given a brief to identify technical competence, operational experience and partnership working. Character and approach to work were also really important to the organisation as we maintain an open, friendly and member focused culture. The real challenge with the brief however, was the turn-around time to ensure sufficient handover. We are delighted with the result of the search and the appointee is adding considerable value and allowing us to progress a number of fronts.
COO – IAM
IRM had a great experience with Xist4: Gozie proactively clarified our requirements, sent only relevant CVs and ensured every interviewee was properly briefed. The candidate quality was outstanding, and the hardest part was choosing just one.
IRM have had a very positive experience working with Xist4. Gozie was very proactive
in making sure that our requirements were understood, which meant that all the CV's sent to us were
relevant, saving us time and effort. He also made certain that all interviewees were briefed properly.
All the candidates we interviewed were of very high quality and the only difficulty was in narrowing
the choice down to one.
Financial Controller & HR Manager – IRM
Xist4’s transparent screening made it easy to compare strengths, and they delivered a diverse, on-profile slate for our Software Developer role. Gozie was responsive and never pushy, and the top two of our final four came from Xist4; we would happily recommend them.
XIST4 were able to find several very suitable candidates for our software developer position recently. Their candidate screening process was transparent and provided questions which enabled us to very quickly see the strengths and weaknesses of each candidate.
Candidates came from a wide spread of education, experience and region so we felt that we did not miss out on suitable applicants.
Our agent, Gozie, was available when we needed him and arranged contact with candidates quickly and efficiently, he was never pushy or requiring constant attention like so many recruiters, always polite and fast to respond.
The top 2 candidates out of a shortlist of 4 came from XIST4. I would certainly recommend XIST4 for IT and Software Development recruitment.
Thanks, especially to Gozie.
Operations Manager – Cel UK
In a short time, Xist4 delivered high-calibre engineering hires who are already growing with us, thanks to a process that truly understood our needs. Gozie’s team is responsive, reliable, and easy to work with, and we look forward to building on the partnership.
We have only been using XIST4 for a short period of time. However, during this period they have been able to provide us with high calibre engineering employees who are now growing within our organisation. The process of finding and understanding what we require truly sets XIST4 apart. Gozie and his team are always available to answer any questions at any given time making them a very reliable recruitment firm. We hope to continue and build on our relationship with XIST4.
HR Director – POWA
Referred by a trusted partner after wasting time elsewhere, Xist4 quickly understood our brief and delivered quality candidates fast, even posting the advert within hours. Professional throughout the interviews and offer stage; we will use them again and strongly recommend them.
We were referred to Gozie through a trusted business partner after wasting time with other firms.

The Xist4 team quickly summarised our requirements and posted the advert within hours of discussing them and acting very professional throughout the entire interview and offer process.

Group CIO – B&H Worldwide
Launching our Bristol office from the US, we needed fast, safe hires; Xist4 delivered pre-interviewed, screened CVs within 24 hours and kept the quality high throughout. Within two weeks we were spoilt for choice and confidently made our selections, and we highly recommend them for complex remote hiring.
Globanet recently opened a European division in Bristol, UK. Being a company primarily based in the United States, it was critical to ensure that we hired the right staff for our European office, efficiently and safely. XIST4 were able to meet our challenge and within 24 hours of engaging, we had CV’s in our hands – with the applicants having been pre-interviewed, screened and checked before being sent to us.
Having used XIST4 in previous companies, I knew that XIST4 were going to be able to stretch to recruiting for our remote office without issue – and I was not disappointed. Within 2 weeks and 4-5 CV’s, which had been pre-screened and interviewed by XIST4, we were spoilt for choice with candidates and had a difficult time selecting just a limited number from the selection provided!
I have no hesitation in recommending XIST4 for recruitment – however vast your recruiting challenge.
Senior Director – Globanet
Xist4 took the time to truly understand our bespoke senior leadership brief, shaping the role with us and aligning on culture as well as technical fit. The candidate quality was outstanding, we made a superb hire, and we look forward to partnering with Xist4 again.
We worked with Xist4 to fill a challenging senior leadership role with very bespoke requirements.
Gozie took the time to fully understand what we were looking for and helped us to define our needs also. He got to know not just what we do as a business but what we stand for and what our culture is like so he could ensure a good fit personally as well as technically.

MD -n.able
Xist4’s Executive Search solved our lack of time and market reach, truly understood our brief, and delivered strong candidates from near and far while keeping us updated each week. We made the hire within seven weeks and would not go back to our old approach.
One Big Circle would highly recommend Xist4’s Executive Search service. Before we approached Xist4 in relation to our key hire, we were experiencing our usual challenges; lack of time to directly engage in the market ourselves, expertise to identify the best candidates and awareness that skills we were looking for were in short supply.
We met with Xist4, and they understood us and knew first-hand what we were going through, and although at times it felt like they were interviewing us they were able to get all the information they needed to recommend the right solution. Executive Search was a method that we had never used previously, as we were under the impression it was purely targeted at senior appointments.
It is fair to say that we would never go back to our previous method of recruitment. Within a short space of time, they had identified a number of candidates locally and from further afield, they kept us fully informed of their progress on a weekly basis and within 7 weeks we had made an appointment.
Director – One Big Circle
Our first experience with Xist4 was excellent: they prepared thoroughly, understood a new role in an unfamiliar industry, kept us on track with regular catch ups, and even gave us ATS access. Their commitment to diversity and Gozie’s responsive, reliable approach helped us find not just one but several outstanding candidates.
Our first experience using Xist4 was a very positive one. The role was a new one and in a different industry to what we normally recruit for. I was struck by the degree of preparation and professionalism in ensuring that there was a full understanding of our requirements. The whole process was well thought out – from scheduling regular catch ups, to guiding us through the candidates, to being able to access Xist4’s ATS system. Xist4’s commitment to diversity was evident through the mix of candidates presented to us. Gozie is responsive, adaptable, and reliable. He listens and takes on board feedback helping us to find not just one, but several, excellent candidates.
Head of People – Aperio Intelligence
For a fast-growth startup struggling to fill a complex role combining technical expertise, management experience and languages, Xist4 quickly delivered standout candidates and smoothly coordinated a multi-country interview process. We ended up choosing between two top talents and would recommend Xist4 for quality delivery, sharp selection advice and impeccable communication.
Our requirements as a fast growth startup are very specific and always challenging to meet in the highly competitive cloud computing market. We briefed Gozie on a particularly hard-to-fill position which combined technical knowledge, management experience and languages. This role had been opened for a few months with other recruitment agencies not delivering the quality of profiles we expected.
In a short space of time Gozie was able to present very strong candidates and facilitate a complex interview process with interviewers in different countries. We ended up in a position where it was a difficult decision to choose between 2 top talents Gozie had presented to us!
I would recommend Xist4 for the quality of their delivery, advice on candidates selection and impeccable communication throughout.
Head of Recruitment, EMEA – Box
As a FinTech start-up without a dedicated HR team, we needed a specialist who truly “gets it”. Xist4 matched both the technical and cultural brief, quickly placing two outstanding Quant Developers; we’ll be partnering with them again and highly recommend their work.
As a FinTech start-up business it has been important to us to partner with a specialist IT recruitment agency with experience of working with start-ups, and a true understanding of what we're looking for, both technically and culturally. We don't have time to waste, and we don't have a dedicated HR function. Xist4 IT Recruitment has proved that they "get it".
In a short space of time they managed to successfully place 2 highly talented Quant Developers into our team, and we look forward to working with them on future hires. We would highly recommend Xist4 IT Recruitment to companies like us, who value talent, communication and results.
CTO – Essentia Analytics
Xist4 nailed the brief, running an inclusive search that broadened our thinking and zeroed in on the right profile for our flagship product’s training and adoption framework. We hired Amanda, she is already adding real value, and we would happily recommend Xist4 to any company looking to diversify with exceptional talent.
We asked xist4 to help us search for a talented professional to design, create and deploy the training and adoption framework for our flagship product. To be successful, we needed to approach user adoption in a way that challenged our traditional lines of thinking. So, with the recruitment for this role, we felt it important to bring in a more diverse range of insights and perspectives. We felt that this could be best achieved by recruiting from a more diverse pool of candidates.
Xist4 really understood the brief and helped us hone in on the profile/skills/experience match that would be most successful for this critical role. Xist4’s inclusive search approach and process were well thought out and thorough. We successfully hired Amanda, who has been a great addition to the team. I have no hesitation recommending Xist4’s search services to any company looking to diversify its workforce with exceptional talent.
