Thames Valley SME 100 Growth Index 2022

The annual Thames Valley SME Growth 100 index recognises and promotes the region’s high-growth small and medium-sized enterprises, and is ranked by year on year growth.

To be included in the listing, businesses need to be based in the Thames Valley and to have grown their turnover significantly in the past year. The listing only includes independent, privately-owned companies, headquartered in the region, with a turnover of no more than £20m.

The 2022 edition of the Thames Valley SME Growth 100 index is sponsored by law firm Herrington Carmichael, commercial property consultants Hicks Baker and audit, tax, advisory and risk firm Crowe UK

This year, more than half of the listing’s top 100 companies are newcomers, demonstrating the impressive growth that so many businesses have managed to achieve, particularly with so many newcomers appearing toward the top of the listing.

Top of the index this year is Oxford BioTherapeutics with a substantial growth of 154.5%. Based in Abingdon, this clinical stage oncology company has made great progress in the development of immunotherapies for cancer, focusing on ‘first-in-class immune therapies’ that aim to improve the outcomes for patients.

Though new to the listing, Porthaven Group, based in Windsor, takes second place. An independent company, this group specialises in building and operating ‘market leading care homes’ that offer ‘exceptional surroundings’, fine dining, and dementia care.

In third place is the Winnersh-based FullCircl, previously on the listing as Artesian Solutions, supporting businesses with customer lifecycle intelligence that will help to engage with customers to keep them on for life, encouraging its clients to ‘own the market’.

Despite being another newcomer, UK Land Group takes fourth place and exhibits the highest turnover statistics in the listing’s top 5. Based in Hungerford, this company owns properties throughout the UK and specialises in the acquisition of ‘privately and publicly owned property companies’ as well as venturing into land where there are perceived ‘medium to long term’ opportunities.

Fifth place is filled by yet another newcomer – The Hartley Wintney-based IMSL (Industrial Microbiological Services) provides a testing and consultancy service that specialises in the microbiology of materials. IMSL is customer and service driven, producing claims that are supported by ‘fully robust, scientifically and statistically sound data’.

The Business Magazine congratulates all the companies that qualified for this year’s TV SME Growth 100 Index.

SME 100 Growth Award (below £10m)

Winner: FullCircl

“A lot of organisations were interested in buying us but then I had a call with a CEO at another company who I knew and we talked about working together as our businesses are complementary. So, one plus one equalled three. We have extended our value proposition for both sets of customers; we can cross-sell, upsell and focus on customer retention, as well as customer expansion and growth. We used the Entrepreneurial Operating System to bring the businesses together with a common vision and collective core values. There may be future acquisitions and we are also really excited about strategic partnerships we are working on, including with Google.” Andrew Yates, CEO

Judge’s comments: “Another very strong category, with those short-listed having a minimum of 15% growth during the qualifying period, which in a ‘normal’ year would be excellent, but with Covid-19 and Brexit headwinds thrown in makes it even more impressive. Our winner grew by an amazing 115% during the qualifying period and has grown since, too. Throw in an acquisition and a rebranding, and it has been a very busy past year or two for them.”

SME 100 Growth Award (above £10m)

Winner: Square Health

“Covid-19 had a big impact on the acceleration in adapting digital healthcare. It allowed us to mobilise huge amounts of resources across the UK and deploy them in areas of need. The UK has had to reinvent the delivery of healthcare and this was an open door for us. A catalyst was in people being able to access GPs when practices were closed and there have also been growing areas of healthcare provision, such as mental health services for younger people. We have been more-or-less doubling our year-on-year revenue. Our staff are the most critical part of the business and we have a culture of working hard, promoting teamwork and supporting each other.” Dr Bippon Vinayak, Co-founder and Monisha Vinayak, Commercial Director

Judges’ comments: “One of the fastest growing companies in our list, they have continued the rapid level of growth over the last year. By leveraging technology, they have quickly built solutions that complement and expand more traditional healthcare models. Their clear and focused vision and long-term client commitments suggest that we are only seeing the start of their success.”

Resilience Award

Winner: Shorts Group

“We are always diversifying our business and the Covid-19 pandemic led us to add more services, like the provision of portable toilets and staff welfare offerings. We jumped into this market and growth here continues. We listen to our customers and our people as we expand. One of our biggest challenges is recruiting and retaining staff as skip and plant hire, along with waste collection, is a very hands-on business. One way we do this is through the apprenticeship scheme we set up six years ago. We also maintain strong links with our community, for example, with local rugby clubs. Many of our employees’ children play sports and we feel it is important to support the next generation. It’s an approach that is in the DNA of our family-owned business.” Gary Short, Owner, and David Guest, Finance Director

Judges’ comments: “A strong owner-managed family business, who have successfully grown and diversified their operations since the pandemic, while maintaining very strong links to each of the local communities in which they operate. They have overcome both internal and external challenges to refine and maintain their core business, while also developing multiple new service lines to complement their customer offering.”

Tech Company of the Year

Winner: Oxford BioTherapeutics

“Our business is about identifying new ways to tackle cancer and working with major pharmaceutical companies to develop therapies. We use a lot of technology in our approach, including mass spectrometry and analytical biochemistry. What drives the company is the passion we all have for what we do. We are striving for the same thing: to help cancer patients who don’t have other methods of treatment available to them.” Ben Thomas, Senior Director, and Lindsey Hudson, Director of Business Development & Partnership Alliance

Judges’ comments: “An exemplary business in its field, specialising in immunotherapies for cancer, with significant rates of success and continued business growth in recent years, they scored highly across several award categories. Their advancements in using technology to innovate ‘T cell therapies’, harnessing immune cells to help cure cancer, are industry leading and quite remarkable.”

Workforce of the Year

Winner: Bridewell Consulting

“For us, it is always about getting the right quality of people. We have focused a lot on building our internal talent recruitment team that constantly maps out the best cybersecurity talent in the UK. When we interview people, if they are not quite right for us at the time, we keep in touch so if a role opens up we can bring them in. We focus a lot on learning and development, and we also recruit people who are ex-armed forces or on career transitions. We developed our company values in consultation with our staff and we all try to live by them.” Anthony Young and Scott Nicholson, Co-founders

Judge’s comments: “This was an incredibly strong category. Our winner has experienced a period of particularly rapid growth, hiring 15 people a month to now be a 200+ employee organisation. It was clear that the company values of ‘do the right thing’, ‘one team’ and ‘going above and beyond’ are key elements during the recruitment process and beyond, and it was this that gave our winner the edge.”

Owner-managed Business of the Year

Winner: Craft Buddy

“I had worked for our father’s arts and craft business that imported goods from India and Gary had worked for a DIY chain where he gained experience sourcing products from China. We combined our knowledge to establish Craft Buddy. Our licenced product ranges with major brands began almost by accident when Disney visited our stand at a trade fair in Birmingham in 2020. We retail through a range of channels, including online, direct to consumers, to trade and distributors, and through TV shopping. We aim to continue on the same growth trajectory as we build the brand and get in front of more consumers.” Dino and Gary Wadhwani, Co-founders

Judges’ comments: “A strong group of family and owner-managed businesses made judging very difficult. Our winner impressed with their passion and commitment in a challenging sector. Their pragmatic and timely strategies alongside a genuine bootstrapped approach is an ideal lesson in how to navigate the myriad channels of retail. What was started by two brothers in their aunt’s house is now winning new customers in over 30 countries with their innovative brand and licence portfolio.”
