Precision Nutrition · UK / East Midlands & South Yorkshire
Nutrition, flavour, hospitality and brand — calibrated for executives and ambitious businesses across the East Midlands & South Yorkshire.
Ten voices. Every discipline, one business owner at a time.
Hospitality
Four weeks. That’s all it took to turn this business around. We went on to achieve a five-star accreditation, something I genuinely didn’t think was within reach when we started.
Flavour development
James’s technical expertise, attention to detail with complex documentation, and seamless coordination between our team and the master manufacturer have made every project a success.
Nutrition & wellbeing
His approach, knowledge, and guidance throughout my consultation were exemplary. The personalised nutrition plan and targeted support made a real difference to how I felt day to day.
Cannabinoid
He helped refine our vision from the ground up — reimagining our branding and logo, and formulating our products using purely natural, high-quality ingredients with zero synthetics. I couldn’t be happier with the results.
Compliance
He completely aligns with our mindset on strict regulatory compliance, and he’s been instrumental in connecting us with key manufacturers and managing those relationships smoothly.
Research & development
He quickly became the reliable leader we needed in R&D, allowing our business to continue its day to day operations without the disruption of managing development in house.
Brand & marketing
He completely elevated my brand identity, transformed my LinkedIn profile, and brought clarity and consistency to my social media presence.
Nicotine pouch R&D
The support from James was key for the success of the division, reducing development lead-time and improving the output with a portfolio of flavours loved by our customers.
Flavour development
He combines deep technical knowledge with a methodical, well structured development process, and he simply won’t settle until a profile is exactly right.
Flavour development
He has a sharp read on trends before they hit the mainstream, and a genuinely extensive network of contacts across the industry.
Every engagement behind these was scoped and capped in writing before any work began.
