Our Old Market incubator hosts growing Deep Tech companies that have moved beyond proof of concept and are scaling their teams, typically 20–30 people strong.
This site serves as the main event venue of our Bristol campus — featuring the 1023 Bar, our community’s main stage for events and a gathering spot for informal meetups every Thursday.
Old Market members are breaking new ground in several science and engineering fields — from advanced sustainable materials to vaccine platforms and stem cell therapeutics.
With 30,000 sq ft of laboratory, office and meeting space, our Old Market incubator is a supportive, well-connected hub for growing Deep Tech companies.
This location also features a large event space, shared social spaces, and our favourite addition — the 1023 Bar, open every Thursday for the community.
Membership includes access to our platform of support, providing opportunities to attend workshops and events, connect with other founders, and find a mentor.





If you are looking for private lab and office space, get in touch to enquire about our current availability at Old Market or explore OMX, our third Bristol incubator, set to open in 2026.

Fine Agrochemicals is enhancing crop quality for fruit and flower growers in agricultural, ornamental and landscape markets using its plant growth regulator (PGR) technology. Its PGR products, made using naturally occurring molecules through fermentation and combined with chemically synthesised compounds, help stimulate plant cells to enhance nutrient levels and targeted growth for improved crop outputs.

Argonaute RNA is developing safe, reliable and targeted methods of temporarily silencing genes in different tissue cells. It does this via the proprietary modification of small interfering RNA (siRNA), using a novel stabilisation method to overcome previous obstacles to developing siRNA drugs for healthcare.

EnsiliTech is improving the shelf-life and global accessibility of vaccines and other biological therapeutics by combatting cold chain transport and storage issues. Its novel ensilication technology, designed for both existing and new biopharmaceutical formulations, encases thermally unstable biomolecules within silica nanoshells to prevent environmental degradation. This eliminates the need for cold chain requirements that are expensive, prone to failure and generate significant carbon dioxide emissions.

Zentraxa is precision engineering biomaterials, pushing the boundaries of biopolymer synthesis to develop sustainable, performance-enhancing ingredients for everyday products. Its proprietary technological platform (Zentide) overcomes the biodesign limits of existing, conventional peptide synthesis by designing, producing and testing complex, novel peptides with one universal process. Zentraxa creates bespoke solutions for a range of industries by combining key features from different naturally-occurring proteins, such as stiffness, adhesion or thermal stability.

Invivo Healthcare is developing solutions to better understand and modulate human microbiomes, promoting long-term wellness and a sustainable future of healthcare. Its supplement therapeutics are plant, nutrient and microorganism-based, designed to lead the way in combating the rise of chronic diseases and a reductionist approach to medicine.




Glaia is developing innovative solutions to optimise agricultural plant performance to help food security and fight climate change. Using disruptive technology, its sustainable agrochemicals unlock the potential of the photosynthetic process, enabling plant cells to more efficiently convert energy to biomass to increase crop yields without increasing inputs. This results in greater profits for growers and reduced greenhouse emissions, delivering more sustainable global food production.

Epinal is revolutionising the detection and prevention of narcotic-impaired behaviour for safer roads, flights and workplaces. Utilising AI and novel biotechnology that mimics natural sensory mechanisms, it’s developing a handheld breathalyser that generates rapid results with extreme sensitivity and selectivity.

Transdermal Diagnostics is pioneering the development of bio-wearables that enhance the prevention, diagnosis and management of chronic conditions like diabetes. Its unique sensing technology aims to create the world’s first needle-free continuous monitor for glucose and other health biomarkers. By analysing hair follicles, the adhesive skin patch and transmitter wirelessly communicate information straight to a smartphone app, facilitating a transformative shift in patient care and quality of life for those with diabetes.
