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 newest Bristol incubator.

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.

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.

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.




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.

Dimension Biotechnologies is addressing unmet global vascular health challenges by improving diagnostic tools. Its transformative technology non-invasively monitors microscopic blood vessels at the biochemical level enabling doctors, drug developers and scientists to rapidly assess microvascular health and disease.




Celltris is reimagining battery cell design to unlock fast charging for heavy electric vehicles. Its mechanical approach to cell terminal design enables battery packs to be built at a 40% reduction in component costs with a 60% cut in heat generation. This enables industrial vehicles to be charged 2-3x faster without the thermal penalty, removing the need for oversized cooling systems or bottlenecks from slow charge times.

Extracellular is developing cell culture technologies to use the cell samples of living animals and plants to create sustainable alternatives to commercial products in the cosmetic, material and food industries. As a bioprocessing and manufacturing partner, it provides solutions from cell-line and scale-up development to facilitating routes to market, supporting other biotech companies seeking to develop greener consumer products such as cultivated meat, dairy products, leather, cotton and active ingredients for cosmetics.

Reach Industries is optimising lab and scientist efficiency with its Lumi™ visual intelligence platform. By automating data capture and analysis for experiments, observations and complex scientific workflows, the platform functions as a streamlined operating system that is accelerating R&D, improving compliance and increasing reproducibility.
