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.
Our Old Market incubator is currently full, but if you if you are looking for private lab space we encourage you to get in touch to enquire about future openings, 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.
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.
CellVoyant is accelerating the development of novel stem cell-based therapies for chronic diseases. Its technology uses AI-first live cell imaging to predict and optimise stem cell differentiation, enable advanced cell analytics and ultimately unlock the controllable manufacturing of any cell and tissue in the body at scale. Built on foundational research at the University of Bristol, CellVoyant works at the intersection of cell biology, computing, engineering and machine learning to carry out its mission.
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.
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.

Folium Science is increasing agricultural productivity by enhancing animal welfare and feed efficiency in livestock farming while reducing environmental impact. Its unique CRISPR-Cas technology platform harnesses natural biological systems to safely modulate animal microbiomes by regulating metabolic functions and targeting unwanted bacteria with extreme precision. This approach helps reduce reliance on antibiotics and can be applied to both plants and soil to improve their bacterial biomes for optimal growing conditions.
Kelpi is tackling plastic pollution by developing sustainable alternatives to single-use plastic packaging. It uses seaweed to create a unique bioplastic coating that provides a world-leading water barrier for new-generation packaging while being recyclable, biodegradable, and low carbon. By working with major food and drink, cosmetics and home care brands, Kelpi is already reducing reliance on fossil-fuel plastics and paving the way for a greener future in these industries.
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.
