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.

STL is leveraging its deep sector expertise as a venture builder to unlock the true value of innovation. Working alongside a network of investors and service providers, its strategic commercialisation process helps its customers build IP-led businesses that are viable and sustainable. It does this by applying streamlined entrepreneurial capabilities, in-house engineering and end-to-end due diligence for ventures bringing new technologies to life from basic concept to prototype demonstration, enhancing their growth and scalability.

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.

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.




Lifecare is committed to improving the lives of people and pets with diabetes. It is developing the next-generation of miniaturized and implantable nanobiosensors for correct and continuous monitoring of glucose and other biomarkers to the market. The company’s spin-off entity Lifecare Chemistry Ltd was founded to enhance research collaboration and secure ownership of its improved analyte-specific chemical receptor developments.

Anaphite is decarbonising battery production by accelerating the electric vehicle (EV) industry’s shift to dry battery electrode coating. Its technology platform solves the challenges of dry mixing and manufactures film-forming dry powders called Dry Coating Precursor (DCP®). This process enables cell manufacturers to reduce their energy use by up to 30% and create better, more sustainable batteries at lower cost.

NuNano is advancing the field of atomic force microscopy with high-precision probes for nanometer-scale imaging. Its proprietary microfabrication processes produce reliable, high-quality probes with market-leading dimensional tolerances. It also provides dedicated support to its customers, from probe selection to storage, for a seamless user experience.




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.

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.

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.
