During the first two months of the corona pandemic, researchers at the Department of Clinical Microbiology at Umeå University developed a sensitive test of SARS-CoV-2 antibodies, to determine whether a person had covid-19. In May 2020, the antibody test was validated for clinical use in Region Västerbotten, Sweden. This was the start of the company Xerum, which was part of Umeå Biotech Incubator from 2020 to 2023.

Julia Wigren Byström, for how many years did Xerum work with the incubator team?

“For three years, 2020 to 2023, during the Pre-incubator phase and the Verify phase.”

What happened to your idea in the end?

“The company is still operating, but in a less active state compared to the corona pandemic period. With support from UBI, we have explored the market opportunities to develop antibody tests for other relevant infections using at-home sampling.”

What did you most appreciate about the incubator environment at UBI?

“We have got valuable guidance on how to do the right things in the right order, which was crucial for us. We started our company in the middle of the pandemic, so acting quickly to commercialize our product was essential. The innovation advice, business coaching, financial support, and access to labs were key factors in getting the company this far.”

What learnings have you taken with you from your journey in the incubator?

“I have gained so many skills during this time! Mostly related to business development, such as conducting needs and market analysis, developing IP strategies, understanding health economics, and navigating regulatory landscapes, etc. I also learned the importance of building a strong team with complementary expertise and collaborating with others in other areas to create added value.”

What would you say to others wanting to utilise a research idea?

“It takes time to learn everything involved in running a business. It helps if one person in the team takes on the role of entrepreneur and drives the business idea forward. Make use of the innovation system in Umeå. Have fun, stay curious, and be prepared to tackle challenges!”
