Currently employing 66 staff, the business is already recruiting for ten sales and account management roles with more to follow.
And work has begun to create new space for up to 59 workers by renovating a previously derelict area of its Jewellery Quarter base.
It will also free up existing space within the building to accommodate growth of sister companies, IT services business Icomm Technologies and enterprise application provider Mercato Solutions.
Probrand's investment is being part-funded by a £100,000 grant from the European Regional Development Fund (ERDF) Land and Property programme. This initiative is managed by Birmingham City Council on behalf of the Department for Communities & Local Government.
Peter Robbins, managing director at Probrand, said: "We believe in upskilling and investing in a local workforce and facilities that nurture innovation for growth.
"We are now well positioned for our next stage of growth and this grant sends a clear message that the government is committed to supporting the knowledge-based economy on national and regional levels."
Tahir Ali, the city council's cabinet member for development skills and jobs, added: "The support offered to Probrand to refurbish a derelict area of its property, will enable business expansion and job creation in the technology sector. This is proof that the Property Assistance Programme is making a positive difference in the Jewellery Quarter."
