Founded in 2002 by managing director Mario Thomas, the firm provided web design, online retail and other software products to brands including Coca Cola, Aston Villa Football Club and Sock Shop.
Sue Laverick, financial director at Chapter Eight, confirmed the business ceased trading on January 9.
She said: “Unfortunately the board has taken steps today to put Chapter Eight into liquidation and will convene a meeting of creditors in due course.
“We have spent the day informing staff and clients of the decision. Creditors will be contacted once an administrator has been formally appointed.
“Our first priority has been informing our staff and ensuring they receive support.”
Members of the company’s technical team have formed a business that will continue to run clients’ websites in the short-term and has bought the necessary assets from the firm, Ms Laverick added.
A total of 18 staff have been made redundant by the company, which was based at The Basilica on King Charles Street.
