According to the company's LinkedIn profile, the team currently consists of two employees operating in the technology, information, and internet industry. Its digital presence is managed via the website yoursliceof.com, while partnership enquiries are handled through the email address [email protected].

The funding documentation for this round was filed in June 2026 (following an allotment of shares that took place earlier the same month).
