Omnea

omnea.co
Omnea is a SaaS company focused on improving how organisations buy and manage third party spend. From its positioning, the product appears to sit in the procurement and finance operations space, helping teams bring more structure and visibility to purchasing workflows that are often scattered across email, spreadsheets, and disconnected tools. The core problem it addresses is the friction and risk that comes from ad hoc buying, unclear approvals, and limited oversight of suppliers and costs, especially as a company grows and spend becomes harder to control.
