1ct.co (also associated with "1st Corporate Technology" / Gemstone Capital branding in Nordic listings) is a Denmark-based investment and company-building firm involved in venture investing, corporate finance, and active business development. The firm operates as a hybrid between a venture capital investor and a transaction/advisory platform, engaging in activities such as capital raising, mergers and acquisitions, IPO advisory, and strategic restructuring of companies. Its investment strategy focuses on identifying and developing "high-potential" technology and information/communication sector companies, with an emphasis on helping them scale toward market leadership in Nordic markets. Beyond capital deployment, it provides hands-on support including deal structuring, management consulting, and access to investor networks. The organization is positioned as an active investor-builder rather than a passive fund, combining investment activity with advisory and corporate finance execution.
