Stellar® is an open-source whole-system architecture that offers leaders a frame for the design of strategies that are both aligned with an enterprise's unique value-creation capability, and optimally adapted to our world of complexity. Stellar® is an instrument and process that is in successful use within many companies around the world, from the smallest start-up to major multi-nationals.

Stellar® was independently developed - it was not originated within, attached to or dependent on any university, institution or other organisation. The core frame of Stellar® was co-developed by Angus Jenkinson and Richard Leachman in 2002, and in 2004 they were joined by Kathelijne Drenth who co-created the further refinement of the frame and then led the development of content and process. Stellar® is open source, available for all to use free of charge and without obligation. It is not a brand, nor is the use of its trademark or logo licensed in any way (even to its founders). If anyone has been offered any licence or authorised use of the trademark or logo, please contact Stellar Ltd.

Stellar Ltd was formed to own the trademark Stellar® on behalf of all future practitioners, with the purpose of preventing others from preventing practitioners using the name 'Stellar'. It defends the trademark where necessary to safeguard the spirit and practice of open-source, and to prevent claims of ownership or exclusivity. Stellar Ltd's directors are Richard Leachman and Kathelijne Drenth. Stellar Ltd no longer accredits or certifies practitioners of Stellar® - accreditation or certification in the practice of Stellar® is now the responsibility of those consultancies which offer their own trainings in Stellar®. So far more than fifty consultants have been trained in Stellar®.

The majority shareholding in Stellar Ltd is owned by the Stellar Trust, a non-profit-distributing company committed to the interests of users of Stellar® and whose trustees are Richard Leachman and Kathelijne Drenth (see Angus Jenkinson owns a minority shareholding (see
