Tŷ Cornerstone
Tŷ Cornerstone was founded by a foster carer and national health and social care professional, frustrated by the gap between what carers are asked to do, what they need to do, and the tools they're actually given. Everything we build comes from lived experience and is shaped by carers who are in it right now, because the best solutions come from the people closest to the problem.
HIRAETH - FOR FOSTER CARERS AND PROSPECTIVE ADOPTERS
A daily diary app built by a foster carer, for foster carers. Quick to use, built on a robust and defensible recording framework, and exportable as a PDF to share with your supervising social worker. Supports foster carers caring for children, those on parent and child arrangements, and families on an early permanence journey.

cynefin - for shared lives carers
A daily diary app built specifically for Shared Lives carers. The same robust, defensible recording framework as Hiraeth, adapted for the Shared Lives model. Cynefin was born from a direct request by a foster carer and Shared Lives carer who beta tested Hiraeth and, drawing on her own experience of meticulous record-keeping, saw an opportunity to give newer carers a stronger foundation and to make excellent practice even more accessible for everyone.

ABOUT TŶ CORNERSTONE
Tŷ Cornerstone was founded by a foster carer and national health and social care professional who got tired of watching carers do extraordinary work without the tools to support it. With a background spanning frontline fostering, operational leadership, and service development across health and social care, every resource we build is grounded in both lived experience and professional knowledge. We're based in Wales, and proud of it.
