Nines

Family offices managing multiple residences typically juggle property details across spreadsheets, text chains, and disconnected file storage, creating operational gaps that staff turnover and complex principal schedules make worse. Nines is a household management platform built specifically for this environment, offering a centralized operating system for properties, physical assets, staff, vendors, documents, and maintenance schedules. It is used directly by family office executives, estate managers, and private service professionals who need a single system of record for everything happening across a principal’s residences.

A family office executive profiled on the site, Rebecca Maguire of EFO Advisory Services, used the platform after 20 years of testing comparable tools. Her assessment: it is the first software she found that reflects how estate management actually works, rather than adapting a generic business tool to a household context. The platform includes layered permissions so sensitive documents stay controlled when staff transitions occur, and a self-hosted deployment option is available for principals requiring data sovereignty.

Specific capabilities relevant to family office operations include:

• Multi-property management with property-specific zones, calendars, and task assignments
• Granular permissions that allow access to be granted and revoked per staff member or vendor
• Recurring task automation for maintenance schedules and household protocols
• Physical inventory tracking with photo documentation and asset records
• AI-powered suggestions and industry-standard templates built on Marta Perrone’s estate management methodology
• SOC 2 Type II certification and AWS-backed infrastructure

Nines positions itself as a tool for the operational side of household life, not investment or financial management. Family offices seeking a platform to consolidate financial reporting or portfolio oversight will need to look elsewhere. Pricing is not publicly disclosed, and the platform is most relevant to offices with active residential management needs across multiple properties.
