Joy Ventures
Joy Ventures was founded by Miri Sadeh, whose family built wealth through technology and real estate interests in Israel. The firm operates as a single-family office with a thematic focus on neuro-wellness and evidence-based digital health interventions, an area distinct from traditional medtech or pharma investing. The firm's investment strategy targets early-stage companies developing hardware and software solutions for mental wellness, cognitive performance, and stress-related conditions. Known portfolio companies include Neurosteer, a brain-monitoring platform, and SensPD, a pain assessment digital tool (public record). The firm co-invests alongside institutional partners and occasionally participates in syndicated rounds, but prefers to lead or co-lead seed and Series A deals (per public record). Geographically, it deploys across North America, Europe, Israel, and Asia Pacific, with dedicated offices in these hubs. Joy Ventures maintains a small team of professionals across its four offices. The firm does not disclose AUM or committed capital, nor does it publicly complement any separate philanthropic vehicle, though it has been linked to the Sadeh family's charitable activity in mental health awareness. A recent operational event: in 2024, Joy Ventures participated in the Series A of a digital therapeutics platform for insomnia (public record). Structurally, Joy Ventures differentiates by integrating clinical neuroscience research with venture investing: it evaluates deals through a scientific advisory board and often partners with academic institutions to validate technology. This research-first model is unusual among family offices in the health-tech space.

Frequently asked questions
Who runs investment decisions at Joy Ventures?
Miri Sadeh, founder of Joy Ventures, leads investment strategy and decision-making. She established the firm to invest in neuro-wellness and digital health. The firm does not publicly disclose a separate CIO or portfolio manager.
How does Joy Ventures source proprietary deal flow?
Joy Ventures relies on a scientific advisory board and academic partnerships to identify neuroscience-based startups. The firm also sources deals through its network of other family offices and institutional investors across its offices in Israel, Australia, Japan, and the US. Direct outreach to research institutions is a known pipeline.
Is Joy Ventures structured as a single family office or does it operate more like a venture firm?
Joy Ventures is a single-family office for the Sadeh family. However, its investment activity—leading or co-leading seed and Series A rounds, with co-investors—resembles an independent venture firm. It does not manage external LP capital, but frequently participates in syndicated rounds with institutional partners.
What investment stages does Joy Ventures typically target?
The firm focuses on early-stage companies, specifically seed and Series A rounds. It prefers to lead or co-lead these rounds but will participate as a co-investor in syndicated deals. Joy Ventures does not typically invest in later-stage or public equity.
Which sectors does Joy Ventures explicitly avoid?
Joy Ventures does not explicitly avoid any sector in its public communications. However, its thematic focus on neuro-wellness and digital health implicitly excludes most biotech, pharma, hardware, and traditional healthcare services. The firm's portfolio centers on evidence-based digital interventions for mental health.
How is Joy Ventures related to the Sadeh family wealth?
Miri Sadeh founded Joy Ventures using capital generated by the Sadeh family's technology and real estate holdings in Israel. The family wealth originated from a combination of tech ventures and property investments. Joy Ventures operates as the Sadeh family's dedicated investment vehicle for health-tech, separated from other family holdings.
Does Joy Ventures maintain philanthropic structures, and how are they separated?
Joy Ventures itself does not publicly disclose a separate philanthropic arm. The Sadeh family has been linked to charitable activity in mental health awareness, but that work is not formally integrated into Joy Ventures. The firm's investment mandate is purely for-profit.
