SigmaLabs
SigmaLabs is a multi-family office with headquarters in Palo Alto and additional offices in London, Ramat Gan, and New York. The firm's founding year and principals remain undisclosed in public sources, positioning it as a discreet capital allocator serving a network of wealthy families. The firm invests across technology sectors including enterprise software, artificial intelligence and machine learning, cybersecurity, fintech, digital health, and climate technology. SigmaLabs pursues a blend of direct investments and co-investments alongside institutional partners, spanning venture capital through growth equity stages. Its geographic reach spans North America, Europe, and Israel, with offices in each region enabling local deal sourcing and due diligence. The firm's portfolio includes companies such as Armis Security, a cybersecurity platform, and Cato Networks, a secure access service edge provider (per public record, 2021; per public record, 2019). Team size and total assets under management are not publicly disclosed. The firm maintains additional offices in London, Ramat Gan, and New York, suggesting a team structure that can evaluate opportunities across multiple time zones. SigmaLabs does not publicly operate philanthropic foundations or adjacent vehicles attributable to its name, though individual family clients may maintain their own structures. A structural differentiator is SigmaLabs' explicit multi-country office model — rare among family offices — which signals a deliberate strategy to source proprietary deal flow in three distinct innovation ecosystems. The firm's opacity around its principals and AUM also suggests a preference for relationship-driven capital deployment rather than public fundraising.

Frequently asked questions
Who runs investment decisions at SigmaLabs?
SigmaLabs does not publicly disclose its principals or investment committee. The firm's website and public records do not name a CEO, CIO, or founding partner. This level of anonymity is consistent with a discreet multi-family office model where key decision-makers operate outside the media.
How does SigmaLabs source proprietary deal flow?
SigmaLabs likely sources deal flow through its four-office network spanning Silicon Valley, London, Tel Aviv, and New York. The firm positions itself to access innovation hubs in technology venture capital — particularly Israel's cybersecurity and enterprise software ecosystem, Europe's fintech and climate tech clusters, and US-based AI/ML startups.
Is SigmaLabs structured as a single family office or does it operate more like a venture firm?
SigmaLabs describes itself as a multi-family office, meaning it manages capital for multiple wealthy families. It does not market itself as a venture capital firm or asset manager with commingled funds, though it structures direct investments and co-investments alongside institutional partners.
Does SigmaLabs participate in fund commitments or only direct deals?
Public information suggests SigmaLabs pursues both direct investments and co-investments. The firm has not disclosed fund commitments to external managers. Its structure as a multi-family office typically involves flexible deployment across direct positions and partnerships.
What investment stages does SigmaLabs typically target?
SigmaLabs invests across stages from early-stage venture to growth equity. Confirmed portfolio positions include companies like Armis Security (established 2015) and Cato Networks (founded 2015), both of which received late-stage capital. The firm's sector focus aligns with technology companies that have achieved product-market fit.
Where does the underlying wealth come from?
SigmaLabs does not publicly disclose the source of its underlying capital. As a multi-family office, it likely manages wealth for families whose fortunes originate from technology, real estate, or finance. Without public attribution, the specific family branches remain unknown.
Does SigmaLabs maintain philanthropic structures, and how are they separated?
SigmaLabs does not publicly operate a philanthropic foundation or charitable arm under its own name. Individual families within the office may maintain separate philanthropic vehicles, but the firm itself does not advertise such structures.
