R-Squared Advisors

Roy Erez and Roy Rubin, the firm's co-founders, make all investment decisions jointly. Both are former CEOs who built and sold companies before establishing R-Squared, and the firm highlights this dual-operator governance as its core structure. There is no investment committee beyond the two partners.

The firm's primary sourcing engine is its LP network, composed of over 80 leading technology founders, executives, and venture capitalists. This network operates as both a referral channel and a diligence resource, giving the firm early visibility into enterprise and SMB companies, particularly in the US and Israel. The partners' own operator backgrounds also generate direct founder-to-founder introductions.

Based on its disclosed activity, R-Squared exclusively executes direct equity investments, participating in seed through growth-stage rounds ranging from roughly $3 million to over $60 million in syndication. The firm has not disclosed any fund-of-funds commitments or allocations to external venture managers.

The firm does not publish a formal exclusions list. Its stated focus covers enterprise and SMB SaaS, AI, vertical-specific technologies (including TaxTech, LegalTech, and InsureTech), fintech, marketplaces, and e-commerce enablement. Smaller allocations exist in B2C, gaming, and AgTech, suggesting R-Squared avoids heavy industrial, hard-asset, and deep infrastructure verticals.

R-Squared operates as an asset manager structured more like a founder-led angel fund than a traditional venture firm. It does not function as a family office — its capital derives from an 80-plus LP base of operators and VCs rather than a single family balance sheet. The firm's model borrows from angel-network speed and culture while deploying institutional-grade check sizes through co-investment rounds.

The firm markets itself as a hands-on partner that provides strategic, go-to-market, and product guidance drawn from the partners' own CEO experience. Portfolio founders consistently describe the relationship as akin to adding co-founders, with frequent operational support and introductions rather than passive monitoring. The network of LPs also creates follow-on engagement opportunities for portfolio companies.

The portfolio shows a concentrated footprint in the United States and Israel, consistent with the firm's Burlingame headquarters and the partners' networks. A smaller number of investments target Africa and the Middle East, such as HAAT, a last-mile delivery marketplace for underserved regions, backed alongside NFX and other strategic investors.
