Off the Grid Ventures (OTG) is a San Francisco-based seed-stage venture capital firm founded in 2016 by Christopher Haire, David Mes, Mat Peyron, and Olivier Poissonnier. The firm built its thesis around a persistent funding gap in venture: women and foreign or immigrant founders receive a disproportionately small share of venture dollars despite data showing comparable or superior returns. OTG exists to back 'off the grid' entrepreneurs — underrepresented founders with cross-border perspectives — at the pre-seed and seed stages, with a particular focus on enterprise tech, specifically B2B SaaS and enterprise applications, and fintech.

OTG's four founding partners bring a deliberately cross-border perspective — European entrepreneurs operating in the San Francisco market — giving the firm firsthand understanding of the challenges immigrant founders face in accessing US venture capital. The fund's mission is to expand the definition of who receives institutional backing at the earliest and most consequential stage of company formation.

The firm is led by General Partner Gyula Feher, co-founder of Ustream, which was acquired by IBM in Hungary's largest-ever startup M&A transaction, alongside Partner Vera Pistyur and a team of operator-investors with deep connections to US and Western European tier-one VCs. Oktogon's first deal in 2019 was co-invested alongside Ashton Kutcher's Sound Ventures, establishing the firm's transatlantic positioning from launch. Oktogon backs founders with 'zero to one' potential building products with global appeal from day one. Investment criteria include EUR 10,000-plus in monthly recurring revenue, a technology-heavy business, and the capacity for extraordinary growth.

Olima Ventures is a New York-based early-stage venture capital firm founded in 2009 by Vijay Pandurangan, an engineer-entrepreneur-investor whose operating background includes senior engineering leadership at Twitter and the founding of Ephla Bio, a biotech company developing therapeutics targeting B-cell pathologies. Olima's thesis is to invest early in great teams creating a 'frictionless future,' concentrating in biotech, B2B software, enterprise technology, distributed systems, machine learning, privacy and security, and remote collaboration. The firm also leads biotech incubations directly, reflecting Pandurangan's scientific depth alongside his technology background. Olima writes checks ranging from $100,000 to $5 million with a sweet spot around $1.5 million, covering pre-seed, seed, and Series A stages. Across more than 15 years of deployment the firm has built a portfolio of approximately 68 companies.

Other notable positions include SpaceX, Candid — a dental aligners company — and Dieta, which was acquired by Cylinder Health in March 2025. The firm operates with a lean team of two to ten professionals. Olima's founder-operator profile is central to its value proposition: Pandurangan's own experience building at Twitter and in biotech gives the firm informed judgment on both the technical and commercial dimensions of early-stage companies. The combination of software and biotech competency under one roof is unusual at the pre-seed and seed stages and allows Olima to serve a broader range of founder types than most comparably-sized funds.

OM2 is an Israeli venture-builder and fintech-focused venture capital firm founded in 2010 and based in Herzliya Pituach, Israel's corporate-venture belt. The firm was co-founded by Dudi Peles, Oded Katz, who also serves as Acting CFO, and Uzi Gabsi, with Daniel Ben Yehuda serving as CEO of OM2 Holdings.
