Background
Begin Capital is a seed-stage venture capital firm with offices in Europe and Israel, investing in B2B software companies at the earliest stages. The fund was founded with a focus on international founders building enterprise products, and backs companies across sectors including AI-enabled tooling, industrial automation, defence and robotics. Begin Capital's portfolio spans multiple European markets, with a consistent thesis around capital-efficient B2B software with clear paths to enterprise customers. Cheque sizes at seed are typically in the range of $1 million to $5 million.
In April 2026, Begin Capital co-invested in All3's $25 million seed round alongside RTP Global (lead), SuperSeed, s16vc and VNV Global. All3 builds agentic factories for defence, robotics and aerospace customers and is expanding into France, Germany and Ukraine . The All3 deal reflects Begin Capital's appetite for industrial AI and defence-adjacent automation that travels across European markets.
Begin Capital occupies a niche within the European seed ecosystem: international in portfolio composition but focused on B2B software fundamentals. Its participation in the All3 cap table alongside a mix of UK-based and international co-investors reflects how seed-stage syndicates for defence and industrial AI are forming across national boundaries in 2026.
