Silicon Roundabout Ventures

Silicon Roundabout Ventures is a community-driven venture capital firm, providing pre-seed and seed capital to European deep tech startups. It targets fundamental companies across computing, defense, and energy, backing those led by pioneering scientists and engineers. The firm seeks deeply technical, infrastructural, defensible technologies with robust IP to define industry standards.

The venture firm was founded by Francesco Perticarari, formally established in August 2018. It evolved from the Silicon Roundabout community, initiated by Perticarari in 2011. His insight was to scale deep tech angel investing, leveraging the community's extensive network to discover early-stage technical talent.

Silicon Roundabout Ventures supports deeply technical founders across Europe building global-leading infrastructure technologies. It envisions a distinct financial institution merging venture capital, scientific expertise, and community integration. Its mission identifies exceptional technical founders, fostering disruptive advancements through early capital and guidance.

High-Level Overview

Silicon Roundabout Ventures is a community-driven venture capital firm based in London, specializing in pre-seed and seed investments in European Deep Tech startups, particularly in Computing, Defence, and Energy sectors.[1][2][3][4] Its mission is to build a new financial institution at the intersection of venture capital, science, and community, providing super-early capital to exceptional technical founders while leveraging a network of 15,000 founders and engineers, live pitching events (with winners now valued over £7 billion), and 24/7 support.[1][2] The investment philosophy emphasizes backing "sub-0.1% exceptional" contrarian scientists and engineers building infrastructural, defensible technologies with global impact and 1B+ revenue potential, using in-house expertise to spot disruptive trends.[1][4][6]

The firm has significantly impacted Europe's startup ecosystem by democratizing access to deep tech funding through community-sourced deal flow, pan-European reach, and operational proximity to founders, fostering a pipeline of high-conviction bets in critical infrastructure areas.[1][2][4]

Origin Story

Silicon Roundabout Ventures traces its roots to the Silicon Roundabout community, which began with informal meetups of engineers, scientists, builders, and founders near London's Old Street Roundabout.[4] The community evolved through key milestones: its first pitching event, a shift to deep tech focus (advanced software, hardware, and science), Francesco Perticarari's initial angel investment in a community startup, a hybrid pivot during Covid that opened doors across Europe, and Perticarari leaving his engineering career to launch the fund as the "business soul" of the community.[4]

Founded in 2019 (with the formal fund launching in 2023 as a solo GP vehicle), it was established by Francesco Perticarari (General Partner), a public speaker and lecturer on deep tech and VC, who closed a £5m fund backed by Molten Ventures, Multiple Capital, and exited founders from Nasdaq-listed and unicorn companies.[4][5] Key partners include Venture Partners Olivia Nicoletti and Ralph King.[5] The firm's evolution reflects a shift from local London gatherings to a truly pan-European, community-powered VC model exclusively for deep tech pre-seed and seed stages.[1][4]

Core Differentiators

• Unique Investment Model: Community-driven with live pitching competitions sourcing deals from 15,000+ founders/engineers; writes first cheques in pre-seed/seed (sometimes leading), acting as a "search function" for extreme talent via in-house science/engineering expertise.[1][2][4][6]
• Network Strength: Pan-European reach amplified by hybrid events post-Covid; backers include top VCs like Molten Ventures and unicorn operators, providing founders instant access to a vast, technical community.[1][4]
• Track Record: Winners from pitching events valued over £7bn collectively; focuses on "deeply technical," infrastructural, defensible tech (strong IP moats) in Computing, Defence, Energy with global scale.[1][2][6]
• Operating Support: "One WhatsApp away" 24/7 availability; hands-off on building but hyper-responsive, tailored for obsessively technical founders solving large-scale problems.[1][4]

Role in the Broader Tech Landscape

Silicon Roundabout Ventures rides the surging demand for Deep Tech infrastructure amid geopolitical tensions boosting Defence tech, energy transitions addressing climate challenges, and computing revolutions (e.g., AI hardware, next-gen semiconductors).[1][6] Timing is ideal: Europe's deepening tech sovereignty push post-Covid, coupled with underfunded pre-seed deep tech gaps, positions the firm to capture "picks and shovels" innovations with 10+ year horizons and 1B+ revenue upside.[1][4]

Market forces like U.S.-China tech decoupling, EU green deals, and NATO spending hikes favor its focus, while community model counters traditional VC's insider biases.[2][3] It influences the ecosystem by nurturing pan-European talent pipelines, proving community-sourced VC can scale high-conviction bets, and bridging London's "Silicon Roundabout" heritage to continental hubs.[4]

Quick Take & Future Outlook

With a compact £5m fund fully deployed into high-conviction deep tech, Silicon Roundabout Ventures is poised for Fund II expansion, potentially scaling community events and LP base amid Europe's deepening deep tech renaissance.[4] Trends like sovereign AI stacks, quantum-secure defence systems, and fusion energy breakthroughs will shape its trajectory, amplifying its role as Europe's go-to pre-seed scout for infrastructural moonshots.[1][6]

As geopolitical and climate pressures intensify, its influence could evolve from niche community fund to blueprint for decentralized, founder-first VC—ultimately powering the next wave of £7bn+ exits from today's pitches.[1][2][4] This community-driven engine, born from London meetups, exemplifies how grassroots networks fuel Europe's deep tech ascent.
