What More Onion does

More Onion is a Vienna-headquartered digital mobilisation agency founded in 2008 that serves progressive non-profit organisations across Europe through two legal entities: More Onion Ltd in the United Kingdom and more onion e-campaigning GmbH in Austria, with an additional branch in Berlin. The company delivers strategic digital campaigns, fundraising programmes, supporter journey design, Facebook lead generation, donation page optimisation, and professional training to charities and NGOs focused on progressive causes including humanitarian aid, environmental protection, human rights, animal welfare, and social justice. More Onion has completed over 1,000 projects for more than 100 organisations since inception, with named clients including Shelter, Amnesty International UK, Greenpeace, CARE International, Compassion in World Farming, Four Paws, BUND/Friends of the Earth Germany, Oxfam Deutschland, Versus Arthritis, and St Mungo's.

The company's technical core is Impact Stack, a proprietary open-source mobilisation and fundraising platform that provides petition tools, secure donation processing, supporter journey automation, multi-language campaign management (covering 22+ EU languages), CRM and email marketing integrations, and an officially certified European Citizens' Initiative signature collection system. Notable deployments include Four Paws (5M+ contacts across nine countries), the End the Cage Age ECI (approximately 1.4 million signatures across 28 countries), Oxfam Germany's Lieferkettengesetz petition (26,000+ signatures), and Our Fish (40,000-supporter email list growth in six months). The platform integrates with Salesforce (via partner Clouderia), Mailchimp, and FundraisingBox.

More Onion's revenue model combines professional services (bespoke digital campaign strategy and execution, quote-based project work), public and in-house training programmes (£360/€420+VAT per seat for supporter journeys, digital copywriting, and creative facilitation), and Impact Stack platform subscriptions. Go-to-market is consultative enterprise field sales targeting European non-profits, supported by content-led inbound marketing through free reports, sector conferences (including the company's own Impact Space), and case-study-driven demand generation. The firm operates with a 1-10 person team across London, Vienna, and Berlin, is privately held with no disclosed external funding, and holds UK ICO registration (ZA208536) and GDPR-compliant EU operations.

Direct peers

• NationBuilder: Software platform for organising, fundraising, and campaigning used by non-profits and political campaigns. Overlaps with More Onion in providing integrated supporter management and digital mobilisation tools, with broader political campaign exposure.
• Action Network: US-based digital campaigning and fundraising platform serving progressive non-profits. Competes directly with More Onion's Impact Stack on petitions, donations, and supporter journeys, though focused on the US market rather than European coalitions.
• New/Mode: Advocacy and campaigning technology company serving progressive non-profits and trade unions in North America and Europe. Closely aligned with More Onion's mission-driven, mobilisation-focused positioning.
• Funraise: Modern non-profit fundraising platform offering donation forms, peer-to-peer campaigns, and CRM. Direct competitor to Impact Stack's donation and supporter journey functionality for mid-market and enterprise NGOs.
• NeonCRM: Cloud CRM built specifically for non-profits, including fundraising, membership, events, and volunteer management. Overlaps with More Onion's CRM-integrated approach to supporter engagement.
• ControlShift: Labour and progressive movement platform for petitions, events, and member engagement. Competes in the same niche as Impact Stack for progressive-cause organisations and unions across Europe and North America.
• Classy (GoFundMe Pro): Online fundraising and donor management platform purpose-built for non-profits. Competes directly on donation processing, campaign pages, and supporter engagement — overlapping significantly with Impact Stack's fundraising module.
• Bonterra (Network for Good, GiveGab, Funraise): Vertical SaaS suite for non-profit fundraising, CRM, and donor management. Competes with Impact Stack on the fundraising/CRM layer for the same NGO buyer, but with deeper US market penetration and broader feature breadth.

Emerging players

• Lightful: UK-based digital engagement and training platform for non-profits. Closely aligned with More Onion's training-led, content-driven approach to building non-profit digital capacity, with similar UK geographic focus.

Broad incumbents

• Salesforce (Nonprofit Success Pack): Global CRM giant with a dedicated non-profit programme (NPSP) and discounted pricing for NGOs. Competes with Impact Stack at the CRM and supporter data layer, and is an integration partner rather than pure competitor — but its scale and free offering threaten SaaS pricing power.
