Stone Soup Consulting

What Stone Soup Consulting does

Stone Soup Consulting is a privately held international social impact consultancy founded in 2008 in Portugal, with offices in Lisbon and Madrid and operations spanning Europe, Latin America, North Africa, and Southeast Asia. The firm serves civil society organisations — including NGOs, non-profits, foundations, social enterprises, and international organisations — through 15+ service modules covering organisational development, sustainability strategy, social impact measurement and evaluation, strategic planning, fundraising and financial sustainability, communication strategy, venture philanthropy and impact investment, strategic alliances, social business models, HR management, selection processes, scaling-up, training, and research. Delivery is remote-first via a distributed community of 29+ consultants across Spain, France, Portugal, Tunisia, and Mexico, supplemented by the Stone Soup Academy training programme for cohort-based capacity building.

The underlying technology is intentionally minimal: internet-based platforms (Microsoft Teams) and standard Office tools, with no proprietary software platform or AI/ML capabilities disclosed. Core intellectual property sits in methodology and brand — a certified B Corporation status since 2016, formal Code of Ethics and DEI Policy, membership in the Portuguese Diversity Charter, and a transparency practice codified through triennial Honesty Reports (2019-20, 2021-22, 2023-24) with third-party impact verification.

The business model is professional services: custom-scope consulting engagements delivered remotely with selective field presence, alongside paid training programmes through Stone Soup Academy. Pricing is not publicly disclosed, and engagement structures vary by client size and duration. Customer reach is global with 300+ organisations supported across 17 years, and self-reported impact metrics include 70-85% of clients attributing increased impact and 90% willingness to refer. The firm operates without external institutional funding, is controlled by its founder/partners, and reinvests profits into mission-aligned growth per its B Corp commitments.

Direct peers

• The Bridgespan Group: Global nonprofit and philanthropy consulting firm providing strategy, organizational design, and capacity-building services to NGOs and foundations. Closely mirrors Stone Soup's core service mix (org development, strategy, fundraising) and target segments (civil-society organizations and funders).
• La Piana Consulting: Nonprofit-only consultancy supporting NGOs with strategic planning, governance, and organizational change. Mirrors Stone Soup's civil-society focus and the operating model of a values-driven, boutique consultancy with a small partner-led team.
• NetHope: Global consortium of international NGOs and technology partners that delivers capacity-building, digital, and programmatic support to civil-society organizations. Comparable to Stone Soup in serving global NGOs with organizational and impact support, though with a stronger technology-services focus.
• Arabella Advisors: Philanthropy and impact advisory firm working with donors, foundations, and nonprofits on strategy, giving, and impact investing. Highly comparable to Stone Soup's venture philanthropy/impact investment and fundraising service modules.
• TCC Group: US-based consulting firm focused exclusively on nonprofit and philanthropic clients, offering strategy, evaluation, and organizational development. Direct overlap with Stone Soup's mission, clientele (foundations, NGOs), and service portfolio (M&E, org development, capacity building).
• Keystone Accountability: International consultancy helping NGOs and funders improve accountability, feedback, and impact measurement. Closely aligned with Stone Soup's social impact measurement and evaluation service modules, and serves a similar cross-border civil-society client base.
• FSG (now part of The Bridgespan Group): FSG was a mission-driven consulting firm advising foundations, NGOs, and corporations on strategy and impact measurement — a direct comparison to Stone Soup's organizational development and social impact measurement work. Its merger with Bridgespan Group consolidates this peer set into one major global player serving the same civil-society client base.

Others

• Social Value International: Global network focused on social value and SROI principles, with whom Stone Soup has engaged. Functions more as a standards body and community than a direct competitor, but its member consultancies address the same impact-measurement buyer need that Stone Soup serves.

Regional players

• Inspiring Impact: UK initiative promoting impact measurement and good practice across the social sector. Comparable to Stone Soup's impact-measurement and training work via the Stone Soup Academy, but primarily focused on UK-based civil-society organizations.
• Phineo gAG: German social-analytics and impact-measurement organization advising civil society on effectiveness and impact. Comparable to Stone Soup's social impact measurement practice, but primarily serves German-speaking Europe rather than Stone Soup's Iberian/global footprint.
