Mustard Seed MAZE

The investment team is led by partners Alex Pitt, António Miguel, and Henry Wigan, supported by Investment Principal Sofia Queiroz. Venture partners including Tessa Clarke and Jessica Jackley provide additional sourcing and diligence support. The firm maintains a lean structure with ten team members listed on its website across investment, operations, and platform functions.

Mustard Seed MAZE has published internal research on using a data-driven approach to improve sourcing of impact ideas, indicating it uses proprietary screening tools beyond traditional network-driven origination. The venture partner network — including operators such as Tessa Clarke of Olio and Jessica Jackley of Kiva — provides additional founder access across European sustainability and inclusion ecosystems.

Yes, impact is central to the mandate, not a separate sleeve. Every portfolio company is assessed against the Impact Management Project guidelines and mapped to specific UN Sustainable Development Goal targets. Holdings range from circular-fashion marketplaces such as Sojo and Thrift+ to clinical-trials AI platform Biorce and residential energy provider Samara.

The firm invests across early stage, including seed and start-up, and can follow on into growth rounds. Portfolio companies are based across Europe, with concentrations in Lisbon, London, Berlin, Paris, and Barcelona. The stage mandate suits ventures with initial commercial traction and a path to global markets.

No. Mustard Seed MAZE has not publicly disclosed its AUM or aggregate deployment. The firm's website references institutional LP backing, but no regulatory filings, press reports, or voluntary disclosures provide a specific number.

The firm applies the Impact Management Project framework and maps each portfolio company to relevant UN Sustainable Development Goals. Public materials do not detail the frequency of impact reporting to LPs, but the firm's content — including analyses of founder reporting as a predictor of venture performance — suggests an in-house measurement capability that goes beyond standard impact-accounting templates.

The firm does not publish a negative screening list. However, the portfolio's SDG alignment and impact thesis naturally exclude industries such as fossil-fuel extraction, weapons manufacturing, and sectors with no plausible path to positive social or environmental outcomes. Target areas concentrate on climate, health, education, economic inclusion, and circular-economy models.
