What Yellow Walnut does
Yellow Walnut B.V. is a privately held Dutch company headquartered in Amsterdam (Zekeringstraat 36) that operates an integrated multi-venture platform serving Dutch entrepreneurs, particularly ZZP'ers (solo freelancers) and MKB (small/medium businesses). Founded in 2012 by Adriaan van Loon and Annette Wassenaar, the company targets the 1.1 million full-time solo entrepreneurs in the Netherlands and reports 24,353 entrepreneurs in its ecosystem. The platform comprises three wholly-owned ventures: Yezzer (online insurance distribution for ZZP and MKB), Boostz (online training and webinars led by named Dutch entrepreneurs), and Yellow Walnut Legal (subscription-based first-line legal advice from €39/month using a shared in-house legal team model).
The underlying technology is a web-based platform built on Zend Framework with SendGrid SMTP for email, integrating LinkedIn for single sign-on and iDEAL for payment processing. The Yellow Walnut Legal service operates on a shared legal team model where subscribers pool access to in-house lawyers between 08:00–20:00 on business days, reducing per-user cost versus traditional Dutch law firm hourly rates. Yezzer customers receive a free Boostz Plus subscription, creating cross-venture cross-selling between insurance and training products.
The business model combines three revenue streams: recurring subscriptions for Yellow Walnut Legal (€39/month with 12-month contracts and automatic monthly renewal), subscription and per-course pricing for Boostz training (e.g., €299/year for the social media course), and affiliate/referral revenue from insurance distribution via Yezzer partnerships with insurers such as Aegon and ASR. Distribution is online and self-serve for Yezzer and Boostz, with direct telephone support for Legal. The company remains bootstrapped with no disclosed external funding, maintains brand-level partner relationships with major Dutch institutions (ABN AMRO, Rabobank, KPN, Philips, PostNL, TNO, Arcadis), and has secured earned media coverage in Telegraaf, BNR, Sprout, Emerce, NU.nl, and Financieel Dagblad.
