In the noisy world of ESG and impact investing, Sinzer.org operates in silence, yet their financial footprint speaks volumes. While most startups chase vanity metrics, this Dutch boutique has built a sustainable engine with just 8 employees.

"Traffic is zero, revenue is half a million. They aren't building for the public web; they are building for enterprise wallets."

The lack of a tech stack footprint is telling. Unlike startups that blast the web with tracking scripts, Sinzer appears to run a lean, possibly custom or low-code infrastructure. This isn't a growth-stage company burning VC on ads; it's a bootstrapped or quietly funded entity maximizing margin per client. The absence of a Trustpilot rating further confirms they don't rely on public sentiment—they rely on closed-door contracts.

• Revenue-per-employee ratio of $75k suggests high-margin consulting or enterprise software.
• Zero public traffic implies a closed-loop sales model (referrals, partnerships, direct sales).
• Staffing impact consultants indicates a service-led product strategy.
