ZIZ SOA zorg

What ZIZ SOA zorg does

Stichting ZIZ, operating as ZIZ SOA zorg, is a Dutch non-profit foundation established in 2022 by healthcare providers to deliver faster, cheaper, and more accessible STI and PrEP care. It runs walk-in clinics in the four largest Dutch cities — Den Haag (headquarters), Utrecht, Amsterdam, and Rotterdam — supplemented by a national home-testing kit channel. Each location houses its own ISO 15189-compliant laboratory, enabling on-site rapid PCR results within 30–90 minutes, a structural departure from the multi-day turnaround of traditional GP/lab pathways. Treatment for diagnosed STIs is bundled at no additional cost.

The core product is a CE-marked eHealth consultation (medical device) that triages patients via an online questionnaire and uses a machine learning model to estimate the probability of a positive test result. Based on this triage, patients receive a personalized test recommendation, walk into a clinic without appointment, and complete STI testing, counseling, treatment, and (if needed) specialist referral in a single integrated visit. Tests cover Chlamydia, Gonorroe, Syfilis, HIV, Hepatitis B/C, Trichomonas, Mycoplasma (with resistance testing), and LGV, using a proprietary sample pooling methodology across multiple body sites.

ZIZ monetizes through a unique "zorgprestatie" arrangement in which all Dutch health insurers contribute €32 per visit without affecting the patient's annual deductible, reducing patient out-of-pocket cost by roughly 60% versus the GP pathway. Additional revenue comes from PrEP medication sales (€22–€85 per package, delivered by Nationale Apotheek) and self-pay pricing for uninsured patients. The foundation explicitly operates without shareholders or private equity, reinvesting surpluses into care delivery. Its go-to-market relies primarily on earned media (NOS, RTL, AD, FunX radio) and targeted community outreach to MSM and under-25 demographics.

Revenue model

1. Insured Healthcare (Zorgprestatie): Patients pay a portion upfront; health insurers pay €32 per visit without affecting the patient's deductible. This unique arrangement with all health insurers makes ZIZ approximately 60% cheaper than GP or commercial providers. Treatment is always included in the price.
2. PrEP Medication Sales: Sale of PrEP (HIV pre-exposure prophylaxis) medication. Patients purchase tablets directly (30, 90, or 180 tablet packages). Includes mandatory periodic testing.
3. Self-pay Testing (No Dutch Insurance): Patients without Dutch health insurance can self-pay the full €31.98 contribution that would normally come from the insurer.

Expansion highlights6 records

Broad incumbents

• STAR-SHL: Large Dutch diagnostic laboratory used by GPs for STI/medical testing. Cited by ZIZ as one of the comparison labs whose turnaround is slower (days/weeks) and whose combined GP-plus-lab-and-pharmacy pathway is more expensive than ZIZ's integrated offering.
• LetsGetChecked: Global direct-to-consumer home health testing company offering STI panels among broader diagnostics. Operates in adjacent European markets and represents a comparable at-home testing experience to ZIZ's home kit offering.
• Eurofins Clinical Diagnostics: Major commercial medical diagnostics laboratory used by Dutch GPs and hospitals. A reference comparator for ZIZ's pricing model and a potential threat if it moves into faster patient-direct turnaround offerings.
• GGD (Gemeentelijke Gezondheidsdienst) STI Clinics: Municipal public health services in the Netherlands that provide free STI/sexual health testing and treatment. ZIZ explicitly positions itself as complementing GGD by reducing pressure on its clinics while offering faster, paid alternatives with broader hours and locations.

Direct peers

• Homed-IQ: Dutch provider of at-home STI and health test kits with mail-in samples and online results. Overlaps with ZIZ's home testing kit channel and targets the same Dutch market for discreet sexual health testing.
• PrEPnu: Dutch online PrEP service providing HIV pre-exposure prophylaxis with associated testing. Closely comparable to ZIZ's PrEP care package including medication delivery and mandatory STI/kidney testing.
• OneDayClinic: Dutch chain of walk-in STI testing clinics offering rapid results and online booking. Competes directly with ZIZ on the same Dutch consumer-facing STI testing proposition across multiple cities.
• MyLab (Nordic/Dutch home testing): Home STI and health testing brand operating in the Netherlands and Nordics with mail-in sample collection. Directly comparable to ZIZ's home testing kit offering for chlamydia, gonorrhea, HIV and other STIs.

Others

• Soa Aids Nederland: Dutch national STI/HIV awareness and advocacy organization. ZIZ cooperates with the broader sexual-health ecosystem in the Netherlands and Soa Aids Nederland helps shape public awareness and screening policy that affects ZIZ's demand.

Regional players

• Centrum Seksuele Gezondheid (CSG): Dutch sexual health centers with which ZIZ has a referral and coordination partnership. Comparable in offering sexual health/STI consultations and treatment pathways that overlap with ZIZ's core services.
