What Einstrukcije does

Einstrukcije is a Croatian online tutoring marketplace operated by Kontrabit Services j.d.o.o., founded in Zagreb in 2020 by Roman Krvavica and Robert Ljubanović. The platform connects parents and students (primary, secondary, and university level) with certified instructors for individualized one-on-one video tutoring sessions in subjects spanning mathematics, physics, chemistry, biology, IT, languages (Croatian, English, German, French, Italian, Latin), electrical engineering, mechanics, statistics, and accounting. It also offers specialized preparation for the Croatian state matura (eMatura), including free downloadable study scripts (Skripte) for mathematics, Croatian, and English at multiple difficulty levels.

The core technology is a self-serve web platform with a virtual classroom featuring video calling, an interactive whiteboard, screen sharing, document exchange, and session recording. Instructor supply is curated through a six-category certification process (professional knowledge, social skills, IT literacy, communication skills, methodology, and teaching ability) with only approximately 5% of applicants accepted. Payment is processed upfront via WSPay with PCI DSS and SSL/TLS 1.2 compliance, and the platform operates under GDPR for EU personal data handling.

The business operates on a per-session, direct-to-consumer marketplace model, with prices set by individual instructors and not publicly disclosed on the website. Customers select a subject, choose an instructor, reserve a time slot, and pay online via credit/debit card or internet banking. The company is bootstrapped with no external institutional funding disclosed, with a registered share capital of EUR 1.00. Scale commentary cites roughly 100 certified instructors, 5,000 users, and 40,000 completed sessions cumulatively since launch, with approximately 40 full-time and 30 part-time instructors actively engaged.

Broad incumbents

• Tutor.com: Established US online tutoring service offering 1-on-1 on-demand sessions with vetted tutors. Comparable instructor-vetting and per-session delivery model, though English-language and primarily K-12/college oriented.
• Brainly: Large peer-to-peer homework help and learning platform with strong presence in Central/Eastern Europe. Competes with eInstrukcije on the homework-help and exam-prep use cases, though as a community Q&A product rather than 1-on-1 paid tutoring.
• GoStudent: Large European K-12 online tutoring platform with vetted instructors, recurring subscription model, and content-plus-tutor integration. Comparable to eInstrukcije's integrated tutoring + content architecture but at much greater scale across multiple EU markets.

Direct peers

• italki: Global online marketplace primarily for language tutors, with community-validated teacher profiles and 1-on-1 video lessons. Comparable to the language-tutoring slice of eInstrukcije's offering and its marketplace dynamics.
• Superprof: International marketplace for private tutors across academic subjects and languages, with strong European footprint including the Balkans. Competes head-to-head on the same student-instructor matching value proposition as eInstrukcije.
• Preply: Global online tutor marketplace connecting students with vetted instructors across many languages and academic subjects. Closest direct competitor to eInstrukcije's marketplace model, though operating at global rather than national scale.
• Wyzant: US-based online tutoring marketplace where students browse and book vetted instructors across subjects. Closely mirrors eInstrukcije's per-session, instructor-choice, video-call delivery model.

Others

• Khan Academy: Free, high-quality structured video and exercise content across K-12 STEM and exam prep subjects. Not a paid tutor marketplace, but the dominant free alternative that constrains eInstrukcije's pricing on subjects like mathematics and physics.

Regional players

• Classgap: Spanish-origin online tutor marketplace with growing presence in Southern European markets including the Balkans. Comparable marketplace mechanics and per-session pricing structure to eInstrukcije.
• Studocu: European student-to-student study-material and notes platform with strong university and secondary-school traction. Comparable as a free study-content acquisition channel for exam preparation, similar to eInstrukcije's eMatura scripts.
