Tetrika

What Tetrika does

Tetra is a Russia-based online tutoring school operated by Moscow-incorporated OOO «PREPREP.RU» (founded 2018), serving primarily K-12 students (ages 4–18), adult learners, and corporate clients nationwide via a proprietary browser-based platform that requires no software download. The platform delivers one-on-one and small-group lessons (from 2 students) through an integrated stack of live video chat, a virtual interactive whiteboard, a personal dashboard with chat, self-study recorded video courses, and an automated exercise-grading system. Core academic offerings span grades 1–11 across mathematics, Russian, English, physics, chemistry, biology, history, geography, social studies, literature, and computer science, together with structured preparation for the Unified State Exam (ЕГЭ), Basic State Exam (ОГЭ), All-Russian Verification Works (ВПР), Additional Internal Examinations (ДВИ), and academic Olympiads. Specialized extensions include speech therapy (логопед), an 'AI for Kids' educational course, soft skills/leadership/finance for teens, an MBA-style teen business school (96 group sessions), and an IT/programming masterclass.

Tetra maintains a curated network of 3,700+ tutors (described as ЕГЭ experts, candidates of sciences, and language specialists with international certifications) serving roughly 41,000 active students, with cumulative lessons crossing 1.8 million. The business model is direct-to-consumer with a free introductory lesson converting through a 15-minute phone callback into lesson-package purchases (8, 16, 24, or 32 lessons), supported by installment financing with Tinkoff Bank and Sberbank (Tetra absorbs the interest to keep customer cost flat) and a 1:1 referral program granting 3 bonus lessons per side. A secondary B2B vertical sells Corporate English to Russian companies with 50% or 100% company-funded tariff structures. Marketing is multi-channel: a free content library and parent webinars operate as top-of-funnel lead magnets; promo codes (e.g., 'Hello8') and bonus lessons (3 free with 32+ package) drive mid-funnel conversion; and active presence on VKontakte, Telegram, and Pinterest sustains community and organic reach. Total disclosed funding across 2019–2020 is approximately $1.81M, with VK (ex. Mail.Ru Group) as the named strategic investor.

The company is privately held by its three co-founders (Anton Ivanov, Maxim Gadzhiev, and Nikolai Spiridonov), with no disclosed venture or institutional ownership beyond the 2019–2020 VK-led rounds, and operates from a single Moscow headquarters (Nizhnyaya Syromyatnicheskaya Street). Geographic scope is exclusively Russia, with no international footprint disclosed and no public API or SDK offering.

Direct peers

• Skyeng: Russia's largest online English-language school, with similar one-on-one tutor model, dedicated platform and self-study content. Directly comparable in the Russian adult/corporate English segment where Tetrika also competes.
• Foxford: Online school for school subjects and exam preparation (EGE/OGE/Olympiads) in Russia, also owned by the VK/Mail.ru Group. Most direct competitor on K-12 academic tutoring and Russian state-exam prep.
• Uchi.ru: Russia's leading K-12 digital education platform with adaptive assignments and teacher dashboards; owned by VK. Comparable as a Russian K-12 online learning ecosystem serving students, teachers and parents, though it focuses more on in-school digital curriculum than tutoring.
• EnglishDom: Russian online English-language school offering individual and corporate English training. Directly overlaps Tetrika's adult English and corporate English B2B offering.
• Maximum Test (Maximum): Russian online exam-prep platform with prep courses for EGE, OGE and Olympiads. Closest direct competitor on the high-stakes Russian standardized exam segment.
• Repetitor.ru: Russian online marketplace for individual tutors across school subjects and exam prep. Comparable in subject breadth and tutor-mediated one-on-one model, though transactional rather than platform-curriculum-led.

Broad incumbents

• Preply: Global online tutoring marketplace spanning languages, academics and exam prep. Comparable business model (one-on-one online tutors, package pricing, content funnel) but operating at international scale beyond Tetrika's Russia-only footprint.
• Varsity Tutors: US-based online tutoring and test-prep platform offering one-on-one instruction across subjects and standardized exams (SAT/ACT/GRE/GMAT). Closely comparable category (online tutoring + test prep) though operating in a different geography and exam system.
• Tutor.com: Long-standing US online one-on-one tutoring platform serving K-12 and higher education across subjects. Comparable delivery model (online one-on-one with tutor) and target outcomes (homework help, exam success).

Emerging players

• Cambly: Online English conversation platform connecting students with native-speaker tutors. Partial overlap with Tetrika's adult English and corporate English segments, though concentrated in conversational practice rather than exam prep.
