What Renga does
Renga Software LLC is a Russian joint venture between ASCON and 1C, founded in 2016 to develop a domestically produced Building Information Modeling (BIM) system for architectural, structural, and MEP engineering design. The company offers two commercial editions — Renga Standard (Registry No. 7810) for small and medium businesses and individual use, and Renga Professional (Registry No. 19343) for complex collaborative projects — together with a free educational license and a home-use non-commercial tier. The platform is built on the licensed Russian C3D geometric kernel in C++20/MSVC with Qt, supports IFC4/OpenBIM interoperability, and exposes a COM-based API plus the STDL domain-specific language (Lua/JSON) for custom parametric equipment categories; Renga Collaboration Server enables multi-user real-time design. New functionality is released approximately every six weeks.
The business model combines perpetual licenses (190,000–235,000 RUB Professional) with annual subscriptions (95,000–117,000 RUB Pro / 60,000–88,000 RUB Standard) and maintenance/update subscriptions for perpetual holders; pricing is ruble-denominated, registered for VAT exemption under Article 149(2)(26) of the Russian Tax Code, and accompanied by trade-in and Switch-from-Foreign-CAD programs that target users migrating off Western platforms. Distribution is channel-first through ASCON's 35+ Russian-city reseller network and 1C partners, supplemented by direct e-commerce for SMB/home users; an 11+ partner plugin ecosystem (ModPlus, САПР-Альфа, АВС-4, BIM WIZARD, УМНАЯ ВОДА, Aristos 3D, Luch Render, etc.) and deep native integration with the 1C enterprise stack (1С:ERP, 1С:Smeta, 1С:PM, 1С:Аренда) extend the core product into adjacent workflows. Renga serves enterprise and mid-market customers including Setl Group, ATTA Group, Самолёт, Кайрос Инжиниринг, ЦПТИ Росатома, ГКУ УКС Мордовии, and educational institutions СПбГАСУ and МГСУ, operating in Russia, Belarus, Kazakhstan, and Uzbekistan.

Renga partnerships and signals
Strategic signalPartnerships
Five partnerships are on record, tiered core and minor.
- C3D Labs (C3D геометрическое ядро)coreRenga uses the licensed Russian C3D geometric kernel as its 3D geometry engine. Renga holds a C3D license certificate and is certified as a licensed user of C3D Labs' geometric kernel. This is a foundational technology dependency — the C3D kernel handles all 3D geometry operations in Renga.
- СПбГАСУ (Санкт-Петербургский государственный архитектурно-строительный университет)minorСПбГАСУ hosts the annual Summer BIM School for educators on its campus. The university provides the venue and participates in curriculum development. Renga and СПбГАСУ jointly develop educational methodology and teaching materials for BIM education in Russian universities.
- ФАУ ФЦС (Федеральный центр нормирования и стандартизации)minorRenga Software collaborates with ФАУ ФЦС and state expert bodies to test new national BIM standards on pilot projects. Renga is a member of ТК465 ПК5 (BIM standardization technical committee) and participates in expert council meetings at the Russian Ministry of Construction.
- АСКОНcoreRenga Software is a joint venture (JV) of АСКОН and 1С, created in 2016. АСКОН provides the common data environment (Pilot-BIM), CAD technology, and access to its regional partner network across 35+ Russian cities. АСКОН and Renga jointly develop BIM solutions, with Renga Professional being a core component of АСКОН's BIM ecosystem. Chairman of the Board of Directors is Alexander Golikov.
- 1Сcore1С is the second parent company of Renga Software JV. It provides deep integration with the 1С enterprise software ecosystem (1С:ERP, 1С:Smeta 3, 1С:PM, 1С:Rieltor, 1С:Arenda), access to the 1С partner network for distribution, and collaborative marketing via 1С events and channels. The JV structure gives both parents access to each other's installed base and implementation resources.

Renga competitors and assessment
Company assessmentOthers
- C3D Labs: C3D Labs licenses the C3D geometric kernel that Renga uses as its 3D engine. Enabling technology partner, not a direct competitor, but a structurally important peer whose kernel roadmap shapes Renga's capabilities.
- ASCON (parent / Pilot-BIM): ASCON is both a JV parent of Renga and the provider of the Pilot-BIM common data environment that Renga Professional integrates with. Closely aligned ecosystem peer; ASCON's broader CAD/PLM suite shares the same customer base and distribution.
- 1C (parent): 1C is the other JV parent and the dominant Russian enterprise software provider whose ERP, PM, and Smeta products integrate natively with Renga. Strategic ecosystem peer and channel partner rather than direct competitor, but defines Renga's go-to-market scale.
Direct peers
- Graphisoft (Archicad): Archicad is an architectural BIM platform widely used in CIS design bureaus. Direct comparable as a vendor-built BIM suite targeting architects with similar collaboration and documentation automation, now owned by Nemetschek.
- Trimble Tekla Structures: Tekla is a structural BIM application used for steel and concrete detailing, directly comparable to Renga's Structure module for reinforcement and precast design, and competing in the same industrial and infrastructure customer base.
- Nemetschek Allplan: Allplan is a multidisciplinary BIM platform (architecture, structure, MEP) with strong European and CIS presence. Direct comparable across Renga's full architectural/structural/MEP scope, targeting similar mid-market and enterprise design organizations.
Broad incumbents
- Autodesk (Revit / AutoCAD): Global leader in BIM (Revit) and CAD (AutoCAD), historically dominant in Russian design institutes. Directly comparable as the incumbent Renga is positioned against in the Russian BIM market, with broader portfolio across AEC, manufacturing, and media.
- Bentley Systems (OpenBuildings / AECOsim): Bentley provides BIM and digital twin solutions for buildings and infrastructure, including OpenBuildings. Broad incumbent with overlapping AEC capabilities, used by large infrastructure and industrial clients that also overlap with Renga's enterprise base.
Emerging players
- Bricsys (BricsCAD BIM): BricsCAD BIM is a DWG-native BIM platform with growing CIS presence. Emerging peer with overlapping architectural and MEP functionality, competing for the same cost-conscious design bureaus that Renga targets.
Regional players
- nanoCAD (Nanosoft): Russian-developed CAD platform with BIM-adjacent functionality, widely deployed across Russian design organizations. Regional peer in the same domestic-AEC market, often used alongside Renga in mixed-tool design workflows.
