LEDAS Ltd. is an independent software development company founded in 1999 in Novosibirsk, Russia. LEDAS provides computational components and services to its customers — PLM (CAD/CAM/CAE/PDM) and ERP software development companies and manufacturing enterprises, using its core competence in mathematics, computer science and computer-aided design, solid experience in software development & 3D modeling, proprietary technologies, and advantages of its location. LEDAS actively promotes PLM (product lifecycle management) and ERP (enterprise resource planning) business strategies by organizing multi-vendor conferences, publishing books, and supporting dedicated web-resources.

We at LEDAS perceive our mission as the automation of key industrial processes — design, simulation and planning. These are the areas where system users require a set of intelligent functions in order to accelerate product development and planning of related processes and resources. We help our customers develop intelligent applications, promote, and deploy them.

During our long history (including its academic “pre-history”) we have developed several state-of-the-art computational technologies in the following fields:

  • Geometric constraint solving
  • Collision detection & motion simulation
  • Interval constraints
  • Scheduling

Based on these technologies, we have developed several software products — computational components — and proposed them for licensing.


Based on our own state-of-the-art technologies, LEDAS developed several computational software components (engines and solvers) that are licensed by software development companies for integration into the end-user software:


For its customers, LEDAS provides a set of services related to software development and other outsourcing activities:

  • Consulting on our technologies
  • Integration of our components into the customer’s software
  • Computational software development
  • Application customization and add-on development
  • Training of customer’s personnel

Standard hourly rate for outsourcing software development at LEDAS varies from $30 to $45 depending on professional skills needed to perform a particular task, and the volume and regularity of tasks from a particular customer.

The attractiveness of our skills/rate ratio has been proven by the long-term strategic partnership between LEDAS and the world leading software development companies.


Quite a few software development companies have licensed our software components:

  • Proficiency (Israel)
  • ADEM Technologies (Russia)
  • AWV (Switzerland)
  • Tecnos (Italy)
  • Evo.Solutions (Japan)
  • JRI Solutions (Japan)

Free academic licensees were granted to:

  • Novosibirsk State University
  • Novosibirsk State Technical University
  • Purdue University (USA)
  • Northwestern Polytechnic University (China)

Since 1999, we have developed the core computational components for CATIA V5 and other products of Dassault Systemes (France), and we cooperate with DS in localizing their software for the Russian market.

LEDAS headquarters is in Akademgorodok, which is a world-famous educational and scientific center in Novosibirsk, Western Siberia, the third largest Russian city after Moscow and St-Petersburg.

Created 50 years ago in the ecological heaven of the pine forest 20 km south to Novosibirsk on the bank of the Ob river, Akademgorodok became a home for 35 research institutes of the Russian Academy of Sciences (with 5,000 scientists), 50 IT companies (with 1,500 programmers), and 30 other high-tech companies (with 1,000 engineers). Many world-leading technological companies have R&D offices in Akademgorodok, including Intel, Schlumberger, and Samsung.

Novosibirsk State University (one of the leading Russian universities in Mathematics, Physics and Biology) with its 6,000 students is a unique source of highly qualified workforce for LEDAS.

In 2005, a TechnoPark was started in Akademgorodok, already comprising 160,000 m2 of labs & offices, to establish a stronghold of Russian innovative economics, based on the existing scientific potential in IT, bioinformatics, and electronics.


LEDAS is the main organizer and sponsor of isicad biennial PLM forums in Novosibirsk, which are always a stage for 3-days discussions between end users (representing 300 manufacturing enterprises across all Russia), software developers and resellers (representing 30 CAD, CAM, CAE, PDM and ERP companies, including Autodesk, Dassault Systemes, Oracle, PTC, SAP, and Siemens PLM Software), scientists (representing the leading Russian and European technical universities), and the key Russian mass media in the fields of CAD/CAM/CAE, PLM and ERP.

See more details on each of the conferences at the dedicated web-sites:


Performing its mission, LEDAS popularizes PLM and ERP business strategies and software tools in a series of books written by its specialists:


LEDAS sponsors and supports a bilingual PLM+ERP portal isicad.ru. The Russian part (isicad.ru/ru) presents the PLM world for the Russian community, while the English part gives information about the Russian PLM market for the international audience.

At isicad.ru you can always find:

  • Important information on CAD/CAM/CAE/PDM/ERP, including news, press-releases, announces and reports on related events
