Problem setting. The concept of post -industrial society implies that the economy of modern states should prevail in the innovation sector with high -yielding industry, knowledge industry and high proportion in GDP of high -tech and innovative services. In this approach, information is considered by a separate full -fledged resource, which not only does not infer the traditional material resources, but may also be more important. The development of the economy in the realities of post -industrial society requires the creation of favorable conditions for the activity of competitive innovative enterprises, many of which begin as startups and SMEs. At the same time, such enterprises require significant individual information support and support. In order to understand what support can be calculated by representatives of the domestic innovation sphere, it is advisable to inspect and compare the services that contribute to their information support. One of the varieties of such services is information and communication platforms. Analysis of resent researches and publications. The roles of startups, SMEs and innovative infrastructure in modern society are devoted to many works of employees of the Research Institute of Providing Legal Framework for the Innovative Development, in S. V. Hlibko, D. S. Korytin, I. V. Podrez-Riapolova, M. H. Khaustova et al. Among the domestic scientists involved in the issues of information and communication technologies and systems, it is possible to distinguish K. O. Bezuhla, P. M. Lissov, P. P. Maslianko.

Special emphasis is placed on information and communication platforms, in particular on the development of the Scientific and Research Institute of Providing Legal Framework for the Innovative Development – Smart Law Innovation platform (SLI). The definition and classification of infocommunication systems, which allows you to outline the essence of Smart Law Innovation, is given. The article pays attention to the importance of information for building a modern competitive economy in the postindustrial world. While innovative activity is a prerequisite for the described development, information support is an important condition for the activity of innovative entities. The article emphasizes the importance of information support (information and counseling) of startups and SMEs, which bring a significant share to the innovative development of successful countries, but require special support for launching, developing and avoiding risk. Enterprise Europe Network and its regional centers (on the example of the Polish Center Podlaska Fundacja Rozwoju Regionalnego) are explored to analyze the EU’s positive experience in the field of business. Services provided by the domestic network of business support centers, formed for the financing of the European Union under the EU4Business initiative during 2016-2020, are paying attention to a positive trend to the formation of online online communities providing online services. Services offered by platforms are performed. Attention is paid to powerful positive experiences and powerful sides that can offer outlined services. The final part of the article is devoted to the inspection of the information and communication platform of the Smart Law Innovation and its comparison with the existing concrete proposals outlined above. Conclusions and prospects for the development. The development of innovative enterprises is a prerequisite for building a competitive economy in the post-industrial world. At the same time, information support is an important condition for launching, developing and avoiding risks. The importance of timely information and counseling is especially noticeable for startups and SMEs, which bring a significant share in the innovative development of successful countries. Proper use of electronic technologies and the development of infrastructure capable of assisting innovative entities can significantly contribute to Ukraine’s economic reconstruction. Further analysis of the EU’s positive experience, including Enterprise Europe Network, can be used to increase favorable business conditions in Ukraine. In addition to state support, the article draws attention to private projects that provide information support and counseling, including online services, formed by lawyers and individual consulting projects. One of the projects that provides information support for innovative subjects, researchers and ordinary citizens is the Smart Law Innovation Information and Communication Platform, developed by the Research Institute of Legal Support of Innovative Development of the National Academy of Sciences of Ukraine. Although the platform is still under development, the analysis of competitive proposals allows you to see a number of advantages over this development.
