Blackstone is weighing a potential sale of ISN Software in a deal that could value the Dallas-based compliance software firm at more than $6bn, including debt, according to Bloomberg.

The private equity giant is reportedly in discussions with investment banks as it explores both full and partial exit scenarios.
ISN, which provides contractor and supplier information management solutions through its ISNetworld platform, has seen growing relevance as companies face rising regulatory, cybersecurity, and ESG requirements. The platform is used by roughly 850 enterprises, including Exxon Mobil, Honeywell, and Cisco Systems, to ensure compliance with health, safety, and sustainability standards.

Blackstone Growth acquired a minority stake in ISN in 2020, valuing the company at $2bn. Since then, the market for compliance software has expanded significantly, fuelling interest from both industry players and private equity firms.

While discussions remain in the early stages, sources familiar with the matter say several buyers have already expressed interest. However, there is no certainty a deal will proceed.

ISN continues to be led by founder William Addy, Executive Chair Joseph Eastin, and CEO Brian Callahan.
