Despite investing some $80 billion a year and helping coach the world's fastest-growing companies, the venture capital business is oddly unsophisticated. Most firms lack basic corporate functions, such as human-resources departments or employee codes of conduct. The consequences of this weren't readily apparent until last year, when more than a dozen women came forward with allegations of harassment against VCs.

The industry is now getting some long-overdue help, and it's coming from a Washington lobbying group. The National Venture Capital Association, the trade group representing American VCs, published a trove of HR documents on Thursday encouraging firms to adopt new policies to define unacceptable workplace behavior. The paperwork describes what constitutes sexual harassment and discrimination, and outlines a procedure for handling complaints. HR best practices, diversity and inclusion policies, paid parental and family leave, and a code of conduct are also covered in the documents.

The initiative is the culmination of eight months of work by the industry group, member firms and experts in legal, HR and employment issues. VC firms aren't required to adopt the policies. The effort stopped short of creating a central system for victims to report inappropriate behavior, for which some have advocated. "With the release of these tools and resources, we've taken a positive step forward to address sexual harassment and create a more welcoming industry, but more work remains to strengthen venture capital for the better," Bobby Franklin, the NVCA president and chief executive officer, said in an emailed statement.
