Seraf lets you mark the "Stage", or status, of each company in your portfolio for better tracking. From the Company page in Portfolio Management, you can mark each company at its appropriate deal flow stage or based on how it is performing in your portfolio. You and your investors, when applicable, can tell which company is New, in Due Diligence, Succeeding, or among the Walking Dead. There are numerous options available, including "New Category", where you can enter your own custom description. You can select the stage when you add a new company or when you edit an existing company by choosing a category from the drop-down menu.
If you'd like manage your deal flow with additional tools, analysis and reporting, please check out Seraf's Deal Flow Management for Enterprise accounts.
