Denver-based TrackVia, a provider of online database software, said Monday that it is now offering its service free of charge to nonprofits. According to the venture-backed firm, it will allow nonprofits to use its platform to track and communicate with donors, volunteers, and families in need. The firm said that nonprofits have been using its service to manage things like email campaigns, mail-merge documents, and printed labels. Trackvia said it requires a copy of IRS certification of non-profit status to receive the free access. TrackVia is venture backed by Flywheel Ventuers, Access Venture Partners, and others.
