Cerb is a fast and flexible CRM toolkit. Remember anything about anybody, reply to a flood of e-mail, quarantine spam, capture feedback organically, track time, flag opportunities, share tasks, and otherwise collaborate efficiently. Built for one-person startups through Fortune 500 giants.
The project has canonized the best practices, and learned from the longest missteps, of over 13 years of e-mail management R&D (as of Jan 2015). More than 20,000 organizations have installed Cerb over the years, and the project today represents a fusion of the brightest feedback from that community and the vigilant custodianship of a dedicated development team.
