Interface is one of the cleanest of all project management web apps.
Their lack of communication. For a project management app company, they should be leading the charge in a clear roadmap to the product and communication with their customers. Instead, year after year, promises never happen and the product is stagnant, unless maybe the Enterprise portion is getting all the love. None of the rest of us are. There is still no billing component. Integration is basic. No signs of any development activity. Is it alive? Yes, they drip content once in a while, but beyond that, it feels like a dead product.
Wait until they start to show some action. We held on for years, waiting for each item that we needed and most other platforms had. For the price point, their communication and direction are missing.
Project/business management, pipelining, process management. All the stuff they claim is important to them.
