As part of CrowdHabitat project here you can see its logo. This logo is based on a Free Google font typography called "Bitter". It had to be clean and modern among other features and had to invite the client to use the tool.
Its symbol, the letter "H", invites any investor to come in and know what this platform really does (CrowdHabitat is a new web platform where investors can invest their money in a completely new way)...
Above you can see the final logo on light and dark backgrounds. You can tell how the letter "H", its symbol, looks good on both hues, allowing the logo to be more consistency.
The letter "H", the symbol of the logo, isolated, in order to make sure it looks properly on its own.
Images above show rough sketches of the logo, kind of a visual "brainstorming"; it's an easier and faster way of beginning creating any logo. Beginning by doing this kind of drawings saves lots of time later on in the project because this process will allow you to choose the right ones, and throw away the wrong ones, even before starting to work with digital tools such as Photoshop, Illustrator, or whatever tool one uses.
