Thank you for your interest! DealMaker does not offer a marketplace of offerings as we are a back end software for companies to use in closing their offerings. In order for you to be able to invest in deals on DealMaker you have to be invited by the company. Some companies might have a public link posted online that would give you access to the deal.
If there is a particular offering you are interested in we recommend you get in touch with the company you wish to invest in for further information.
