Systems and methods for shared accounts

A computing system, comprising:

• a network interface;
• a first database structured to store a plurality of accounts of a provider;
• a second database structured to store a plurality of shared accounts containing group member information;
• and
• a processing circuit comprising one or more processors and a memory, the processing circuit configured to:
• receive, via the network interface, a request from a first user device associated with a first member to form a shared account with one or more second members, the request including information for identifying a first account of the first member;
• generate, in the second database, the shared account including a first link between the shared account of the second database and the first account of the first database, wherein the generated shared account includes a unique account number indicating the shared account is accessible by multiple members;
• transmit, via the network interface, one or more messages to one or more second user devices associated with the one or more second members;
• generate one or more second links between one or more second accounts of the one or more second members of the first database and the shared account of the second database, the one or more second links generated according to a response to the one or more messages received from the one or more second user devices;
• establish a value associated with the shared account, the value having a first portion associated with the first account and one or more second portions associated with the second account;
• receive, via the network interface, an input via the first user device indicating a selection to initiate an inbound transfer of a first amount from the first account to the shared account, to increase the value associated with the shared account;
• detect that the value associated with the shared account satisfies a threshold criteria;
• identify an eligible member from among the first member and the second member responsive to the value satisfying the threshold criteria and according to at least one machine learning model that considers financial transaction information of each linked second member;
• transmit, via the network interface, a notification to the user device of the eligible member, the notification indicating availability of an outbound transfer from the shared account to the account of the eligible member;
• receive, via the network interface, a response from the user device, the response selecting to initiate the outbound transfer from the shared account to the account of the eligible member;
• and
• initiate the outbound transfer in an amount specified in the response from the shared account to the account of the eligible member.

A non-transitory computer readable medium storing instructions that, when executed by one or more processors of a processing system, cause the processing system to perform operations comprising:

• receiving, via a network interface, a request from a first user device associated with a first member, the request to form a shared account with one or more second members, the request including information for identifying a first account of the first member;
• generating, in a first database, the shared account including a first link between the shared account of the first database and the first account of a second database, wherein the generated shared account includes a unique account number indicating the shared account is accessible by multiple members;
• transmitting, via the network interface, one or more messages to one or more second user devices associated with the one or more second members;
• generating one or more second links between one or more second accounts of the one or more second members of the first database and the shared account of the second database, the one or more second links generated according to a response to the one or more messages received from the one or more second user devices;
• establishing a value associated with the shared account, the value having a first portion associated with the first account and one or more second portions associated with the second account;
• receiving, via the network interface, an input via the first user device indicating a selection to initiate an inbound transfer of a first amount from the first account to the shared account, to increase the value associated with the shared account;
• detecting that the value associated with the shared account satisfies a threshold criteria;
• identifying an eligible member from among the first member and the second member responsive to the value satisfying the threshold criteria and according to at least one machine learning model that considers financial transaction information of each linked second member;
• transmitting, via the network interface, a notification to the user device of the eligible member, the notification indicating availability of an outbound transfer from the shared account to the account of the eligible member;
• receiving, via the network interface, a response from the user device, the response selecting to initiate the outbound transfer from the shared account to the account of the eligible member;
• and
• initiating the outbound transfer in an amount specified in the response from the shared account to the account of the eligible member.
