We exist to help you make better outbound contact, using Twilio Flex and/or the Twilio tech stack.

4flex is a set of easy-to-configure plugins and APIs built in collaboration with Twilio, that help you meet specific functionality needs.

We also offer consulting and development services to help you ensure a smooth transition to Twilio-powered outbound.

Auto Dialing & Data Management

Power through your leads with our intelligent predictive dialer, or design more precise nurturing strategies with our preview or progressive dialers.

Plus, ensure that you're making the right contact at the right time in each stage of the sales life cycle.

Automatically deduplicate inbound form entries, and push them to the front of the queue to dial. Then, set up dialing strategies for existing data, to ensure you make the perfect call at the perfect moment.

Complete Compliance

Stay fully compliant with relevant state, country, and continent regulations when making outbound contact.

4flex can help you create compliance rules that meet the needs of your specific organization.

Limit over-dialing while maximizing outbound effectiveness - with 4flex.

Scripting, workflow, and UI solutions

Keep agents on message, without relying on clunky external programs.

Instead, guide your users through each conversation dynamically - integrating customer data into the user interface, with 4flex CallGuides®.

Alternatively, use custom-built Flex or non-Flex interfaces in conjunction with 4flex APIs to handle dialing and data management.
