We are testing new lead channels for our B2C fintech call center. We want to partner with high quality lead generation businesses that run their OWN call centers (e.g. selling multiple products) who could cross-sale/downsell our product and do warm transfers into our call center. Pretty broad customer demo target. Would pay CPL or CPA back to lead generator. Who are the best firms we should talk to in this space?
Also open on any best practices you know when selecting a partner.
This would really depend on your goal of the lead channel. If you want to deal with warm leads give http://inspirebeats.com a try. InspireBeats will help you find and build a list of targeted leads, do research on them, and warm them up for you through a personalized outreach. That way you have an additional channel of leads flowing in for your sales reps.
