After – With CallSine
Hi David,
Saw on LinkedIn that FinTechOS recently launched in the US market to expand its embedded finance solutions. With this growth, I imagine scaling sales outreach to meet growing quarterly sales targets whilst maintaining engagement highly personalized is becoming a challenge.
At CallSine, we recently helped QuikPay amplify their outreach across LinkedIn, email, and SMS—automating personalized messages that reference a prospect’s funding news, product expansion, or latest industry shifts, or a combination of all three. By leveraging this data in their messaging, they skyrocketed both their outreach volume and engaged conversations.
Imagine in a click being able to reach out to enterprise clients by referencing their own regulatory approvals, partnership announcements, or market trends, making your outreach feel less like cold sales and more like an industry conversation. At scale.
Would love to share how we’re helping fintech companies like FinTechOS increase response rates while reducing manual outreach. Open to seeing our deck?
Best,
Sarah
