Customer.io

Customer.io is a powerful automation platform designed to help you send relevant messages based on how people interact with your product. Instead of sending generic blasts, you can trigger personalized emails, SMS, and push notifications when users perform specific actions.

You can manage complex messaging workflows using a visual builder that maps out the entire customer journey.

It is particularly effective for SaaS companies and mobile apps that rely on real-time user data to drive growth and long-term loyalty.

Flowcode

Flowcode helps you bridge the gap between your physical marketing and digital experiences. You can create custom, brand-aligned QR codes that scan instantly and direct your customers to curated mobile landing pages called Flowpages. These tools allow you to collect contact information, share social links, and drive conversions directly from a physical touchpoint like a product package or storefront.

You can manage your entire offline-to-online strategy from a single dashboard where you track every scan in real-time. This data gives you deep insights into customer behavior, allowing you to see exactly where and when people are engaging with your brand. Whether you are a small business owner or part of a large enterprise team, the platform provides the tools you need to turn passive viewers into active digital customers.
