Sippy

Sippy is a WhatsApp-based payment service that enables users to send and receive digital dollars using phone numbers.

A transfer arrives in seconds. What comes after can take days.

Someone has to match it to the right request, get the approval, pay the people involved and file the receipt. That work usually ends up spread across a chat, a spreadsheet, an email and a bank portal, and someone rebuilds it by hand.

We’re building Sippy to coordinate it in one place, with a person approving every payment. How many tools does your team use between the request and the receipt?

SIPPY SPOTLIGHT | ETHEREUM CARTAGENA 🇨🇴

As part of our @EFetheverywhere roadmap, we hosted a Spotlight in Cartagena to present @SippyLat, a product of Cartagena Onchain built by talent from Colombia’s Caribbean region, with a team across Barranquilla and Cartagena.

Sippy has been gaining recognition at @ETHGlobal, where it was featured among the highlighted projects at the Lisbon edition.

Now, we’re bringing the technology to businesses in our region to understand their needs and explore how Sippy can solve real operational challenges.

During the Spotlight, we presented:
🔹 Sippy Personal
🔹 Sippy Business
🔹 Sippy Connect

Different experiences designed to adapt to different users, businesses and operational needs.

But the most important part was the conversation.

We listened to the challenges businesses are facing around payment processes and discussed how Sippy can adapt to their workflows and build solutions around their specific needs.

How much time and team capacity are you currently spending managing payment processes that could be more efficient, automated and traceable?

We’re helping businesses explore how AI agents, stablecoins and automation can be integrated into their operations to reduce operational workload, optimize costs and give their teams more capacity.

Want to explore what this could look like for your business?

Book a call with us and let’s review your operation.

Special shoutout to taqueria la tercera for the amazing catering 🌮.

We just completed our $25K @Arbitrum DAO grant 🎉

What started as a hackathon project is now a live product: a simple way for people to receive, hold and send USDC through chat.

Here’s what we built and learned ↓

[Sippy @SippyLat]

Our biggest lesson: people love receiving money with Sippy, and recurring use needs recurring payments.

Next, we’re testing the experience with organizations that pay people across Latin America.
