Flowcart
Abelo (formerly VibeCart) turns Viber and WhatsApp into a 24/7 revenue engine for your online store. Instead of emails that get buried and SMS that gets ignored, your offers land where customers actually read them โ their chat apps โ with open rates up to 98% and conversions 5โ10x higher than email.
Built for e-commerce, Abelo connects to Shopify, WooCommerce, Magento, or any custom platform via API, then uses your real-time store data to send the right message to the right customer automatically. Recover abandoned carts, launch flash sales in minutes, announce new arrivals, win back churning shoppers, and reward your best buyers โ all personalized with names, tailored discounts, and product recommendations that feel handwritten.
AI does the heavy lifting. Generate campaign copy and visuals in seconds โ no copywriter, no designer, no guesswork about who to target. Segment customers by purchase history, browsing behavior, order frequency, and spend, then let automated flows run on autopilot: cart recovery, post-purchase upsells, back-in-stock alerts, and win-back offers that sell while you sleep. And you always know what's working. Every message, order, and conversion is tracked and attributed in real time โ revenue generated, messaging costs, ROI, and customer health at a glance. No more wondering whether your marketing pays off; you see it, down to the euro.
Abelo is purpose-built for Greece and Southeast Europe, where shoppers live on Viber and existing tools fall short. If you run an online store and want more sales with less effort, Abelo is your always-on sales and marketing agent.
Quick setup. Zero manual effort. 100% ROI tracking.
Nullstack AbeloAbelo's answer:
VibeCart is the first sales and marketing platform built specifically for selling on Viber and WhatsApp โ the channels where Southeast European shoppers actually live. Most tools treat chat as an add-on to email; VibeCart is chat-native. It reads your store data in real time and acts as an autonomous sales agent, automatically running cart recovery, product launches, and personalized campaigns that convert 5โ10x better than email or SMS. AI generates the copy and visuals, and every order is attributed in real time โ so it does the work of a full marketing team with zero manual effort.
Abelo's answer:
Channel, automation, and proof. Competitors push email and SMS โ channels with ~18% open rates and rising fatigue. VibeCart puts you on Viber and WhatsApp, where open rates reach 98% and messages actually get read. It's autonomous: AI writes the copy, segments your audience, and runs flows on autopilot, so you don't need a copywriter, designer, or extra staff. And every euro is tracked โ real-time ROI attribution shows exactly what your marketing earns, so you never have to guess. It's purpose-built for Greece and Southeast Europe, not a US tool awkwardly translated.
Abelo's answer:
Small and mid-sized e-commerce stores in Greece and Southeast Europe (Bulgaria, Serbia, Romania) running on Shopify, WooCommerce, or Magento โ merchants whose customers use Viber and WhatsApp daily but who are stuck with email and SMS tools that under-deliver. Typically store owners and marketing leads who want more revenue without hiring more people, across fashion, health & beauty, electronics, home & garden, pharmacy, pet supplies, food & beverage, and more.
Abelo's answer:
VibeCart was born from a clear gap. Across Southeast Europe, 110,000+ e-shops rely on Viber as the everyday way they reach customers โ yet every marketing tool on the market ignored it, forcing merchants into email and SMS that shoppers tune out. Built by Trebbble, an Athens-based product company, VibeCart set out to turn the region's favorite chat apps into a 24/7 revenue engine for online stores โ giving local merchants an autonomous, AI-powered sales agent that levels the playing field with the big players. The mission starts in Greece and expands across the Balkans.
Abelo's answer:
VibeCart integrates with the Viber Business Messages API and the WhatsApp Business Platform (Cloud API), connects to e-commerce platforms via the Shopify, WooCommerce, and Magento APIs (plus custom platforms via API), and uses AI/LLMs for campaign copy and image generation. Core stack is GCP.
