YieldStack's answer
AI integrations supporting the platform’s workflows.
Abelo's answer:
Abelo is a cloud-based SaaS platform with a REST API and webhooks, documented at docs.abelo.ai. It connects natively to Shopify, WooCommerce and Magento, and delivers Viber messages directly as an Official Rakuten Viber Messaging Partner. Built by Trebbble's in-house engineering team, with enterprise-grade security and GDPR compliance.
YieldStack's answer
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
Abelo's answer:
Abelo is both the messaging provider and the intelligence layer. Businesses usually have to choose between a provider that delivers messages but cannot target or measure them, and a marketing tool that relies on someone else's delivery. As an Official Rakuten Viber Messaging Partner, Abelo delivers Viber messages directly under the business's own verified name, and builds segmentation, personalisation, automation and ROI tracking on top. Personalisation reaches the image, the button and every card in a Viber carousel, not just the text. Promotional messages triggered through the API report as named campaigns, with the same tracking as campaigns sent from the platform. Delivery and intelligence, on one contract.
YieldStack's answer
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
Abelo's answer:
Because most messaging platforms stop at "delivered". Abelo shows what each campaign earned: revenue, orders and cost per sale tracked to every campaign and automated flow when sales data is connected, plus delivery, opens, clicks and cost on everything. It's an Official Rakuten Viber Messaging Partner, so Viber messages go out directly with no reseller in the chain, and anything that can't be delivered on Viber or WhatsApp is re-sent as SMS automatically. Marketers launch campaigns without a developer, developers trigger messages through one REST API, and online stores on Shopify, WooCommerce or Magento switch on pre-built revenue flows instead of designing them. One platform, one contract, one bill.
YieldStack's answer
Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.
Abelo's answer:
Two groups. Marketing and eCommerce teams at retailers and online stores, such as CMOs, CRM managers and eCommerce directors, who use Viber, WhatsApp and SMS to turn their customer base into more orders. And digital, IT and operations teams at enterprises such as banks, insurers and logistics companies, who depend on messages that must arrive: one-time passwords, transaction alerts, delivery updates and payment reminders. Both use the same platform: marketers through the web app, developers through the API.
YieldStack's answer
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
Abelo's answer:
Abelo is built and owned by Trebbble, a design and engineering company that has shipped mobile and digital products for banks, telecom operators and energy providers since 2010, and has always been self-funded. Abelo started as VibeCart, a Viber marketing platform for online stores. Building it, the team saw the same gap again and again: businesses had to choose between a messaging provider that delivers but can't measure, and a marketing tool that measures but rents someone else's delivery. In July 2026 VibeCart became Abelo, and Abelo became an Official Rakuten Viber Messaging Partner. The platform now covers transactional messaging and enterprise use cases as well as eCommerce, across Viber, WhatsApp and SMS.
