Context
Businesses want to answer customers on the channels those customers already use, WhatsApp and the phone, without building their own AI infrastructure. Appyverse is the platform Appiness Interactive built to offer that as a product.
The challenge
Every client needs its agent to behave differently, speak about different products and connect to different systems. The platform had to make that a matter of configuration, while keeping text and voice conversations reliable in production.
How it was built
Configurable agents
Agents are shaped by per-client configuration and custom LLM prompts, so a new client means new settings, not a new codebase.
Channel integrations
The backend connects the WhatsApp Business API for text and a telephony provider for voice to the same agent logic.
Built with AI tooling
Core backend logic, integrations and prompts were developed alongside Claude Code and Google Antigravity to move faster without lowering the bar.
Owning delivery
Beyond the code: client onboarding, demos and technical support, with feedback from those conversations going straight into the roadmap.
