Restive

Restive is a digital product and AI consulting firm founded in Melbourne in 2018, with teams across Melbourne, Sydney, Brisbane, Perth and Kuala Lumpur. We help Australia's most ambitious brands design and ship AI agents, commerce experiences and digital products - with a guiding principle of speed without sacrificing quality.

Our dedicated agentic AI practice builds production-grade AI agents for enterprise, including customer-facing voice and conversational agents built on Vapi. We work across three engagement models: Rapid PoC & Product Launch, delivering working software in the first week rather than a strategy deck; AI Transformation & Operating Model, where we embed AI orchestrators, engineers and specialist agent teams directly into a client's organisation to automate processes at scale; and Labs & Joint Ventures, where we co-fund and co-build new AI products with clients on a revenue-share or equity basis.

Our voice and agent work spans multi-agent orchestration, customer-facing voice agents for guidance, sales and retention, internal workflow automation agents, and AI-native product builds- all grounded in our research-driven discovery approach and measured from day one against real business outcomes like time saved, throughput and error rates.

We're trusted by some of Australia's largest and most complex retail, finance and enterprise brands, including Coles, Kmart, JB Hi-Fi, Sportsbet, Tyro and carsales, and we hold partnerships with Google Cloud, AWS, Azure, Anthropic, OpenAI, Snowflake and Databricks. We also bring deep expertise in accessibility (WCAG 2.2), unified commerce and cloud modernisation, meaning voice AI solutions we build are enterprise-ready, accessible and integrated into the broader technology stack from day one.

As a Vapi partner, Restive brings Australian enterprises a proven path from voice AI concept to production - combining Vapi's platform with our delivery track record, embedded operating model and multi-vendor AI expertise.

Restive partners with Vapi to bring production-grade voice AI to Australian companies. Vapi provides the voice AI infrastructure: low-latency conversational agents, telephony integration and the orchestration layer for real-time voice interactions. Restive brings the discovery, design, engineering and change management needed to take that infrastructure from proof of concept to a live, revenue-generating capability inside a client's business.

In practice, our teams use Vapi as the voice agent platform of choice for customer-facing use cases, including sales and retention calls, customer support and service triage, appointment booking, and outbound campaigns, building on top of it with our own agent orchestration, data integration and enterprise-grade guardrails. We combine Vapi's speed to build with our delivery model: a rapid proof of concept in the first week, followed by iterative hardening for scale, security, accessibility and compliance, and integration into the client's existing CRM, contact centre and data stack.

For clients that want to go further, we embed engineers, AI orchestrators and product teams directly into their organisation to operate and continuously improve their Vapi-powered voice agents as part of a broader AI transformation program, measuring success against real outcomes like call deflection, conversion, average handling time and customer satisfaction, not just technical uptime.

This partnership lets us offer Australian organisations the best of both worlds: Vapi's purpose-built voice AI platform, and Restive's track record delivering complex, production-grade digital and AI systems for brands like Coles, Kmart, JB Hi-Fi, Sportsbet and Tyro. Together, we help businesses move from "we should explore voice AI" to a live, measurable voice agent in production, without the typical 87% failure rate that stalls most AI initiatives before they ever ship.
