Migrating for speed, simplicity, and partnership
Google Cloud gave us the best service, cost reduction, and most importantly, a trusted ally. That made all the difference. Now that everything runs on Google Cloud, it's easier for engineering, legal, and security. Managing everything under one roof simplifies our work from every angle.

B2C brands often face a persistent challenge: too many customer signals go without anyone hearing, costing businesses revenue and loyalty. Traditional call centers are expensive, inconsistent, and hard to scale. That pain point inspired Callers to build a fully autonomous AI communications platform powered by 24/7 voice and text agents. Callers AI instantly acts on signals like missed payments or form abandonments across channels like voice, SMS, chat, and WhatsApp.
Originally operating across multiple cloud environments, Callers began running into issues as demand accelerated. The team faced challenges with response latency, limited quota visibility, and coordinating systems across providers, which impacted engineering velocity and customer experience.
"Google Cloud gave us the best service, cost reduction, and most importantly, a trusted ally," said Nimrod Ron, CEO. "That made all the difference."
"Now that everything runs on Google Cloud, it's easier for engineering, legal, and security," Ron explained. "Managing everything under one roof simplifies our work from every angle."
The team migrated infrastructure to Google Kubernetes Engine (GKE) and adopted Gemini to power its AI conversations. With the response speed, output quality, and dynamic configuration controls provided by Gemini, Callers found a strong foundation for scale.
With one unified platform, Callers can now iterate faster, deploy more consistently, and scale its AI agents in real time.
Powering dynamic customer conversations with Gemini and Vertex AI
Gemini is the heart of our human-like agents. It delivers the best blend of latency and quality and gives us real-time control to tailor interactions at scale.

CTO, Callers
Callers platform now handles over 250,000 interactions daily, and helps its customers address every task along the life cycle journey of a customer, such as pre-qualifying leads, reviving dormant ones, and confirming event attendance. The core engine is Gemini, which powers natural-sounding voice conversations that operate independently across inbound and outbound channels.
"Gemini is the heart of our human-like agents," said Rennen Chacham, CTO. "It delivers the best blend of latency and quality and gives us real-time control to tailor interactions at scale."
Unlike traditional AI setups, Callers developed a single AI "brain" that retains full customer context across all channels: voice, chat, SMS, and more. This enables personalized journeys across the full life cycle, with key insights automatically routed back into clients' CRMs.
Callers also uses Vertex AI for use-case-specific workflows, including:
- Real-time call analytics and performance scoring
- Voicemail detection and handling
- Data extraction for lead enrichment
- Intent recognition and routing
Latency is critical, and Gemini's "thinking budget" feature gives the team control to adjust mid-call for speed, cost, or output quality. The flexibility to switch models or tune them per customer use case has been a game changer.
This setup also protects human reps from burnout by filtering only pre-qualified leads for live handoff. This boosts connect rates, shortens deal cycles, and ensures reps spend time on high-value interactions.
Scaling with confidence and setting the stage for what's next
Since migrating to Google Cloud, Callers has increased its capacity 30X. It can now support hundreds of thousands of live AI conversations per day without compromising speed or quality.
Clients across sectors have seen measurable results:
- Conversion rates improved by 50%
- Closed deals rose 32% in the first month
- One legal customer recovered over $500K in revived leads
- Outbound call campaign costs were reduced by up to 80%
"Our platform increased connect rates, drove up deal closures, and helped clients recover significant revenue by reviving cold leads with real-time, human-like voice AI," shared Or Aviv, VP Marketing.
"Callers leverages Google Cloud to help our clients make their customers feel seen, heard, and understood," Aviv continued. "That drives better experiences and directly improves customer loyalty and revenue."

The impact isn't just external. Internally, developers now enjoy better observability, faster rollouts, and centralized quota and billing management. Security and compliance teams benefit from clear governance controls under one provider.
Looking ahead, Callers plans to deepen its omni-channel intelligence, expand AI-driven insights, and launch on the Google Cloud Marketplace, making it easier for enterprises to adopt at scale.
Callers is an AI communication platform built to make every customer interaction count.
Powered by one central brain, it connects calls, chats, and messages into a single, intelligent conversation that carries full context across every channel.
From lead qualification and reactivation to support and retention, Callers AI agents engage customers in real time, 24/7, and integrate deeply with CRMs and data systems to drive measurable outcomes like higher connect rates, faster conversions, and stronger loyalty.
