"Flawless Multi-Resort Deployment with a Responsive Full-Stack Platform"

4.5/5

What do you like best about Granton Advertising?

Their engineering team pulled off a complex, multi-location deployment across eight premier resort properties on an aggressive three-month timeline. They delivered a highly responsive full-stack architecture built with React.js, Node.js, and PostgreSQL. By implementing a strongly typed GraphQL API layer, they eliminated data over-fetching at our retail terminals and event booths. They also integrated OpenAI's GPT API and LangChain workflows into an automated WhatsApp customer-intake framework, which streamlined our guest data ingestion end to end.

What do you dislike about Granton Advertising?

There was very little to criticize about their execution overall. The only meaningful friction on the project came from the technical limitations of our legacy hospitality software, Micros-Fidelio. Trying to integrate custom GraphQL middleware with such a rigid legacy environment created complicated data-synchronization bottlenecks. Even so, Granton’s team navigated these constraints smoothly, building a custom platform that allowed us to phase out the legacy system entirely while still keeping to a disciplined deployment timeline.

Recommendations to others considering Granton Advertising:

If you’re dealing with complex, multi-location integrations or need to phase out rigid legacy software, Granton’s engineering team stands out. Their ability to deploy cutting-edge AI orchestration layers like LangChain and OpenAI, while also delivering robust full-stack architecture, makes them a premium partner for enterprise work.

What problems is Granton Advertising solving and how is that benefiting you?

We needed to unify fragmented guest data across eight distinct resort properties so we could connect physical, on-site spending with our digital marketing retention efforts. Granton engineered an AI-driven pipeline that captures real-time data telemetry from resort check-ins, dining, and event booths, bringing those signals together in one place. As a result, we can more accurately predict low-occupancy windows, dynamically adjust room pricing based on market trends, and run automated, hyper-targeted promotional email campaigns to regular customers at the moments we most need to fill rooms.
