You want more booked appointments and qualified leads. We care about which AI gets you there.
ALEX is built on frontier AI from Anthropic, OpenAI, Google and more — continuously benchmarked and updated. You do not chase AI trends. That is our job.
ALEX uses frontier models from Anthropic, OpenAI, and Google — fine-tuned for the window and door industry. ALEX understands your terminology, handles objections, and follows your sales playbook every time.
No lag, no delays. ALEX responds in under 15 seconds — faster than any human sales team, at any hour of day or night.
When new AI models launch, our team benchmarks them for your use cases and upgrades ALEX automatically. You always have the best performing AI without doing anything.
We test technology from the world's leading AI companies — tuned for window and door dealers.
Most competitors say AI-powered but picked one model years ago. At Number 44, we treat AI as a product, not a checkbox.
We continuously invest in testing and improving our AI stack every month.
We test new models as they release so you never fall behind.
We deploy only what delivers higher qualification rates and more booked appointments.
