Hi, I'm Diraj. I'm building Zyntralink — an AI Front Desk for local service businesses — starting with HVAC companies in the Dallas–Fort Worth area.
Why I'm building this
Small service businesses lose money in a very specific way. The owner or lead tech is out on a job. The phone rings. It goes to voicemail. That customer — who might be sitting in a house without air conditioning during a Texas summer, or without heat during a January cold snap — calls the next company on Google.
That's not a marketing problem. That's not a website problem. That's a phone problem. And the tools that exist to solve it — generic chatbots, contact forms, voicemail transcription — don't understand the trades. They treat a gas smell the same way they treat a request for a maintenance tune-up.
I'm building something different: an AI dispatcher that speaks the vocabulary of a specific trade. Right now that's HVAC. Next it's plumbing, then electrical, then roofing. Same engine, different intelligence per vertical.
Why one vertical at a time
Generic products lose to specialists. A chatbot that "works for any small business" knows nothing about anything. A chatbot built for HVAC knows that gas smell means evacuate, that dispatchers schedule by half-day windows not 30-minute slots, that a no-heat call in January is a life-safety emergency and a no-heat call in July is a maintenance request.
So I'm going deep on HVAC first. When I've won that vertical, the same engine will expand — with vertical-specific tuning — to plumbing, electrical, and roofing. The tech is already generic. What each vertical needs is different knowledge, not a different product.
Where I am today
The HVAC product is live and running as of July 2026. I'm talking to family-owned HVAC companies in DFW right now — the first three get 60 days free as design partners, in exchange for feedback and a testimonial. If that's you (or somebody you know), reach out.
The waitlists for plumbing, electrical, and roofing are open. When those verticals are ready, waitlist companies get first access and design partner pricing.
What's next
I'm going to keep publishing here — what I'm building, what I'm learning from HVAC owner conversations, what works and what doesn't. If you want to follow along, check the blog.
