One industry: doors and windows
Why we focus on this industry, why we work on both the system and overseas growth, how the team is organized, where the product capability comes from, and how we differ from a dev shop.
Going deep in one industry
beats skimming ten.
Doors and windows are made to order. Mullion layout, profile, glass and hardware differ unit by unit, and the same dimensions with a different opening type produce an entirely different bill of materials. Generic management software cannot route around that — its data model has no concept of a window type.
So we didn't take a generic system and bend it to fit window factories. We went the other way: learn how the business actually works, then design the system from that. The chain from drawing to BOM to quote to production follows how a real factory operates, not how a requirements document describes it.
The cost of serving one industry is a smaller market. The benefit is depth that generic software can't reach. We chose the second.
System, growth and AI —
none of them is enough alone.
The real problem is rarely confined to one stage. The best system is useless without customers; and when customers do arrive, slow quoting still loses the order. So we work on all three together.
Door & window software
The foundation for internal efficiency. If drawing, BOM, quoting, orders and production don't connect, nothing upstream can hold an order. This is where we've invested longest.
Overseas growth
Domestic growth has slowed — that's simply the situation. Overseas buyers want what Chinese manufacturing offers; what's missing is the ability to keep finding them and convert inquiries into orders.
AI
AI here isn't a talking point. Drawing recognition, reverse-engineering BOM formulas, customer intent scoring, follow-up scripts — all embedded in daily workflow.
What we do ourselves, and who we do it with.
We don't pretend to do everything in-house. Here is what our own team owns and what long-term partners handle.
Product & engineering
System architecture, CAD workbench, formula engine and AI capabilities are built and maintained by our own team.
Industry knowledge
Profiles, glass, hardware, BOM rules and factory workflow — the prerequisite for designing any of this.
Export & web
Strategy, overseas and multilingual sites, and door & window content are handled in-house.
Partner agencies
Ad campaign execution, regional resources and platform-specific media buying sit with long-term partners.
We have our own product,
not a queue of one-off projects.
The simplest test of whether a company really builds product: does it have something it keeps investing in and evolving. Each of the following can be checked on the spot.
Door & window CAD workbench
Mullion layouts, casement, sliding and folding, arched and irregular shapes, combined and corner units, with 3D preview and top view.
DXF export to AutoCAD
1:1 in millimeters — open it in your own AutoCAD and check the dimensions.
In-house formula engine
Expands the bill of materials from the window type, with custom rules and BOM snapshots.
AI drawing recognition
Reads dimensions and window types from images and multi-page PDF drawings, then lays them out.
This website
Bilingual, per-page hreflang, server-side lead handling — built and maintained by us.
The difference isn't price. It's how the work is done.
A dev shop builds to your specification and stops at handover. A few practical differences in how we work:
A typical dev shop
HaiTu AI
Builds what the spec says, even when the spec is wrong
Looks at how your factory runs first, and says so if the logic doesn't hold
The project ends at sign-off
The product keeps evolving, and rollout includes coaching and review
Relies on you for industry knowledge
We already know the business — you don't teach it from scratch
Either builds software or runs marketing
Builds the system and the acquisition side so the two connect
Says yes to everything
Writes what we can't do directly on the website
HaiTu AI is the door & window brand of Haitusi Network Technology.
