You do the work.
Stop doing it twice.
Every week, hours disappear into admin you've already done before. The same quote, rebuilt from scratch. The same invoice, chased again. The same document, rewritten.
GrivoBlinx builds the tools that make it stop.
You work directly with George Billam, 18+ years in construction and design, and the person who actually builds everything.

Chasing the same things manually

“But aren't there already loads of AI tools out there?”
There are. And most of them are built for everyone, which means they're built for no one in particular. A builder quoting jobs doesn't need the same tool as a law firm tracking cases.
You'd spend weeks configuring something generic, training your team on it, and changing how you work to fit the software. We do the opposite. We understand how you work, then build something that fits around it. No onboarding. No licence. No hoping it sticks.
“You won't be handed to a team. You won't speak to some generic salesperson or software dev. Every conversation, every build, every decision is with the same person: the one who actually understands and has experience of your work.”
George Billam, Founder
The trades, design practices, and construction firms.
The trade business
You're a builder, electrician, painter, plasterer, plumber or joiner. You run on WhatsApp and gut feel. You want your evenings back, not a tech project.
The growing business
You're scaling up and the admin is starting to catch up with you. You need systems, not more staff.
The experienced professional
You've been doing this for decades and you've heard a lot about AI. You want to know what it actually means for someone like you, without the hype.
The hands-on specialist
You run a tight operation and know your trade inside out. You want specific tools for specific problems, not a digital transformation.
Built in the real world.
Used every day.
Built for real businesses. Used in the real world. Not demos, not concepts. Tools that are in active use every day, designed from the inside out.
Bespoke Quoting Generator
Client type
Building contractor / trades business
Team size
Single operator to small team
Stack
Next.js PWA · React PDF · Microsoft Graph API · OneDrive · WhatsApp deep-link · Nodemailer · TypeScript
Problem
Quotes were being built manually every time — copy-pasting from spreadsheets, reformatting for each client, no consistent structure. Hours of admin per week, and still inconsistent output that didn't reflect how the business actually priced work.
Solution
A bespoke form-based app that runs on phone, iPad or laptop. The builder enters job details, their own rates and mark-up percentages, and the quote is calculated in real time. One tap exports a consistently-formatted PDF, auto-drafts the client email ready to send, and generates a WhatsApp message with a direct link to the quote hosted on the builder's own OneDrive — no new subscriptions, no new tools. Just the ones they already have, rolled up and working together with a few clicks.
Result
Hours of quote admin cut to minutes. Same format, every time. Built around how they actually work.
Fee Proposal Generator
Client type
Architecture practice
Team size
6 people
Stack
Next.js · OpenAI API · Google Docs API · TypeScript
Problem
Fee proposals were taking 1.5–2 hours per enquiry. Every one was built from scratch, even for similar project types. The process was inconsistent and depended entirely on who was writing it.
Solution
A tool that takes a short brief input and produces a fully-formatted, client-ready fee proposal in under 15 minutes, trained on the practice's own templates and fee structures.
Result
From 2 hours to 15 minutes. Used on every new enquiry.
Client type
Renovation builder / homeowner clients
Team size
Consumer-facing
Stack
Next.js · Land Registry API · RICS/BCIS data · Stripe
Problem
Builders were spending time on site visits and quotes for clients who had no realistic idea of budget. Jobs were falling through after significant time invested.
Solution
A multi-step renovation cost calculator that gives homeowners a realistic cost range before they call a builder, filtering out non-starters and setting expectations before the first conversation.
Result
Fewer wasted site visits. Clients arrive pre-qualified.
Building Regulation Notes Automation
Client type
Architectural technologist
Team size
Solo practice
Stack
Python · Word API · Airtable · Automation Scripts
Problem
BR notes were being written from scratch for each project: same structure every time, but always dependent on someone remembering every applicable clause. One missed scope change could mean a missed note.
Solution
A document generation system that draws project-specific data to populate a structured BR notes template. Built-in scope parameters determine which notes apply, so nothing is missed and nothing irrelevant is included. The professional still reviews and validates every note. The tool handles the structure; the trained eye handles the judgement.
Result
Consistent, complete BR notes. The systematic part is automated. The professional expertise stays exactly where it should.
Client type
Extension builder / structural contractor
Team size
Consumer-facing
Stack
Next.js · RICS/BCIS data · Regional multipliers · Stripe
Problem
Extension enquiries varied wildly in scope and budget expectations. Contractors were pricing jobs only to find the client had half the budget required.
Solution
An extension cost estimator covering rear, side, two-storey and loft conversions, with regional cost multipliers and spec levels, so contractors and clients reach the first meeting on the same page.
Result
Better-qualified leads. Faster quoting conversations.
Revit / Dynamo Automation Suite
Client type
BIM practice
Team size
12 people
Stack
Dynamo · Revit API · Python · BIM 360
Problem
End-of-stage drawing issues were a half-day exercise: updating title blocks, exporting to PDF, uploading to BIM 360, updating the drawing register. All done manually.
Solution
A suite of Dynamo scripts that handles everything: title block updates, PDF export, BIM 360 upload, and register sync, triggered by a single button press.
Result
End-of-stage drawing issue reduced from half a day to under an hour.
Client type
Developer builder / property investor
Team size
Consumer-facing
Stack
Next.js · Land Registry Price Paid API · postcodes.io · SDLT/CGT calculations · Stripe
Problem
Developer builders were running flip viability on gut feel and rough spreadsheets, missing SDLT surcharges, CGT exposure, and professional fees that killed deals that looked profitable on paper.
Solution
A four-step flip ROI calculator with live Land Registry comparables, full SDLT (including additional dwelling 3% surcharge), CGT at 24%, professional fees, and a confidence score based on comparable sale volume. Produces a £29 Flip Intelligence Report.
Result
Deals assessed in minutes. Hidden costs surfaced before commitment.
These are just some examples. We've also built reporting tools, client portals, RFI systems, and more. Ask us what we've built for your sector.
No fluff. A specific thing, built well.
We keep the process tight. You shouldn't need to commit months of time to get a working tool. Most first builds go from conversation to delivered in under a month.
Discovery
1 hourWe spend an hour understanding how you actually work: your tools, your pain points, your templates. No questionnaires, no sales process, just a conversation. That conversation is with George, not a consultant or account manager. The person who will build your tool.
Scope
1–2 daysWe define a specific, buildable solution with a clear outcome. Not a vague "AI strategy" document. A specific tool that does a specific thing.
Build
2–4 weeksWe build it. Usually 2–4 weeks for a first working version. You get access as it develops, you test it against real work, and we adjust.
Iterate
OngoingMost clients add features or commission new tools after the first one lands. We don't lock you in.
You work with the person who builds it. GrivoBlinx is founded by George Billam, 18+ years in the construction and design industry, and the person who actually writes the code.
No packages. No standard rates.
The first businesses in get First Fix Pricing, locked in for life. The ones who help shape the solution share in what it becomes.
