Business intelligence · made human
Grainstack connects to your existing business data and answers your questions in plain English — then hands those answers to BI Slate, which turns them into polished, board-ready PDF reports. No spreadsheets. No waiting.
The reporting problem
Most businesses are sitting on a goldmine of information — sales figures, stock levels, customer patterns — locked inside systems that don't talk to each other and don't answer questions.
Getting a single number often means calling someone, waiting for a spreadsheet, or building a report by hand. By the time you have the answer, the decision has already been made.
Someone has to pull the data, format it, check it, and send it — every single time.
Your sales system, accounting software, and stock manager don't speak the same language.
When your manager asks "how did we do last month?" the answer shouldn't take a week.
Raw data in a spreadsheet doesn't tell a story — and it doesn't impress a board room.
How it works
Grainstack sits between your data and your decisions. You ask a question in plain English. It finds the answer from your live business data. Then BI Slate takes over — composing that answer into a pixel-perfect PDF report, automatically.
Grainstack connects securely to your existing business systems — accounting, sales, stock. Nothing moves or migrates. Your data stays exactly where it is.

Western Cape recorded the strongest quarter-on-quarter growth at +31%, driven by Enterprise Licence uptake. Gauteng remained the dominant revenue region. KwaZulu-Natal recovered from a Q4 dip and is trending upward heading into Q2.
Ask from anywhere
Grainstack works across three channels — so your team gets answers in the way that suits them, whether that's a browser, a WhatsApp message, or the AI assistant they already use every day.
A clean, browser-based workspace where you ask questions, explore answers, and kick off report generation — from any device, anywhere in the world.
Connect your WhatsApp Business number and your team gets answers by message — no login, no app, no friction. Works on any phone your team already carries.
If your team already uses an AI assistant, Grainstack plugs straight in. Your business data becomes a live source it can query — no copy-pasting, no stale exports.
Your data is safe
Grainstack connects to your data the same way a read-only analyst would — it can see and query your data, but it cannot change, delete, or write anything. Ever.
Your data never moves. Nothing is copied to an external server. Every connection is encrypted and authenticated end-to-end.
Write access is explicitly blocked at the source — forbidden at the database level, not just switched off.
Every connection between Grainstack and your data is encrypted end-to-end. No plain-text data in transit.
Grainstack runs on hardware you control. Your data never leaves your environment to answer a question.
Each workspace is fully isolated — separate credentials, separate access. One client can never see another's data.
Information flow — end to end
"A grain stack is where raw harvest is gathered, layered, and stored before it becomes something useful. Grainstack does the same for your data — collecting every grain of signal and stacking it into intelligence you can act on."— Grainstack · grainstack.ai · 2026
