Fragmented channels
The truth is spread across your email, calendar, CRM, ads and bookkeeping. Without connecting them, you're flying blind.
THE AI LAYER OVER YOUR MARKETING AND SALES
Stevin lays a smart layer over all your channels, puts your own data at the centre and sees what needs attention. Then it moves your campaigns with demand. Your data stays yours, ready for whatever AI can do with it.

ONE LAYER OVER YOUR MARKETING AND SALES
01
Campaigns, creatives, results and customer signals come together in a brain that stays yours. Data ownership, no separate island per platform.
02
Stevin keeps track of what every season, channel and hook delivered. Your next briefing does not start from zero, it starts from what was proven to work last year.
03
Every action with impact passes a person first, with the source attached. AI that works alongside you, without you losing control.
WHO IT'S FOR
Not a layer across your whole business. A marketing brain on your own data: paid and owned, connected and yours.
You know there is more to measure, but it never gets connected. Stevin watches 24/7 and flags things early, no report after the fact.
Your spend runs through the agency, so your data and accounts sit there. Stevin pulls your own signals back to you. The agency stays the one doing the work, you keep the visibility. Software, not a second agency.
Performance agencies are everywhere, building brands is another matter. Share of search, brand mentions, direct traffic: the signals that count when you build a brand, on time and connected.
Connected to the systems you already use, in real-time
THE PROBLEM
Your systems generate thousands of data points per minute. Without context, it's all noise.
The truth is spread across your email, calendar, CRM, ads and bookkeeping. Without connecting them, you're flying blind.
Dashboards tell you what happened yesterday. Decisions are about what needs to happen tomorrow. Nobody benefits from a 40-page PDF.
Your people spend half their time digging things up, combining and formatting. The other half waiting on the outcome. Only then does the thinking start.
THE OLD WAY VS STEVIN
The old way measures afterwards, on a dashboard that is not yours. Stevin flags things up front, on your own data.
HOW IT WORKS
Waarom: KNMI hittegolf 32-35 graden voor Midden- en Zuid-NL, strand-bezetting Scheveningen verwacht +120%.
Advies: switch creative naar de aircon-vs-beach-set, +6% Meta en 4k TikTok voor een venster van 5 dagen. Verwacht +3.000 tickets.
Eén tik van de klant of het team. Geen maandrapportage afwachten, geen mail heen en weer. Stevin zet het klaar.
A notification with the reason and the advice attached. No noise, only what genuinely needs action.
Up front, not after the fact.
A quick message with a concrete proposal, in plain language. Nothing to decode.
No 40-page PDF.
You or your team approve it. No meeting, no waiting, no email back and forth.
Same day, not next month.
Stevin sets it live and it shows up on the board. Nothing gets left, nothing disappears in a drawer.
Handled, not forgotten.
BUILT TO WORK
Connections activated, first signals visible. No months-long rollout.
AI signals, you decide. No autonomous actions without your approval.
Built from real practice, not from a lab. Stevin knows the difference between a blip and a structural problem.
Every interaction makes the system sharper. Advice improves the longer you work with it.

FAQ
Stevin is an AI layer across your whole business. A dashboard shows what happened, Stevin sees what is going on right now and takes the next step. It starts in marketing and sales, where it is already proven and delivers results first. There it spots where revenue or margin is leaking away before you notice it yourself. An ad that cost money but returned nothing, Stevin saw it on April 4th, not weeks later in the monthly overview. From that proven starting point, agents are added step by step for the rest of your business, from first customer contact to quote and follow-up. In practice, you notice it first in marketing and sales.
For entrepreneurs, agency owners and in-house marketing teams. The business owner who runs the shop and wants less time lost to paperwork: quotes, missed calls and scheduling run through Stevin, so your hands stay free for the actual work. The agency owner who wants to serve more clients with the same people. The in-house marketing team that wants every euro traceable to results, without dashboards that contradict each other and without losing grip on scattered data.
The systems you already use. From email, calendar, WhatsApp, CRM, quoting and invoicing software and accounting, through to the marketing channels: Google, Meta and GA4, Search Console, Shopify, HubSpot and more. Work with an audience or fans? Then we connect Spotify, YouTube, TikTok and the socials where it happens just as easily. Direct connections, no separate middle layer that can break down. The marketing and channel connections are the most refined, and we add the broader business systems as you run more of your business through Stevin. Does your software not fit in by default, your quoting program or your accounting for example? Then we connect it anyway, without you having to take on an IT project.
A dashboard waits until you open it and shows what already happened. Stevin turns that around: it sees what is going on right now and flags it itself. It monitors continuously, recognises deviations from what is normal for your business (not generic thresholds) and ties a concrete next step to it. A missed call, a quote left sitting, a campaign losing steam: Stevin notices it and brings it to you, you do not have to go looking for it yourself.
Yes. Servers and AI in Europe, no data outside Europe. Every organisation runs in its own sealed-off environment: your customer data stays yours and is visible to no one else, not to us and not to other clients. Want to go a step further? Then it can even run fully on-premise: AI on your own servers, so nothing has to leave your door. Fully in line with the privacy law (GDPR), no external tracking cookies. What applies to one business does not leak through to another.
Fixed monthly prices, matched to your business and the number of connections, starting from a few hundred euros per month. No hidden costs. If you also work with advertising budget, we do not charge any percentage or margin on top of it. Schedule a call for a tailored proposal.
The systems you already run are usually connected within a day, whether that is your email and calendar or Google, Meta and GA4. After that, Stevin needs a little time: in the first weeks it learns what is normal for your business, because without that baseline every signal is just noise. The more it sees, the sharper and more concrete it gets. So do not expect miracles on day one, but a system that week by week gets better at telling a real signal from background noise. In a short call we sketch what is realistic for your situation.
It's not a wonder. It's Stevin.
