ONE LAYER OVER YOUR MARKETING AND SALES

What the brain does for you.

01

Your data, one memory

Campaigns, creatives, results and customer signals come together in a brain that stays yours. Data ownership, no separate island per platform.

02

Remembers what worked

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

Human in the loop

Every action with impact passes a person first, with the source attached. AI that works alongside you, without you losing control.

Connected to the systems you already use, in real-time

THE PROBLEM

You're missing the data that actually matters.

Your systems generate thousands of data points per minute. Without context, it's all noise.

Fragmented channels

The truth is spread across your email, calendar, CRM, ads and bookkeeping. Without connecting them, you're flying blind.

Reporting is a rearview mirror

Dashboards tell you what happened yesterday. Decisions are about what needs to happen tomorrow. Nobody benefits from a 40-page PDF.

Five on reporting, zero on strategy

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

You pay up front, you see it after the fact.

The old way measures afterwards, on a dashboard that is not yours. Stevin flags things up front, on your own data.

Stevin spots it

A notification with the reason and the advice attached. No noise, only what genuinely needs action.

A quick message with a concrete proposal, in plain language. Nothing to decode.

No 40-page PDF.

03

One tap

You or your team approve it. No meeting, no waiting, no email back and forth.

Same day, not next month.

FAQ

Frequently asked questions

What exactly does Stevin do?

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.

Who is Stevin for?

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.

Which platforms do you connect?

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.

How is Stevin different from a dashboard tool?

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.

Is my data safe?

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.

What does it cost?

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.

How quickly am I up and running?

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.

You do the work.
Stevin does the rest.
