Work is the easy part.
Life is what’s left.
That is the idea we started from: making things was never the bottleneck. What the making eats is the evening, the weekend, the attention you owe to people who aren’t your inbox. So we built a workspace that takes the execution and hands the judgement back. AI drafts; a person with a name decides. We build what we sell, and it is us you meet on the call.
Sixty-seven tools. None of them signed off.
Most commercial teams didn’t adopt AI. It arrived one tab at a time, on personal logins, with nobody’s name on the output. Fast, ungoverned, and quietly terrifying to anyone who has to answer for what ships.
We’re here for the person holding that bag: the marketing, sales or support lead who is on the hook for the work, the brand, and now the machines. Tisser gives them one governed door instead of sixty-seven open tabs.
We were AI Opener. Then we found a better word.
We started as AI Opener, building the governed environment where AI does real commercial work. The engineering was right; the name only said what we did, not what it felt like when it worked.
tis·ser (French, verb)
To weave: many separate threads pulled into one finished cloth, which is exactly what a team of agents does under one brand memory.
Say it out loud in Dutch and it becomes ’t is er: “it’s done.” Both meanings, one word. When the work is finished, there’s nothing left to announce. Just: Tisser.
AI drafts. A named human decides.
Plenty of companies will sell you AI that acts on its own. We think that’s the part they’ll regret. At Tisser the machines do the drafting; a named person does the deciding. Nothing Tisser publishes or sends goes out before that person approves it, and the approval is logged with their name on it. It’s the shape of the product.
Control 1
Brand contract
The agents work from one agreed record of how you sound, what you claim, and what you never say.
Control 2
Publish gate
Nothing ships until a named human approves it. The gate is a person, not a checkbox.
Control 3
Audit trail
Every step is logged, with who and when, so the work can be explained after the fact, not just trusted before it.
Control 4
EU data residency
The platform runs in EU datacenters. Your prompts, outputs and brand sources stay in the EU.
The accountability isn’t optional anymore.
Since 2 August 2026, the EU AI Act’s transparency duties (Article 50, Regulation (EU) 2024/1689) land on the team that publishes AI-made work, not on the vendor that made the tool. Get it wrong and the exposure runs to €15M or 3% of global turnover (Article 99(4)). The exemption the law leaves you is, in effect, a person: a named human who reviews and holds editorial responsibility.
Founder-led: the people who sell it build it.
A Dutch company, not a hyperscaler. The people who position Tisser are the same people who build and install it, so a call is thirty minutes with a founder, not an SDR.
