There is a short window after a prospective client first reaches out during which they are still actively comparing options. Research consistently shows that the first vendor to respond with a credible, personalised proposal wins the deal at a significantly higher rate than those who follow up days later. Kaissa.nl's AI proposal engine is built entirely around capturing that window.
A traditionally written proposal for a mid-size digital project takes between four and eight hours to produce. That includes research, scoping, writing, formatting, and internal review. Even at the fast end, you are looking at a same-day turnaround only if the proposal is the only thing on your plate — which it never is.
The result is that most agencies respond to new inquiries in two to three days. By that point, the client has had three more conversations with competitors, attended two discovery calls, and mentally moved on from the excitement of their initial inquiry.
Kaissa.nl generates a full proposal draft in under five minutes by combining two things: a live crawl of the client's website and Claude AI's ability to synthesise that context into a structured document. The crawl pulls the client's business context — what they do, how they position themselves, what their digital presence looks like, and where the obvious gaps are. Claude then writes a proposal that speaks directly to that context.
The structure every Kaissa.nl proposal follows:
This structure is consistent across every proposal, which means clients always know where to find the information they need. Consistency builds trust faster than novelty does.
One of the more underrated aspects of the AI generation layer is tone adaptation. Kaissa.nl reads industry signals from the crawled website — sector, company size, communication style — and adjusts the proposal language accordingly. A proposal for a legal services firm uses measured, formal language. One for a growth-stage startup uses sharper, more direct framing. The difference is meaningful: a proposal that sounds like it was written for someone else gets dismissed faster than one that feels tailored.
You can further tune this by uploading your own context files to the platform — rate cards, case studies, service descriptions, or tone guidelines. These files are incorporated into the generation prompt, so the AI writes with your voice, not a generic one.
Speed getting the proposal out is only half the equation. The other half is what happens after the client receives it. Kaissa.nl hosts every proposal at a dedicated subdomain — {slug}.kaissa.nl — that loads instantly on mobile and desktop, requires no login from the client, and tracks engagement automatically.
When a client opens your proposal, you get a WhatsApp notification. When they scroll through it, that is tracked too. When they respond — accept, decline, or request changes — you are notified immediately and can act from your phone in seconds. The time between "client read the proposal" and "you responded" shrinks from hours to minutes.
The other thing speed enables is volume. When proposals take eight hours each, you can realistically send two or three a week before it crowds out delivery work. When they take five minutes each, you can send fifteen — and still spend the bulk of your time on the client work that actually generates revenue.
Higher volume at consistent quality is not just good for growth. It changes your posture in sales conversations. When you know you can follow up any meeting with a proposal before the client gets home, you stop treating proposals as scarce resources. You send more. You experiment with positioning. You learn faster what resonates.
The Kaissa.nl dashboard tracks proposal conversion rates by status — how many proposals move from Sent to Viewed, from Viewed to Accepted, and from Accepted to revenue. Over time this data tells you what proposal types convert, which client segments respond fastest, and where in the process deals stall. That feedback loop is only available when you have enough volume to draw conclusions from, which is exactly what five-minute proposals make possible.
