JS&P

Work & solutions

We build to learn. We prove before we promise.

The products, cases and prototypes of JS&P are not isolated technical experiments. They show how we translate bottlenecks in a commercial or human chain into a tangible solution — with clear sources, human control and evidence per development stage.

Each case names the chain problem, the links involved, the intervention and the honest evidence status.

Sales Insight

More relevant B2B follow-up, with context and human control.

Sales Insight researches public company information, orders the relevant signals and produces a proposal for personal B2B follow-up. The user reviews and decides. The product is designed as a focused workflow, not a mass-mailing tool or a replacement for the CRM.

  • translation of senior sales logic into software
  • a focus on relevance over volume
  • human review and audit trail
  • integration direction for Salesforce and existing sales processes
Chain problem: generic acquisition and insufficient account context.
Links involved: market analysis · business intelligence · sales management · acquisition.
Intervention: a verifiable workflow that turns public company context into personal account preparation.
Role of technology: structuring information and speeding up preparation; the user reviews and makes personal contact.

Evidence status: the core and tests are internally validated. External Salesforce-org validation and market validation remain separate release gates.

Nexus Quattro Control

A cockpit for serious AI work.

Nexus Quattro Control brings projects, context, AI routes, tasks, approvals, files and results together in one macOS environment. It's built for people who don't want to use AI as a loose chat, but as a controllable part of their work.

  • translating complex AI workflows into a calm user experience
  • subscription-first thinking: existing AI subscriptions come first
  • safe tasks and explicit approvals
  • bringing results back to project files and evidence
Chain problem: fragmented information, unclear ownership and insufficient control in complex projects.
Links involved: business intelligence · sales management · project direction · handover to execution.
Intervention: one controllable cockpit for context, tasks, approvals and results.
Role of technology: AI and automation under explicit human approval; nothing proceeds without control.

Evidence status: the build, runtime tests and DMG are internally validated. The full human must-pass demo and the final distribution choice remain release gates.

AiCafe

Multiple AI perspectives. One usable outcome.

AiCafe makes collaboration between different AI systems understandable. The user asks the question, chooses the participants and keeps control. The systems build on each other's perspective and finish with a shared proposal, solution or super-prompt.

  • reducing complex technology to a recognisable metaphor
  • user control instead of hidden autonomy
  • native product development for Apple platforms
  • privacy and store requirements considered from the design onward
Chain problem: separate AI tools deliver fragmented output that is hard to assess.
Links involved: business intelligence · decision-making · execution.
Intervention: multiple AI systems work under the user's direction toward one usable outcome.
Role of technology: transparent collaboration between models; the human stays in control.

Simpel Thuis

Making technology understandable at the moment someone needs help.

Simpel Thuis grew from a simple human problem: devices are often needlessly complicated. The concept translates a device and a desired action into large, visual steps that older adults and less digitally confident users can also follow.

  • problem thinking from real users
  • accessibility as the core, not an afterthought
  • a combination of camera, recognition and visual instruction
  • a B2C and care-oriented B2B direction
Chain problem: complex devices don't match the user; adoption and self-reliance stall.
Links involved: design · adoption · customer value (a human chain).
Intervention: translating a device and action into large, visual steps.
Role of technology: camera, recognition and visual instruction; accessibility at the core.
