Hi. I'm Nahim.
I spent my career doing the VAT work this product now drafts. I built Kehai to turn relentless cross-border VAT/GST change into clear, business-specific, source-backed action.
Kehai (気配) is the Japanese word for a sensed sign that something is about to happen: the shift in the air before it rains. It's almost a literal description of regulatory horizon-scanning.
Panellist, 'VAT Risk in the Instant Payments Era', Uniglobal 8th Annual VAT Management Summit, London, June 2026. Event details
The problem I kept living
I've led indirect tax across 45+ jurisdictions in EMEA, the Americas and APAC (VAT, GST, US sales tax and customs), through ERP transformations, multiple post-merger integrations, and the daily reality of keeping a 200-plus-return footprint under control. The hard part was never finding the change. It was the work after: whether it actually affects the business, why, who owns the response, by when, and proving the source behind every position. That judgement layer lived in inboxes, spreadsheets and people's heads.
So I built the tool I always wanted
Kehai scans the jurisdictions that matter to you, flags the high-impact changes, frames the business-specific impact, and ties every claim to a verifiable source. Monitoring built for the decision, not the inbox.
A tax engine absorbs a rule change into its calculations. You never see it. Kehai has no engine to absorb anything, so every change that touches your footprint reaches you: owned, dated, and backed by its source.
Indirect tax at global scale
VAT, GST, US sales & use tax and customs across 45+ jurisdictions; M&A and post-merger integration; audit defence; operating-model design; recoverability and operational visibility.
Tax technology
ERP and tax-engine programmes, e-invoicing and digital reporting (France, Italy SDI, MTD, SAF-T, DAC7, CESOP, ViDA), governance aligned to SOX.
And I build
Production AI tooling and web apps (Next.js, React, Claude) that take the manual load off compliance. Kehai runs on that same stack.
A builder at heart
I'm a strategist and a builder at heart, happiest where systems, people and purpose meet. I'm relentlessly curious, and I like designing tools that make hard things feel clear. Outside work you'll find me training (karate black belt, boxing, HYROX) and bringing the same discipline to everything I make.
The pilot, plainly
Why only five partners
Because attention does not scale like headcount. Each partner gets the product configured to their footprint and a direct line to the person who builds it; five is the most that stays honest.
What partners get
Kehai set up for your markets, free for 90 days, and a real say in what gets built next. In return: structured feedback and, if you are happy, permission to be named as a reference.
Who does the reviewing
Your own team. The agent drafts the assessments; your named reviewers approve, reject or turn them into owned actions, and every sign-off is recorded in the audit trail. I never review your items for you.
Continuity and your data
Monitoring runs on a schedule, not on my laptop. Your workspace and data live on EU infrastructure, and every item's evidence pack is exportable, so nothing is locked in.
Every claim shows its source, and the distinct trust signals (official source, claim support, reachability, human review) are never collapsed into a single tick.
Book a consultation
Leave your work email and I'll set up a consultation scoped to your jurisdictions, entities and flows.
