AI-first delivery. Without the vapor.
Senior-architect led. AI-accelerated. Fixed-scope.
Two tracks. One delivery discipline.
Master deck · 2026
THE PATTERN WE HEAR EVERY WEEK
You've seen this before. The project that never ends.
Software delivery keeps slipping. Quotes stretch, scope creeps, and the team you were promised is replaced by juniors learning on your bill.
THE PATTERN, IN THREE SHAPES
Three problems we hear every week.
PAIN 01
Workflow automation that never ships
You paid for custom automation three quarters ago. It's still in 'validation'. Meanwhile your team still exports CSVs and reconciles bank statements by hand.
PAIN 02
Tools that break at every edge
Monday's formula columns don't trigger. Subitems don't sync. Your API hits rate limits. Board changes quietly kill automations. You're managing the tool, not using it.
PAIN 03
Ideas stuck at 'we should build that'
The MVP you need to validate this quarter is sitting in a Figma file. Three dev shops quoted 12 weeks each. By the time it ships, the question won't matter anymore.
HOW WE DELIVER
Two tracks. One delivery discipline.
We don't try to do everything. We do two things, very well.

Workflow Automation
LEAD: ZOLTÁN HÉCZEI · WORKFLOW AUTOMATION
n8n-based automation for mid-market teams drowning in Monday, custom CRM systems, or their own patchwork of tools. We integrate, automate, and give you a clean dashboard over the chaos.

COMMON PAINS WE SOLVE
Specific issues, specific fixes.
- Monday formula columns don't trigger.
- Subitems don't inherit parent logic.
- Board structure changes break automations.
- API rate limits block advanced logic.
- Cross-system data doesn't sync.
And so many more. Let's give you a painkiller.

SCOPE RULES — WE'RE UPFRONT
We only take on what we can ship.
- Greenfield only (no legacy integration).
- Ringfenced (no production data migration).
- Max 2 parallel projects — to keep quality.
- Every kick-off starts with architecture review.
Your sprint starts with a conversation.
HOW WE'RE DIFFERENT
We've rebuilt delivery from the ground up.
PILLAR 01
3–5× faster, honestly
AI-accelerated delivery compresses the work — but not the quality gates. A 12-week engagement becomes 3–4 weeks.
PILLAR 02
Human in every loop
No AI-generated code reaches you without senior architect sign-off. Every project has architecture review, QA gates, and a human-approved handover.
PILLAR 03
Fixed scope. Fixed price. Fixed date.
Time & Material is how agencies protect themselves at your expense. Fixed-scope contracts — you know the price and delivery date before you sign.
WATERFALL IN DISCIPLINE. AGILE IN FEEDBACK.
Five steps from brief to deployed.
01 · BRIEF
Brief
A single hour scoping call. You leave with a one-page summary of what we heard.
02 · PRD
PRD
We write the product requirement document. You approve it — or send it back with edits.
03 · AUDIT
Audit
A senior architect stress-tests the plan for scale, security, and compliance before any code is written.
04 · BUILD
Build
AI-accelerated development with architect oversight. Every merge is human-approved. Daily progress, not monthly reports.
05 · DELIVER
Deliver
Production-ready code, documented, tested, deployed. Handover session included.
WHERE WE'VE SEEN THIS PATTERN BEFORE
Where we've seen this pattern before.
Industries where workflow chaos compounds fast, or where a validated prototype beats a 12-week spec.
Hospitality & Travel
Multi-property operations, daily reconciliation, guest data flows.
Construction & Real Estate
Project tracking, site-to-office data, document automation.
eCommerce & Retail
Order fulfillment, inventory sync, returns and reporting.
Sales Ops & CRM
Monday, custom CRM systems, or patchwork tools — when the stack becomes the bottleneck.
Scaleup SaaS
Greenfield MVPs, product experiments, validation sprints.
Professional Services
Billing logic, client ops, compliance reporting.
PROOF OF WORK
TRACK AMID-MARKET HOTEL GROUP
Five banks, reconciled by 9 AM.
Every morning their finance team manually matched transactions across five bank accounts against the PMS. Four hours of work, seven days a week. We automated the match + import pipeline. Now it runs before the night audit closes.
4 hours → 15 minutes · Shipped in 2 weeks
PROOF OF WORK
TRACK ACONSTRUCTION COMPANY
Six years of Monday data, made useful again.
6,000+ active tasks across 40 boards — structure drift, dead automations, no way to find what mattered this week. We used n8n + AI to restructure the full task history and auto-insert next-action prompts back into Monday.
6 years re-structured · Live in 3 weeks
PROOF OF WORK
TRACK BSCALEUP FOUNDER
Tested the concept before the board meeting.
A workflow idea that needed investor validation before the next board deck. We shipped a functional prototype in 4 days — real clicks, real flows, real feedback. The validation sprint decided their Q2 roadmap.

Appendix · More case studies →THE TEAM YOU'LL ACTUALLY WORK WITH
Not juniors on a learning curve.
Five founders, two advisers, one strategic partner — the people you meet are the people who ship. Decades of combined enterprise delivery and entrepreneurial experience.

APPENDIX · THE METHOD
← Back to Delivery ProcessWaterfall in discipline. Agile in feedback.
Linear specification flow: Brief → PRD → Audit → Build → Deliver. Each gate is an explicit approval point — nothing advances without sign-off.
The PRD and Audit stages are where we invest the most deliberate time. By the Build stage, the scope is locked and the architecture is validated.
Inside Build: AI-accelerated code generation, reviewed, tested, and integrated in parallel. Senior architect approves every merge. No AI code reaches the client unreviewed.
Feedback loop runs daily. You see what shipped, what's blocked, what's next — every day. No monthly status reports.
PRINCIPLES
- Measure twice, cut once.
- Single point of failure elimination.
- Quality is never sacrificed to tools or speed.
- No tech debt — we don't leave anything behind.
- Client side of the table.
