Przed i Po

Who Is This For?
Service Companies
Agencies, consultancies, accounting firms — drowning in spreadsheets and manual processes.
Manufacturing Companies
Managing orders in spreadsheets, no CRM, zero process automation.
Startups & SaaS
Need an MVP in weeks, not months. System from scratch, without hiring an IT team.
Excel-Dependent Companies
You know Excel is holding you back. You want to turn it into an app, but don't know where to start.

Your Business Outgrew Excel.
But alternatives cost a fortune.
Scenario 1: Business On Excel
47 spreadsheets, 12 macros, and you pray nobody deletes a formula. Clients wait for emails because your "system" is Outlook + Excel + hope.
Result: 20h/week on manual work. Errors. No scaling.
Scenario 2: In-House Dev Team
3 developers, €40k/mo, MVP still broken after 9 months. "We need 2 more sprints" — you've heard that for 6 months.
Result: €350k spent. Product that "almost works". Team that keeps asking for more time.
There's A Third Way
1 engineer who understands tech, design, and business — builds your system from scratch, in 8 weeks, for a fraction of a dev team's cost.
Not outsourcing. Not an agency. A technology partner who delivers a finished product, not hours.
I Couldn't Find A Partner
Who Could Do It All.
I'm Paweł Paruzel. 15 years through the whole path: graphic → UI/UX designer → product designer → frontend developer → B2B sales.
Worked with 300+ companies. From small biz to corpos. Always saw the same issue: marketing is either expensive (€9k/mo agencies) or crap (freelancers who vanish after 2 months).
When I needed marketing for my own ventures, I couldn't find anyone who:
• Does it all (content + video + tech + strategy)
• At a sane price (not €9k)
• With real quality (not "coffee posts")
AI changed the game. Suddenly I could build a system serving clients like a 6-person team, but costing like 1 freelancer. It wasn't a choice - it was obvious.
Syntelligence is the firm I'd want to hire myself. That's how I know it works.
Why 1 Engineer > A 6-Person Team?
I Code It Myself
React, Vue.js, Node.js, databases, APIs. Zero outsourcing. I know what's possible, what takes a day vs a month, and what it really costs.
I Design It Myself
15 years in UI/UX and product design. Wireframe → Design → Code — no middlemen. The system looks good and works good because the same person does both.
I Understand Your Business
300+ projects. I know you want a system that works, not slides in meetings. That's why I build solutions, not presentations. And deliver in weeks, not quarters.
How It Works?
No magic. A proven process we repeat for every client. Each step ends with a concrete deliverable.
