External CTO, not external freelancer
An embedded technical lead with skin in the game — strategic ownership of architecture, hiring oversight, vendor calls, code review. Not a head-count line item you brief and re-brief every quarter.
For software companies
An external CTO who builds the products you keep selling.
AVANTGARDE partners with founders and product owners to turn their domain expertise into repeatable software revenue. We carry the technical execution. You carry the customer relationship. We split the upside.
How we work
Three principles that decide whether a partnership makes sense.
Revenue share over retainer
We take a smaller upfront retainer and a larger share of the recurring revenue from the products we ship together. The risk is on our side. Your CFO can model the spend.
You sell. We ship.
Founders and product owners stay in front of customers, where they belong. We handle architecture, build, deployment, vendor management, and the tedious half of a Microsoft-365 admin call.
Who we partner with
We don't take every engagement. The fit matters more than the fee.
- Software companies with paying customers in (or adjacent to) the DocuWare ecosystem
- Founders who want to ship more product without doubling their dev headcount
- Teams that can sell — and need someone trustworthy to build behind them
- Senior leaders who want the architect tier, not the agency tier

About Ahmet
Senior software architect. Former DocuWare engineer. Star speaker at DocuWorld 2024.
Ahmet Tas spent 8 years inside DocuWare's Germering headquarters before founding AVANTGARDE in Izmir. He still has a direct line into DocuWare's leadership team — and a fluent grasp of the technical stack most partners can only read about.
He works in German, English, and Turkish. He has built across DACH, MENA, and APAC. What he doesn't do is generic consulting.
If this resonates, the next step is a conversation.
30 minutes. No deck, no NDA paperwork up front. We talk about what you're trying to ship, what's blocking it, and whether a partnership is the right vehicle.
