Enterprise infrastructure
without the vendor risk.
FW Delta transforms years of high-stakes consultancy into a scalable structure for sovereignty engineering. We build proprietary infrastructure for global clients, ending the cycle of SaaS dependency. By formalizing a proven framework, we deliver infrastructure that belongs to you, costs that shrink over time, and a competitive moat that grows with every deployment.
I'm Fabian Weiss.
For years, I watched companies make the same mistake: outsource their digital core to SaaS vendors and lose control, flexibility, and millions in costs. I was IT & Operations Manager at a B2B company – managing tech stacks with 20+ tools costing €8K/month.
The result? Dashboards taking 3 seconds to load. Zapier workflows breaking weekly. API rate limits stopping our automation. Every vendor update was Russian roulette. We weren't engineers anymore – we were middleware mechanics, managing Salesforce and Zapier profits while our own performance stagnated.
2023, I made the cut: Exit. Independent consultancy. I replicated the methodology dozens of times for clients worldwide. B2B SaaS, e-commerce, fintech – always the same problem: vendor bloat kills margins. Always the same solution: ownership over rent. The results: 60-75% cost reduction, 5-10x performance.
To make this methodology globally available, I transformed the consultancy into a scalable structure. FW Delta LLC was founded in January 2026 to deliver enterprise infrastructure not just as a project, but as a standardized process for digital sovereignty.
Why SaaS stacks kill your business
Average agency, 2025: $6K–8K monthly for software. Salesforce, HubSpot, Zapier, Tableau, Intercom, Segment. 20+ tools, 40% of work time spent on integration and debugging. Engineers degraded to API integrators. Every tool promises ROI. None delivers.
The real problem: You pay for features you don't use. You wait on vendor roadmaps for features you need. Your data is fragmented across dozens of systems. Your team velocity drops because every task requires 3 API calls and 5 Zapier steps.
While vendors optimize their dependency strategy (lock-in, price increases, feature gates), your margin stagnates. This isn't efficiency. This is structural value destruction. The equation is broken.
“We weren't developing software anymore. We were debugging Zapier workflows and integrating vendor APIs. That wasn't engineering – that was middleware management. The moment I knew: this needs a complete rebuild.”
Why FW Delta exists
In 2026, data sovereignty is no longer a luxury – it's a survival question. Companies delegating their data pipelines to SaaS providers pay an "innovation tax" that increases every year. AI costs are exploding. Vendor dependency is a strategic liability. We end that cycle.
The principle is radically simple: We build production-ready systems, hand you the complete source code, and ensure you can operate everything without us. No lock-ins. No licenses. No dependencies. You own the software. You control the infrastructure.
We don't build solutions that just work. We build capitalizable assets. While SaaS fees irreversibly vanish from your balance sheet, our infrastructure strengthens your equity (IAS 38). Infrastructure that compounds value. Not costs that compound liabilities.
What we do
We replace expensive SaaS stacks with owned infrastructure. Custom analytics dashboards instead of Tableau. Event-driven automation instead of Zapier. Real-time data pipelines instead of Fivetran. Tech decisions based on your requirements – not vendor roadmaps.
Our tech decisions are based on production-grade standards and your specific requirements. Proven technologies that have been running in enterprise environments for years. Hetzner Bare Metal (ISO/IEC 27001:2022 certified) for data protection compliance. No cloud premiums. Only production-ready tech.
How we work
I'm the core – architecture, quality control, coordination. For execution, I orchestrate a vetted network of specialized engineers. No overhead. No sales teams. No corporate politics.
The era of SaaS dependency is over.
With FW Delta, I offer you the path back to technological autonomy. We combine the surgical precision of high-stakes consultancy with the scalability of a modern engineering organization.
The goal: Infrastructure you own. Costs that shrink. And a competitive advantage no one can take away from you.
This allows us to scale instantly without the bloat of traditional agencies. You get senior-level engineering at costs 60-75% below enterprise SaaS. This isn't a sales pitch. This is math.
The Anti-Agency Manifesto.
Ownership Creates Control.
Renting your core infrastructure gives vendors control over your competitive advantage. We build capitalized assets (IAS 38) that strengthen your balance sheet – not recurring expenses that weaken it.
Simplicity Compounds.
Enterprise software becomes bloatware. We practice radical reduction – delete unnecessary code, eliminate middleware, build direct connections. Performance and maintainability scale from simplicity, not complexity.
Engineering First, Upsell Never.
We're not optimizing for customer lock-in or recurring revenue. We optimize for your business outcomes. We operate with surgical precision – special forces discipline, not sales-driven committee politics.
Radical Transparency.
Radical Performance.
We don't hide behind buzzwords. We're engineers. Our "secret sauce" is high-quality code and robust architecture – not marketing fluff.
While others resell "cloud solutions" with markup, we deploy on Hetzner Bare Metal (ISO/IEC 27001:2022 certified). Why? Because we care about data sovereignty, latency, and your budget. And because owned hardware without cloud premiums often delivers more performance at lower costs.
FW Delta is the core – architecture, quality control, coordination. For execution, we work with a strictly vetted network of specialized engineers. This allows us to scale without carrying the overhead of a traditional agency.
