SOFTWARE DEVELOPMENT AGENCY | 91
Software Development for Complex Operational Systems.
| 91 is a software development company focused on scalable systems architecture, integrations, automation and intelligent operational infrastructure.
Start the conversationSoftware rarely fails in code.
It fails in systems.
Most organisations already have the tools they need. What they lack is structure.
Systems evolve without design. Tools are added without integration. Workflows depend on manual intervention.
Over time, complexity becomes the constraint.
We design systems that resolve that complexity.
We:
✓ Connect fragmented platforms into one system
✓ Structure data so it flows across operations
✓ Remove manual processes that slow teams down
✓ Embed automation where it creates leverage
The result:
Systems that operate as a unified architecture — not a collection of tools.
From system design to execution — end to end.
We don’t separate thinking from building.
✓ System architecture is defined and implemented by the same team
✓ Decisions made during design carry through to execution
✓ No handovers between strategy and development
Critical systems require continuity.
Systems thinking first. Technology second.
We don’t start with tools or frameworks.
We start with how your organisation operates. How data moves across systems. Where decisions are made. Where dependencies exist. Where complexity is introduced. Where automation creates leverage.
From there, we define the system architecture. Technology follows.
We operate across three areas.
Built over time.
Built over time. Designed to stay focused.
| 91 was founded in 2010 in the Netherlands by Daan Mallens and Ritesh Ksheersagar. The focus has remained consistent:
designing systems that resolve operational complexity.
Founder-led.
System-driven.
We stay directly involved in:
system architecture
technical direction
critical design decisions
This ensures continuity from design to execution.
Still the startup.
By design.
No layers. No handovers. No separation between design and execution. We keep the team small so:
decisions stay sharp
systems stay coherent
complexity doesn’t increase internally
We work where systems matter.
SaaS platforms.
Systems that need to scale across users, data, and integrations.
FinTech companies.
Legacy systems, compliance workflows, and operational complexity.
E-commerce infrastructure.
Multi-channel operations, fragmented tools, and scaling challenges.
Enterprise environments.
Large system landscapes that must operate as one.
We don’t deliver features.
We design systems.
Clients work with us when: systems become a constraint, operations don’t scale, complexity starts slowing the business down.
We design systems that: hold under pressure, integrate across platforms and improve as complexity increases.
Real systems. Real impact.
What we’re seeing.
If your systems need to scale — we should talk.
If you’re looking for a development team, we’re not the right fit. If you need systems your business can depend on — we are.
