Deep Expertise Where Precision Matters Most
We've spent 12+ years inside industries where reliability, safety, and compliance are non-negotiable. That depth means we catch failure modes generic teams miss, and build systems that hold up under audit, not just under demo.
ITS & Smart Mobility
We build the software underneath city traffic: the signals, sensors, and systems that keep roads moving. In transportation, a system failure isn't an inconvenience, it's a safety risk.
- Traffic Management & Control Systems
- C-ITS / V2X Roadside Software
- Real-time Signal Optimization
Smart Energy & Grid
We build the software that keeps power grids stable as they evolve. Utilities can't afford downtime, so every system has to hold up under real-world load.
- Grid Modernization
- Smart Meter Platforms
- OT/IT Integration
Manufacturing & DX
We build the software behind modern factory floors. The kind that replaces gut-feel maintenance schedules with real data from the line.
- AI Vision for Quality & Safety
- Predictive Maintenance & OEE
- IIoT Sensors & Edge Gateways
Logistics Infrastructure
We build the software that keeps baggage, cargo, and equipment moving through busy hubs. A few minutes of lag can quickly turn into missed connections and hours of delay.
- Baggage Handling & Sorting Software
- Equipment Control Software
- Platform & TOS Integration
SaaS & Product Dev
We build the software behind fast-growing products. When you need to ship a feature fast, we work across the whole stack. Nothing stalls just for a handoff between teams.
- Cloud-Native & Platform Migration
- AI & Intelligent Automation
- Full-Stack Feature Engineering
Fintech & Trading
We build the software behind fast and secure financial transactions. When money is moving, there's no room for a slow system or a dropped transaction.
- Low-latency Trading Systems
- Payment & Settlement Platforms
- PCI-DSS & Regulatory Compliance

Insights & News
Modernizing Legacy Systems with the Agent-Centric Development Cycle
Legacy code is code without tests - and the safety net that fixes it was always too expensive to build. That is the cost AI agents actually attack.
RACI Chart: What It Is, How to Build One, and Where It Breaks
A RACI chart assigns Responsible, Accountable, Consulted, and Informed to every task so nobody has to guess who owns what. Only one person can be Accountable, and that single rule is what keeps the chart from turning into finger-pointing.
Custom Software Development Company: An Evaluation Guide
Rate and brand name tell you less than you would think about whether an engineering partner actually fits. Eight things to check first, from security certifications to who is really doing the work.
Frequently Asked Questions
What kind of companies does Eastgate work with?
We serve two distinct groups: global enterprises and system integrators building mission-critical infrastructure (transportation, smart mobility, industrial systems), and growth-stage product companies scaling their engineering teams.
Our clients include long-term strategic partners like Siemens Mobility and Yunex Traffic (12+ years), as well as Autobahn GmbH and funded SaaS and fintech companies across the US, EU, and APAC.
Are your engineers in-house or subcontracted?
Our 200+ engineers are in-house, not subcontracted.
For urgent timelines, we may temporarily engage vetted specialists to start immediately, then transition to permanent in-house team members. You always end up with a fully in-house team.
We are ISO 27001:2022 and ISO 9001:2015 certified and adhere to GDPR standards across all engagements.
How quickly can you ramp a dedicated team?
Typically 4-6 weeks for a productive, dedicated team.
We assemble purpose-built teams with a solution architect, tech lead, and engineers matched to your domain and tech stack, then embed them into your workflows.
What makes Eastgate different from other development partners?
Three things: domain depth, engineering culture, and retention.
We've been a strategic engineering partner to Siemens Mobility and Yunex Traffic for 12+ years, delivering mission-critical systems that meet German engineering and industrial cybersecurity standards (IEC 62443-4-1).
Our 93% client retention rate across 130+ clients in 15 countries reflects that. And with ISO 27001 and ISO 9001 certifications, we operate at enterprise-grade quality across every engagement.
Do you price on time-and-materials or outcomes?
We offer outcome-based engagement models anchored to deliverables and milestones - not hours logged.
Some clients prefer a dedicated team structure, but pricing is always tied to what ships, not how long it takes.
We'd rather deliver faster and earn the next engagement than stretch timelines to bill more.
