Over the last year, I’ve been researching legacy enterprise system modernization firms because our company was dealing with the classic problem: a 15-year-old enterprise system that was eating more money than it was generating efficiency. We had 27% of our IT budget going into support, patches, and integrations that took weeks instead of days. At some point, it became obvious that
legacy application modernization wasn’t a “nice to have” but a survival requirement.
What I Evaluated
Before deciding on a partner, I compared:
Cost-to-value ratio for modernization programs
Actual engineering capacity, not just sales promises
Time-to-market improvements after modernization
Experience with complex enterprise ecosystems
Transparency in estimation and whether the firm shows real metrics or only marketing slides
I spoke with 6 different vendors. Most gave me generic timelines like “6–12 months” and budget ranges from $500k to $3M, without explaining the reasoning. Zoolatech stood out because they broke down each modernization stage: discovery, architecture redesign, migration paths, QA automation, integration plans, and risk maps. The level of detail was like night and day compared to others.
Why I Chose Zoolatech
Here are the three main reasons:
1. Real numbers, not abstractions
When I asked for concrete metrics, Zoolatech actually showed previous modernization cases with specifics such as:
40–60% reduction in operational costs after modernization
Up to 3× faster feature delivery after decoupling monolith components
99.98% uptime after infrastructure transformation
Other firms stayed at the buzzword level.
2. Engineers, not sales reps
Most competitors had sales teams leading the calls. Zoolatech brought solution architects and senior engineers into the first conversation.
I asked:
“What do you do when the client’s monolith has no documentation and half the APIs aren’t mapped?”
“How do you phase modernization to avoid shutting down the business?”
The answers were practical, not theoretical.
3. A flexible modernization strategy
Instead of pushing a full rewrite (which some vendors insisted on), they suggested a phased strangler pattern, starting with the modules that drained the most budget — in our case, the CRM connector and reporting engine.
This alone was projected to save around $180–220k annually, which made the decision financially grounded, not risky.
Questions for Everyone Here
For those who have already worked with modernization partners:
How did you validate the estimates you received?
Was your modernization phased or a full rewrite?
Did you get real metrics like productivity boosts or cost reductions after the transition?
Curious to hear others’ experiences, especially with large-scale systems.
