Platform modernization · Typical solution

The platform that got you here is blocking where you need to go.

40% of IT budgets go to maintaining legacy systems. Engineers who built the platform are gone. New AI features don't work because the data model was never designed for them. We modernize incrementally — the business keeps running.

Where modernization stalls

Legacy systems fail in predictable ways.

Most platforms don't collapse — they slow down incrementally until the cost of adding a feature exceeds the value of the feature.

Every new feature requires workarounds in a codebase not designed for them

The original architecture made sense in year one. By year four, product requirements have changed, the team has changed, and the codebase has accumulated enough workarounds that engineers spend more time navigating them than writing new functionality. Velocity drops — not because the team is slower, but because the architecture is.

AI features can't be built on top of legacy data models

Modern AI and ML systems require clean, consistent, structured data with reliable event history. Legacy systems have inconsistent schemas, missing audit trails, and no event log. The data foundation has to be rebuilt before AI integration is viable — and that foundational work is almost always undiscoped when the AI feature is first proposed.

AI features stall because the data foundation was never designed for them

Fragile monoliths, missing APIs, and tightly coupled modules make AI integration slow, expensive, and unreliable. Companies attempting AI features on legacy data infrastructure consistently underestimate the foundational work required before a model can be trained or deployed. The AI project stalls; the root cause is the platform underneath it.

Compliance requirements that can't be met without architectural changes

GDPR, DORA, HIPAA, and PCI-DSS requirements that were manageable at Series A become blockers at Series B and at enterprise sales. Retrofitting compliance onto a legacy architecture is significantly more expensive than designing for it — but the regulator or enterprise procurement team does not care when the requirement was added.

40% of engineering time goes to maintenance, not features

Technical debt accumulates until it consumes more engineering time than new development. Teams that should be shipping features spend their sprints on incident response, regression debugging, and architectural workarounds. The cost is invisible on a sprint board and obvious on a roadmap.

The original team is gone and nobody knows how it works

The engineers who designed the platform left. The codebase has no documentation. Tests are sparse. The rationale behind key architectural decisions exists only in Slack threads. New engineers inherit the risk without the context, and every change becomes a bet on what they don't know.

Proof of work

What comparable engagements delivered.

FinTech - Series BPlatform Modernization
Batch-to-event-driven migration: delivered in 8 months, audit trail coverage 100%, real-time risk scoring unblocked

A payments processing platform was running a nightly batch pipeline that produced compliance reports 18–24 hours after the transactions they described. This prevented real-time fraud detection and blocked the AI-based risk scoring the business needed for a new enterprise product line. We migrated the core processing layer to event-driven architecture incrementally — no downtime, live traffic throughout. The audit trail became a first-class output of the system rather than a retroactive reconstruction. Real-time risk scoring was unblocked within the same engagement.

Client feedback

What clients say about working with us.

We brought Insoftex in after our second failed attempt at productionising the model. In six weeks they rebuilt the inference layer, instrumented it properly, and gave us an eval harness our own team could extend. They told us no twice during the engagement — both times they were right.

We're very happy with the outcome and already looking ahead to the next phase. What stood out most was Insoftex's strong sense of ownership, transparent and fast communication, and ability to think beyond the initial scope to continuously add value. From day one, they supported us in shaping the product vision, through to delivering a high-quality MVP. The result is a robust platform that enables customers to easily book advertising placements and effectively drive visibility and sales. A reliable and forward-thinking partner.

We had a great experience working with the Insoftex team. They played an important role in delivering a modern application for power quality and energy generation analytics, owning both front-end development and automated QA. They built a flexible, user-centric dashboard with configurable widgets, making it easy to analyze data across devices, parameters, and time ranges. Insoftex combines strong technical expertise with a clear focus on quality and delivery. A reliable partner I'd confidently recommend.

Working with Insoftex on the social engagement platform, The Club of Names, was both productive and inspiring. They were involved far beyond development — they helped shape the product's concept and actively contributed ideas that strengthened its core functionality. Together, we built a platform that provides information about names, generates personalized articles, helps users select baby names, and includes a social feature — a chat for people with the same name to connect.
