Data Modernization Services
Turn Legacy Infrastructure Into
AI-Ready Data Architecture
StratApps delivers end-to-end data modernization services for SaaS companies and enterprises — replacing brittle pipelines, siloed warehouses, and manual ETL with a cloud-native, analytics-first foundation built to scale.
What Are Data Modernization Services?
Data modernization is the systematic process of replacing outdated data infrastructure — legacy warehouses, on-prem servers, fragile custom ETL scripts — with cloud-native, event-driven, and AI-ready architecture. It is not a lift-and-shift migration. Done right, it re-architects how data is ingested, stored, governed, and consumed across your entire organization.
- Migrating from legacy data warehouses to cloud lakehouses
- Rebuilding fragile ETL pipelines into reliable, observable data pipelines
- Unifying siloed data sources into a governed, single source of truth
- Enabling real-time and streaming analytics at enterprise scale
- Laying the data foundation required for AI and machine learning workloads
Why Now
The Business Drivers Behind Data Modernization
Three forces are making modernization urgent for every SaaS company and enterprise in 2025 and beyond.
Runaway Infrastructure Costs
Legacy on-prem data warehouses and oversized cloud subscriptions carry hidden costs — licensing, maintenance, manual operational overhead. Modern cloud-native architectures reduce total data infrastructure spend by 30–50% through elastic compute and pay-per-query models.
Scale Without Infrastructure Ceilings
Data volumes double every two to three years. Legacy systems hit throughput walls, slow query performance, and block product team velocity. Cloud-native lakehouses and streaming pipelines scale horizontally with demand — no re-architecture required as you grow.
AI & ML Readiness
Every AI initiative — predictive analytics, LLM-powered products, anomaly detection — depends on clean, well-governed, high-frequency data. Most enterprises cannot unlock AI ROI because their data infrastructure was never designed to support it. Modernization is the prerequisite.

Built Specifically for SaaS and Data-Intensive Enterprises
SaaS companies face a distinct set of data modernization challenges: high-cardinality product event streams, multi-tenant data isolation requirements, and the pressure to move fast without breaking analytics. StratApps brings patterns proven across dozens of SaaS data modernization engagements.
- Multi-tenant data architecture with row-level security
- Event stream ingestion from product analytics tools (Segment, Amplitude, Mixpanel)
- Usage-based metrics pipelines for billing and RevOps
- Customer health data unification across CRM, support, and product
- Self-serve analytics enabling CSMs and PMs without SQL knowledge
- Data contracts and schema governance to protect downstream consumers
Our Methodology
From Legacy Systems to Production-Ready Architecture in Four Phases
Every engagement follows a structured delivery model — reducing risk, accelerating time-to-value, and building internal capability alongside modern tooling.
Phase 01
Discovery & Data Infrastructure Audit
We inventory every data source, pipeline, warehouse, and downstream consumer across your stack. Output: a technical debt map, a capability gap analysis, and a prioritized modernization roadmap aligned to your business goals — not a generic blueprint.
Phase 02
Architecture Design & Technology Selection
We design the target-state architecture — selecting cloud platforms, storage formats, orchestration tooling, and governance frameworks based on your team's skills, budget, and growth trajectory. We present trade-offs clearly so your engineers and leadership make informed decisions together.
Phase 03
Incremental Build & Migration
Migration happens in incremental, production-safe releases — not a big-bang cutover. We migrate pipeline by pipeline, validate against the legacy system, and hand off ownership to your team at each stage. No extended freeze periods, no surprise downtime.
Phase 04
Operationalize, Monitor & Optimize
We instrument every pipeline with data observability tooling (Monte Carlo, Great Expectations, or dbt tests), set up alerting, document runbooks, and run knowledge-transfer sessions with your team — so you own a well-operated data platform, not a black box built by a consultant.

FAQ
Frequently Asked Questions About Data Modernization Services
What is the difference between data modernization and cloud migration?
Cloud migration moves workloads from on-premises to cloud infrastructure — it is primarily a hosting change. Data modernization is broader: it re-architects how data is ingested, transformed, stored, governed, and consumed. Many organizations complete a cloud migration and still have the same fragile pipelines and siloed architecture — just running on cloud VMs instead of on-prem hardware. True data modernization addresses the architecture, not just the hosting environment.
How long does a typical data modernization engagement take?
Scope varies significantly by complexity. A focused pipeline modernization or data warehouse migration for a mid-size SaaS company typically spans 8–16 weeks. A full enterprise data platform re-architecture — covering multiple business units, a new lakehouse, and self-serve analytics — is more commonly a 4–9 month engagement delivered in phases. StratApps scopes engagements in fixed phases so you approve and control each stage before committing to the next.
How much do data modernization services cost?
Engagement size drives cost more than any single factor. Phase-one discovery and audit engagements are typically priced between $15,000 and $40,000. A full pipeline and warehouse modernization for a Series B or C SaaS company commonly ranges from $80,000 to $250,000, depending on data complexity, the number of source systems, and the degree of analytics layer work included. We provide fixed-fee scoping for each phase — no ambiguous time-and-materials billing.
What data platforms and tools does StratApps work with?
We are stack-agnostic and certified across the major modern data platforms: Snowflake, Databricks, Google BigQuery, and Azure Synapse for cloud warehousing and lakehouses; dbt, Apache Spark, and Airbyte for transformation and ingestion; Airflow and Prefect for orchestration; and Looker, Tableau, and Metabase for the analytics and BI layer. We select tooling based on your team's skills and your architectural requirements — not on vendor preference.
Does StratApps offer data modernization consulting specifically for SaaS companies?
Yes — SaaS data infrastructure is a core specialization. SaaS companies face distinct challenges: multi-tenant data isolation, high-cardinality product event streams, usage-based billing pipelines, and the need to unify CRM, product analytics, and support data for customer success and RevOps use cases. Our team has designed data architectures for dozens of SaaS companies at Series A through post-IPO stages.
Will my existing team be able to operate the new infrastructure after the engagement?
Ownership transfer is a deliverable in every StratApps engagement, not an afterthought. We document every pipeline, write operational runbooks, instrument observability tooling, and run hands-on knowledge-transfer sessions with your data engineering team. Ongoing managed support is also available through our Data as a Service offering if you prefer a fully managed model.
What is the first step to getting started with a data modernization project?
The best starting point is a free 60-minute data infrastructure assessment with one of our senior data engineers. We review your current architecture, understand your growth goals, and identify the highest-priority modernization opportunities — with no obligation. From there, we can scope a Phase 1 discovery engagement or jump directly into a focused pilot if you have a specific bottleneck to address first.
