Behind the Numbers: How 5 FinServ Data Teams Modernized Their Data Stacks

In financial services, modernization advice rarely comes with the receipts. The vendor pitch deck skips the part where the POC almost broke. The consultant's case study redacts the stack choices. The conference panelist won't say what they'd do differently.

This guide fills the gap. Five teams - at Group 1001, HUB International, United Community Bank, Security Benefit, and Q2 - walked through the moves they made, the numbers they measured, and the details they wish they'd known going in. The pattern across all five is remarkably consistent.

Inside the guide, you'll discover:

• A team of 5 replacing 3-month cycles with 2-day sprints: How Group 1001's annuities data team migrated 4 TB, replicated 66 databases, and hit 10x productivity in under a year.

• 80-hour Excel reports replaced with near-real-time analytics: How HUB International's clinical informatics team built an entire warehouse plus four data marts in under 100 hours, saving ~$54K in dev time.

• Built-in governance from day one - and developers building on weekends for fun: How United Community Bank parsed complex JSON 75% faster, loaded Parquet 4x faster, and got adoption before asking for it.

• A deliberately brutal POC and a foundation for AI: How Security Benefit cut a key migration step from two months to two weeks and collapsed experimentation cycles from 1+ week to 15-20 minutes.

• 60% runtime reduction and immediately lower Snowflake spend: How Q2 migrated ~400 objects in just over two months and stopped paying for a warehouse that ran 24 hours a day.
