Every B2B SaaS company that acts as a system of record - CRMs, property management platforms, clinical practice systems, field service tools - has the same onboarding bottleneck. The customer signs. Then someone has to get thousands (sometimes millions) of rows of messy data out of the old system and into the new one.

This usually goes one of two ways. Either you hand the customer a CSV template and they spend days reformatting their data to match it. Or your dev team writes a custom ETL script (or duct tapes an iPaaS), which takes even longer when you count the back-and-forth.

For a 170k row dataset with 10 tables, CSV imports take about 43 hours of total effort. Custom scripts take about 20. Vern does it in under one.

Vern is an AI-powered migration tool purpose-built for this problem. You configure it once for your platform's data model and import templates. Then every new customer gets a migration experience that works like this:

1. Upload

The customer drops in their raw exports. CSVs, Excel files, PDFs. No reformatting. No templates. Vern takes it as-is.

2. Explain

Vern reads the data and asks targeted questions. Not a generic checklist — questions generated from what's actually in the files. Each question shows the relevant source data alongside it so the customer can answer with confidence.

3. Approve

Vern produces a plain-language summary of every transformation: how entities will be organized, what gets cleaned, what the output looks like. The customer reviews, approves, and the import runs. 1M+ mappings, transforms, calculations, all run in a click.

Why this matters

The migration step is usually the longest gap between "contract signed" and "customer sees their data in the product." It's where onboarding stalls, where churn risk spikes, and where your team burns the most hours on the least leveraged work.

It also caps your deal size. The biggest customers bring the biggest datasets. If every migration requires custom engineering, you can only onboard as fast as your team can write scripts.

Vern removes that constraint. Same workflow for 100 rows or 1,000,000.

If your onboarding team is spending more time wrangling data than building relationships, we should talk.
