Time-to-Production Calculator: In-House vs. WealthSynth

Published May 10, 2026

The hidden cost of in-house corpus build isn't dollars — it's weeks. Your team can't ship the product feature until the test corpus exists. This calculator estimates the time-to-production gap and the calendar time the firm gets back from buying.

What you walk away with

~40s · 5 inputs
  • Weeks-to-production-ready corpus for in-house build vs. WealthSynth.
  • Calendar time saved (the answer to 'when can we ship?').

FAQ

Why does vertical depth matter so much?

Because most in-house corpus builds restart 1-2 times when the team learns that an edge case they didn't model (e.g. NUA, ITIN-filer KYC) is structurally important. Deep teams catch these in design; learning teams catch them in QA or production.

Is the 6-week baseline realistic?

Roughly. A small, focused corpus (50-100 archetypes, single regulator, single product line) can be built in 6 weeks by a deep team. Anything larger or more ambitious takes the multipliers above.
