The Silent Killer of Fintech Startups
I’ve been in fintech for a while—eight years in the markets, worked for multiple fintech companies, and used hundreds of tools as both a trader and a builder.
And if there’s one thing that gets consistently overlooked but makes or breaks the user experience?
Documentation.
Not sexy. Not a “next big thing.” But absolutely vital.
Why It Matters
Good documentation drives signups, reduces churn, and makes users happy.
Bad documentation?
It does the opposite:
- Customers sign up expecting one thing and get something else.
- They get confused, pissed off, and bail.
- Support queues fill up with basic questions that shouldn't need to be asked.
- Internal teams don’t even know how the product works—so they can’t explain it clearly, either.
It’s a mess.
Here’s the Reality
Most fintech companies don’t have bad docs because they’re lazy.
They have bad docs because they’re building too fast, shipping half-baked features, and forgetting to slow down and clarify what the hell they actually offer.
So what happens?
- No one on the team fully understands the product.
- Product changes, but the docs don’t.
- Support gets overloaded.
- Users leave before they even get going.
And the cycle repeats.
Who’s Doing It Right?
A few stand out:
- Finviz — Clear, simple, and comprehensive documentation—especially around Finviz Elite.
- StockAnalysis — Extremely intuitive platform with no guesswork needed.
But the vast majority?
Cluttered, outdated, or just plain missing.
The Fix Is Simple (But Rare)
Before you chase the next “big idea,”
document what you’ve already built.
Clarify how your product works.
Create fewer support tickets.
Make your users feel confident.
And stop burning so much on churn.
It’s not a feature.
It’s not a redesign.
It’s just writing things down clearly—and it might be the single highest-leverage move your fintech company can make.
Done right, your documentation becomes your best salesperson and your best retention tool.
Ignore it, and you’ll keep watching your users quietly (and many not so quietly) disappear.
