Among the 22 companies that participated in this research

Why this research exists?

Most SaaS teams building editing functionality make the same decisions in the same low-information way: by familiarity, by what the last company used, or by what a developer happened to know.

The library chosen in 2019 produces its migration cost in 2024. The collaboration feature built without user research becomes a baseline expectation nobody pays a premium for. The AI investment made for the wrong stage generates demos, not metrics.

The gap between companies that use their editor strategically and those that manage it reactively isn't a capability gap. It's a decision gap.

"The decisions are more consequential, more technically complex, and more expensive to reverse than they appear at the moment they are made."

Flexum Research, 2026

We interviewed 22 SaaS leaders: CTOs, VPs of Product, founders, engineers. We asked what they built, why, what surprised them, and what they would do differently.

What's inside

Three parts. Eight chapters. Every one grounded in real conversations with real teams.

01

The Business Case

1

What "Advanced Editing" Actually Means

Six distinct forms of in-app editing, and why confusing them is the first mistake.

2

How Editing Investment Connects to Revenue

Three mechanisms that link editor quality to sales velocity, retention, and pricing power.

3

When Editing Does NOT Drive Revenue

The patterns that make heavy editor investment a waste, and how to recognize them early.

02

The Decisions That Define Your Editor

4

Build vs. Buy: A Decision Few Teams Make Deliberately

The framework for getting this right the first time, and what it costs to get it wrong.

5

The Library Landscape

Configurable vs. composable architectures, and why teams keep migrating in the same direction.

6

Migration: The Cost Nobody Budgeted For

Three live case studies. The hidden costs that surprised every team that went through it.

7

Real-Time Collaboration: Not One Problem, Four

Why "we need collaboration" is the wrong question, and what the right one reveals.

03

What's Changing

8

AI in the Editor: The Right Questions, Asked Too Rarely

What's actually moving metrics, what's just keeping up with the trend, and the data ownership angle nobody is pricing in.

"The need is ubiquitous, the specialists exist, and the teams who need them have no idea they're there."

From the research

"In retrospect, I would have engaged a specialist rather than building from scratch. The project took longer than planned and cost more than we budgeted."

Roland Pokornyik

Co-founder, Chamaileon

"So many apps have this need for content editing. If you don't know how it works, you're going to have a pretty hard time."

Daniel McFarland

Head of Design & UX, Quire

"If it's central to how your product differentiates, you don't want to leave that to a third party."

Tacita Morway

Fractional CTO

Who this is for

If your product lives or dies by its editor, this is for you.

Choosing a foundation

You're picking an editor library, or realizing the one you have won't scale.

The wrong choice compounds silently for years. This research maps the landscape so you can decide deliberately.

Managing a migration

You're on CKEditor 4, TinyMCE, or something that made sense in 2018.

Three live migrations: the hidden costs, the timeline surprises, and what teams wish they'd done before starting.

Building collab or AI features

You're building collaboration or AI features and want to avoid the mistakes teams made before you.

There are four distinct sub-problems inside "real-time collaboration." And most AI editor investments are producing demos, not habits.

About the research

This research was produced by Flexum, a design-led engineering agency that specializes in editor stacks for SaaS products.

We work exclusively in this space. That's what put us in a position to have these conversations, recognize what mattered, and synthesize it honestly.

The interviews were conducted between August 2025 and January 2026. Twenty-two participants. The wrong turns and the retrospective regrets are in there alongside what worked.
