Stop building Frankenstein products

Startups are known for being hacked together. You take feedback, ship fast, and solve real problems. But somewhere along the way, many founders fall into a dangerous trap: building Frankenstein products.

These are the platforms, apps, and tools cobbled together from customer requests, stakeholder demands, and rushed feature releases.

At first glance, they look impressive. Lots of functionality, lots of tabs, lots of... stuff. But open the hood, and it’s chaos: disjointed user experiences, redundant features, tech debt piling high, and a product team struggling to remember why half the buttons exist.

We’ve seen too many early-stage startups lose time, customers, and clarity by overbuilding before truly understanding their product’s core value. This article is your intervention.

Let’s talk about why Frankenstein products happen, how they hurt your business, and what you can do instead to build leaner, cleaner products.

What is a Frankenstein product?

A Frankenstein product is one that’s been built reactively rather than strategically.

It’s the result of stitching together too many features without a clear vision. These features often come from:

• A big client who said “we’ll sign if you build this one thing”
• Internal teams lobbying for their preferred tools
• Customer feedback that’s taken too literally
• Panic-driven roadmaps that favour speed over simplicity

Think of a CRM that tries to be a sales tool, a project management platform, a marketing suite, and a data warehouse – all at once.

Or a healthtech app that started as a simple symptom tracker and somehow morphed into a full telehealth solution, complete with messaging, billing, wearable integrations, and six onboarding flows.

Frankenstein products try to be everything to everyone. In doing so, they often end up being loved by no one.

Why it happens in startups

Startups are under pressure. Investors want traction. Customers want customisation. Competitors launch new features. There’s a natural urge to build fast and say yes.

But saying yes too often, without revisiting your product’s core reason for being, is how things unravel. Here are a few common causes:

1. Customer whiplash

You want to be customer-led. So when one user asks for a filter, you build it. When another says your dashboard’s missing something, you add it.

Over time, your product becomes a patchwork of one-off requests, none of which are validated at scale.

2. The big client temptation

A potential customer waves a big cheque, if only you’d add this one feature. You scramble to build it, even though it doesn’t align with your long-term roadmap.

You close the deal, but now your team is stuck maintaining a function no one else wants.

3. No clear product owner

Without a strong product lead (or founder playing that role), decisions get made by committee. Sales wants one thing, marketing another, and engineering tries to please both. The product becomes directionless.

4. Fear of saying no

Startups often fear that saying no will lead to churn. But trying to keep every user happy is a fast track to bloated UX, rising support tickets, and technical complexity.

The hidden costs of Frankenstein products

Frankenstein products don’t just feel clunky. They slow down your business in ways that are easy to miss.

Here are some of the warning signs and the symptoms of Frankenstein products:

• Slower development cycles: Every new feature becomes harder to build because of legacy code and tangled dependencies.

• Higher churn: Users don’t stick around when your product is confusing or overwhelming.

• Inconsistent brand experience: Your product starts to feel messy, like a series of disconnected modules, not a cohesive solution.

• Team burnout: Product, engineering, and support teams end up maintaining things they don’t believe in or understand.

Worst of all, you lose sight of what made your product great to begin with.

What your startup should do instead

Escaping the Frankenstein trap doesn’t mean ignoring customers or freezing development. It means building with discipline.

Here’s how to refocus your approach.

1. Define the heart of your product

Every great product has a core – the essential thing it helps users do. In medicine, it might be tracking treatment plans.

In logistics, it might be optimising delivery routes. Identify your product’s heart then ask: does this feature strengthen the spine or distract from it?

If it’s not essential, it’s negotiable. And it’s usually worth leaving on the cutting room floor.

2. Say no (nicely)

You don’t need to build every request. Instead, thank your users, log the idea, and evaluate it in context of your broader roadmap.

Be transparent: “That’s not something we’re prioritising right now, but we’ll revisit it once we finish simplifying our analytics experience.”

Clarity builds trust, and so does focus. So use them when you need to.

3. Validate before you build

Before writing a line of code, pressure-test ideas through mockups, interviews, and experiments. Will this feature move the needle for at least 20% of users?

If not, it may not be worth the cost of the build.

4. Prune away ruthlessly

Every few months, run a “product garden” audit. What can be trimmed? Which features are being used? What’s causing confusion?

You don’t need to be precious, cleaning up is just as important as building new things.

5. Keep a “not yet” list

Instead of saying yes or no in the moment, keep a list of “Not Yet” ideas. Review them quarterly. Often, the urgency fades, or the solution becomes clearer with time.

This lets you stay responsive without being reactive, and stops you spending time where it is not helpful.

6. Invest in product design

Design isn’t just aesthetics. A good designer helps shape how users navigate your product, what matters most, and where the friction lies.

A Frankenstein product usually has poor design discipline: screens added as afterthoughts, clashing layouts, duplicated workflows. Don’t let that be you.

Final thoughts

A clear, well-scoped product is a growth machine. It’s easier to sell, easier to support, and far more loved by users. Simplicity is a competitive edge.

At Stone & Chalk, we work with founders every day to help them distil, validate, and scale their ideas without getting distracted by the noise.

Whether you're building AI, fintech, medtech, or anything in between, the principle holds: Do less. Do it well. Make it matter.

So if you’re feeling overwhelmed by your roadmap, or if your product feels more like a Frankenstein monster than a finished sculpture, it’s time to pause, reset, and start pruning. That, and only that, will help chain the monster.
