Why Good SaaS Fails (And Mediocre SaaS Thrives)

At the end of 2025 I had a bit of an epiphany. After several years as a copywriter, I was trying to work out why some companies excel with terrible copy, while some flounder with excellent copy.

And when I talked to industry colleagues about this, they noticed the same thing about SEO, branding, ads, etc. They could use the same tactics, tools, and techniques and get wildly different results depending on the brand. Especially when it came to conversion.

I researched this more, looking at brands that did well vs brands that struggled, and noticed one key factor: Credibility.

Brands that have clear credibility signals find it much easier to get traction with whatever marketing they’re doing:

• Their copy is more convincing
• Their ads carry more weight
• Prospects are more open to what they say

At first I tried to envision this as a sort of credibility filter. That how a prospect looks at a brand is filtered through how credible they already think they are. But this was flawed because credibility doesn’t always come before the offer. Sometimes you learn of a brand, product, or service and then look for those credibility signals.

You might see an ad, so you go to the website to see if it seems legit. Or you might Google them. Or look for reviews.

So instead of being a filter, I realised that credibility is a multiplier.

The Credibility Multiplier

This is what the credibility multiplier looks like:

Buying Likelihood = (Price + Positioning + Product) × Credibility

It doesn’t matter where in the process the credibility comes in. What matters is that those credibility signals multiply the efficacy of everything else.

The reason this happens is simple: Trust.

If two friends ask to borrow £50, and you can only afford to lend one of them the money, you lend the money to the friend you trust the most.

This is the same with sales and marketing. Especially at the B2B level where you’re often investing a large amount of money in the solution you choose. Even if one has better price, product, and positioning, it’s too risky if they don’t seem credible.

Credibility is why Microsoft Windows is still the most used operating system despite its poor product, uninspiring marketing, and relatively high price.

It’s also why you could invent the best software in the world, with great positioning and a low price, and you’ll still struggle to find new customers.

Credibility Signals

Every industry has different credibility signals, but for this article I’ll focus on those that apply to B2B SaaS (because that’s the industry I know best).

While I was researching and fleshing out my credibility thesis, I found that most credibility signals fall into one of five categories: Social Proof, Authority, Brand Presence, People, and Process. There is inevitably a bit of crossover here and there, but it makes it easier to evaluate a company’s credibility by focusing on these five areas.

1. Social Proof

One of the fastest ways to demonstrate your credibility is by letting your existing customers do the talking for you. Nothing reassures a prospect more than reading, hearing, or (ideally) watching an existing customer rave about how much you helped them.

Examples:

• Case studies
• Testimonials
• Reviews
• User statistics
• Customer logos
• Product Hunt awards/achievements

2. Authority

Authority is all about a different type of trust. This is more about making prospects trust that you know what you’re doing. This comes from teaching, showing up as an expert, and proving you know your stuff. For a SaaS, this could either be your founder, another face of the company, or a broader educational effort.

Examples:

• Awards
• Educational content
• Podcasts
• Webinars
• Newsletter

3. Brand Presence

There’s validity to the advice “Dress for the job you want, not the job you have”, and it translates to your brand presence, too. If you have a thrown-together website, or a logo that’s clearly just a Canva template, it screams “temporary”. Which can be fine, but it doesn’t help your credibility. Having an appropriate, professional brand presence tells prospects you’re a proper company that will still be here in two years. Professional headshots of the team, a cohesive social media presence, etc. all have an impact here.

Examples:

• Website design
• Website experience
• Social media
• Consistent branding

4. People

Especially if you’re a smaller SaaS, how you present the people in your company can make a big difference. Sometimes all you need is a strong founder brand, but sometimes it’s about showing off the experience of your team. If you’ve got a dev team with a combined 50 years of experience, make that clear. This is especially important when you’re competing with developers who only started coding ten minutes ago.

Examples:

• Founder brand
• Team size
• Employee activity
• Staff branding

5. Process

The final piece of the credibility puzzle is being transparent about how you do business. Don’t hide your pricing behind a phone call, don’t be coy explaining how features work. Instead, be an open book. Tell your prospects how much your software costs, what the onboarding process is, and how they can get help when they need it. These days, your prospects are comparing you with ten other options. Don’t disqualify yourself by coming across as secretive or opaque.

Examples:

• Pricing clarity
• Onboarding process
• Reliability and support
• Policies and compliance

The Credibility Scorecard

As part of this process, I created a scorecard to make it easier to evaluate a company’s current perceived credibility. It runs through key indicators that will make the biggest difference.

The scorecard walks you through targeted questions based on these five credibility categories. At the end you get a score and actionable advice on where to focus your credibility-building efforts.

If you’re trying to figure out why your product isn’t converting as well as it should, run through this framework. Odds are the issue isn’t your product—it’s the credibility signals prospects are seeing (or not seeing).
