B2B SaaS Copywriter for Growing Companies

You've won over the early adopters, but pragmatists are a different kettle of fish. Taking your SaaS to the next level is about being the trustworthy, reliable, and credible option for your ICP.

You're not the scrappy underdog anymore

When you're first starting out, your marketing is about challenging the status quo. It's about romancing those early adopters with something new and shiny. But that doesn't work forever. Now you need to win over the risk-averse, and that's not easy.

Your new ICP isn't after new and shiny. They want to be confident that their buying decision doesn't come back and bite them on the arse. They don't care about your rank on Product Hunt, your hype on Reddit, or how much you've raised. They want to see signals that make them feel safe.

This is the credibility gap.

Diagram showing the credibility gap for B2B SaaS

Seven years of SaaS copy taught me one thing.

The Credibility Multiplier

Brands with strong credibility signals find that everything works better. Copy lands harder. Prospects come into conversations already half-convinced. The formula is simple: Buying likelihood = (Price + Positioning + Product) × Credibility. The maths is the point. Credibility doesn't add to your other efforts; it multiplies them. My job is to raise that number.
  • Copy that builds trust
  • Content that demonstrates authority
  • A narrative that compounds over time

Alessandro Trezza, Co-Founder at Creatora
"Jon helped us see things from a sharper, more strategic perspective. In just two days, we completely rewrote Creatora's homepage. Same product, same features, but a radically clearer story. He didn't just improve our messaging. He saved us weeks of wandering in the dark."

What I actually do

The services I provide to growth-stage SaaS companies.

Messaging & Copy

I work on the messaging layer first: who you're for, what you actually do differently, and why that matters. Then I write copy that carries that message without losing it in the second paragraph.

Content Strategy & Writing

I build content strategies around your positioning, then write the pieces that make people think 'these people actually know what they're talking about.'

Credibility Audit

I'll work through all five categories of credibility signal and give you a clear picture of where you're losing prospects before you've had a chance to pitch them.

Stuart Broad, Founder at SaaSy DB
"I'm not a great copywriter, and I'm certainly not a positioning expert. Jon is both. His feedback on how to improve the positioning of my SaaS company was powerful, but also easy to digest and easy to implement. I'd recommend Jon to anyone whose marketing website is important to their company's growth."

Seven years. A lot of SaaS. One framework.

I've been writing copy and content for B2B SaaS companies since 2018. Startups trying to explain what they do for the first time. Established players like WorkNest, Elastic, and Float who needed a sharper story. The Credibility Multiplier came out of that work.

What's your credibility score?

Most SaaS companies have no idea where their credibility is leaking. The Credibility Scorecard takes three minutes. It scores you across all five credibility signal categories and tells you exactly where the gap is and what to fix first.

Bad Positioning Kills Good SaaS

Bad Positioning Kills Good SaaS

Most SaaS companies think their marketing isn't working because the copy's bad, the ads aren't targeting right, or the budget's too small. It's usually none of those things. It's that nobody really understands what the product does or who it's for. This book is about fixing that: how to position your SaaS so clearly that prospects stop comparing you with the competition, and AI stops lumping you in with it too.

The First Domino

Most SaaS companies produce a lot of content and get very little out of it. The reason is usually that they're creating the wrong piece first. There's a specific type of content that builds credibility, earns trust, and makes every other piece of marketing work harder. This book is about finding that piece and getting it right.
