How to explain what your SaaS does (so visitors actually understand)

If you've ever stared at your own homepage knowing it should be working — and it isn't — the odds are it isn't broken. It's that the people who'd love your product can't tell, from the words in front of them, that's what they're looking at.

This is structurally hard. You cannot un-know your own product. You read your homepage already knowing what it does, so it reads fine to you. Your visitor doesn't have that context. The gap between the two is the curse of knowledge — and no amount of staring at your own copy closes it. You are the one person who can't run the test.

The good news: there's a method. We read more than 50,000 founder and builder posts across Reddit (13,242) and Hacker News Ask (36,886) — across r/SaaS, r/startups, r/Entrepreneur, r/marketing, r/indiehackers, and Ask HN — and the same four-step pattern surfaces in every founder who eventually broke through. Apply them in order.

You're not alone — the pattern at scale

Filtering 50,000+ posts to Klarion's space via semantic search across paraphrases of each topic (v2 cosine similarity at threshold 0.40), the clarity problem is one of the largest recurring themes:

281 active-search Reddit posts match variations of "nobody understands what my product does" (4 phrasings, v2 cosine ≥ 0.40). Confusion is the single most-named diagnosis founders use about themselves.

Klarion corpus aggregation across r/SaaS, r/startups, r/Entrepreneur, r/marketing, r/indiehackers (intent_class=active_search).

825 Reddit posts wrestle with messaging and value proposition — how to say what the thing is. The strongest single phrasing ("I struggle with my value proposition") alone returns 500 posts.

  • 355 Reddit posts are about landing-page and homepage copy specifically — the first place founders go when they realize something's wrong.

The pattern spans 10+ years: top-matching posts range from 2016 through 2026. This isn't a current-cycle complaint. It's the founder problem.

Step 1 — Pass the stranger test

Before any rewriting, find out how broken the current copy actually is. Ask three people who've never seen your product to read the first screen of your homepage and answer three questions, in this order:

1. What does this product do? 2. Who is it for? 3. Why would I use it instead of [the obvious alternative]?

Don't help. Don't explain afterward. Just listen. If you get three different answers to any of the three questions — or worse, vague answers like "I think it's some kind of analytics tool?" — the copy isn't doing its job. This is the same diagnostic that surfaces in the corpus over and over, expressed most painfully by an r/SaaS founder of a 6-year-old, multi-vertical software company:

"Solid product. Thousands of users. Years of hard work. And... I still don't know how to describe what we do in one sentence."

Real revenue. Real users. Still can't explain it. The reason positioning matters isn't that it gets you to product-market fit — it's that it gets you to articulation-fit, which determines whether the product can grow beyond the people you can pitch in person.

Step 2 — Lead with the buyer's problem, not your feature

The most common failure mode in the corpus is founders who write copy about the product (what it does, how it works, how it's built) instead of about the visitor (the problem they showed up with, why it's urgent, what changes after they solve it). One founder, after months of stalled growth, posted the realization that gets the most echoes in the corpus:

"I was obsessing about adding new features to my product when I realized it doesn't matter how many features I add if people aren't going to show up. The message hasn't changed, and if it's not resonating, a new feature isn't going to make any difference."

The 45 replies were all variations of "same."

The fix: rewrite the first screen so the headline names a problem your specific buyer has, not a capability your product has. The capability appears in the next paragraph as the proof you can solve it — not as the lead. A visitor who recognizes their own problem in your first line will read the second. A visitor who reads "AI-powered platform for X" will close the tab.

Step 3 — Use the words your customers already use

Founders default to the language they've learned from building the product — technical terms, internal shorthand, category jargon. Customers don't. They describe their problem in plain, often unflattering language ("I waste two hours a week on…", "my team keeps missing…", "the current tool is impossible to…").

Pull the actual language from somewhere real: support tickets, sales-call transcripts, churn-survey responses, the Reddit thread where someone described a problem your product solves. The closer your headline's vocabulary matches what the buyer types into Google or says out loud at work, the more often a visitor reads your page and thinks "yes — this is the thing I was looking for."

Step 4 — Put proof in the first screen, not below the fold

Founders often save the proof — logos, testimonials, before/after numbers, the case study — for the middle of the page. The visitor who needs that proof to decide whether to keep reading is already gone. The first screen needs to do three things at once: name the problem, claim the outcome, and show one piece of credibility. One number, one quote, one logo bar — pick the one with the highest signal-to-noise for your buyer and put it where they actually look.

This is also how you avoid the second-most-common trap in the corpus: the 60-point checklist.

"Most articles about landing pages have 60-point checklists. 60, seriously? They're supposed to help but they only create more confusion and anxiety."

The instinct — add more, explain more, list every feature — is the same instinct that caused the problem. Clarity isn't completeness.

The case for why this matters more than features

The strongest counterargument to "messaging beats features" would be a founder describing how a single feature changed everything. The corpus has the opposite story:

"Built and launched 11 new features over three months. Usage data shows only two got meaningful adoption. Everything else is sitting at under 5% of active users. I went back and looked at session recordings for one feature I was convinced would be huge. People were clicking into it, looking around for 20 seconds, and leaving. The feature worked fine. I just never explained it properly. Most of these features aren't bad — they're just invisible because nobody understands them."

A founder who did ship — and discovered, through their own session-recording data, that shipping was half the job. 9 of 11 features failed not because they were bad, but because they were never positioned. Even the feature-driven-growth posts in the corpus mostly tell this same story: shipping without explaining is shipping invisibly.

How to know it's working

Once you've worked through the four steps, run the stranger test again with three new people. The bar isn't "they get it perfectly." The bar is consistency: three strangers describe your product in roughly the same words, and those words name the buyer's problem and the outcome — not your tech stack. If you hit that, the message is doing its job. If you don't, go back to Step 2 — the problem you named isn't sharp enough yet.

The most-upvoted version of this lesson in the corpus is a founder looking back over years of work:

"Validate the idea first. I wasted at least 5 years building stuff nobody needed."

"Stuff nobody needed" almost always turns out to mean "stuff nobody understood the need for." The two are indistinguishable from the founder's chair — and that is exactly the trap. The four steps above are how you get out of it before five years go by.
