How to get on KillerStartups — the oldest startup directory

KillerStartups launched in 2006, which in internet years makes it practically ancient. It's been through multiple ownership changes and design iterations, but it's still running, still indexing new submissions, and still carrying the domain authority that comes with nearly two decades of inbound links.

For a SaaS founder in 2026, it's worth fifteen minutes — probably more than you'd expect.

Quick answer: Submit to KillerStartups at killerstartups.com — it's free, takes about 15 minutes, and goes through a light manual review typically within a few days to two weeks. The main return is a backlink from a domain that's been accumulating authority since 2006, which has real value early in your product's life when your backlink profile is thin.

What is KillerStartups and who uses it?

KillerStartups is one of the original startup directories, predating Product Hunt by about eight years. It lists startups and early-stage products across all categories, with a mix of editorial staff picks and community-submitted entries. The site doesn't have the same cultural cachet it did when it launched, but it maintains a steady stream of traffic from people specifically looking for new tools and startups.

The audience skews toward early adopters, other founders, and people in the startup ecosystem — investors, journalists, and potential partners who browse startup directories as a matter of professional habit. It's not a large audience by any modern metric, but it's a relevant one if your product has a B2B or developer angle.

From a pure SEO standpoint, KillerStartups has accumulated substantial domain authority over nearly two decades. A listing there contributes a real backlink to your domain authority profile, particularly in the early months of your product's life when you're building from zero.

How do you submit to KillerStartups?

The submission process is straightforward. Visit killerstartups.com and locate the "Submit a Startup" option — the path has changed over the years but is typically linked from the main navigation or footer. You'll fill out a standard form covering your product name, URL, tagline, description, category, and founding year.

The description is the part most founders rush and shouldn't. Write 150 to 200 words that cover what the product does, who it's for, and what makes it different. Avoid marketing language — directory editors have seen thousands of "disruptive" and "game-changing" products. Plain language about a specific problem and a specific solution is more credible and more likely to get approved quickly.

Category selection matters for internal search. Choose the most specific category that fits rather than the broadest one. "Marketing Automation" will surface to more relevant searches than "Software" even if technically both apply.

What do you actually get from a KillerStartups listing?

The primary value is the backlink and the indexed listing. KillerStartups pages are crawled by Google, so your listing will eventually appear in search results for your product name — useful social proof when people Google you before signing up.

Direct traffic from KillerStartups tends to be modest. Don't expect a traffic spike comparable to a successful Product Hunt launch or Hacker News post. The discovery path is lower-intent: someone browsing startup directories rather than actively searching for a solution. Conversion rates from directory-browsing traffic are typically lower than from search or direct outreach.

The compounding value comes from being listed across multiple directories over time. KillerStartups is one piece of a distribution strategy, not a standalone channel. A listing here, combined with listings on other directories, builds the kind of broad online presence that shows up when journalists, investors, or potential customers do due diligence searches.

What should you prepare before submitting?

Logo in multiple formats (PNG, minimum 200x200px), a clear 160-character tagline that explains exactly what the product does, a longer description ready to paste, and your product category decided in advance. Screenshots are valuable if the submission form accepts them — product screenshots consistently outperform logo-only listings in click-through rates.

Have your website fully functional before submitting. Several directories including KillerStartups do light manual review, and a site that's under construction or returns errors will get rejected or delayed. If you're launching in stages, wait until your core product pages are live before submitting to directories.

What if your submission gets rejected or stalls?

Rejections from KillerStartups are rare but not unheard of. The most common reasons: a broken or parked-looking landing page, a description that reads as spam (all caps, excessive exclamation points, unverifiable claims like "#1 in the world"), or a product category that doesn't clearly match anything the site covers (adult content, MLM-adjacent products, and anything resembling a scam get filtered out by editorial review).

If two weeks pass with no response, don't assume it was silently rejected — manual review queues on older, lower-traffic directories are inconsistent, and a listing can sit unprocessed for a month during a slow period. Resubmitting with a slightly revised description (not identical — some systems flag exact duplicate submissions) is a reasonable next step after three to four weeks. If you have a contact form or support email listed on the site, a short, polite follow-up referencing your submission date is also fine; directory editors running sites like this are often a single person or small team, and a nudge is normal rather than annoying.

Is a nearly-20-year-old directory actually worth your time versus newer options?

This is the honest tradeoff worth naming. Newer directories launched in the last two to three years often have better design, more active communities, and in some cases more current traffic. KillerStartups doesn't compete with those on user experience or discovery volume.

What it offers instead is accumulated link equity that no new directory can replicate. A domain that's been continuously indexed since 2006, surviving multiple redesigns and ownership changes, has a backlink profile and trust signal that Google's algorithms weight differently than a domain registered last year — regardless of how polished either site looks today. For a founder thinking purely about near-term referral traffic, a newer, more active directory is probably a better use of fifteen minutes. For a founder thinking about the cumulative weight of their backlink profile over the next two to three years, an old, low-maintenance, free listing like this is close to zero-risk and modestly positive-value. The right move for most early-stage founders is both: newer directories for discovery, older ones like KillerStartups for the compounding authority signal.

Frequently Asked Questions

Is KillerStartups still active in 2026? Yes — the site continues to accept submissions and publish new listings. It's not growing at the rate of newer directories, but it's maintained and indexed, which is what matters for SEO purposes.

How long does approval take? Typically a few days to a couple of weeks for editorial review. Free submissions are reviewed manually, which takes longer than automated directories. Check back after a week and resubmit if your listing hasn't appeared.

Is there a paid option that speeds up the process? KillerStartups has offered paid featured listing options in the past. Check the current submission page for any paid tiers — the specifics change over time. For most early-stage founders, the free listing is fine.

Does the backlink from KillerStartups actually help SEO? Yes, especially early on when your domain authority profile is thin. A link from a site that's been around since 2006 and has accumulated significant authority is more valuable than a link from a directory launched last year. The effect is modest but real and permanent.
