Built by someone who
couldn't afford to lose a deal
Korveln started as an internal tool for one founder trying to sell cybersecurity services to C-suite executives on LinkedIn. It worked. Then it became a product.
I founded NullStrike Security, a penetration testing firm. Our buyers were CISOs, CTOs, and VP-level security leaders at companies with real security budgets. Getting those people on the phone is hard. Getting them to reply to a cold LinkedIn message is nearly impossible.
I surveyed my ICP directly to understand how they actually made purchasing decisions. The pattern was consistent: they bought from people they already had a relationship with, or from warm introductions through people they trusted. Cold outreach — regardless of how well it was written — produced nearly nothing from that audience.
But LinkedIn was where those relationships actually lived. Every comment, every reply, every piece of shared content was a signal. The problem was that tracking those signals manually across dozens of active relationships was impossible to do consistently. I would follow up with someone at exactly the right moment, then forget about three others who went quiet. I had the activity. I just could not see it.
So in early 2026 I built a tool to fix that for myself. It captured my LinkedIn interactions automatically, scored each relationship by warmth, and told me who to talk to today instead of making me figure it out from memory. Connection acceptance rates went up. Response rates went up. I stopped losing deals to relationships I had forgotten to nurture.
That internal tool became Korveln. It now handles all of my LinkedIn sales, and it does the same for the founders, sellers, and consultants who use it today. If your buyers live on LinkedIn and cold outreach does not work for them, this is what we built for you.
Cold outreach fails at the top of the market
The ICP survey that led to Korveln surfaced a pattern that most sales teams already feel but rarely measure: the higher the seniority of your buyer, the less cold outreach works. C-suite and VP-level buyers are flooded with identical cold messages. The ones that get responses share one thing — an existing relationship, or a warm introduction from someone they already trust.
LinkedIn is where those relationships are built. Every like, comment, reply, and shared content thread is a touch that either strengthens or lets a relationship decay. The problem is that no existing tool was built to track that layer. CRMs track meetings and pipeline stages. LinkedIn itself shows you a feed, not a relationship map.
Korveln fills that gap. It makes the relationship layer visible — who is warm, who is going cold, who just became a champion, and who is the fastest path into the account you are trying to break into.
Our principles
Zero manual work
If you have to remember to log it, it will not get logged. Korveln captures everything in the background so you can focus on the actual conversations that matter.
Your data, your rules
Encrypted, private, and fully under your control. We never sell data, never share it, and you can export or delete everything at any time.
Signal, not noise
Every metric, alert, and score exists to help you make one specific decision. If it does not help you act, it does not show up in your dashboard.
Depth when you need it
The dashboard gives you clarity in seconds. When you need to dig deeper into network paths, sentiment trends, or account coverage, the depth is there.
