No description of Trace yet.
Most cold outreach gets ignored because the timing is off. We all know the standard process. You export a thousand leads from Sales Navigator, send a generic template, and hope for a reply. But usually, you just get ignored. The problem is that legacy tools give you static lists like job titles...

As answered by people managing Trace and Sonarly.
Sonarly's answer:
Most outreach tools are just "databases" that give you static lists of leads (Job Title + Industry). Sonarly is a Signal Engine. We don't just tell you who a lead is; we tell you when to contact them. We monitor real-time trigger events like hiring sprees, funding rounds, and recent LinkedIn posts to identify the exact moment a prospect is ready to buy.
Sonarly's answer:
Three reasons:
Timing over Volume: Competitors let you spam 1,000 people. We help you contact the 50 who actually have a need right now.
Context, not Templates: Our AI doesn't write generic fluff. It uses the specific signal found (e.g., "Saw you are hiring a Head of Sales") to write a hyper-relevant opener automatically.
GDPR & Trust: Unlike many "grey-zone" scraping tools from the US, we are a German GmbH built with strict European data compliance in mind.
Sonarly's answer:
B2B Founders, Heads of Sales, and Growth Hackers who are tired of the "Spray and Pray" approach. They don't have time to manually research leads for hours, but they refuse to send low-quality spam. They want high-converting, signal-based outreach on autopilot.
Sonarly's answer:
My co-founder Maurice and I were sick of deleting bad cold DMs from our own inboxes. We realized the problem wasn't "cold outreach"—it was the lack of relevance. We tried doing it manually (checking funding news, scanning posts), and it worked perfectly, but it took way too much time. So, we built Sonarly to automate the "manual research" process that top 1% sales reps do, making it accessible to everyone.
Sonarly's answer:
We use a proprietary Real-Time Signal Monitoring Engine to scan LinkedIn and external data sources. On top of that, we layer a specialized Generative AI model tuned specifically for B2B sales context to transform raw data signals into natural, human-sounding conversation starters.
