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 or company size. They tell you who exists, but they do not tell you who is ready to buy right now.

We built Sonarly to fix this.

Sonarly is a signal-based outreach engine. We do not just hunt for people. We hunt for buying signals. Instead of a static database, our system monitors your ideal customer profile for real-time events that indicate intent.

What Sonarly actually does:

  • Monitors Real-Time Signals: We scan for hiring sprees, funding news, tech stack changes, and relevant LinkedIn posts.
  • Provides Context: We identify exactly why a prospect is a good fit today. For example, knowing they just hired a VP of Sales gives you a reason to reach out.
  • Writes Relevant Messages: Our AI generates a personalized opener based on that specific signal. It writes about the news or the post, rather than using a "hope this finds you well" template.
  • Safe Automation: We are a German GmbH and built the platform to be fully GDPR compliant and safe for your LinkedIn account.

This tool is for founders and sales leaders who are tired of the numbers game and want to build a pipeline based on relevance.

We are currently in Private Beta. Join the waitlist to secure your spot as a Founding User.

Questions & Answers

As answered by people managing Webhook Stream and Sonarly.

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

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.

What's the story behind your product?

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"โ€”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.

Which are the primary technologies used for building your product?

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.

Who are some of the biggest customers of your product?

Sonarly's answer:

Private Beta Cohort (Stealth Mode Startups)

Early Adopter B2B Agencies

(Currently onboarding our exclusive "Founding Users" for the Q1 2026 public launch)
