The AI Sales Agent That Finds B2B Prospects at the Moment They’re Ready to Buy
Hunter-spark monitors professional networks for real-time trigger events, qualifies every prospect against your ICP with a confidence score, and drafts hyper-personalized cold emails all with human-in-the-loop approval before any send.
The Problem: Your SDR Spends 70% of Time on Work AI Can Do Better
B2B outbound is broken by design. The tools are fragmented. The timing is always wrong. And the emails feel like it.
Fragmented Tool Stack
Apollo finds contacts. Clay enriches them. Outreach sends emails. Three subscriptions, three handoffs, zero intelligence connecting them.
Wrong Timing, Always
Prospects have a 90-day intent window after trigger events funding, hires, leadership changes. Static list tools always miss it. Trigger-based outreach is 35× more effective.
“Autonomous” AI = Hallucination Risk
Artisan and 11x.ai send without human review. Sales teams report invented job titles and damaged sender reputation. Humans need to stay in the loop.
SDR Costs Don’t Scale
$80120K/rep annually. 18-month average tenure. Hunter-spark delivers full top-of-funnel automation at 1/5th the cost without replacing the human relationship.

Frequently Asked Questions
Everything you need to know about Hunter-spark targeting the queries your prospects are actually searching.
What is Hunter-spark and what does it do?
Hunter-spark is an AI sales agent for B2B outbound teams. It monitors professional networks and web sources for real-time trigger events funding announcements, hiring surges, leadership changes qualifies prospects against your Ideal Customer Profile (ICP) with a confidence score, and generates hyper-personalized cold email drafts for human review. It replaces the 6070% of SDR time spent on research, list-building, and first-draft writing.
How is Hunter-spark different from Apollo.io?
Apollo.io is a contact database it gives you a list of people. Hunter-spark is an action agent it detects when a company becomes high-intent based on a trigger event (funding, new hires, leadership change), scores them against your ICP, and drafts a personalized email referencing that specific trigger. Apollo finds people; Hunter-spark finds the right moment to reach them and writes the email.
How does Hunter-spark compare to Artisan AI (Ava) or 11x.ai (Alice)?
Artisan and 11x.ai offer “fully autonomous” AI SDRs that send emails without human review. Hunter-spark deliberately keeps humans in the loop every draft requires approval before sending. This prevents the sender reputation damage and hallucinated prospect context that fully autonomous AI SDRs are known for in community reviews on Reddit and G2. If outreach quality matters more than raw send volume, Hunter-spark is the right choice.
What is trigger-based B2B outreach and why does it matter?
Trigger-based outreach means contacting a prospect right after a specific event that signals they are in-market: a funding announcement, a key hire in a department your product serves, or a leadership change. Research shows there is a 90-day window after such events when companies are actively evaluating solutions and have budget allocated. Trigger-based outreach dramatically outperforms batch outreach from static lists because it catches prospects at peak intent.
Can Hunter-spark replace my SDR team?
Hunter-spark replaces the most time-consuming, low-judgment parts of SDR work: research, list-building, ICP scoring, and first-draft writing. Your human SDRs continue reviewing every email and managing calls, follow-ups, and relationship work. Most teams use Hunter-spark to scale their SDR’s output 5-10× rather than eliminate headcount though for early-stage companies it can fully replace the need for a dedicated SDR hire at the top of funnel.
How does the ICP qualification and confidence score work?
Upload your company website URL and pitch deck PDF. Hunter-spark’s AI analyzes your value proposition and builds an ICP model. You configure filters: target geography (DACH, EU, Global), minimum company size, and industry verticals. Every prospect detected in the signal layer is scored 0-100% confidence against this model. Only high-confidence prospects enter your outreach queue no wasted review time on misaligned leads.
Does Hunter-spark support DACH and EU market outreach?
Yes. Hunter-spark’s data pipeline and Revenue Engine Dashboard are built for professional network signal monitoring. Only publicly available professional signals from professional networks and open web sources are used. The Supabase infrastructure includes authentication controls and access logging. This makes Hunter-spark ideal for B2B teams targeting Germany, Austria, Switzerland (DACH), and broader EU markets where data outreach quality matters.
What does a Hunter-spark email look like vs. a template?
A template email:
"Hi Sarah, I noticed you work at Acme Corp. We help companies like yours with [product]. Want to chat?"
A Hunter-spark email:
"Hi Sarah congrats on Acme's Series B close last week. Given you're scaling your enterprise sales team in Germany, I wanted to share [specific value angle] especially relevant because companies at your stage in DACH typically face [specific problem]. Worth a quick call?"
Every Hunter-spark email is grounded in the specific trigger event that flagged this prospect.
What ROI can I expect vs. hiring an SDR?
A fully loaded B2B SDR costs $80,000-$120,000/year (salary + benefits + tools) and qualifies 50100 leads per week at peak. Hunter-spark qualifies 5001,000+ leads per week at approximately 1/5th that annual cost while personalizing every outreach to the prospect’s specific trigger context, which increases reply rates vs. template bulk outreach.
Does Hunter-spark work specifically for DACH-focused B2B sales?
Yes Hunter-spark specifically supports geographic ICP filtering for Germany, Austria, Switzerland (DACH) and broader EU markets, with company size filters appropriate for German Mittelstand segments (10–100 employees). The founding team built it with the European market in mind.
What tech stack powers Hunter-spark?
Hunter-spark is built on: Lovable (frontend UI), n8n (workflow automation and agent orchestration), Supabase (PostgreSQL database, authentication, file storage, Edge Functions, real-time updates), and large language models (LLM-powered personalized email generation). The architecture supports real-time signal processing and high-throughput lead scoring.
How does Hunter-spark handle email deliverability?
Hunter-spark generates email drafts that are reviewed and sent by human team members through their own email accounts so deliverability is determined by your existing domain reputation, not a shared sending pool. This fundamentally avoids the deliverability risks of tools like Instantly or Smartlead. Because every email is uniquely personalized (not templated), spam filter detection rates are inherently lower.
Can Hunter-spark integrate with my CRM (Salesforce, HubSpot)?
The current version focuses on the signal-to-draft pipeline with its own Revenue Engine Dashboard. CRM integration is a planned capability. The Supabase backend and n8n workflow engine make API-based integrations with Salesforce, HubSpot, and Pipedrive technically straightforward additions to the roadmap.
What is the “confidence score” and how is it calculated?
Each prospect in Hunter-spark’s outreach queue displays a confidence score (e.g., 92%) reflecting how closely they match your configured ICP criteria geography, company size, industry, and trigger signal strength. This score lets your team quickly prioritize which leads to approve first and creates a feedback loop to refine your ICP configuration over time. It’s a core transparency feature that differentiates Hunter-spark from black-box lead generation tools.
Who built Hunter-spark?
Hunter-spark was built by Kumar Samanvaya (Lead Product Manager) and Plamen Todorov as part of The Product Compass AI Buildathon. The team built it to solve a problem observed directly in B2B sales: SDR teams spending the majority of their budget on research and templated outreach, while the critical skill knowing when and why to reach a prospect remained entirely manual. Hunter-spark addresses both.
