Gemini How It Works
Here is the signal: Harmonic tracks startup traction , not just funding announcements, but the leading indicators. A company's engineering team doubled in 3 months.
They launched on Product Hunt and hit #1. Their LinkedIn mentions spiked 400%. They posted 5 open roles in the last 2 weeks.
These signals precede the fundraise announcement by 4-8 weeks. Your AI agent queries Harmonic for startups showing these signals in your target sector and geography.
For each match, it enriches the company profile: founding date, team size, last known round, estimated ARR range. Then the agent uses Hunter to find the founder's email , verified, deliverable, not a generic info@ address.
It sends a Brevo email: personalized with the company name, a specific reference to the traction signal ('Saw your engineering team grew from 8 to 18 in Q1 , that kind of hiring velocity means you are likely thinking about your next round'), and a direct ask for a 20-minute conversation.
The founder receives outreach that references something specific about their company , not a template blast. That is the difference between a reply and a delete.
MCP Server Orchestration: 3 MCP Servers, one intelligent agent
Connect Harmonic, Hunter and Brevo MCP servers so your AI agent discovers high-traction startups through Harmonic's intelligence engine, finds verified founder email addresses via Hunter, and sends personalized outreach emails through Brevo. Investors who see deal flow only after startups announce their raise on Twitter miss the early window. This workflow finds companies showing traction signals , hiring spikes, product launches, press mentions , before the round is announced. The deal is in your inbox while other funds are reading the TechCrunch headline.

Superpowers you didn't know your AI had
The Vinkius catalog gives your agent access to 4,700+ MCP servers and the intelligence to combine them. Imagine never logging into another dashboard. Your AI handles the work across every tool, in one conversation. That's what this infrastructure was built for.
Cross-Platform Intelligence
Your agent doesn't just connect to tools. It understands the relationships between them. Data flows where it needs to go, automatically, with full context preserved across every platform.
Contextual Reasoning
Every decision your agent makes considers the full picture. It reads CRM data, checks calendars, reviews conversation history, and acts on everything at once. Not step by step. All at once.
Productivity at Scale
What used to take 45 minutes across five different dashboards now takes one sentence. Your agent runs the entire workflow end to end while you focus on decisions that actually matter.
Zero-Config Reliability
No API keys to paste. No webhooks to configure. No YAML to debug. Connect your MCP servers once, and your agent handles the rest. Every time, without intervention.
Made for
exactly this
Your AI agent taps into the entire Vinkius MCP catalog to handle these for you. You describe what you need. It does the rest.

Frequently Asked Questions About This MCP Server Orchestration
Which MCP servers do I need for this workflow?
Three: Harmonic, Hunter and Brevo. Connect all three to your AI client before running any prompt from this page.
Does this work with Claude Desktop, Cursor or Windsurf?
Yes. Any AI client that supports the Model Context Protocol works , Claude Desktop, Cursor, Windsurf, Cline and others. Connect the MCP servers and paste a prompt.
What makes Harmonic different from Crunchbase?
Crunchbase tracks announced funding rounds. Harmonic tracks traction signals , hiring spikes, product launches, traffic growth , that precede fundraising. You see the company before the round is public.
Is cold email outreach to founders appropriate?
Founders expect investor outreach. The difference between welcome and unwelcome is relevance. An email referencing a specific company milestone gets a response. A template blast gets deleted. This workflow builds the specificity that makes outreach welcome.
Is founder contact data secure?
Hunter finds publicly available professional email addresses. Brevo sends emails through your authenticated account. Vinkius does not store any contact data. All communications are between you and the founder.
Can I customize outreach by fund thesis?
Your prompt controls the thesis. Ask for 'climate tech startups in Europe with hiring signals' or 'AI infrastructure companies in the US with product launches.' The agent tailors the outreach to match your investment focus.
