Gemini How It Works
The scenario: you found a fintech startup you want to fund. $3M Seed, you are writing $1M as lead. You need $2M more from co-investors who will add value, not just capital.
Your AI agent queries Harmonic: 'Find investors who have funded payment infrastructure startups at Seed stage in the last 24 months.' Harmonic returns 45 investors , micro-funds, angels, and small institutional funds.
The agent filters by check size ($250K-750K range for this round), sector match (fintech / payments), and portfolio quality (did their previous payment investments survive?).
That narrows to 12 strong co-investor candidates. For each, Harmonic shows their portfolio: Investor A funded PayStack (acquired by Stripe $200M), PayFlow (Series B), and ClearPay (operating).
That is a payments specialist with exits. Investor B is a former Stripe executive turned angel , writes $500K checks, sits on 4 fintech boards.
Investor C is a European fintech fund , adds geographic expansion value. Apollo finds their contact details: verified email, phone, LinkedIn.
The agent creates 12 contacts in Folk with full context: investor name, fund name, check size range, portfolio companies, sector focus, and your relationship status ('Cold' / 'Warm intro available' / 'Met before').
You start outreach. Within 2 weeks, you have soft commits from 3 co-investors. The round closes because the syndicate made sense , not because you scrambled.
Connector Orchestration: 3 Connectors, one intelligent agent
Connect Harmonic, Apollo and Folk Connectors so your AI agent identifies co-investment partners through Harmonic (which investors fund similar startups, what their portfolio overlap looks like, who leads at your stage), finds their direct contact details through Apollo, and tracks the syndication relationships in Folk CRM. You want to lead a $3M Seed round. You are writing a $1M check. You need 2-3 co-investors for the remaining $2M. But not just any investors , you want partners who add value: an operator angel who scaled a similar company, a sector-focused micro-fund, and a strategic corporate VC. The agent maps who invested in similar companies, finds their contact details, and tracks your outreach. Your round closes because you brought the right syndicate, not because you mass-emailed your network.

Superpowers you didn't know your AI had
The Vinkius catalog gives your agent access to 5,800+ Connectors and the intelligence to combine them. Imagine never logging into another dashboard. Your AI handles the work across all tools, in one conversation. That's what this connectivity layer 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 all platforms.
Contextual Reasoning
Each 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 Connectors once, and your agent handles the rest. Each time, without intervention.
Made for
exactly this
Your AI agent taps into the entire Vinkius AI Connectors to handle these for you. You describe what you need. It does the rest.
Seed-stage lead investors who need to fill the remaining allocation in a round with value-add co-investors matched to the startup's sector and stage
Emerging fund managers building their co-investment network who need to identify and connect with other early-stage investors for deal syndication
Angel syndicate leads structuring SPVs who need to find 5-10 co-investors for a specific deal with matching sector expertise and check size
VC associates supporting partners with round filling who need to systematically identify and reach out to potential co-investors for active deals
Frequently Asked Questions About This Connector Orchestration
Which Connectors do I need for this workflow?
Three: Harmonic, Apollo and Folk. 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 Connectors and paste a prompt.
Is this for lead investors only?
Primarily, yes. The lead investor typically fills the round by bringing co-investors. But the workflow also works for non-lead investors who want to identify who else is likely to participate , useful for understanding round dynamics.
Can I search for angel investors specifically?
Yes. Harmonic and Apollo distinguish between institutional funds, micro-funds, and individual angel investors. Specify in your prompt: 'Find angel investors' or 'Find micro-funds under $50M AUM.'
Is investor contact data reliable?
Apollo provides professional contact data from business networks. Verify email deliverability before cold outreach. For investors you share mutual connections with, a warm intro always outperforms a cold email.
How quickly can I fill a round with this workflow?
The data pull takes minutes. The relationship-building takes weeks. This workflow compresses the identification and outreach phase from weeks to days. The actual commitment timeline depends on the investors' decision process and your deal's attractiveness.
