How to Approach These Investors
Knowing the list is step one. Getting their attention is the hard part. Here is what we have learned from founders we have worked with:
- Get a warm introduction. Cold outreach works but warm intros are 10x more effective. Use your network, advisors, or LinkedIn to find someone who knows the partner.
- Have a working product. A prototype in hand changes the conversation from "maybe" to "let me see it." This is where we come in. We build MVPs that get founders into rooms.
- Document your customer conversations. Investors want to see that you have talked to real people with real problems. Bring quotes, not assumptions.
- Know what you are asking for and why. State the amount, the use of funds, and the milestones. Vague asks get ignored.
- Pitch the investor, not the product. Investors invest in people who execute. Show your conviction, your speed, and your domain knowledge.
What to Have Ready Before You Pitch Any of Them
- A working MVP deployed to a live URL
- 3 to 5 customer conversations documented with quotes and outcomes
- At least one signed letter of intent or pilot agreement
- A one-page financial model showing use of funds and milestones
- A security assessment of your product (investors are checking this now)
- IP assignment documents for all contributors
Building the product is the first step. If you need an MVP that gets you in the room with these investors, we build those.
