Script Capital Backs Rappo to Tackle 0→1 GTM for Technical Founders

Excited to announce that Rappo has raised funding from AJ Solimine at Script Capital. It’s been incredible working with AJ since Day 0—a true first-check investor who takes a leap of faith on bold founders and moves fast.

It all started with a cold email I sent to AJ asking for feedback.

That initial outreach turned into a partnership—he ended up investing in us 🙂

“You’re building a network that creates the shortest path between technical founders and their ideal customers. Today it’s for GTM challenges, tomorrow you’ll use the same network to solve other problems.”

That’s exactly how I’ve been explaining Rappo ever since.

Why We’re Building Rappo

The Personal Journey: As a technical founder of a database startup, I experienced firsthand how difficult 0-1 GTM is, despite having strong product traction, funding from tier 1 investors, and 1,500+ GitHub stars.

The Broader Challenge: With AI making it cheaper to build software, the real challenge has shifted from “how to build” to “what to build”, “for whom”, and most critically—“how to sell it.”

Current Solutions Are Broken: The standard playbook (introductions from investors/friends, cold emails, sales agencies) is unreliable and these channels are saturating quickly. 0-1 GTM remains one of the hardest problems with surprisingly little systematic support.

What Rappo Does

Rappo connects early-stage technical founders directly with engineering champions at growth-stage companies for customer interviews, market research, use-case brainstorming, and design partnerships.

We handle the entire process end-to-end: onboarding, discovery, recommendation, scheduling, conferencing, and follow-up actions. Champions get streamlined vendor discovery and networking opportunities (angel investing, advisory roles), while founders get direct access to their ideal champions.

Current Traction

Strong technical startups are already using Rappo to accelerate their GTM:

• Kombai (backed by Foundation Capital)
• Sequin (backed by Kleiner Perkins)
• Cardinal (backed by CRV)
• 35+ others between seed and Series A

Our champion network includes engineering leaders from Webflow, GitLab, Instacart, GEICO, and many others who connect with startups daily.

📊 By the numbers: 150+ successful engagements facilitated and growing strong.

What’s Next

In the coming days, we’ll be sharing case studies of how these technical startups are using Rappo to refine their product roadmap, test messaging, and find design partners.

Thanks again to AJ and the entire Script Capital team for believing in our vision! 🙏
