As answered by people managing Joyogram and Git Deal Flow.
Joyogram's answer
We have used several services like this but never found one easy to use without an app needed, and allowing us to send beautiful group cards online that were not cheesy!
Git Deal Flow's answer:
I watched a company's commit graph spike and three weeks later they announced a Series A. The signal was right there - public, free, updating in real time. Nobody was reading it. Quant funds have known for years that public data read correctly is the best leading indicator. The problem was that nobody built the lens for investors. So I did.
Joyogram's answer
Our online group cards are beautiful and modern, nothing tacky here!
Git Deal Flow's answer:
We use GitHub engineering activity as a leading indicator for investors. While competitors like Harmonic, Dealroom, and Crunchbase rely on funding announcements, job postings, and web traffic, we track commit velocity, contributor growth, and repository expansion - signals that appear weeks before a startup shows up on anyone's radar. The data is public but nobody else packages it for investors.
Joyogram's answer
Our pricing allows unlimited access to everything!
Git Deal Flow's answer:
Most deal flow tools show you what already happened - a round closed, a hire was made. We show you what's happening right now in the codebase. Engineering acceleration has historically preceded fundraise announcements by 3-6 weeks. That's the difference between setting terms and chasing a deal everyone already knows about.
Joyogram's answer
Companies that want to celebrate coworkers / staff as a group
Git Deal Flow's answer:
Angel investors, seed and Series A VCs, fund analysts, and scout networks looking for data-driven deal sourcing. Anyone who wants to find breakout startups before consensus forms around them.
Joyogram's answer
NextJS / Vercel
Git Deal Flow's answer:
GitHub API for data collection, Next.js for the dashboard, Vercel for hosting, and custom algorithms for detecting acceleration patterns across thousands of startup GitHub organizations.
