About Engineering Velocity For Investors For Founders Data & Methodology Tools & PricingAbout Engineering Velocity
What is engineering velocity?
Engineering velocity is a measure of how quickly and consistently a startup's engineering team ships code. GitDealFlow calculates it using public GitHub commit activity across four dimensions:
- Commit volume — total commits in a rolling 14-day window
- Active contributors — unique developers committing code
- Contributor growth — rate of new contributor onboarding
- Repository expansion — new public repos being actively developed
The resulting velocity change is expressed as a percentage increase or decrease compared to the previous 14-day period. Learn more at our full methodology page.
How is engineering velocity measured?
Engineering velocity is calculated by analyzing public GitHub commit data over rolling 14-day windows. The measurement has four components: raw commit volume, unique contributor count, contributor growth rate (compared to the prior window), and new repository activity. Each startup's velocity change is normalized and expressed as a percentage. A +100% change means the startup shipped twice as much engineering output as the prior period. Full methodology →
Why does engineering velocity matter for startups?
Engineering velocity is a leading indicator of startup health. High-velocity teams ship faster, iterate quicker on user feedback, and reach product-market fit sooner. For investors, it's an early signal: velocity spikes typically precede fundraise announcements by 21–47 days. For founders, maintaining strong velocity signals to investors that your team is building momentum. For a deeper look, see the full guide on engineering velocity.
What are the different signal types?
GitDealFlow classifies acceleration into four signal types, each indicating a different pattern of startup activity:
- Deploy Frequency Spike — rapid increase in deployment cadence, often signaling process/tooling improvements
- Engineering Hiring Burst — sudden increase in new contributors, indicating team growth
- Infrastructure Buildout — creation of infrastructure repos, configs, and deployment pipelines (scaling)
- Framework Migration — major dependency and architecture changes (technical debt cleanup)
Each signal type has a different lead-time profile for fundraising. See signal types comparison →
What sectors does GitDealFlow cover?
GitDealFlow tracks startups across 20 sectors: AI/ML, Healthcare, Fintech, Enterprise SaaS, Web3, E-commerce Infrastructure, Data Infrastructure, Robotics, Legal Tech, HR Tech, PropTech, AgTech, Gaming, Space Tech, Social & Community, Supply Chain, EdTech, DevTools, Cybersecurity, and Climate Tech. Each sector has its own velocity trends and benchmarks. See all sectors →
For Investors
How do VCs use velocity signals?
VCs use engineering velocity signals to build forward-looking deal pipelines. By monitoring startup GitHub activity — commit spikes, contributor growth, infrastructure buildouts — VCs spot acceleration before fundraise announcements. This allows them to reach out during the 21–47 day lead window, before the competitive process attracts every other firm. Many leading VCs use GitDealFlow to supplement their sourcing workflow alongside platforms like CB Insights and Crunchbase.
What's the lead time before a funding round?
Peer-reviewed research documented in SSRN working paper 6606558 found that engineering velocity spikes precede fundraise announcements by a median of 31 days, with a range of 21–47 days. The lead time varies by: sector (healthcare has longer lead times than web3), company stage (seed rounds show tighter correlation), and signal type (infrastructure buildouts lead longer than deploy spikes).
How is scout score calculated?
Scout Score (0–100) measures a GitHub user's ability to identify breakout startups early, based on their starring history on GitHub. Users who starred startups before they became unicorns receive higher scores. The algorithm cross-references a curated list of validated unicorns and tracks when each user starred them.

How does GitDealFlow compare to other VC tools?
GitDealFlow is unique because it's based on public GitHub data — not proprietary data sources or manual research. This makes it transparent, always current, and accessible to anyone. Compare to CB Insights, Crunchbase, PitchBook, Tracxn, Dealroom, and Grata on our comparisons page.
Can I integrate GitDealFlow into my existing deal flow tools?
Yes. GitDealFlow offers multiple integration surfaces: a JSON API (signals.gitdealflow.com/api/signals.json), MCP server (npx -y @gitdealflow/mcp-signal) for AI coding assistants, A2A endpoint for multi-agent orchestration, OpenAPI 3.1 spec, and CSV exports. All are free and require no API key. See API docs →
For Founders
How do founders check their startup's velocity?
Founders can use the free Velocity Checker at gitdealflow.com/check-velocity. Enter your GitHub organization or repo slug to see: commit cadence over rolling windows, contributor trends and growth rate, acceleration signals, and comparison to sector benchmarks. No login or registration required — results are instant.
How do startups appear in the dataset?
Startups appear automatically if they have a public GitHub organization with active development. There's no submission or application process. GitDealFlow's curation algorithm identifies startup GitHub orgs across 20 sectors. If your startup is missing, it likely means the dataset hasn't identified your organization — try checking your GitHub org's activity or reach out via Telegram.
How can founders improve their engineering velocity?
Improving velocity starts with consistent, visible engineering output. Practical tactics that work:
- Ship code daily — even small commits maintain momentum
- Increase CI/CD frequency — automated deployments amplify output
- Open-source useful components — increases your public GitHub presence
- Maintain steady contributor growth — onboard new team members regularly
- Avoid feast-or-famine commit patterns — consistent cadence beats spikes
For more context, see our guide for founders →
Can founders use velocity data to time their fundraise?
Absolutely. Founders can monitor their own velocity trends on GitDealFlow to understand how investors see them. A rising velocity trend over 2–4 weeks signals strong fundraising positioning. We recommend maintaining or increasing velocity for at least 3 weeks before starting the fundraise process, as investors increasingly check these public signals before first meetings.
Is my private code safe? Do you read code?
Yes — we read no code ever. GitDealFlow only accesses public metadata: commit counts, contributor counts, and repository names from public GitHub API endpoints. We never clone repositories, inspect code, access private repos, or use any authenticated endpoints that could reveal proprietary code. Privacy and security by design.
Data & Methodology
Where does the startup data come from?
All data comes from public GitHub API events. GitDealFlow's pipeline regularly fetches commit activity, contributor profiles, and repository metadata for ~4,200+ startup GitHub organizations. No private repositories, internal metrics, or proprietary data sources are ever used. The dataset is fully reproducible from public data. See methodology →
How often is the data updated?
The dataset is refreshed weekly from public GitHub API events. Each refresh captures a rolling 14-day window of commit activity. The data typically updates every Sunday, with fresh results available by Monday morning UTC. Follow the RSS feed for update notifications.
