Each checklist below turns one part of the evaluation process into a set of checks you can run before you invest, with nothing left to memory. The GitHub Due Diligence Checklist is the one most investors are missing: it verifies execution, team scaling, and product direction from public GitHub evidence, the record the founder did not write for you. Pair it with the traditional checklists below for a complete review. ## Checklists ### [GitHub Due Diligence Checklist](https://gitdealflow.com/checklists/github-due-diligence-checklist) 21 checks across velocity, team, process, and red flags, all answerable from public GitHub data, with a scoring rubric. ### [Technical Due Diligence Checklist](https://gitdealflow.com/checklists/technical-due-diligence-checklist) The technical substance checks: does the product exist, is the team capable, and will it scale. ### [Market Due Diligence Checklist](https://gitdealflow.com/checklists/market-due-diligence-checklist) Checks for market size, competition, and timing before you invest. ### [Founder Interview Checklist](https://gitdealflow.com/checklists/founder-interview-checklist) The questions to ask founders, and what the answers reveal about conviction and capability. ### [Investment Memo Checklist](https://gitdealflow.com/checklists/investment-memo-checklist) What every investment memo must cover, from thesis and evidence to risks and decision. ### [Pre-Seed Due Diligence Checklist](https://gitdealflow.com/checklists/pre-seed-due-diligence-checklist) The checks that matter when there is no revenue to measure. ### [Seed Due Diligence Checklist](https://gitdealflow.com/checklists/seed-due-diligence-checklist) The checks for the first institutional round. ### [Series A Due Diligence Checklist](https://gitdealflow.com/checklists/series-a-due-diligence-checklist) The checks for scaling-stage execution and product-market fit. ### [Follow-On Investment Checklist](https://gitdealflow.com/checklists/follow-on-investment-checklist) The checks before you double down on an existing position. ### [Term Sheet Review Checklist](https://gitdealflow.com/checklists/term-sheet-review-checklist) The terms to read and the traps to avoid before you sign. ### [Deal Flow Sourcing Checklist](https://gitdealflow.com/checklists/deal-flow-sourcing-checklist) A weekly routine for keeping your sourcing pipeline full. ### [Portfolio Monitoring Checklist](https://gitdealflow.com/checklists/portfolio-monitoring-checklist) The quarterly checks to keep your portfolio on track. ## Explore by topic - [Learn: the full guide library](https://gitdealflow.com/learn) - [FAQ: funding stages, signals, and prediction](https://gitdealflow.com/faq) - [Step-by-step playbooks](https://gitdealflow.com/how-to) - [Glossary: one-line definitions](https://gitdealflow.com/glossary) - [Who GitDealFlow is for: 15 investor profiles](https://gitdealflow.com/for) - [Quick answers: common investor questions](https://gitdealflow.com/answers) - [Integrations: Slack, Notion, Airtable, Sheets](https://gitdealflow.com/integrations) ## How to Use This Checklist A checklist earns its place when every line maps to evidence you can obtain. The items above follow the same public-data discipline behind GitDealFlow: 350+ startup GitHub organizations tracked across 15 sectors, refreshed weekly, with breakouts identified 21 to 47 days before the round. Where a line asks about engineering execution, the evidence is usually public: commit velocity, contributor concentration, and repository expansion, all confirmable from the repository itself rather than from a pitch deck. ## Related Checklists - [GitHub due diligence checklist](/checklists/github-due-diligence-checklist) - [Seed due diligence checklist](/checklists/seed-due-diligence-checklist) - [Technical due diligence checklist](/checklists/technical-due-diligence-checklist) - [All checklists](/checklists/) A practical read-through of Investor Checklists: the dataset behind this page refreshes weekly across 350+ organizations and 15 sectors, and every figure shown traces to a public GitHub REST API pull. That matters for two reasons. Reproducibility: any number here can be re-derived from primary sources, which is the standard the published methodology sets for itself. Timeliness: engineering acceleration precedes announcements, so this page follows the data cadence rather than the news cycle, and the freshness endpoint always reports the exact pull date. If Investor Checklists is your entry point, the fastest next steps are fixed: skim the glossary for the three or four terms that anchor the topic, open the research dataset to see the raw weekly snapshots behind the summary numbers, and run one live query against the free momentum checker with a company you already know well. Seeing the signal fire on a familiar name is the quickest way to judge whether code-side sourcing belongs in your own workflow.
