Fundraising tooling fails when it optimizes for deck polish instead of evidence. This page tracks open-source skills, plugins, and agents that help you find the right capital, keep a clean data room, and stop re-inventing the same investor spreadsheet every month. Last updated: August 31, 2026. Reviewed weekly. Pair this with our startup events, grants & fundraising deadlines living page for dated non-dilutive opportunities.

Which tools help find investors and grants?

5 listed

OpenVC (export + OSS helpers)

Rolling
What it is
Investor list & filters
License / cost
Freemium + API

Not fully OSS, but the best free ICP filter for pre-seed. Export and merge with your CRM; do not live inside someone else's pipeline forever.

Crunchbase alternatives (DIY)

Rolling
What it is
Community enrichment scripts
License / cost
Mixed

Roll your own when you need Canadian micro-VCs CB Insights misses. Maintenance cost is real — budget a Friday cleanup.

Grant matching spreadsheets (public)

Rolling
What it is
Primary-source grant portals
License / cost
Free

Always prefer ISED / provincial primary pages over blog aggregators. Our deadlines living page re-verifies these weekly.

Open Grants data projects

Rolling
What it is
Open-data grant feeds
License / cost
Mixed

Useful for building internal alerts. Quality varies by province — Ontario and BC tend to be cleaner than ad-hoc municipal PDFs.

Harmonic-alternatives (research)

Rolling
What it is
Startup graph experiments
License / cost
Mixed

Early OSS graphs are fun demos, rarely production CRM replacements. Use for signal, not sole sourcing.

Which skills & plugins help draft pitch materials?

5 listed

PRD → pitch deck workflows

Rolling
What it does
Community pitch skills
Where it runs
Claude / Cursor

Only trust skills that take structured input (PRD, metrics), not vibes. Codalio users: start from a real PRD, not a paragraph.

Marp

Rolling
What it does
Markdown → slides
Where it runs
MIT

Fastest OSS path from written spec to deck draft. Investors still judge story, not theme fonts.

Slidev

Rolling
What it does
Dev-friendly presentations
Where it runs
MIT

Better than Marp when your deck includes live product screenshots and code snippets.

Gamma export + OSS cleanup scripts

Rolling
What it does
Post-process exported decks
Where it runs
Mixed

Many founders generate in Gamma, then lose editability. Keep a markdown source of truth alongside any pretty export.

Financial model templates (OSS)

Rolling
What it does
Community SaaS models
Where it runs
Mixed

Download three, delete two, keep one driver-based model. Complex models impress nobody if ARR is zero.

Which agents help with cap table & data room hygiene?

5 listed

Cap table templates (YC / OSS)

Rolling
What it is
Spreadsheet cap tables
Best for
Pre-seed

Good until you take priced round with pro rata. Then pay for dedicated cap table software or counsel.

Docuseal

Rolling
What it is
Open-source e-sign
Best for
SAFEs & advisor agreements

Self-host when you are sending more than five docs a month. Cheaper than DocuSign, still not legal advice.

Paperless-ngx

Rolling
What it is
Document management
Best for
Data room prep

Scan/OCR + tags beat a Google Drive dump named "Final_v7_really_final."

Nextcloud

Rolling
What it is
Self-hosted file share
Best for
Investor data rooms

Heavier setup, full control. Use when privacy policy or enterprise buyers require it.

Vaultwarden

Rolling
What it is
Secrets / credential share
Best for
Team fundraising ops

For sharing login to data room tools without Slackting passwords. Not a substitute for proper access control.

Frequently asked questions

Should I buy a fundraising CRM?
Not before you have 20+ active investor conversations. A spreadsheet with stages beats a $200/mo seat you forget to update.
Are open-source cap tables safe?
Templates are fine pre-priced round. After that, use software your lawyer recognizes — cleanup is expensive.
How does this relate to the grants deadlines page?
This page is tools and skills. The deadlines page is dated opportunities. Use both; neither replaces reading primary source terms.
How often is this page updated?
Weekly. We remove tools that stop shipping or lose maintainer activity.
