Startups do not lose sensitive files because people are careless. They lose them because the default tools reward speed over revoke: email attachments, forever Drive folders, and Slack uploads that outlive the deal.
This playbook is a practical secure document sharing workflow for early teams—founders, ops, and first security/legal hires—who need control without building an enterprise GRC stack first.
What “secure sharing” should mean at startup scale
- Sealed in transit and at rest — preferably encrypted before it leaves the browser
- Time-boxed access — expiry by default, not “I’ll remember to remove them”
- Revoke that actually works — unlike attachments already in five inboxes
- Evidence when asked — who opened what, without screenshots of Sent folders
Compliance Locker is built for that packet job: client-side encryption, sealed shares, and exportable vault activity. It does not replace your product roadmap—or a real compliance program.
The four packets every startup eventually shares
1. Fundraise / diligence
Cap tables, financials, customer lists, and security answers should not live as a living Drive folder emailed to every associate. Use discrete sealed sets with short expiry. See diligence rooms without a shared Drive.
2. Board packs
Draft in your collaboration suite; deliver the sealed pack with watermark and expiry. Board pack playbook.
3. Security questionnaire attachments
Answer honestly about encryption and key custody—then share supporting PDFs as sealed links, not zip bombs in email. Encryption answers guide.
4. Customer / partner MSAs and NDAs
After signature, follow-on materials need audience separation and close-out. NDA sharing checklist.
Default workflow (copy this)
- Classify: collaboration draft vs sealed packet
- Seal in a vault with client-side encryption
- Mint a share: 7–30 day expiry, optional password (sent out of band), view limits when appropriate
- Notify via email/Slack with the link only—no attachment
- Revoke or let expire when the thread dies
- Export activity if investors, customers, or auditors ask
What not to do
- Password-protected ZIP as your standing policy for everything
- One shared Drive password across the whole diligence room
- Upload board decks to Slack “for convenience”
- Claim you are “SOC 2 / HIPAA compliant” because you bought a vault
30-day rollout for a five-person company
- Week 1: list document classes that may never be attachments
- Week 2: move one live packet to sealed shares; measure friction
- Week 3: publish a one-page expiry default
- Week 4: review open shares; train whoever sends investor updates
Pricing starts with free storage and paid plans when the vault becomes real infrastructure—see pricing.
FAQ
Do early-stage startups need a document vault?
Not for every file. You need one when you start sharing board packs, diligence responses, signed agreements, or customer evidence with people outside your core team—and email/Drive starts feeling like hope as a strategy.
Can we keep using Google Drive for day-to-day work?
Yes. Keep Drive (or Dropbox/Box) for collaboration. Put the sealed subset—fundraise rooms, executed contracts, security questionnaire attachments—in a zero-knowledge vault with expiry and revoke.
What’s the minimum viable secure-sharing policy?
Three rules: (1) no sensitive attachments in email, (2) sealed links default to short expiry, (3) revoke when the deal or vendor review ends. Publish it on one page and train whoever actually sends files.
Does this make us SOC 2 compliant?
No. A vault helps with access control and evidence for documents you share. Compliance still depends on your policies, processes, and any audits you pursue.
Where should we start this week?
Pick one live packet (board deck, diligence folder, or MSA), move it into a sealed share, email only the link, and set a 7–14 day expiry. Expand from that pattern.
