In 2025, one accidentally forwarded cap table or leaked valuation model can erase hundreds of millions in enterprise value overnight. Yet many companies still use everyday cloud storage for financing due diligence, M&A, and IPO document sharing—only to face irreversible leaks, regulatory fines, and complete loss of control. BestCoffer Virtual Data Room (VDR) and generic cloud storage were never designed for the same job: one is a zero-trust transaction fortress; the other is a convenient notepad for daily files.

Q: Can’t I just use cloud storage + manual watermarking and save cost?
A: Manual watermarking is easily removed, and once downloaded there is zero enforcement. BestCoffer’s dynamic watermark + IRM survives screenshots and remains enforceable forever.
Q: Is the price difference really justified?
A: When a single leak can cost 5–15% of deal value (hundreds of millions), BestCoffer’s cost is less than 0.1% of typical transaction size—cheaper than your legal counsel’s hourly rate.
Q: My investors say “just send via cloud link” – is that safe?
A: 68% of reported M&A leaks in 2024–2025 originated from generic cloud links. BestCoffer eliminates that vector entirely.
Q: We are a startup; do we really need a full VDR?
A: The most expensive rounds (Series B+) have the most to lose. Unicorns like OpenAI, Anthropic, and xAI all used enterprise VDRs from day one of their mega-rounds.
Q: How fast can we switch from cloud storage to BestCoffer?
A: Most clients migrate all files and go live in under 4 hours with our dedicated onboarding team.
