RiderSign

NDAs for sell-side M&A

One Master NDA.
A short rider per deal.
Signed in days, not weeks.

Investors sign the same Master NDA on every deal and negotiate only the rider. Both sides work section by section in one place, and the CIM is released the moment both have signed.

§ 4 TermInvestor proposed

The problem

Every deal starts with the same NDA fight.

Each process means a new NDA, redlines by email, version confusion, and a CIM waiting on legal while interest cools.

Dozens

of separate NDAs per process, each with its own markup and its own email thread.

Weeks

from teaser to CIM, mostly spent chasing the next round of comments.

No view

of who has signed, who is stuck, and what each investor has asked for.

How it works

Three steps from teaser to CIM.

The banker launches the deal

Upload the teaser and the client's marked-up rider, choose who to invite first, and send a deal-specific invitation.

The investor reviews the rider

The Master NDA never changes. The investor accepts, edits or rejects each rider section, and both sides go back and forth in one place.

Both sign, the CIM is released

Each side signs. The company name, CIM and data room unlock for that investor the moment the NDA is executed.

Built for both sides

Bankers run the process. Investors review only what's new.

For sell-side bankers

Every investor's status on one page.

  • See who has viewed, who is negotiating and who has signed.
  • Answer requests section by section, with your client's fallback positions to hand.
  • Bring company counsel onto the deal team to negotiate and sign.
  • Send in batches and hold investors back for later.
  • The CIM goes out only after both signatures, never by accident.

For private equity investors

Learn the Master NDA once.

  • The same Master NDA on every deal, so you review only the rider.
  • Propose changes section by section instead of redlining a whole document.
  • Add your deal team and counsel to each invitation.
  • The CIM and data room arrive the moment the NDA is signed.
  • Always free for investors.

Security

Deal information stays where it belongs.

RiderSign is built for confidential processes from the first line of code.

Nothing before signing

Investors never see the company name, CIM or data room until their NDA is executed.

Private by default

Documents are stored privately and opened only through short-lived links.

Full audit trail

Every view, download, round, signature and pass is recorded.

US data hosting

Data is stored in the US, encrypted in transit and at rest.

Pricing

Simple, per deal. Free for investors.

Per deal

$1,000 at launch

Includes two years of hosting, then $500 a year until the deal is archived. The bank pays; investors are always free.

  • Unlimited investors and rounds
  • Deal team and outside counsel included
  • Executed NDAs and audit trail kept for the life of the deal
