Run the whole sell-side process in one place

Teaser, buyer list, NDAs, data room, book building — dealOS turns a deck into a running sell-side process and tracks every buyer from first contact to offer.

Why dealOS for sell-side

The mandate workflow, end to end

Everything an advisor or founder-led process needs between mandate and offers.

Teaser from the deck

Upload the pitch deck or IM and dealOS drafts an investor-ready teaser you can edit inline or with AI — no starting from a blank page.

Buyer and investor matching

Match the opportunity against 18,000+ investors and buyers by sector, stage, geography and ticket size — with verified contact emails.

Outreach from your inbox

Approach the list from your own email account, paced for deliverability, with delivery and engagement tracked per buyer.

NDAs before access

Gate the detail behind an NDA flow — who's signed, who's sitting on it, and who gets access to what, tracked automatically.

Data room included

Share diligence materials through a structured data room with per-buyer access control — no separate VDR subscription to stand up.

Engagement to offers

Teaser views, document downloads and discussions per buyer, through book building to offers — one live picture of the process.

How it works

From mandate to a running process in a day, not a month.

Approach the market

Send the teaser from your own inbox, gate detail behind NDAs, and open the data room to signed parties.

Frequently asked questions

 

What does sell-side M&A process software cover?

The full workflow of selling a company or raising against a mandate: teaser creation, buyer/investor matching and outreach, NDA management, a data room for diligence materials, and per-buyer engagement tracking through to offers.

How does buyer matching work?

dealOS matches the opportunity against a base of 18,000+ investors and buyers using sector, stage, geography and ticket-size criteria, and returns a ranked shortlist limited to contacts with verified email addresses.

Is a data room included?

Yes — deals include a structured data room with per-buyer access control, gated behind the NDA flow, so diligence materials are shared from the same workspace that tracks the process.

Who uses it?

Corporate finance boutiques and M&A advisors running sell-side mandates, and founders running their own process — anyone who wants the teaser-to-offers workflow in one system instead of five tools.
