Stop blasting.
Start activating.

Upload any warm list — conference scans, webinar registrants, demo no-shows. uStack Outbound researches every contact, tells you who matters and why, drafts personalized outreach in your team's voice, runs the follow-up, and classifies replies. You approve. We do the rest.

Every claim cited.

No hallucinated meetings. No made-up news. Every reason links to a source you can click — hiring posts, funding announcements, engineering blogs, conference attendance.

Every lead ranked, with reasons.

A fit score you can explain. Sort 200 contacts by who matters most — see exactly why each one ranks where it does. Stop guessing which ones to call first.

Every send approved by a human.

Inbox-style queue, Cmd+Enter to approve, sends through your own mailbox. Nothing leaves your queue without a click.

How it works

Six layers between an upload and an inbox reply.

// 01 · drop the list

Upload your warm contacts

CSV, paste, or hand off from your event tool. We dedupe, validate emails, and import in seconds. Mix of people you met and names from the attendee list — both work.

// 02 · research each company

Real signals, not boilerplate

Recent news, what they ship, hiring signals, technographic match, role fit, public pain points. Web + news search, grounded extraction, sources captured for every claim.

// 03 · "why this lead" reasons

4-6 grounded reason cards per contact

No more guessing. Each contact gets specific reasons — "Hiring 3 SREs in Q2", "Raised $25M Series B in March", "Uses Postgres + Kubernetes", "Director of Engineering — decision-maker for tooling". With sources.

// 04 · fit + urgency score

Ranked, explainable, sortable

Every contact gets a Fit score and an Urgency score derived from the reason cards. Sort your 200-contact list by who matters most — the top 10 are your call list for the week.

// 05 · drafts in your voice

Day 1 · Day 5 · Day 15

Three-step sequence written in your team's voice. Each step references something specific to that prospect. The opener is the differentiator, not the signature.

// 06 · approve, send, watch the inbox

Inbox-style queue · Cmd+Enter approve · sends through your mailbox

Approve a 50-contact sequence in ten minutes. Replies route to the right rep, classify automatically (interested / objection / not-now / unsubscribe), and feed back into next week's ranking.

Use cases

Any list where the contact is already a little warm.

The pattern is the same: small list, real context, personalized outreach. uStack Outbound takes any of these inputs and produces ranked, reasoned, ready-to-send drafts.

Conference badge scans

You just got back from SaaStr / Dreamforce / re:Invent. 200 names, mix of conversations and bullet-points. Turn them into intelligent follow-ups in an afternoon.

Webinar registrants

Who actually showed up? Who downloaded the recording? Rank by engagement signal × company fit. Send the right follow-up to the right segment.

Demo no-shows

They booked, they ghosted. Re-engage with a reason — what changed in their world since the booking. Higher-quality re-engagement than a generic "checking in".

Ebook / whitepaper downloads

Asset signals intent. Combine with company research to identify the 10 of 100 worth a call this week.

Podcast / newsletter mentions

Companies your audience already heard you on. Warm intro, grounded in shared context.

LinkedIn engagement

People who liked, commented, or reshared your last 30 days of posts. Already engaged — make the next move easy.
