* Every field on this page comes from public sources only: the YC company directory and the LinkedIn and X links each founder listed on their own YC profile. Nothing from Bookface, no scraped inboxes, no purchased data.
Our own run, founders from the two newest batches, first five days:
200 founders enrolled on X
78 DMs delivered, 9 replies
50 refused because their DMs are closed to non-followers, so those move to LinkedIn and email
X DMs from your account. No other outreach tool sends X DMs at all. Founders live there.
LinkedIn connection request, then a message once they accept, inside the weekly limit.
Email only to verified addresses, so your domains stay clean.

Sending as you
Residential IP · San Francisco

28 sentYou connect once. From then on the requests go out from your own account, the way you would send them yourself if you had the hours.
Sign in once and pick the account you want to grow.
Every request goes through a residential proxy in your city, at randomized times through the day. To LinkedIn it looks like you, on your laptop, between meetings.

X connected
DMs sent as you
Your latest post
Most founders lose the deal in the follow-up, not the pitch.
48 likes · 12 reposts · 9 new followers
Connect your X account and every new follower and everyone who likes or replies to your posts becomes a lead we can review and DM, from your account, in the same run as LinkedIn.
New followers are picked up automatically and checked against your ICP.
One click on any post starts DMing the people who engaged with it.
Follows, likes, and DMs are paced so the account keeps looking like you.
3 mailboxes sending
Weekdays, 8am to 6pm
Plug in the mailboxes you already own. Campaigns send inside the hours you set and under each mailbox's daily limit. Once someone replies, their follow-ups end.
Connect one mailbox or ten. Each one keeps its own daily limit.
A reply ends that person's sequence and lands in your inbox for you to answer.
LinkedIn, X, and email run as parallel lanes for the same buyer, so nobody gets the same pitch twice.
Requests sent
200 / week
New accounts start slow and ramp up over the first weeks, so the growth looks like a founder getting active, and doesn't get you blocked.
Your LinkedIn credentials are never saved anywhere in our system.

The short answers, before you connect anything.
The public YC company directory. Each founder's LinkedIn and X are the ones they listed on their own YC profile, so there is no guessing and nothing from Bookface. Email addresses are looked up and verified one by one before any email step runs.
Everything is sent from your own accounts inside each platform's limits: LinkedIn connection requests are capped per day and per week, X DMs are paced and only go to founders whose DMs are open, and every message is one you approved.
Yes, we use residential proxies near your location and use queueing and back-off warmup workflows to make sure every action looks natural and doesn't get blocked.
No. You approve the buyers and LinkedIn sequence before outreach starts.
Yes, but only when you are ready to run outreach. Setup happens inside your workspace.
Not when you create your workspace. A card is required when you start the live trial.
The live trial is 7 days and $0 today. A card is required when the trial starts. Then it is $75/month instead of the $99 list price. Extra users are $25/month. Cancel anytime.
If your first paid month books no qualified meeting, we return the first-month base fee. Read the guarantee terms.
PumpGTM sends from your own X, LinkedIn and email accounts, and hands you the replies.
