Open Outreach > Investor campaign and check the causes below. Work down the list in order.

Give it a few hours, and check the day. Right after you launch, the first contacts take a few hours to move into Warming up. Each investor then gets about one day of warm-up before SeedForge sends the connection request and the card shows Reached out. Sending runs only 09:00 to 19:00 GMT, six days a week, Saturdays off, and ramps from 10 connection requests a day up to a maximum of 20. A quiet first day, or a silent Saturday, is normal. First results typically show in about one week.
Make sure it is launched or resumed. On Outreach > Investor campaign, look at the main control. If it reads Launch campaign, your campaign has not started, so click it. If you paused earlier, click Resume. While a campaign is paused, no new connection requests go out until you resume.
Approve at least one investor. Your campaign cannot start until at least one investor is approved. On Outreach > Investor campaign, open Queued and click Approve all, or approve investors one at a time.

Check your balance. After your free trial, your campaign pauses when your balance drops below $25, so an outcome always has budget. Open Billing, click Top up (a $50 minimum initial top-up, refundable anytime, no questions asked), then click Resume sending if the campaign is still paused.

Reconnect your LinkedIn if it dropped. If you changed your LinkedIn password, turned on two-factor authentication, or your sender disconnected, sending stops. Your campaign is saved. Open Outreach > Investor campaign to reconnect LinkedIn or connect a different sender.
Ask support if your contacts ran out. If SeedForge has reached every matched investor, the campaign has nothing left to send. Email support@seedforge.com, and the team can help; investor coverage is expanding all the time.
Note: If you work through this list and the campaign still will not run, email support@seedforge.com with your startup name and what you see on Outreach > Investor campaign.
Quick answers
Why is nothing happening right after I launch?
The first contacts take a few hours to reach Warming up, and each investor gets about one day of warm-up before the connection request. A quiet first day, or a Saturday with no sending, is normal.
Why did my campaign pause on its own?
It pauses when your balance drops below $25, so a booked call always has budget. Open Billing, click Top up, then click Resume sending.
My LinkedIn disconnected. Did I lose my campaign?
No. Your campaign is saved. Reconnect LinkedIn, or connect a different sender, from Outreach > Investor campaign.
