Don't take our word for it
Resellers using Launch Cost in our beta program.
“I was spending 3 hours a day answering 'is this still available?' across four apps. Set up Launch Cost on a Sunday, haven't typed that reply since.”
Sarah C.
Full-time reseller, 600+ listings
“My average reply time went from 4 hours to under 10 seconds. Buyers actually started buying more because they got instant answers.”
Marcus R.
Sneaker reseller
“I set up 5 templates in maybe 10 minutes. Now I just check the dashboard once a day to see how many messages it handled. Usually around 30-40.”
Jessica P.
Vintage clothing, Poshmark + Mercari
“I have 200+ active listings across eBay and FBMP. Before this I was either ignoring messages or spending my whole evening replying. Neither was good for sales.”
David T.
Power seller, 4 platforms
“Honestly thought it would sound robotic but the template variables make every reply feel personal. Nobody's figured out it's automated yet.”
Aisha W.
Side hustle reseller
“The bundle offer template alone has probably made me an extra $200 this month. Buyers love getting a personalized discount before they even ask.”

Questions & answers
If yours isn't here, email us. We reply fast. (Manually, for now.)
Launch Cost uses smart pattern matching to identify common buyer questions — "is this available?", "what's your lowest?", shipping questions, etc. You choose which types get auto-replies and how sensitive the matching is.
No. Replies come from your actual account and use your templates with dynamic variables (buyer name, item title, price). They read like you typed them yourself.
We currently support eBay, Poshmark, Mercari, and Facebook Marketplace. More platforms are on the roadmap — join the waitlist and we'll let you know when they're live.
Yes. Each template can have platform-specific variations. Your Poshmark reply can differ from your eBay one, even for the same question type.
We use encrypted OAuth to connect your accounts. We never store your passwords. All data is encrypted in transit and at rest.
One click to pause globally or per platform. You can also set quiet hours so replies only go out during business hours.
