Re: scaling before the first sales hire.
Hey Priya, saw your team just brought on your first AE. That moment right before the hire, when the founders are still running every call, is exactly what Warmline was built for.
EARLY ACCESS OPEN
Cold email is stale.
Send Warmlines.
You know who to reach. You just don't have 18 hours to research and write 20 messages this week.
No subscription. Pay per engagement when you are ready.
18–48 hrs
spent per week on outreach research and writing
< 3%
average cold email reply rate when using templates
0 tools
built specifically for founders doing their own selling
Based on founder surveys and industry benchmarks.
You already know this pain.
Warmline is built for the person doing the selling, not a sales team.
01
Hours lost before you write a single word
Researching the company, finding who to contact, checking LinkedIn, reading their site. All before you've opened a blank message.
02
Messages that sound like everyone else's
Templates are obvious. Buyers delete them. The ones that work are personal. Writing personal at scale is what breaks founders.
03
No memory of what you've done
You reach out, you forget who you emailed, you send a duplicate, or you never follow up. Outreach becomes a black hole.
THE PROCESS
Three steps. One briefing. Twenty messages.
- 01
Feed it your context
Upload a pitch deck, paste your Notion brief, or fill out a short form. You do this once. Warmline learns your voice, your product, and what makes you different.
- 02
It researches your targets
Point it at a list of companies or let it suggest. It searches LinkedIn profiles, company websites, funding databases, and public business signals to find the right person to contact and surface what angle will actually resonate. No generic ICP logic.
- 03
Review 20 messages. Send what feels right.
Every message is shaped by your voice and something specific about the person. You read them, edit if you want, and decide what goes out. Nothing sends without your approval.
STEP 1 — YOUR BRIEF
📎 Business contextpitch-deck.pdf×linkedin-profile×
We're building Warmline, an outreach drafting tool for early-stage B2B founders. Our customers are early-stage founders and small founding teams doing their own outreach before their first sales hire. We help them go from a list of target companies to 20 personalized, research-backed messages in under 4 hours, without any of it sounding like a template. Our differentiator: the messages sound like the founder wrote them because we train them on their voice, their pitch, and their specific goals. Nothing sends without their review.
STEP 2 — TARGET RESEARCH

Hey Daniel, noticed your comment about cold email not working for early pipeline. Warmline is a drafting tool, not a sender. You feed it your context once, and it writes outreach that sounds like you.

FOUNDER CONVERSATIONS
What founders told us before we built anything.
We did not start with a product. We started with conversations. These are the signals we heard.

0.2% interest rate. That is the world Warmline is built to replace.
One founder DMed us privately from Kenya after seeing this described in a thread. That was the signal we needed.
THE REAL DIFFERENCE
Built for the founder doing the selling. Not the sales team.
Other tools are built for volume and automation. Warmline is built for the person who needs to sound like a person.

What you feed it
Target persona and signals
Your pitch deck, Notion, meeting notes
We are not a replacement for a sales team. We are for founders who do not have one yet.
It sounds like you. Not like a tool.
Every message is grounded in your voice, your pitch, and something real about the person you're reaching. You stay in control. Nothing sends without your review.
Built for founders
Not sales teams. Not growth hackers. The person doing the work before the first sales hire.
Review before send
Warmline is not an auto-sender. It is a drafting engine. You stay in the loop on every message.
Warmline is not for everyone.
- –You want to send 500 messages a week without reading them.
- –You need a full CRM and pipeline management system.
- –You already have a sales hire doing this for you.
If any of those describe you, Apollo or Gojiberry will serve you better. Warmline is for the founder in the room before any of that exists.

We're working with a small group of founders first. Drop your email, and we'll reach out.
No spam. No pitch sequences. Just a message when we're ready for you.
