The AI-native GTM system that finds your buyers, creates the campaigns and fills your calendar.
Business context stays distinct from people. Do-not-contact accounts are excluded before outreach. Eligible accounts enter the engine, messages feed a coordinated campaign, and an illustrative positive reply becomes a calendar booking.

We fill your calendar with high-intent, qualified leads. The results speak for themselves.
Over half of the meetings we book turn to closed-won

for our partners
We’re not a channel they’re testing. We’re driving the majority of their dealflow

The tech is genuinely impressive, but you also have access to some of the strongest GTM minds in the space. HappyStack is like an extension of our own team.
Our system maps your market, finds your perfect buyers, designs the creative, and runs synchronised multi-channel outbound.
Your team doesn’t write a single email. They focus on what matters most, closing deals.
Who they are. What they’ve posted. What their painpoints are. Why they’d book a meeting.
HappyStack’s AI learns what strategies, messaging, leads and channels work best, so results improve over time.
HappyStack folds every tool, data provider and channel into one system.
HappyStack plugs into your CRM, and the rest of the product runs itself.
Nobody else in the space can say the same.
It’s already booking meetings, just not yours. Drop us a message, and if you’re a fit you’ll hear back.
Two parts: a monthly platform fee, and a revenue share on what you close from the meetings we book. The fee covers the platform. The revenue share is how we get paid on what you close, so we only earn more when you do.
HappyStack runs the prospecting and outbound motion for your business: mapping your market, researching the right accounts and buyers, writing personalised outreach, and booking qualified meetings. Your sales team receives ready-to-close conversations instead of doing the prospecting work themselves.
Yes. Unlike other GTM tools, our system is built to run end-to-end. Your daily involvement is simply meeting with the leads we place in your calendar. There’s room to review your audience, review your sales angles and personalise material, but after the onboarding calls, our partners typically spend their time jumping on calls, not figuring out how to use another GTM stack.
Our data is the best in the industry. We use several waterfalls paired with agentic research flows to deeply understand every corner of your market. The reason our data is so strong is that we aren’t concerned with serving the entire world. Instead, we serve specific industries one by one until we’re confident we have a dataset we can sell to.
No. HappyStack handles market mapping, research, outreach, and meeting booking. Your team keeps ownership of the parts that need human judgement: relationships, sales conversations, negotiation, and closing.
Art is subjective.
