About

What is SellBigger

SellBigger runs AI-driven outbound across email, LinkedIn, InMail, voicemail drops, and phone — automating prospecting, enriching contact data, identifying decision-makers, and booking meetings without manual SDR intervention. It's built for SDR and BDR teams at mid-market and enterprise companies that need to scale pipeline without proportionally scaling headcount. The standout capability is its done-for-you AI SDR tier: one seat deploys eight AI profiles running 15,000 emails and 2,500 LinkedIn connections per quarter, with daily first-line responses and automated meeting booking included. No public API is available, so SellBigger can't be driven programmatically or wired into a broader agentic stack — what you see in the UI is what you get.

Our verdict

Vanderbuild take

SellBigger is a done-for-you multichannel outreach platform aimed squarely at SDR and BDR teams that want pipeline activity automated rather than just assisted — it's closer to an outsourced AI SDR service than a self-serve sequencer. On the agentic readiness front, there's no public API and no MCP server, so you can't drive this from an external agent or plug it into an orchestration layer — it's UI-only, full stop. Budget tier 3 is accurate: the Agentic AI Assistant starts at $1,250/month plus a $500 setup fee per AI SDR, so you'll want an operator who knows how to configure sequences and LinkedIn workflows to extract real value. No published case studies exist on the site, which makes it harder to benchmark expected outcomes before committing at that price point.
