AI SDR alternatives: what to use instead

An AI SDR tool finds prospects, writes outreach, and sends it with little or no rep involvement. An AI SDR alternative is a custom signal-driven system your team owns. OneGTM builds that system for seed to Series C teams with Clay, Claude Code, and Attio. Garrett Wolfe, an early Unify employee (#9) who helped grow Unify's ARR from $400K to $6M+, leads the work.

What an AI SDR tool is

An AI SDR tool is software that finds prospects, writes outreach, and sends it with little or no rep involvement. Teams look at one when they want outbound running without hiring SDRs. The product covers research, list building, writing, and sending in one place.

This page stays with that category. It does not review individual vendors or repeat claims from their sites. For vendor-published pricing and features, see AI SDR tools.

What to use instead

Use a custom signal-driven system. OneGTM builds that for seed to Series C teams: outbound, signals, CRM, and AI, with Clay, Claude Code, and Attio. Garrett Wolfe, Unify employee #9, leads the work. OneGTM is a Clay Artisan Solutions Partner and an OutboundSync Agency Partner.

The published results are Antimetal, $2.57M in pipeline from 17 automated outbound deals, and Coastal Recruiting, 4.7x more accepted intros. Green Dock Partners gets a daily digest of industrial site closures, and that case study claims no deal outcome.

The same practice, written as a service page, is the GTM engineering agency page. Outbound specifically is the signal-based outbound agency page, and the Clay slice is the Clay agency page.
