Every tool owns one tile. Sellton owns the lane.
Clay, Reply.io, HubSpot, and the rest are genuinely good at their one stage of go-to-market. Wire five or six of them together with an SDR or an agency and you get most of a lane. Sellton runs the whole thing as one autonomous system, in your own voice.
Outbound is a lane with eight stages: research, positioning, ICP, brand and LinkedIn voice, outbound, follow-up, pipeline, and execution. No single tool on this page runs more than a slice of it. Clay owns the data. Reply.io owns the sequence. Ava and AiSDR own the send. HubSpot owns the record. Airspeed sharpens the deals you already have. To cover the rest you add tools, a copywriter, a strategist, an SDR, and yourself as the integration layer. Sellton runs that lane as one system, with humans approving strategy and nothing falling through the cracks. Pay-per-use, no seats, no retainer, no lock-in.
Clay
Data, enrichment, researchThe best programmable data engine in outbound. It hands you an enriched, researched list. Positioning, your voice, sending, follow-up, and pipeline are still yours to build around it.
vs ClayReply.io
Multichannel sequencingOne of the stronger multichannel sequencers, with real deliverability tooling. But it sends the cadence you already wrote; the strategy, voice, data, and pipeline are a stack around it.
vs Reply.ioAva (Artisan AI)
Autonomous AI BDRA genuinely strong autonomous BDR that sources at scale, sends multichannel, handles replies, and books meetings. It owns outbound; positioning, your voice, and pipeline still sit on you.
vs AvaAiSDR
AI SDR outreach + repliesA sharp AI SDR that runs email and LinkedIn, handles objections, and books meetings, fast setup. It owns send-and-reply; the strategy that feeds it and the pipeline after are yours.
vs AiSDRHubSpot
CRM: storage, pipeline, sequencesThe best system of record and best in class at pipeline tracking. But a database is empty until something does the research, positioning, and writing that fill it.
vs HubSpotAirspeed
Downstream deal intelligenceA sharp revenue execution platform that reads call data to score deals, forecast, and coach reps. It sharpens the pipeline you already have. It does not create it.
vs AirspeedBuild it yourself
The glueTotal control and powerful point tools, but every tool owns one tile and none own the handoffs, so you become the integration layer. Glue is the first thing to crack on a busy week.
