Your funnel, your CRM, your agents, in one view.

Ads, analytics, CRM, email.
Now agents run them as one stack.
Each tool is dragged in by an agent we run for you. You watch the funnel, we watch the funnel close.
Two crafts. One team.
onestack is run by engineers who built the systems you trust and marketers who scaled the brands you’ve heard of. The funnel works because both halves do.
Tech
Built by people who shipped the infra you trust
Nothing your agents do is a black box. Read the ledger, cap the budget, revoke a key, all from one dashboard. When finance asks, you already have the answer.
Bring your own database, your own domain, your own model provider. Nothing is trapped inside the platform. Export the schema in one command and walk away with everything.
Agents draft, you approve. Every outbound email, every posted page, every purchase order clears a person before it goes live. The audit trail records who said yes and when.
Claude, GPT, Gemini, or local — one line switches provider per agent. When a better model lands next quarter, you don't rewrite anything.
Marketing
Run by people who scaled the brands you know
Across 30+ engagements. Not a single one without a fully attributed funnel by week six.
In-house design and dev on the same team as the campaign. No agency ping-pong, no Jira tickets, no waiting for the next sprint. New idea Monday, live Tuesday.
You get us in the group chat where the rest of your team already lives. Weekly reports die in inboxes; a quick reply in the thread doesn't.
One team owns the ad, the landing page, the nurture, and the retention email. Nothing gets lost between agencies because there aren't any.
Marketing that fills the funnel.
We run the campaigns, ship the landing pages, and pipe every visit, click, and form straight into your CRM. One team owns traffic, attribution, and the handoff, so the funnel never breaks between the ad and the conversation.
- Campaigns, landing pages, and SEO managed end-to-end
- Every visit and lead attributed back to its source
- Built-in A/B routing, experiments, and conversion tracking
A CRM that catches every lead the marketing earns.
Every form, every email, every call, captured, enriched, and routed against the campaign that produced it. No more lead-list spreadsheets, no more "who's following up on this?", onestack already did.
- Inbound from your campaigns, attributed to the source
- Enrichment from 40+ public sources
- Auto-routing by industry, size, intent
The end of the shared-drive graveyard.
Brand assets, contracts, decks, product photos, searchable by what's inside them, not just the filename. Every file has version history, sharing controls, and an audit trail you can hand to legal.
- Visual + semantic search across files
- Version history with one-click rollback
- Granular sharing, expiring links, watermarks
Agents that earn their seat.
Pre-built agents for inbox, CRM, scheduling, and content, connected to the rest of your stack out of the box. Approve, edit, or auto-run. Every action is logged. Every cost is shown.
- 20+ ready-to-deploy agents
- Bring your own model, gateway included
- Full transparency: see every action, every token
