TL;DR

• Gojiberry, OXYGEN and Deepline sell three different things. Gojiberry AI is a finished AI SDR (USD 99 per month, PRO plan). OXYGEN is an agent-native GTM workspace on credits (plans from USD 49 per month). Deepline is a pay-as-you-go data layer for coding agents (USD 0 per month plus usage, Growth USD 395 per month).
• LinkedIn is where they differ most. Gojiberry runs LinkedIn campaign steps itself. OXYGEN runs native LinkedIn actions on a connected account, which reserves 3,400 credits ($34) a month. Deepline reads LinkedIn through third-party catalog modules and sends through your own HeyReach.
• For developers, Deepline ships an MIT CLI and SDK package, a public OpenAPI with 12 paths and a remote MCP. Gojiberry's public API has 40+ operations, all on its own objects. OXYGEN is CLI and MCP first, and I found no public OpenAPI document.
• Pick by what you want to own. Gojiberry sells the outcome, OXYGEN the GTM workspace, Deepline the code.
• If your own agent should act on LinkedIn directly, Curviate, a LinkedIn API, CLI, MCP server and TypeScript SDK for AI agents (EUR 20 per account per month, excl. VAT), sits next to any of them.

"AI SDR" and "agent-native GTM" get used for very different products. Gojiberry, OXYGEN and Deepline all put AI on your go-to-market, and all three expose an MCP server. What you buy differs: an agent that does the work for you, a workspace your agent works in, or a data layer your agent calls from code. I build Curviate, a LinkedIn API for agents, and I compared the three from their public pages on October 2, 2026.

What are the three ways to put AI on GTM?

There are three: a finished AI SDR app (Gojiberry), an agent-native GTM workspace (OXYGEN) and a data layer for coding agents (Deepline).

With an AI SDR app, you describe your business and the vendor's agent finds leads and contacts them. Gojiberry's homepage promises an AI agent that finds high-intent leads and contacts them for you. The logic lives in their product, and you steer it.

An agent-native GTM workspace is one hosted system that holds your tables, sequences, CRM and senders. Your agent (Claude Code, Codex, any MCP client) operates it through a CLI or MCP. OXYGEN describes itself as "the agent-native GTM stack. The CLI and a real, governed MCP are the primary surface."

A data layer has no campaign UI and no inbox. Your agent calls enrichment, search and CRM tools from code, and the workflows live in your repo. Deepline calls itself "the agent-callable GTM data layer for enrichment, validation, CRM updates, audience sync, and sequencer pushes."

The last two are built for agents. In the first, the vendor's agent does the thinking, and yours can only give it orders.

How do Gojiberry, OXYGEN and Deepline compare?

They differ most in pricing unit and LinkedIn depth. Gojiberry prices by plan, OXYGEN by credits, Deepline by usage. Of the three, only OXYGEN runs native LinkedIn actions on a connected account at a published per-account price. Every cell comes from the vendor's public pages. "Not found" means I did not find it on the pages I checked.

Should you choose Gojiberry, OXYGEN or Deepline?

Gojiberry suits a founder or a small sales team that wants pipeline without building anything. One public price buys signal-based lead sourcing, AI-written LinkedIn and email sequences and a unified inbox. Its MCP server ("Muse") lets Claude or ChatGPT query and drive your Gojiberry workspace.

OXYGEN is for a team that wants one governed system for the whole motion: market data, waterfall enrichment, email and LinkedIn sequencing and CRM, with approval gates and spend caps. You run it from Claude Code or its own Workspace Agent. LinkedIn accounts are priced at 3,400 credits a month each.

Deepline is the pick for a GTM engineer who wants enrichment and data plays as editable TypeScript in their own repo, pays per call with no seat fee, and needs SOC 2 Type 2 for procurement. LinkedIn is a side channel there, so plan it separately.

If what you want is an agent that runs LinkedIn itself (search, profiles, messages, comments, Sales Navigator, Recruiter), that is a LinkedIn API like Curviate. It covers LinkedIn and runs next to whatever handles your data and email.

What is Gojiberry AI, and what does it do?

Gojiberry is a finished AI SDR. You enter your website, it learns your ICP and sources warm leads from what its FAQ lists as signals: engagement with your company or content, profile visits, competitor engagement, job changes, hiring and lookalikes. Then it runs outreach across LinkedIn and email. The PRO plan is $99/month and includes, in their words, "2 AI agents prospecting 24/7" and "Up to 1,800 prospects contacted/month".

For builders, the public API (40+ operations, 100 requests per minute per key) and the hosted MCP server expose Gojiberry's own objects: contacts, lists, campaigns and the unified inbox. Campaigns take seven step types, six on LinkedIn (invitation, invitation with note, message, voice message, profile visit, liking the prospect's posts) plus email. A separate inbox endpoint sends a LinkedIn reply in an existing thread. I found no commenting, InMail, post publishing or on-demand profile reads in the API. Your agent drives Gojiberry, and Gojiberry drives LinkedIn.

Gojiberry says it is "Backed by Y Combinator" and trusted by "2,000+ sales & GTM teams"; both claims are its own. The company behind it is SUPERFRUITS SAS in Paris.

What is OXYGEN, and how does it run LinkedIn?

OXYGEN is a workspace your agent works in. Its docs describe "a five-layer stack (Control, Knowledge, Data, Action, External) with fifteen product primitives", among them Tables, Sequences, Signals, Workflows and Agents. You drive it with the @oxygen-agent/cli npm package, a hosted MCP server, or the web app.

LinkedIn is native. A connected account can send invites, messages and InMail, comment, react, follow and post, and the docs export names 75 linkedin.* operations. On the pricing page, each connected account reserves 3,400 credits ($34) a month with every action included. The page also still shows a "LinkedIn account $30/mo" dollar seat, which its FAQ says runs until renewal and then switches to credits. Default send caps are 20 invites per account per day, maximum 30.

On account safety, its LinkedIn sequencer page says "Caps, ramps, and spacing reduce the risk of a restriction; nothing removes it".

The CLI package is UNLICENSED, and I found no public OpenAPI document and no general client SDK. Plans step from $49 to $1,999 per month, and a year costs ten months. The company is OXYGEN GTM Inc., a Delaware corporation.

What does Deepline do, and where is LinkedIn in it?

Deepline is a data and execution layer: one API key over 109+ integrations, waterfall enrichment and TypeScript "Plays". You reach it through the deepline CLI and TypeScript SDK (an MIT package on npm), a REST API with a public OpenAPI document, a remote MCP server, and an open Claude Code skills repo.

Pricing is usage-based. Pay as you go has no platform fee. Growth is $395/month and includes $200 of usage credits. Credits cost $0.10 each on Pay as you go and Growth; Enterprise is contracted. With your own provider keys, "Deepline does not mark up the provider's charge"; on Pay as you go that covers 50K calls a month, then $0.005 per call. There is no per-seat fee. Its security page states SOC 2 Type 2.

LinkedIn arrives through third-party provider modules in its catalog: profile, company, post and search reads, plus Sales Navigator and Recruiter Lite search tools. To send, you go through your own sequencer; the HeyReach module includes heyreach_send_message. I found no native Deepline LinkedIn account connection and no LinkedIn account-safety statement on the pages I checked.

How much does Gojiberry AI cost next to OXYGEN and Deepline?

Gojiberry costs $99/month on its PRO plan. OXYGEN plans run from $49 to $1,999 per month in credits. Deepline starts at $0 per month plus usage, with Growth at $395/month. The units differ, so compare the shape before the number. Prices are in USD unless noted, on monthly billing, and I did not convert currencies.

Gojiberry is one bill that includes the agent's work. Deepline gets cheaper the more you bring yourself, and OXYGEN does too from the $99 plan. Curviate has no base fee: you pay per LinkedIn account, excl. VAT.

Where does a LinkedIn action layer fit next to these three?

Curviate sits next to any of them, because all three treat LinkedIn as one channel inside a larger product, in a shape that product chose. Gojiberry's agent works through six LinkedIn step types and inbox replies. Deepline sends through your HeyReach campaigns. OXYGEN's native actions live inside OXYGEN's workspace and its pricing.

Curviate covers LinkedIn on your own account, as a REST API, a CLI, a hosted MCP server and a TypeScript SDK on one key. Each account gets its own limits and new accounts get a warm-up (safety). Your agent decides what to do on LinkedIn, and no vendor's sequence sits in between. A repeat profile read within 12 hours (the default) comes from your workspace's own store, with no LinkedIn request and nothing taken from the account's action budget (caching guide).

An agent can load more than one MCP server. Claude Code can run Curviate next to Deepline's enrichment or OXYGEN's tables in the same session:
