Haku vs Gojiberry: signal intelligence vs LinkedIn-only outreach.

Gojiberry is one of the most interesting new entrants in signal-based outbound — bootstrapped to $1M ARR in nine months, genuinely good at what it does, and honest about what it does not do. What it does not do is anything outside LinkedIn. Here is the comparison that matters.

Gojiberry deserves credit. Its founders — Pierre-Eliott Lallemant and Romàn Czerny — built it after selling CoCo AI to a US fund, used Gojiberry to sell Gojiberry, and hit $1M ARR in nine months without venture capital. They reported a 34% response rate at a customer acquisition cost of $127. That is not a typical story in the crowded outbound tooling market, and the numbers are worth taking seriously.

But the tool that works for selling Gojiberry to B2B SaaS sales teams on LinkedIn is not necessarily the tool that works for a UK manufacturing company trying to reach procurement directors, or a professional services firm selling into financial services, or any team whose buyers are not daily LinkedIn users. The comparison between Haku and Gojiberry is primarily a question of scope: LinkedIn signals versus all signals, single-channel outreach versus multi-channel, and what happens when your ICP does not live on LinkedIn.

What each product actually does

Where Gojiberry is the right choice

Gojiberry's core thesis is correct: outreach to prospects who are already showing buying intent converts better than outreach to a cold list. That is exactly the same thesis Haku is built on. The question is where you look for the signals.

If your buyers are active on LinkedIn — B2B SaaS founders, sales leaders, RevOps practitioners, marketing directors — Gojiberry's LinkedIn signal monitoring is genuinely effective. It watches for engagement with competitor content, recent job changes, event attendance, participation in relevant groups, and profile activity that suggests an active evaluation. These are real signals, and automating outreach to prospects showing them is a materially better approach than blasting a static export.

At $99 per month for unlimited campaigns and 30+ intent signals, Gojiberry is well-priced for solo founders and small teams whose entire outbound motion runs through LinkedIn. If that describes your team, Gojiberry is worth evaluating seriously.

Where Gojiberry hits its ceiling

The ceiling appears in three places — and all three matter for teams trying to build a serious outbound programme.

Signal scope. Gojiberry monitors what happens on LinkedIn. It does not know that a company raised a Series A last week, or that a new VP of Sales just joined, or that a target account just posted twelve new SDR roles, or that they just migrated their CRM from Salesforce to HubSpot. These are some of the strongest buying signals in B2B outbound — and none of them require LinkedIn activity to detect. A company that just raised funding and has not posted anything on LinkedIn yet is still in a buying window. Gojiberry will not surface it.

Channel scope. Gojiberry is a LinkedIn outreach tool. It sends connection requests and DMs. It does not send emails, make calls, or coordinate multi-channel sequences. For teams whose outbound motion includes email — which is most teams, given that LinkedIn DMs cap at connection acceptance rates of 15 to 30% — Gojiberry is one part of the workflow rather than the whole thing. The 2-sender cap on the Pro plan also constrains volume: two LinkedIn accounts at safe sending limits of 20 to 30 connection requests per day produces 40 to 60 outreach attempts per day maximum.

Coverage scope. LinkedIn signals work best when your buyers are daily LinkedIn users. B2B SaaS, sales technology, marketing, and recruitment are strong. Manufacturing, construction, logistics, professional services, financial services, and most EMEA markets outside London and major tech hubs are significantly weaker. Gojiberry's co-founders built it for a market — B2B SaaS founders and sales leaders — where LinkedIn is the dominant professional channel. That market is real and large. It is not all of B2B outbound.

“Gojiberry is a great tool for the specific market its founders built it in. The question is whether your buyers behave the way Gojiberry's buyers behave on LinkedIn — and for most B2B outbound teams, the honest answer is: some of them do, and some of them do not.”

Head to head — feature by feature

Which team should choose which

Can you use both?

Yes — with clear role separation. Gojiberry handles LinkedIn outreach to prospects showing LinkedIn-native intent signals. Haku handles the broader intelligence layer: surfacing accounts from funding events, leadership hires, and technology changes that Gojiberry will never detect, and providing the verified contact data for the email and phone outreach that sits alongside the LinkedIn motion.

In practice, most teams evaluating both tools are choosing a direction: LinkedIn-first with Gojiberry, or signal-intelligence-first with Haku feeding a multi-channel stack. The teams doing serious outbound volume with mixed channels and mixed buyer profiles will typically find Haku provides more of the infrastructure they need. The teams running a focused LinkedIn motion to a well-defined LinkedIn-active ICP will find Gojiberry faster to set up and more purpose-built for that specific job.
