Arbolus vs G2

Arbolus is the customer-led alternative to G2. Where G2 is a software review site built on crowdsourced peer ratings and vendor profiles, Arbolus gives investors and consultants the proprietary Voice of the Customer: named, attributable buyer insights on the B2B tech companies you are diligencing, backed by structured spend and renewal data you can question and defend. Here is how Arbolus compares to G2, where each one fits, and why deal teams choose Arbolus when the decision moves capital.

Arbolus vs G2 at a glance

Both platforms help you understand how a software product is received by the people who use it. The difference is who is speaking, why they are speaking, and what you can do with the answer. G2 aggregates crowdsourced peer reviews and star ratings to help buyers compare tools, with much of the model funded by vendor marketing and lead generation. Arbolus is built around named, verified buyers and the structured spend, NPS and renewal data that commercial due diligence on B2B tech depends on.

For a quick sense of sentiment in a category, a peer rating is a reasonable starting point. For a decision that moves capital, you need to know who said it, what role they hold, how much they spend, and whether they are about to churn or expand. That is the gap Arbolus is built to close.

What is Arbolus?

Arbolus is a B2B customer-insights platform and modern expert network built for private equity, consulting and corporate strategy teams. Rather than aggregating anonymous ratings, Arbolus captures the Voice of the Customer directly: proprietary, attributable insight from the buyers and users of the software you are evaluating, across a library of more than 20,000 private tech companies.

That focus makes Arbolus a natural G2 alternative for anyone whose thesis hinges on product-market fit, retention and competitive moats, and who needs evidence that will hold up in an investment committee rather than a star rating. The platform pairs an always-on library with tools to collect fresh insight on demand, so you can start reading what customers think before your first call and go deeper only where it matters.

The Arbolus Library

The Arbolus Library lets you track companies and read verified customer insights with no project required. It is supported by company reports and a video insights library that keep updating as new buyer feedback arrives, which means the picture of a target evolves over time instead of being frozen at the moment a review was written.

Canopy video Q&A

With Canopy you send preset questions to a pool of relevant buyers and receive structured video or text answers within hours. You hear from several customers at once, compare their answers side by side, and decide which perspectives deserve a live follow-up, so you never wait days for a scheduled call just to ask a first question.

Calls, Surveys and Panels

When you need to go deeper, Calls handles screening, scheduling and AI transcripts, while Surveys and Panels reach your target sample quickly with fully attributable responses. All of it sits in the same workspace as the library, so evidence from different sources builds into one view of the company.

Why teams pick Arbolus

Named, attributable buyers rather than anonymous reviewers
Structured NPS, spend and renewal signals on a specific company
Fresh answers on demand, not ratings left at some point in the past
Built for investor and consultant diligence, not vendor marketing
One workspace for library, calls, async video Q&A and surveys

What is G2?

G2 is one of the largest software review sites in the world. It collects crowdsourced peer reviews and star ratings across thousands of products and publishes comparison grids that buyers use to shortlist tools. Much of the model is funded by vendor marketing and lead generation, with vendors paying to enhance their profiles and reach buyers who are actively comparing software.

For gauging broad sentiment in a category, that crowd is useful, and for a buyer choosing between well-known tools it can be a sensible first stop. But it was not designed to deliver the proprietary Voice of the Customer that B2B tech diligence relies on. Reviews are largely anonymous and self-selected, can be shaped by vendor review campaigns, coverage of a specific private company can be thin, and the ratings reflect a moment in the past rather than a buyer you can question today.

Where G2 falls short for customer diligence

Reviews are anonymous, so you cannot weigh who is speaking or how much they spend
Ratings are self-selected and can be shaped by vendor review campaigns
Coverage skews to tool comparison rather than investor-grade diligence
Much of the model is built for vendor marketing, not independent research
You cannot ask a follow-up question of an anonymous reviewer

Arbolus vs G2: the key differences

Named buyers vs anonymous reviews

G2 tells you what an anonymous crowd rated. Arbolus tells you what a named, verified buyer actually thinks, including their role, their company and their relationship with the product, so you can weigh the source, follow up, and cite the evidence.

Current data vs a static rating

A review is fixed at the moment it was written, and there is no way to know whether that customer is still a customer. Arbolus gives you current NPS, spend and renewal signals, and lets you commission fresh answers on demand when you need to test a specific hypothesis.

Diligence evidence vs shortlisting

G2 is built to help buyers compare and shortlist tools across a category. Arbolus is built to help investors and consultants reach a defensible conclusion on a specific company: how sticky it is, where it wins and loses, and what its customers plan to do at renewal.

Independent research vs vendor marketing

G2 ratings sit alongside a vendor-funded model, where the companies being reviewed are also customers of the platform. Arbolus insight is proprietary and attributable, collected for your diligence rather than for marketing, and the vendor has no role in shaping it.

Why choose Arbolus over G2

If your work depends on understanding customers, not skimming anonymous ratings, Arbolus is the stronger choice:

Attributable buyer evidence you can defend in an investment committee
Current spend and renewal signals on the specific company in front of you
Answers in hours through async video Q&A, calls and surveys
Deep coverage of private, mid-market B2B software in the $10M to $100M ARR range
A focused customer-insight platform, not a review site

Frequently asked questions

Is Arbolus a good G2 alternative?
Yes. Arbolus is a customer-led alternative to G2, built for investors and consultants who need named, attributable buyer evidence on B2B tech rather than anonymous peer ratings. It is not a replacement for a review site if you are a buyer shortlisting tools, but it is the better fit when you are evaluating a company rather than choosing a product.

What is the main difference between Arbolus and G2?
G2 aggregates crowdsourced peer reviews to help buyers shortlist software. Arbolus captures proprietary, attributable insight from named buyers, with structured spend and renewal data collected fresh on demand, and lets you follow up with those buyers directly.

Does Arbolus cover public and private companies?
Arbolus is built for B2B software, with its deepest coverage of private, mid-market companies in the $10M to $100M ARR range, where review coverage on sites like G2 tends to be thin or non-existent.

How quickly can I get answers?
Often straight away. Verified buyer insights can be read on demand in the library, and async video Q&A through Canopy returns answers within hours without waiting to schedule a live call. When a live conversation is needed, Calls handles the screening and scheduling for you.

How is pricing structured?
Arbolus is a platform subscription that includes the buyer-data library and the research toolkit, rather than a charge for every interaction. Book a demo and the team will walk you through the detail.
