Best Analytics Tools for B2B SaaS in 2026

Consumer app analytics is about virality loops, retention D7/D30, and daily active users. B2B SaaS analytics is about something else entirely: which companies activated, which trials are going cold, which accounts are primed for an expansion conversation, and where exactly your onboarding funnel loses the decision-maker. Pageviews won't tell you any of that.

The tools that dominate the general-purpose analytics conversation — GA4, Plausible, even standard PostHog setups — were built around individual user behaviour. B2B has a fundamental unit mismatch: you sell to companies, but most analytics track people. An account where five people are active looks identical to five single-user accounts if you're not thinking at the company level. Seat expansion, trial conversion, and churn all operate at the account level. Your analytics stack needs to as well.

This list covers the seven tools that B2B SaaS founders actually reach for in 2026, with an honest account of what each one does well and where it falls short.

Quick answer: PostHog with Group Analytics enabled is the most flexible starting point for B2B founders who want both user-level and account-level data without a second tool — but if your product is past early-stage and you need pre-built B2B metrics out of the box, June is purpose-built for exactly this and saves weeks of configuration.

PostHog

PostHog has become the default product analytics recommendation for a reason: the free tier is genuinely generous (one million events per month), it ships session replay, feature flags, and A/B testing alongside analytics, and it is self-hostable if data residency matters to your enterprise buyers. The feature that makes it relevant specifically for B2B is Group Analytics — the ability to associate events with a company entity rather than just a user. Once you set up groups, you can answer questions like "what percentage of accounts that signed up this month completed at least three sessions in week one?" rather than just counting individual users. The setup requires some deliberate event design upfront: you need to call posthog.group('company', companyId, { name, plan, seats }) at sign-in, and make sure that context is attached to every event. It is not plug-and-play, but the payoff is a full B2B analytics setup inside a single platform. Pricing stays free until you exceed a million events monthly, then scales incrementally. Limitation: the B2B-specific reports you'd want — account health scores, expansion signals, account list views — need to be built manually using PostHog's funnel and retention tools. There is no pre-built "trial-to-paid" dashboard waiting for you.

Mixpanel

Mixpanel is arguably the best pure funnel and retention analysis tool available in 2026 for B2B products. Its cohort analysis is precise, the funnel builder handles complex multi-step conversion paths cleanly, and the retention charts give you genuinely actionable cohort data. The free tier covers 20 million events per month, which is enough for most B2B SaaS products through early growth. For B2B specifically, Mixpanel's Group Analytics feature (available on paid plans) adds account-level reporting in a similar way to PostHog. Where Mixpanel earns its place over PostHog is in the depth and flexibility of its query interface — if you want to ask precise questions about funnel drop-off segmented by company size and plan type, Mixpanel handles that more fluently. The honest tradeoff: Mixpanel rewards founders who design their event taxonomy carefully before instrumenting. Fire events ad hoc and your reports become noise. Spend a half-day designing your event model — account created, trial started, key action completed, invite sent, upgrade initiated — and Mixpanel becomes one of the most powerful tools in your stack. Pricing for Group Analytics starts on the Growth plan. Limitation: no session replay, no feature flags, no built-in data warehouse — you are paying for analytics depth only.

Amplitude

Amplitude sits at the enterprise end of the product analytics spectrum. The Starter plan covers ten million events per month and includes funnels, retention, and user segmentation — enough for a well-instrumented B2B product through early growth. The platform is genuinely well-designed: the interface is cleaner than Mixpanel for stakeholder-facing reporting, and the chart types cover almost every analysis a product team would need. For B2B SaaS, Amplitude's Accounts feature (available on paid plans) handles company-level analytics properly. Where Amplitude distinguishes itself from alternatives is in predictive analytics and behavioral cohorting at scale — features that require the data volume and team bandwidth to act on them. The realistic concern for an early-stage B2B founder: the paid tiers that unlock the genuinely differentiating features start around $995/month. If you have a growth team and the revenue to support that spend, Amplitude is excellent. If you're a two-person team with 200 trial accounts, the free Starter tier will serve you, but the ceiling arrives quickly. Limitation: pricing jumps steeply once you need enterprise features; the free tier is a useful starting point but not a long-term home for a growing B2B product.

Heap

Heap's defining feature is autocapture — it records every click, tap, form interaction, and page view automatically, without requiring you to manually instrument individual events. For B2B founders, this has a specific advantage: you can go back retroactively and build funnels around actions you didn't know you'd want to track. Most analytics tools require you to add an event before you can analyse it; Heap means you can ask questions about user behaviour from before you thought to ask them. In practice, autocapture generates a lot of noise alongside the signal — Heap's data model requires work to organise captured events into meaningful actions. But for B2B onboarding analysis specifically, the ability to audit every step of your trial activation flow without adding tracking code is genuinely valuable. Heap also has account-level analytics built in, handled through its "Accounts" concept. Pricing is custom for most plans; there is a free tier for up to 10,000 sessions per month. Limitation: autocapture creates data volume and organisation overhead; the free tier is limited and enterprise pricing requires a conversation. Better suited to teams with a dedicated analyst than to solo founders.

June

June is purpose-built for B2B SaaS analytics. While PostHog and Mixpanel require you to configure account-level tracking manually, June ships with it as the default — every report, every metric, every alert is designed around companies, not users. Out of the box you get: activation funnel by company, weekly active companies, account health scores, trial-to-paid conversion rate, and Slack alerts when a key account goes quiet. June sits on top of Segment or accepts events directly via SDK. If you already have a Segment pipeline, June is almost zero-configuration for the analytics layer. The pre-built report library covers the metrics that B2B founders actually care about — it is genuinely faster to get to insight than any general-purpose analytics tool configured for B2B. Pricing: a free tier exists for early-stage products; paid plans start at $149/month as you scale. Limitation: June is deliberately narrower in scope than PostHog or Mixpanel — it does not ship session replay, feature flags, or A/B testing. It is an analytics layer, not a full product platform. If you need session replay alongside your B2B metrics you will need a second tool.

Chartmogul

Chartmogul is revenue analytics, not product analytics — it belongs in a different category from the tools above, but it is indispensable for B2B SaaS and often overlooked in analytics stack discussions. It connects to Stripe, Paddle, Chargebee, or Recurly and surfaces your MRR, ARR, churn rate, net revenue retention, LTV, and plan mix in real time. For a B2B founder managing a trial-to-paid conversion funnel, Chartmogul tells you what actually converted, what churned, and what expanded — data that product analytics tools do not surface cleanly because they don't have access to billing events. The free plan covers up to $10K MRR, which is a genuine free tier for early-stage products. As revenue grows, paid plans start at $199/month. Chartmogul pairs naturally with June or PostHog: one tells you what users are doing in the product, the other tells you what those behaviours mean in revenue terms. Limitation: Chartmogul is a revenue analytics tool, not a behavioural analytics tool — it cannot tell you why accounts churn, only that they did and when. It needs a product analytics partner to complete the picture.

Baremetrics

Baremetrics is the direct alternative to Chartmogul and worth knowing about if you're on Stripe. It connects to Stripe natively and surfaces MRR, ARR, churn, LTV, and cash flow forecasting in a clean dashboard. The Recover feature — automated failed payment recovery via smart dunning — is a meaningful add-on for a B2B SaaS with annual contracts, where a failed card payment might otherwise cause involuntary churn that takes weeks to notice. Baremetrics also ships "Benchmarks," an anonymised view of revenue metrics across the other Baremetrics customers in your cohort, which gives you a sense of whether your churn or LTV numbers are normal for your segment. Pricing starts at $108/month for up to $10K MRR. The honest comparison to Chartmogul: both tools are strong; Baremetrics has a slightly simpler UX and the Recover feature is differentiated; Chartmogul has more flexibility in connecting multiple payment processors and a more robust segmentation model. If you are Stripe-only and want the simplest possible revenue dashboard with dunning, Baremetrics is the easier choice. Limitation: like Chartmogul, Baremetrics is a revenue analytics layer — it does not replace behavioural product analytics.

The right stack for B2B SaaS founders

Stage	Recommended stack
Pre-launch to 50 accounts	PostHog free (Group Analytics enabled) + Chartmogul free
50–500 accounts	June ($149/mo) + Chartmogul free, or PostHog free + Mixpanel Growth
500+ accounts with growth team	Amplitude Growth + Chartmogul/Baremetrics paid

The most common mistake is treating B2B SaaS analytics like consumer analytics and skipping the account-level setup. Configure group/company entities from day one — retrofitting it later requires replaying all your historical events.

Frequently Asked Questions

Do I need separate tools for product analytics and revenue analytics?

Yes, for most B2B SaaS products. Product analytics tools (PostHog, June, Mixpanel) track what users do. Revenue analytics tools (Chartmogul, Baremetrics) track what that behaviour means in subscription revenue. Neither does the other's job well. A combined stack of one product tool plus one revenue tool is the standard setup.

What's the difference between user-level and account-level analytics?

User-level analytics tracks individual people. Account-level analytics aggregates those people into company entities. For B2B, you care about questions like "did Acme Corp complete onboarding?" not just "did a user complete onboarding?" — because you sell and renew at the account level. PostHog Group Analytics, June, and Mixpanel Accounts all support account-level tracking.

Is PostHog's free tier genuinely usable for a B2B product?

Yes, up to one million events per month. Most B2B SaaS products with under a few hundred active accounts will stay within that limit comfortably. The catch is that Group Analytics configuration requires upfront work — it is not automatic. Budget a half-day to design your event model and set up company groups before you launch.

When does June make more sense than PostHog?

When you want B2B metrics out of the box without spending time on configuration. June's pre-built reports for activation, retention, and account health take hours to set up versus the days it takes to build equivalent views in PostHog. If you're already Segment-instrumented, June is close to zero configuration. If you're starting fresh and want one platform that also handles session replay and feature flags, PostHog is more flexible.

Does Chartmogul or Baremetrics work with payment processors other than Stripe?

Chartmogul supports Stripe, Paddle, Chargebee, Recurly, Braintree, and others via a data import API. Baremetrics is primarily Stripe-focused. If you use Paddle or are selling in Europe with a merchant of record, Chartmogul is the safer choice.
