Top 8 HubSpot Alternatives for B2B SaaS in 2026

1. SaaSHero: Best Overall Agency-Led Alternative

Best for: Revenue-aligned B2B SaaS growth without lock-ins or percentage-based fees.

SaaSHero acts as an extension of your marketing team instead of a traditional software vendor. With $30M+ in managed ad spend and case studies like TripMaster’s $504,758 Net New ARR gain, SaaSHero delivers flat-rate retainers starting at $1,250 per month. Their competitor conquesting strategies and month-to-month agreements remove the risk of long contracts and keep focus on CAC, LTV, and payback periods.

The team’s specialized approach covers landing page conversion improvements, CRM integration setup, and senior-led account management with a maximum of 8–10 clients per lead strategist. Unlike percentage-based agencies that earn more when you spend more, SaaSHero’s flat-fee model keeps incentives aligned with your revenue growth.

2. ActiveCampaign: Automation Power at Lower Cost

Best for: Complex B2B sales funnels that need sophisticated automation at reasonable pricing.

ActiveCampaign starts at $15/month for up to 1,000 contacts, which is far more affordable than HubSpot’s $890/month Professional tier. The platform excels in behavioral automation with a drag-and-drop workflow builder and advanced segmentation. Plus plans start at $49 monthly, so it scales well for growing SaaS teams.

ActiveCampaign’s main strength comes from its flexible automation logic and broad CRM integration options. It usually requires more technical setup than HubSpot’s all-in-one model, but it rewards that effort with deeper control.

3. Pardot: Salesforce-Native ABM for Enterprise SaaS

Best for: Salesforce-native B2B marketing with enterprise-grade ABM.

Pardot delivers tight Salesforce integration for teams already committed to the Salesforce stack. Companies moving from HubSpot to Salesforce report over 31% revenue growth and 29% ROI improvement. Pardot supports sophisticated lead scoring, progressive profiling, and account-based marketing built for complex B2B sales motions.

Pardot requires more technical expertise and Salesforce licensing, yet it provides strong data sync and reporting for enterprise SaaS companies that need reliable, unified reporting.

Book a discovery call to see how SaaSHero can improve your Pardot setup or manage a full migration.

4. Marketo Engage: Advanced Attribution for Long Cycles

Best for: Enterprise B2B SaaS that needs advanced attribution and revenue cycle analytics.

Marketo regularly appears in Gartner’s Magic Quadrant leaders category for marketing automation. The platform offers multi-touch attribution, advanced lead lifecycle management, and powerful segmentation. Marketo’s enterprise pricing scales with workflow complexity instead of simple contact counts, which suits high-volume SaaS operations.

Marketo’s Revenue Cycle Analytics gives detailed pipeline visibility and attribution modeling. This level of insight supports SaaS companies that manage long sales cycles with many touchpoints.

5. 6sense: AI Intent Data and Dark Funnel Insights

Best for: AI-powered ABM and dark funnel visibility for enterprise B2B SaaS.

6sense focuses on account-based marketing with AI-driven intent data and predictive analytics. The platform identifies anonymous visitors and tracks buying signals across the dark funnel, so you see which accounts research solutions before they raise a hand. AI-driven predictive analytics forecast intent using historical and real-time data for custom segmentation, which supports stronger lead nurturing than rule-based systems.

6sense Revenue AI runs personalized campaigns across channels and automatically adjusts messaging and timing based on account behavior patterns.

6. Brevo: Low-Cost Multi-Channel Automation

Best for: Budget-conscious startups that need multi-channel automation.

Brevo starts at $9/month and includes AI campaign building and light CRM features. The platform offers simple CRM tools and multi-channel automation at a startup-friendly price, though it lacks deep CRM capabilities and heavy customization.

Brevo covers core email marketing, SMS, and basic automation workflows. Early-stage SaaS teams with tight budgets can use it as a practical starting point.

7. Act-On: Mid-Market Alignment for Marketing and Sales

Best for: Mid-market B2B SaaS that needs tight marketing and sales alignment.

Act-On delivers full marketing automation with strong lead nurturing and sales enablement tools. The platform includes advanced lead scoring, progressive profiling, and detailed campaign attribution reports. Its pricing scales with features instead of contacts, which helps growing SaaS companies control costs as databases expand.

Act-On integrates with major CRM systems and offers robust reporting to connect marketing activity with pipeline and revenue.

8. Klaviyo: Event-Based Automation for PLG SaaS

Best for: Product-led growth SaaS with heavy email and behavioral automation needs.

Klaviyo started in e-commerce and now supports B2B use cases with advanced behavioral tracking and personalization. AI enables real-time personalization and adapts email timing based on behavior and intent, which fits product-led growth models with frequent in-app activity.

Klaviyo shines in event-based automation and detailed lifecycle tracking. It usually requires a separate CRM integration to deliver full B2B functionality.

2026 Migration Strategy for Moving Off HubSpot

The 2026 Gartner Magic Quadrant places Marketo and Pardot in the leaders category, while AI-first platforms like 6sense gain recognition for innovation. AI marketing automation now outperforms static if-then rules by using machine learning for autonomous campaign prediction and improvement, which creates a clear edge over traditional rule-based tools.

Frequently Asked Questions About HubSpot Alternatives

Best Free HubSpot Alternative for B2B SaaS Startups

Brevo offers the strongest free alternative with basic CRM, email automation, and multi-channel support. Pairing Brevo with SaaSHero’s agency expertise adds professional campaign strategy and management that free tools alone cannot match. This combination delivers enterprise-level outcomes at startup-friendly pricing.

Why Salesforce Users Usually Choose Pardot Over HubSpot

With expert campaign management, companies often see 30–60% CAC improvements within 90 days of switching.

Affordable ABM Platforms Under $1,000 per Month

ActiveCampaign Professional at $49 per user each month delivers strong ABM through behavioral automation and advanced segmentation. For a more complete ABM approach under $1,000, many teams combine ActiveCampaign with SaaSHero’s competitor conquesting strategies to reach enterprise-level account targeting at mid-market pricing.
