Digital analytics platform that helps teams build better products.

Founded: 2012 HQ: San Francisco Team: 700-1,000 Funding: $336M+ raised, publicly traded (AMPL)

Ideal for: Enterprise B2B SaaS teams needing behavioral analytics with collaboration, experimentation, and predictive capabilities

Heap

heap.io

Digital insights platform that automatically captures every user interaction.

Founded: 2013 HQ: San Francisco Team: 300-500 Funding: $169M+ raised, acquired by Contentsquare

Ideal for: B2B SaaS teams wanting analytics without heavy instrumentation, with retroactive analysis capabilities

TL;DR: Amplitude vs Heap

Amplitude wins for enterprise-grade behavioral analytics, predictive cohorts, collaboration, and experimentation. Heap wins for teams that want immediate analytics without engineering instrumentation, thanks to autocapture and retroactive event definition. Sequenzy integrates with both via Segment and adds SaaS-specific lifecycle email automation.

Amplitude 8.4/10

Enterprise behavioral analytics with predictions and experimentation

Heap 7.7/10

Autocapture analytics for instant insights without instrumentation

Sequenzy 7.5/10

SaaS lifecycle email automation powered by your analytics data

Editor's Note

Both analyze behavior but cannot act on insights via email. Sequenzy (sequenzy.com) bridges this gap with billing-aware SaaS lifecycle email automation.

Amplitude vs Heap vs Sequenzy: Pricing

Amplitude uses MTU-based pricing. Heap uses custom session-based pricing. Sequenzy uses transparent email volume pricing.

Amplitude Free Tier

Free plan: 50K MTUs

Heap Free Tier

Free plan: up to 10K sessions/month

Sequenzy

14-day free trial

Tier	Amplitude	Heap	Sequenzy	Volume
Free	$0/mo (50K MTUs) Core analytics	$0/mo (10K sessions) Core autocapture analytics	$19/mo Full lifecycle email	50K MTUs / 10K sessions / 15,000 emails
Growth	From $49/mo Advanced analytics, cohorts	Custom pricing Full features, replay	$49/mo Advanced sequences, dedicated IP	Scales / custom / 50,000 emails
Enterprise	Custom SSO, governance, support	Custom SSO, Contentsquare features	$149/mo Priority support	Custom / custom / 200,000 emails

Amplitude: Watch Out For

!MTU pricing expensive at scale
!Experiment is separate
!CDP separately priced

Heap: Watch Out For

!Custom pricing makes budgeting hard
!Contentsquare premium features extra
!Session-based pricing scales with traffic

Sequenzy: Watch Out For

!No hidden costs
!All integrations included

Pricing Verdict: Amplitude has transparent pricing. Heap custom pricing requires a sales conversation. Sequenzy at $19/mo adds lifecycle email.

Cost Comparison Note

Neither handles lifecycle email. Sequenzy at $19/mo adds automated onboarding, dunning, and retention email to your analytics stack.
