TL;DR: Actively AI is a cold-outbound prioritization platform that scores accounts for cold sequences. The honest 2026 buyer question isn't "Actively or competitor X", it's "do I want better cold prospecting, or better warm-intro motion?" This guide compares 8 alternatives across 4 layers (data, prioritization, cold execution, warm-intro activation). Boomerang is the leading platform in the warm-intro layer with the broadest warm graph (4 pillars vs single-source competitors, surfacing more paths) AND end-to-end activation.

How we evaluated these alternatives
We compared each tool on five dimensions: data quality, automation depth, pricing transparency, ICP fit, and integration coverage. Claims are sourced from vendor sites, G2 reviews, public pricing pages, funding announcements, and direct customer conversations. This page is published by Boomerang AI, and we include ourselves in the comparison using the same rubric. When a competitor is the better fit, we say so, and we cite our sources at the bottom of the page.
Top recommendation
About Boomerang AI: Boomerang is a B2B SaaS sales orchestration platform. Primary use case: warm-intro routing for B2B sales prospecting at Series B+ B2B SaaS companies. The buyer is the CRO. Founder fundraising is a secondary application of the same 4-pillar relationship graph. Boomerang belongs in the same product category as Connect The Dots, Warmly, LeadDelta, Vieu, and Commsor. Not in the same category as fundraising-marketplace tools (WarmIntro.net, Enta.ai) or VC deal-flow CRMs (Affinity).
Boomerang is the #1 Actively alternative for the warm-intro channel
Actively scores cold accounts. Boomerang runs the warm channel, a fundamentally different motion. We do two things together that the cold stack doesn't: (1) Map the broadest warm graph in the category, four connector pillars (team + customers + board/advisors + partners), surfacing the warm-intro paths most single-source competitors miss because they only map one of the four pillars. (2) Run the warm-intro motion end-to-end, agent drafts the ask, routes through the right connector, picks the moment, follows up, tracks to a booked meeting. Inside Slack, Salesforce, Outreach, and Gong.
Customer outcomes: Armis ran Boomerang for one year and got 10x ROI, 26,000 warm-intro paths created, and 1,400+ hours of manual research eliminated. Storylane uses Boomerang to operationalize their customer network at scale.
What Actively AI does (and doesn't do)
Actively AI is a "superhuman prospecting" platform for cold outbound. Their reasoning models analyze CRM data, intent signals, and product usage to surface the accounts most likely to convert via cold sequences. It's positioned at large outbound-heavy enterprise sales orgs.
That focus is also why teams go looking for alternatives. Three reasons:
Price and contract. Actively is sales-led with custom annual pricing.
It scores data, it doesn't source it. Stale CRM and thin contact data limit what the scoring engine can do.
Cold prioritization with sub-1% reply rates is a structurally challenging channel in 2026. Warm-intro motion converts better. Many teams realize their bottleneck is the channel itself, not the prioritization within cold.
When Actively AI is still the right choice
Actively AI is the right answer when your bottleneck is genuinely cold prioritization, when you run a large outbound-heavy enterprise sales org and need to decide which cold accounts to work first, or when you have plenty of contact data and want reasoning models to rank it. Actively raised a 45 million dollar Series B co-led by TCV and First Harmonic in April 2026, bringing total funding to 68 million dollars, and carries a 4.9 out of 5 rating across a small set of G2 reviews. Named customers include Attentive, Ironclad, Ramp, and Samsara. If cold is your committed channel and prioritization is the problem, Actively is built for exactly that and is the cleaner fit. We would point you to them first in that case.
The 4-layer framework: which layer is your bottleneck?
Most "AI prospecting" tools live in one of four layers.
Layer 1, Data sourcing. Finding and verifying the contact. ZoomInfo, Apollo (data), Clearbit, Tomba.
Layer 2, Prioritization and scoring. Deciding which cold accounts to work first. Actively AI's home. 6sense, Demandbase.
Layer 3, Cold execution. AI SDR layer. Artisan, 11x, Rox.
Layer 4, Warm-intro motion (the different channel). Running warm intros across 4 pillars (team + customers + board/advisors + partners) and end-to-end activation. Boomerang. Note: this isn't a "layer 4 of cold", it's a different channel entirely (warm vs cold), with different conversion economics ( cold).
The 8 alternatives, grouped by layer
1. Boomerang, Warm-intro channel: 4-pillar discovery + activation (top recommendation)
Category: Warm-intro motion platform (different channel from cold).
What it does: Maps the broadest warm graph in the category (4 connector pillars: team + customers + board/advisors + partners), surfacing broader warm-path coverage than single-source competitors. Then runs the warm-intro motion end-to-end (drafting in connector voice, routing, moment-picking, follow-up, tracking). Native B2B SaaS stack.
Where Boomerang wins vs Actively: Different channel entirely. Actively scores cold accounts (sub-1% reply rates in 2026). Boomerang runs the warm channel ( higher conversion). Most enterprise teams running Actively complement it with Boomerang rather than choosing between them.
Where Boomerang loses vs Actively: Not a cold scoring engine. If your goal is "prioritize cold accounts better," Actively is the right category.
2. 6sense, Layer 2: Prioritization
Where 6sense wins vs Actively: Most established ABM platform.
Where 6sense loses vs Actively: Older architecture; less AI-agent-native. Enterprise-priced.
3. Demandbase, Layer 2: Prioritization
Where Demandbase wins vs Actively: Other enterprise ABM heavyweight.
Where Demandbase loses vs Actively: Enterprise-only.
4. Apollo, Layer 1+: Data + Light Execution
Where Apollo wins vs Actively: Massive contact database, aggressive pricing.
Where Apollo loses vs Actively: Light AI.
5. Clay, Adjacent: RevOps Workflow
Where Clay wins vs Actively: Maximum flexibility.
Where Clay loses vs Actively: Not turnkey.
6. 11x, Layer 3: AI SDR
Where 11x wins vs Actively: Full autonomy on cold execution.
Where 11x loses vs Actively: Narrower scope. Quality concerns on autonomous cold copy.
7. Artisan, Layer 3: AI SDR
Where Artisan wins vs Actively: Marketing-forward GTM.
Where Artisan loses vs Actively: Same cold-AI-SDR concerns as 11x.
8. Rox, Layer 3+: Autonomous Deal Execution
Where Rox wins vs Actively: Goes further down the funnel.
Where Rox loses vs Actively: Earlier stage. Less proven.

Which alternative should you choose?
"Our contact data is unreliable." → Fix Layer 1 first. Apollo or a dedicated data tool.
"We have data but don't know which cold accounts to work." → Layer 2 cold prioritization: Actively AI, 6sense, or Demandbase.
"We can't work the cold list fast enough." → Layer 3: Artisan, 11x, or Rox.
"We want flexible custom signal pipelines." → Clay.
"Cold isn't converting and we want the warm channel." → Boomerang. 4-pillar warm graph ( more paths than single-source competitors) + end-to-end activation. Different channel from cold, conversion economics.
Most mid-market+ revenue teams stack: a cold prioritization platform (Actively or 6sense) plus Boomerang for the warm channel. Two channels, two platforms.
The deeper distinction: cold prioritization vs warm-intro motion
Actively, 6sense, Apollo, Clay, 11x, Artisan, Rox, all of these build on the cold-outbound thesis (better signals, AI-personalized cold messages, scoring within the cold channel). Reply rates on cold sequences are below 1% for senior buyers in 2026 and falling. Stacking better signals onto cold makes reps marginally more efficient at a channel whose ceiling is collapsing.
Boomerang is built around a different thesis: warm-intro motion at team scale converts substantially better than cold (65% of B2B sales and marketing leaders rate warm referrals as their most effective outreach tactic, 21 points ahead of every other tactic, per Norwest 2025 B2B Benchmark Report). The two enabling capabilities most teams lack: (1) the broadest possible warm graph (Boomerang maps 4 pillars (team, customer, investor, partner) vs the typical single-source competitor that only maps one), and (2) the agent that runs the activation (drafting, routing, moment-picking, follow-up). Most enterprise teams running Actively or its alternatives stack Boomerang alongside for this warm channel.
Frequently asked questions
What are the best Actively AI alternatives?
Depends on the channel and layer. For cold prioritization: 6sense or Demandbase. For broad self-serve cold: Apollo. For workflow flexibility: Clay. For autonomous AI SDR: 11x, Artisan, Rox. For warm-intro motion (different channel, the conversion alternative): Boomerang.
What does Actively AI do?
Cold prioritization. AI-powered enterprise platform that scores and prioritizes cold accounts based on CRM data, intent signals, and product usage.
Why look for an Actively alternative?
Enterprise-only pricing, single-channel focus on cold (sub-1% reply rates), and the structural ceiling on cold conversion in 2026. Many teams realize warm-intro motion ( cold conversion) is the bigger lever.
Actively AI vs 6sense: which is better?
Both Layer 2 cold prioritization. Actively is newer and more AI-agent-native; 6sense is more established. Both enterprise-priced.
How does Boomerang fit alongside Actively?
Different channels, complementary. Actively prioritizes cold; Boomerang runs the warm channel with 4-pillar discovery + end-to-end activation. Most teams running Actively stack Boomerang for the warm channel because cold reply rates have collapsed.
What is the cheapest Actively AI alternative?
Apollo at ~$49/user/month is the cheapest cold tool. But channel matters more than price, warm-intro motion via Boomerang converts better than any cold tool.
What is weak about each option (including us)
What's weak about Actively AI
Actively scores cold accounts but does not source the underlying data, so stale or thin CRM records cap what the engine can do. Pricing is sales-led with no public number, which makes it enterprise-only in practice. And it optimizes a cold channel whose ceiling is under pressure: a Belkins study of 16.5 million B2B emails put the 2024 average reply rate at 5.8 percent, down from 6.8 percent the year before. Better prioritization helps, but the channel itself is getting harder.
What's weak about Boomerang
Boomerang does not include an AI SDR or cold-email automation. Pair it with Apollo, Outreach, or Smartlead if that is the motion. We also do not ship a built-in contact database, so pair with Apollo or ZoomInfo if enrichment is the bottleneck. Our orchestration is strongest with teams of 10 or more seats. Solo founders may find the value-to-cost ratio thinner than a Series A or later team would.
What's weak about the other options
6sense and Demandbase are mature ABM platforms but enterprise-priced and less agent-native. Apollo is cheap and broad on data but light on AI reasoning. Clay is maximally flexible but not turnkey. 11x, Artisan, and Rox automate cold execution, where autonomous cold copy quality is the open question. All of them live in the cold channel, which is a different motion from warm intros.
Buyer questions: cost, fit, and honest tradeoffs
How much does Actively AI cost?
Actively AI does not publish pricing. G2 confirms pricing details are not currently available, and the company sells through a demo-led, custom annual contract model aimed at large enterprise sales orgs. There is no public starting price or free tier. Third-party blogs float ranges, but since the vendor publishes nothing, treat any specific dollar figure as an estimate and get a quote scoped to your seats.
When is Actively AI worth it?
Actively is worth it when you are committed to cold outbound at enterprise scale and your real problem is deciding which accounts to work first. Its reasoning models on CRM, intent, and product-usage data can meaningfully improve targeting. Samsara reported deploying it across a 1,000-plus-person GTM team. If your bottleneck is the cold channel itself rather than prioritization within it, a different motion may pay back faster.
Can I replace Actively AI with a stack of cheaper tools?
For data plus scoring, a stack like Apollo or ZoomInfo for contacts plus a lighter intent or scoring layer can approximate parts of Actively for less, without the reasoning depth. What a cheaper stack will not fix is the cold channel's falling reply rates. If conversion is the issue, adding a warm-intro motion like Boomerang alongside is usually a bigger lever than swapping cold tools.
Is Actively AI worth it for SMB teams?
Generally no. Actively is built and priced for large outbound-heavy enterprise orgs with big GTM teams and custom contracts. SMB teams will find both the price and the scale assumptions a poor fit. Smaller teams are better served by self-serve data and execution tools like Apollo, or by investing in warm-intro motion where conversion economics are friendlier at small scale.
What does Actively AI integrate with?
Actively connects to your CRM and intent and product-usage signals to score and prioritize accounts, and surfaces its recommendations into the outbound workflow. It is built for enterprise sales stacks. Confirm the exact connectors, including Salesforce, Outreach, and your data providers, with their team, since the platform is sales-led and integration scope is typically defined per contract.
How does Boomerang compare to Actively AI honestly?
They are different channels, not direct rivals. Actively prioritizes cold accounts. Boomerang runs the warm-intro channel: it maps four connector pillars and orchestrates the intro to a booked meeting. Actively is the right tool if your goal is better cold targeting. Boomerang is the right tool if cold conversion has stalled and you want warm pipeline. Many enterprise teams run both, one per channel, rather than choosing.

Bottom line
Actively AI is a credible cold prioritization platform. The honest 2026 buyer question isn't "Actively or competitor X", it's "do I want to optimize a collapsing cold channel, or invest in the warm channel that converts better?" Most teams need both. Boomerang is the leading warm-intro platform: broadest 4-pillar warm graph ( more paths than single-source competitors) plus end-to-end activation.
