TL;DR
- These three are not really competitors. Outreach and Salesloft are enterprise sales engagement platforms sold per seat with annual contracts. Apollo.io is a data platform with sequencing attached. The comparison is really about whether you are buying workflow or buying data.
- Apollo.io is the strongest fit for teams that need contact data and sequencing in one place, at $49 to $119 per user per month on annual billing, with a free tier and no platform fee.
- Outreach is the strongest fit for large enterprise sales organisations that need deep governance and forecasting, at roughly $100 to $160 per user per month with mandatory annual commitment.
- Salesloft is the strongest fit where forecasting and engagement need to sit in one system, at roughly $125 to $165 per user per month list, dropping to $100 to $130 after negotiation. Salesloft completed its merger with Clari in December 2025.
- The merger matters. Salesloft is now part of a combined Clari and Salesloft entity mid-integration, and packaging is shifting. Verify what is in your quote rather than relying on published feature lists.

What each platform actually is
The most common evaluation mistake here is treating these as three versions of the same product.
Outreach and Salesloft grew up as sales engagement platforms serving enterprise sales organisations. They sequence outreach, manage tasks, integrate deeply with Salesforce, and increasingly sell forecasting and revenue intelligence on top. Neither includes contact data. You bring your own from ZoomInfo, Cognism, or elsewhere, and you pay for that separately.
Apollo.io started as a contact database and added sequencing. It includes 270M+ contacts and 65+ search filters in the subscription. For a team without an existing data contract, that inclusion is worth more than any workflow feature either incumbent offers.
So the real question is not which platform is better. It is whether your binding constraint is workflow governance across a large rep population, or access to contacts at a predictable cost.

Outreach in detail
Best for: Large enterprise sales organisations where governance, role-based permissions, and revenue analytics across hundreds of reps are the binding constraint.
Outreach has repositioned around agentic AI, marketing itself as a revenue orchestration platform covering prospecting, deal management, forecasting, coaching, and account expansion. The company states that it helps sellers close over two million opportunities every month.
Pricing: Outreach does not publish list pricing. Quote-based, per user per month, typically requiring a full annual commitment paid upfront. Three primary tiers exist: Standard, Professional, and Enterprise. Third-party sources converge on roughly $100 to $140 per user per month for the base Engage tier before module add-ons. One breakdown of the Amplify packaging places Amplify Core at approximately $100 to $120 per user per month, Amplify Plus at $130 to $160, and Amplify Pro at $160 or more on a custom quote. For twenty users, that puts Amplify Core at roughly $24,000 to $28,800 per year and Amplify Plus at $31,200 to $38,400.
Where it falls short: No contact data is included, so the real stack cost is higher than the per-seat figure suggests. Modules for Meet, Deal, Forecast, and Amplify stack on top of the base. Pricing opacity makes budgeting difficult, and the platform requires a genuine implementation project rather than a self-serve setup.
Verdict: The strongest fit at the top of the market where the governance requirement is real. For a twenty-rep team, the cost and complexity are difficult to justify against Apollo.
Salesloft in detail
Best for: Revenue organisations that want engagement and forecasting under one roof and are comfortable buying into a platform mid-integration.
Salesloft's packaging has consolidated around Advanced and Elite, with several capabilities available as add-ons rather than tiers. Advanced covers pipeline-building workflows, cadence management, CRM sync, and analytics. Elite adds multi-team support, sandbox functionality, and custom CRM signals. Forecasting, account agents, coaching agents, and the dialer may all be priced separately.
Pricing: Not published. Third-party data converges on $125 to $165 per user per month at list, dropping to $100 to $130 for mid-market teams after negotiation. Vendr data shows Advanced tier buyers with 25 to 75 users often achieving $100 to $130 per user per month. One analysis reports observed list prices ranging from $80 to $250 per user per month across Essentials, Advanced, and Premier, plus an initial platform fee of $5,000 to $25,000, an optional dialer at $25 to $40 per user per month, and one-time implementation fees of $5,000 to $30,000. For a ten-rep team on Advanced, that source estimates a total annual budget of $17,000 to $35,000. Buyers reportedly negotiate 35% to 45% discounts at the end of Salesloft's fiscal quarters in April, July, October, and January.
Where it falls short: The dialer and conversation intelligence are add-ons, not inclusions, which makes headline per-seat comparisons misleading. The Clari merger completed in December 2025 means packaging and renewal economics are actively shifting.
Verdict: Competitive with Outreach on capability and now differentiated by the Clari forecasting layer. Buy with clear written confirmation of what is included versus what is an add-on.
Apollo.io in detail
Best for: Teams that need contact data and sequencing together, want transparent pricing, and do not need enterprise governance.
Apollo bundles a 270M+ contact database with 65+ search filters, sequencing, a dialer, and waterfall enrichment from the Basic tier upward. It is the only platform of the three with published pricing and a free tier.
Pricing: Free tier available. Basic at $49 per user per month on annual billing, or $59 monthly. Professional at $79 annual, or $99 monthly. Organization at $119 annual with a three-seat minimum, or $149 monthly. Credits expire each billing cycle. Phone credits consume roughly eight times an email credit. Overage runs approximately $0.20 per credit with a 250-credit minimum purchase.
Where it falls short: Data quality is the trade-off. Reported accuracy sits around 65% to 70% with bounce rates of 15% to 25% per G2 and Trustpilot reviews, which is materially below what a dedicated provider like Cognism or Findymail delivers. Credit expiry punishes uneven usage. Enterprise governance, territory management, and forecasting depth do not approach Outreach or Salesloft.
Apollo acquired Pocus in March 2026 to add a signal intelligence layer, and reports over 400% growth in enterprise accounts over the preceding twelve months. The platform is moving upmarket, but the governance gap against the incumbents has not closed yet.
Verdict: The strongest fit for teams under roughly fifty reps, and the only option here where the data cost is inside the subscription rather than beside it.
The Clari merger and what it changes
Clari and Salesloft completed their merger in December 2025, appointing Steve Cox as CEO of the combined organisation. The combined entity positions itself as building the first Predictive Revenue System, doubling R&D investment, and unifying data, workflows, and sales engagement.
Three practical consequences follow for anyone evaluating right now.
The forecasting story is now genuinely differentiated. Clari's forecasting and pipeline inspection layer is the strongest in the category, and pairing it with Salesloft's engagement layer removes an integration that most enterprise teams were building themselves.
Packaging is unstable. Groove, which Clari acquired previously, has been folded into Salesloft branding. Reported module pricing for the combined stack runs $100 to $120 per user per month for Clari Forecast, $60 to $110 for Clari Copilot, and $50 to $80 for the Salesloft engagement layer, reaching $200 to $310 or more per user per month for the full stack. Implementation runs $15,000 to $25,000 for standard deployments and $50,000 to $75,000 for complex enterprise rollouts.
And renewal terms deserve scrutiny. Mid-integration vendors frequently reprice at renewal. Negotiate a renewal cap in the initial contract rather than discovering the increase in twelve months.
Total cost of ownership for a 20-rep team
The per-seat number is not the cost. Here is a like-for-like model at twenty reps, annual billing, including the data layer each platform requires.
| Line item | Outreach | Salesloft | Apollo.io |
|---|---|---|---|
| Platform seats | ~$28,800 | ~$30,000 | $18,960 |
| Platform fee | Varies | $5,000 to $25,000 | $0 |
| Implementation, year one | Separate | $5,000 to $30,000 | $0 |
| Dialer | Module | $6,000 to $9,600 | Included |
| Contact data | $15,000 to $25,000 external | $15,000 to $25,000 external | Included |
| Approximate year one | $48,000 to $60,000+ | $61,000 to $95,000+ | $18,960 |
The gap is not a quality gap. It is an inclusion gap. Outreach and Salesloft assume you already buy data elsewhere and price accordingly. Apollo folds it in and accepts lower data accuracy as the trade.
The honest framing: if your data quality requirement is high enough that Apollo's 65% to 70% accuracy is unacceptable, you were always going to pay for Cognism or a waterfall stack, and the incumbent premium is smaller than the table suggests.
Which platform fits which team
| Situation | Strongest fit | Why |
|---|---|---|
| Under 50 reps, need data included | Apollo.io | Data plus sequencing in one predictable subscription |
| Enterprise, need governance at scale | Outreach | Deepest role, territory, and permission model |
| Forecasting accuracy is the priority | Salesloft | Clari layer is the strongest forecasting product |
| Already own a data contract | Outreach or Salesloft | Apollo's data inclusion is not a differentiator for you |
| Want to start today without procurement | Apollo.io | Free tier and self-serve signup |
| Salesforce is the system of record | Outreach or Salesloft | Deeper native Salesforce object handling |

FAQ: Outreach vs Salesloft vs Apollo.io
How much does Outreach cost per user in 2026?
Outreach does not publish pricing. Third-party estimates converge on roughly $100 to $140 per user per month for the base tier, rising to $160 or more for the top tier on a custom quote. For twenty users, expect roughly $24,000 to $38,400 per year before module add-ons and before contact data.
How much does Salesloft cost per user in 2026?
List pricing is reported at $125 to $165 per user per month, dropping to $100 to $130 for mid-market teams after negotiation. Add a platform fee of $5,000 to $25,000, implementation of $5,000 to $30,000, and a dialer add-on of $25 to $40 per user per month if you need calling.
Is Apollo.io a real alternative to Outreach and Salesloft?
For teams under roughly fifty reps, yes. Apollo covers sequencing, dialing, and contact data in one subscription at a fraction of the cost. Above that, the governance, territory management, and forecasting gaps become material and the incumbents earn their premium.
What changed when Clari and Salesloft merged?
The merger completed in December 2025 with Steve Cox as CEO of the combined company. Salesloft's engagement layer now sits alongside Clari's forecasting and pipeline inspection. Groove has been folded into Salesloft branding. Packaging and renewal economics are shifting, so confirm inclusions in writing.
Which platform has the best contact data?
Only Apollo includes contact data, with 270M+ contacts and reported accuracy around 65% to 70%. Outreach and Salesloft include none, so their data quality depends entirely on the provider you pair them with. A Cognism or waterfall enrichment stack alongside Outreach will beat Apollo's native data comfortably, at additional cost.
When is the best time to negotiate these contracts?
End of the vendor's fiscal quarter. For Salesloft those are April, July, October, and January, with reported discounts of 35% to 45%. Outreach follows a similar pattern. Apollo's published pricing leaves less room, though annual billing already saves roughly 15% to 25% over monthly.
