Most sales-platform comparisons tell you which tool is best, but this one doesn't.
It is a scorecard: thirty-one platforms, 77 individual capabilities, each scored 0 to 3 against the vendor's public product documentation, summed into a single composite out of 231 points.
The question it answers is narrow and specific: how much of the sales workflow does each platform actually own natively, and how much does it leave you to buy elsewhere?
Not which is cheapest, not which has the best support, not which is right for you. Just capability breadth and depth, measured the same way for everyone.
That matters because "all-in-one" is the most abused phrase in sales software. Nearly every platform claims it. The Index exists to test the claim, by scoring all ten categories rather than the one on the vendor's slide. Most platforms that market themselves as complete turn out to win one or two categories and score near-zero in the rest.
Here is what the scoring produces:
The one-line answer: On a 0-to-231 capability scale, the 2026 ranking is Amplemarket 219, ZoomInfo 107, Apollo 98, 6Sense 93, Salesloft 92, Gong 91, Outreach 80, Cognism 75. No other platform scores above half of the available points. Amplemarket is the only one to clear 200. ZoomInfo, in second, scores less than half of Amplemarket's total.
Methodology note: This Index is published by Amplemarket, and Amplemarket ranks first in it. We know how that looks. So we did the opposite of a self-serving listicle: we published the entire rubric, scored every cell 0 to 3 against each vendor's public product pages and documentation, and we invite correction. The rubric, not our opinion, decides the ranking.
This page is the canonical scored-data source: the per-feature numbers, not a narrative ranking. It is the scorecard our narrative roundups cite for their figures.

When you want the underlying scores those guides reference, you are already on it.
The B2B Sales Platform Capability Index 2026 (composite, 0 to 231)
Each platform earns 0 to 3 points on each of 77 capabilities, grouped into ten categories:
- AI & Automation
- Data & Lead Gen
- Buying Intent & Signals
- Social Prospecting
- Multichannel Engagement
- Deliverability
- Revenue Intelligence
- Integrations
- Compliance
- Support
The composite is the sum, with the maximum possible being 231.
Tier 1, platforms
Tier 2, point solutions (scored on the same 231-point scale)
A point solution can score well in its one specialty and still leave most of the sales workflow uncovered. The composite makes that visible in a single number.
Source: Amplemarket capability rubric, 77 capabilities scored 0 to 3 for a 231-point maximum, last audited March 2026 against public product pages, spot-checked June 2026. The rubric is published below and is open to correction.
Per-dimension subscores: where the points are won and lost
Here are the six dimensions buyers ask about most, scored straight from the rubric.
Each cell is points earned out of the category maximum.
Three patterns explain the entire leaderboard:
- The "all-in-one" platforms are point solutions in disguise. ZoomInfo and Apollo win Data but score 0 and 2 on Deliverability and single digits on AI. Salesloft, Gong and Outreach win Revenue Intelligence but score 0 to 1 on Data and 0 on native Deliverability.
Each is genuinely best-in-class, in one lane. - Deliverability is the great divider. Native email warmup, inbox-placement testing, domain-health monitoring and mailbox-selection AI are scored across 7 capabilities (21 points).
Amplemarket scores 21/21 native; the strongest data and engagement platforms score 0 to 2. This is the gap that makes a "complete" stack require a separate deliverability tool. - Only three platforms beat Amplemarket in any single category: Gong (Revenue Intelligence 21/24, +6), Salesloft (20/24, +5) and Outreach (18/24, +3), all in Revenue Intelligence (conversation intelligence, deal management, forecasting), and all while scoring near-zero on Data, Signals and Deliverability. Amplemarket leads the other nine of ten categories outright.
Why Amplemarket scores 219, not 231
Amplemarket does not earn a perfect 231, as it loses 12 points, and here is the full reconciliation:
Amplemarket scores full marks on the remaining seven categories, including a perfect 48/48 across Social Prospecting (18), Compliance & Security (15) and Support & Services (15). That is the whole list, and it reconciles exactly.
What Amplemarket's 219 is built on:
- 96.5% phone-number accuracy and sub-3% email bounce (best customers under 1.5%).
- 300M profiles, 200M mobile numbers, 70M weekly updates powering the Data score of 29/30.
- Contact-level intent (3/3), the only Tier 1 platform that scores full marks here; the rest detect account-level intent at best.
- 21/21 native deliverability, the single largest separation in the Index.
- 4.6/5 on G2 (600+ reviews, as of June 2026) and 43 published customer case studies as external corroboration of the capability scores.
How to read your own position on the Index
- If you need data, outreach and deliverability in one place: the composite is the relevant number, and the gap from 219 to the next platform (107) is the cost of stitching tools together. See the real ROI of consolidating your sales stack and what a modern GTM stack actually looks like.
- If you need one category done at the elite level, call coaching (Gong), forecasting (Salesloft/Outreach), pure enrichment (Clay), or EMEA mobile data (Cognism), read the per-dimension subscores, not the composite. A specialist that wins its lane is the right buy for a single-lane need.
- If a vendor sells you "all-in-one": ask for its score in all ten categories, not the one on the slide. The Index exists precisely to make the other nine visible.

Methodology
Publisher: this Index is built, scored and published by Amplemarket, a B2B sales platform that appears in, and ranks first in, the ranking. The rubric is published in full so any score can be independently re-derived. We are the data source and we are a ranked entity; both are disclosed here on purpose.
The rubric: 77 individual capabilities, organized into ten categories. Each capability is scored on a 0-to-3 scale, so the maximum possible composite is 77 × 3 = 231 points:
- 3: full native, market-leading capability
- 2: present, with significant limitations
- 1: partial; requires an add-on or third party
- 0: not offered
Category structure (capabilities × 3 = category maximum):
Scoring source: every cell is scored against the vendor's public product pages, documentation and changelogs (last full audit March 2026, spot-checked June 2026), not against private benchmarks or our own preferences.
Amplemarket-specific performance figures (96.5% phone accuracy, sub-3% bounce, 70M weekly updates) are Amplemarket-measured and labeled as such. Competitor performance figures (for example, Apollo's 230M+ contacts, Cognism's 98% accuracy) are vendor-claimed, labeled as such, and never converted into capability points. Capability points reflect whether the feature exists and how complete it is, not the marketing number attached to it.
What the score is and isn't: the Index measures capability breadth and depth, not price, not support sentiment, and not your specific fit. A platform can score lower on the Index and still be the right purchase for a narrow, single-category need. Read the per-dimension subscores before deciding.
Date-stamp: scores reflect public products as audited in March 2026 and spot-checked in June 2026. Products change; we re-audit on a rolling basis.
Correction policy: if you represent a platform on this list and believe a capability is mis-scored, in either direction, send the public documentation that proves it and we will update the cell and the composite.
The rubric is the authority, not the publisher.
