The third perspective on Clay vs Apollo
Clay vs Apollo, and the SMB row neither one has.
Apollo wins for outbound sequencing on a single per-seat bill. Clay wins as the workflow surface that calls many providers and runs AI research per row. Both are profile-built, so both thin out at the single-shop operator.
If your ICP is the mid-market software buyer with a LinkedIn profile, you have two good options. If your ICP is the dental practice with no website, you need a third.
Three jobs, three tools
Apollo is the seat. Clay is the workflow. Orbital is the row.
Most Clay vs Apollo posts treat the choice as binary. An outbound stack in 2026 rarely is. Apollo is a per-seat contact database plus sequencing. Clay is a workflow surface that calls many data providers and runs AI research per row. Orbital is the SMB row beneath both, where 82 percent of practices are single-location and the LinkedIn anchor is missing.
What Apollo is
Mid-market contact database with sequences in the same seat.
Apollo's wedge is broad contact coverage at the profile grain, plus outbound sequencing on the same login. The free tier and per-seat pricing get a small SDR team running without procurement. International coverage outside the US is broader than most US-built competitors.
Best for: a sales team running high-volume outbound against software, services, or mid-market ICPs that map cleanly to LinkedIn, that wants sequencing and data on one bill.
What Clay is
A workflow surface that calls many providers and adds AI per row.
Clay's wedge is the spreadsheet-shaped table where you stack data sources in a waterfall, run AI research per row, and push the enriched record out. Clay added a native Sequencer in 2026, email-focused, though heavier outbound still runs in Apollo or a dedicated tool. It usually consumes Apollo or other providers as one of its sources, so the cost of Clay sits on top of the underlying data spend.
Best for: a RevOps lead who wants programmable enrichment, can write a column formula, and already pays for sequencing somewhere else.
What Orbital is
A company-grain map of the long-tail US small business.
Orbital maps 13,549,104 US small businesses, including the single-location operators with no website, no LinkedIn company page, and no decision-maker profile online. Then our agents attach the custom signals you score on, per account, instead of a flat enrichment column.
Best for: a team selling into SMB trade or healthcare verticals, that needs depth on the small operators a profile-built graph never surfaces, and that runs sequencing in Apollo, HubSpot, Outreach, Salesloft, Smartlead, or Instantly.
The honest comparison
Nine rows. Apollo wins two. Clay wins two. We win three. Two are split or model-dependent.
Most Clay vs Apollo posts hand the win to whichever tool the author resells. This one names the rows each tool owns. If the row does not exist in a profile-built graph, we say so plainly, and we say where we lose to Apollo's sequencing and Clay's workflow surface as well.
| Dimension | Orbital | Clay.com | Apollo.io | Winner |
|---|---|---|---|---|
| Outbound sequencing in the same tool | Not in product. Orbital pushes records to HubSpot, Outreach, Salesloft, Smartlead, or Instantly for sequencing. | Native Sequencer added in 2026, email-focused and billed as Actions. Newer and lighter than Apollo's, with no dialer. | Built in. Sequences, A/B tests, and call dialer live alongside the contact database on the same seat. | Apollo |
| Native contact database depth | Long-tail SMB depth at the company grain. Sparse on mid-market software firmographics. | No native contact graph. Clay calls Apollo, ZoomInfo, Hunter, RocketReach, and other providers as data sources, then waterfalls. | Native database of roughly 275M contacts across 73M companies (source: apollo.io). Profile-grain. | Apollo |
| Workflow surface and per-row enrichment | Per-account agents attach signals you define. Not a programmable spreadsheet surface. | The spreadsheet-shaped surface with column formulas, waterfalls across providers, and AI research per row. The core product. | Filter-and-list interface, not a per-row workflow surface. Sequences live next to the database. | Clay |
| AI research per row (Claygent-style) | Custom agent signals on a per-account basis, scoped by you. Different shape than per-row AI prompts in a table. | Claygent and equivalent AI columns. Run prompts against any record, with provider fallback. The flagship feature. | Templated AI assist for sequence copy. Not arbitrary research per row. | Clay |
| Long-tail SMB at the company grain | 13,549,104 US small businesses mapped, including single-location operators with no website and no LinkedIn page. | Inherits the SMB depth of its underlying providers. Most of those providers are profile-built, so the long tail thins out. | SMB rows exist, but depth thins out at the single-location, no-LinkedIn operator. The graph is profile-built. | Orbital |
| Decision-maker contacts at single-location SMBs | Practice-level emails plus matched owner contacts, for businesses where 74 percent of US dental decision-makers have no LinkedIn. | Quality depends on which provider hit. If every provider needs a profile, the owner with no LinkedIn is a blank row. | If the owner has no LinkedIn profile, the contact is mostly not in the graph. | Orbital |
| Local-business signals (no website, no GBP, no LinkedIn) | Surfaced as first-class fields. The whole point of the company-grain pull. | Possible to build a workflow that infers these, but not first-class fields. Cost compounds per row. | Not a native filter. Apollo is built profile-up, not company-down. | Orbital |
| Pricing model | Per-account or platform price tied to the verticals and signals you run. Contract terms negotiated. | Credit-based. After the March 2026 repricing, Launch is 185 and Growth is 495 USD per month, with legacy tiers (149 to 800) open to existing customers only. Provider costs are extra. | Per-seat with a free tier, then tiered paid plans (source: apollo.io/pricing). Bundles data and sequencing. | Model-dependent |
| CRM and sequencer integration breadth | HubSpot, Salesforce, Attio, CSV. Narrower than Apollo on sequence-state sync, deeper than Clay on company-grain mapping. | Wide push-out menu: HubSpot, Salesforce, Outreach, Salesloft, Smartlead, Instantly, plus webhooks. | Deep native sequencer integrations, especially state sync from Apollo sequences into Salesforce and HubSpot. | Orbital, for SMB workflows; Apollo and Clay for stack breadth |
Methodology: Orbital figures from a curated company-grain pull, data as of April 2026, US sourced. Apollo figures cited from apollo.io and its public pricing page as of 2026-04. Clay figures cited from clay.com public pricing and product documentation as of 2026-04. Where a row is provider-dependent (Clay), the cited limits reflect the median of three published Clay-provider integrations.
Decision rules
Three criteria each. If two of three match, you have your answer.
Pick the tool whose limits you can live with. Most outbound teams selling into SMB end up running two of the three side by side. Sales tools are not religions.
Pick Apollo if
- You need a contact database and outbound sequencer on the same seat and the same bill.
- Your TAM is global or mid-market software, services, or enterprise verticals that map cleanly to LinkedIn profiles.
- Your team starts in a free tier and grows on per-seat, without a procurement cycle.
Pick Clay if
- You want a programmable workflow surface to combine providers and run per-row AI research, with a light native Sequencer for email.
- Your RevOps lead can write column formulas and is comfortable owning a credit-based enrichment budget.
- Your ICP is varied enough that no single contact database covers it cleanly and you need waterfalls.
Pick Orbital if
- You sell into trade or healthcare SMB verticals where 82 percent of practices are single-location and 54 percent have no website.
- You need decision-maker contacts at the single-shop operators a profile-built graph never surfaces.
- You want custom agent signals attached per account so the list arrives scored on your ICP, not in scraper order.
The stack we see most often
How outbound teams selling into SMB wire these three together.
A pattern we see in roughly one in two SMB-focused outbound stacks: Apollo as the sequencer plus mid-market contact source, Clay as the workflow surface for enrichment, Orbital as the row supplier for the long-tail SMB layer. Each tool plays its position. The cost compounds, but so does the contact rate.
Apollo for outbound sequencing, mid-market contact volume, and the free or per-seat tier. Receives enriched records out of Clay, fires sequences, syncs state back to the CRM.
Clay for the workflow surface, provider waterfalls, and per-row AI research. Reads from Apollo, Orbital, and other providers, runs the column formulas, writes back to the CRM and sequencer.
Orbital for the long-tail SMB row. Feeds Clay's enrichment workflows with the single-location dental practice, the no-website HVAC contractor, the owner-operator restaurant the profile graph never had. The bottom row of the stack is the row the others cannot generate.

The argument in one paragraph
A row that does not exist in a profile graph is not a row a workflow can rescue.
Apollo built a contact database the way most modern tools build them, by anchoring on professional profiles. Clay sits on top of those graphs and runs a workflow over them. Both are excellent at what they do. Both share a starting assumption: the person you want to reach has a profile.
That assumption holds for most of mid-market software and most of enterprise. It does not hold for the long-tail SMB. Of the US dental practices Orbital tracks, 54 percent run without a website and 74 percent have no decision-maker on LinkedIn. Of US restaurants Orbital tracks, 82 percent have no LinkedIn company page. Those are not edge cases. That is the shape of the long-tail SMB.
Orbital is built the other way. We map the company population from Google Maps, Yelp, and Yellow Pages, all 13,549,104 of them, find the owner with a 51-source agent, then attach contacts two ways: matched from professional profiles where they exist, and practice-level emails sourced directly from the businesses themselves where they do not. The same pull powers the dentist email list, the HVAC email list, the med spa email list, the restaurant email list, and the roofing email list pages on this site, all built from the same company-grain pull.
The honest trade is this. Apollo will outprice us on a small SDR team running global outbound on a per-seat plan with sequencing in the same window. Clay will out-flex us on a programmable enrichment workflow that calls many providers and runs AI per row. We will give you the SMB row neither tool has, with the signal attached that says why the row matters for your ICP. Pick the limits you can live with.
Questions
Before you commit to a stack.
Clay vs Apollo: which one should I pick?
Pick Apollo if you want a single-tool seat that bundles a contact database with outbound sequencing, with a free tier and per-seat pricing. Pick Clay if you already have sequencing handled and want a workflow surface that combines multiple data providers, enrichment waterfalls, and AI research per row. Pick Orbital if your ICP is the long-tail US SMB, where 82 percent of practices are single-location and 74 percent have no decision-maker on LinkedIn. The honest answer: most outbound teams selling into SMB end up using two of the three.
Is Clay better than Apollo?
Different products. Apollo is a contact database plus sequencing in one seat. Clay is a workflow tool that calls into many contact databases, including Apollo as one of its providers, and runs AI enrichment per row. If you treat Clay as a workflow surface and Apollo as a data source, Clay is more flexible and Apollo is cheaper. Most teams running Clay still pay one or more of the underlying providers.
Is Clay an Apollo replacement?
Not quite. Clay consumes Apollo's contact database rather than replacing it. A common Clay setup pulls from Apollo plus three or four other providers in a waterfall, then layers AI research on top. Clay replaces the spreadsheet enrichment script. The contact graph stays.
How does Clay vs Apollo pricing compare?
Apollo charges per seat, with a free tier and paid plans from roughly 59 to 149 USD per user per month, month-to-month. Clay is credit-based: after its March 2026 repricing, Launch is 185 and Growth is 495 USD per month, with legacy tiers open to existing customers only. Apollo bundles sequencing and a dialer in the seat. Clay added a native Sequencer in 2026, email-focused, so lighter outbound can run inside Clay while heavier dialing still lives in Apollo.
Do Clay or Apollo cover long-tail SMBs?
Both have SMB rows, both thin out at the single-location operator. Apollo's graph is profile-built. Clay's coverage depends on which providers it pulls from, and most of those providers are also profile-built. Of the 13,549,104 US small businesses Orbital maps, a meaningful slice has no website, no LinkedIn company page, and no decision-maker profile online. Profile-built graphs skip those rows by default.
Can I use Clay, Apollo, and Orbital together?
Yes, and that is the most common shape we see in outbound stacks. Apollo for mid-market and global contact volume on the per-seat plan. Clay for the workflow surface that combines providers and runs per-row AI research. Orbital underneath for the long-tail US SMB layer where 82 percent of US dental practices are single-location and the row does not exist in a profile-built database. Each tool plays its position.
Does Orbital push data into Clay or Apollo?
Orbital exports a flat record per company and per contact, with CRM mappings for HubSpot, Salesforce, Attio, plus CSV. Many customers run Orbital as the SMB row source feeding Clay's enrichment workflows, then push the enriched record into Apollo, Outreach, Salesloft, Smartlead, or Instantly for sequencing. We do not sequence ourselves.
Can I get a sample of the long-tail SMB data?
Yes. Tell us the SMB vertical or geography you sell into and we send a sample of around 100 records so you can compare them to what Clay or Apollo returns on the same account list. No contract, no signed order required to evaluate.
