For teams that use Clay mainly to go from a list of target companies to contacts with an email and a phone number and then write to them, HappySales is the best Clay alternative, because it runs the LinkedIn company search, the waterfall enrichment and the LinkedIn and email campaign from Claude or ChatGPT without building a table or a workflow. Apollo.io, Origami and Spear are the other alternatives worth comparing: a sales platform with its own contact database, an AI agent that finds buyers and writes to them, and a signal-based outbound service. Clay stays the stronger option when a team needs custom workflows across many data sources. The right alternative depends on how much of Clay you actually use.
What is Clay and what is it used for?
Clay is a go-to-market data and workflow platform: it pulls company and contact data from many third-party providers into tables, enriches each row in a waterfall of providers and runs AI research and automated workflows on top. Sales teams use it to source target accounts, enrich contacts, score inbound leads and feed outreach.
Clay describes itself as infrastructure to get data, run agentic workflows and launch go-to-market plays on a visual canvas, according to its home page (2 November 2026). Claygent, Clay's AI agent, does web research to fill custom data points, and the Clay Sequencer sends cold email sequences from the same workspace.
Clay bills with two units, according to its pricing page checked on 2 November 2026. Actions measure platform work such as running a table, calling an AI model or exporting data, while Data Credits pay for the data bought from providers in Clay's marketplace. Every Clay plan includes unlimited seats, and the Free plan does not include phone number enrichment.
When does a Clay alternative make sense?
A Clay alternative makes sense when a team pays for a workflow platform but uses it for one linear job: list, people, contact details and message. Four questions decide whether that is your case:
- Do you need custom workflows or only the list and the campaign? Clay is built for teams that design their own plays, with custom functions, CRM syncs and AI research columns.
- Who maintains the setup? A Clay table is usually built and maintained by a RevOps lead or a go-to-market engineer. If no one on a five-person sales team owns that role, the tables age with the person who built them.
- How do you want to be billed? Clay charges Actions for platform work and Data Credits for data. Others charge per seat, per profile or per organization; the cheapest model depends on how many people search and how many contacts you enrich.
- Where should outreach run? Clay's own sequencer sends email. A team whose buyers answer on LinkedIn needs a tool that runs LinkedIn steps as well.
Teams that only want Clay inside Claude or ChatGPT, rather than a replacement for the whole platform, have a narrower choice, covered in our comparison of Clay MCP and Apollo MCP alternatives.
The best Clay alternatives for prospecting in 2026
The four Clay alternatives worth comparing for prospecting in 2026 are HappySales, Apollo.io, Origami and Spear. The facts on Apollo.io, Origami and Spear come from each vendor's own site, checked on 2 November 2026.
HappySales
HappySales is the Clay alternative for teams whose prospecting starts on LinkedIn. Where Clay asks someone to build a table and connect providers, HappySales runs the company search, the contact search, the enrichment and the campaign as four steps requested in plain language from Claude, ChatGPT or the HappySales web app, and it bills per organization rather than per seat.
Apollo.io
Apollo.io is a sales platform built on its own database of people and companies, with enrichment, email sequences, a dialer and deal management in one product. Apollo.io sells Free, Basic, Professional and Custom plans, applies one plan to all the seats of an account and shares its credits across the team, according to its pricing page.
Origami
Origami is an AI agent that takes a company's website, works out who is most likely to buy, writes a message to each person and sends the replies to the user's inbox, according to Origami's home page. Origami plans include a monthly amount of usage and unlimited team members, and its sequencer runs email and social cadences of up to 10 steps, according to its pricing page.
Spear
Spear is a trigger-based, human-led outbound service: it watches for buying signals such as a LinkedIn post or a funding round and prepares messages sent from the profiles of a company's executives on LinkedIn, X and Reddit. Spear's Starter plan is billed per profile per month with no credits, according to its pricing page, and every prospect is approved by the team before outreach.
Clay alternatives compared: 2026 table
HappySales is the only tool in this table that starts from LinkedIn's company search and runs LinkedIn and email steps in one sequence from an AI assistant. The rows for the other vendors come from their official sites, checked on 2 November 2026.
| Tool | What it is | Where the data comes from | How it enriches | How it bills | Launches campaigns |
|---|---|---|---|---|---|
| HappySales | Prospecting from Claude, ChatGPT or the web app | LinkedIn company search, or your own CSV | Waterfall of several data providers for email and phone; you pay only for data found | Per organization, unlimited users | Yes: LinkedIn and email sequences |
| Clay | Data and workflow platform | A marketplace of third-party data providers, plus your own sources | Waterfall across providers, plus Claygent web research | Plans with unlimited seats, metered in Actions and Data Credits | Yes: cold email through the Clay Sequencer |
| Apollo.io | Sales platform with its own database | Apollo's own people and company database | Emails and phone numbers paid with pooled credits | Plans by seat, with credits | Yes: email sequences on every account |
| Origami | AI agent that finds buyers and writes to them | Its own research across public sources, starting from your website | Verified emails and phone numbers within plan usage | Monthly plans with included usage, unlimited team members | Yes: email and social cadences |
| Spear | Signal-based outbound sent from executives' profiles | Spear's included data and monitored signals | Included in the plan, with no credits | Per profile per month | Yes: LinkedIn, email, X and Reddit sequences |
HappySales, Clay and Origami do not charge per seat, so adding a rep does not change the bill; Apollo.io charges by seat and Spear by sending profile.
Clay vs Apollo.io: which one fits prospecting
Clay and Apollo.io solve contact data in opposite ways. Clay buys data from many providers and lets a team design the workflow around it; Apollo.io sells access to its own database inside a sales platform that already includes sequences and a dialer. Clay suits teams with someone to build and maintain tables, and Apollo.io suits teams that want one ready-made tool.
The billing follows the same split. Clay plans include unlimited seats and meter Actions and Data Credits; Apollo.io prices the account by plan and seat count, and its credits reset every billing cycle without rolling over. On Clay, the pricing page states: "If an enrichment returns no result, you're not charged Data Credits or Actions."
HappySales sits between the two: it has no workflow builder like Clay and no proprietary database like Apollo.io, but it takes the company list straight from LinkedIn and runs the campaign on LinkedIn as well as email.
How HappySales replaces a Clay table for prospecting
HappySales covers the path that many teams build in Clay: target companies, the right people, their email and phone, and the first contact. In HappySales those four steps are requests made in Claude or ChatGPT through a connector, with no table to design and no provider to connect. Billing is per organization rather than per seat, and the number of users is unlimited.
The company list comes from LinkedIn's own company search. A HappySales company search filters by keywords (one word each), by a maximum of 20 locations, by a maximum of 20 industries from the 434 in LinkedIn's taxonomy and by LinkedIn's headcount ranges. LinkedIn caps every search at 1,000 companies; bigger markets are covered with several searches, cut by location or headcount. An account list from Clay or the CRM can also come in as a CSV, up to 500 companies per file.
Contacts are found inside the companies on that list. HappySales narrows people down by their exact title, function, seniority, location or a recent move to a new job, with a ceiling of 100 people per company and 10,000 in total for a search. A founder looking for Heads of Finance at software companies of 51 to 200 employees in Lisbon, for example, runs one company search and one contact search.
Enrichment in HappySales is a waterfall across several data providers, as in Clay, but without building it yourself. One run covers up to 100 contacts, only the emails and phone numbers that are found are charged, and each email is labelled deliverable, catch-all or undeliverable. Why a waterfall beats a single database is explained in our walkthrough on getting a prospect's cell number, and where enrichment sits in the process is covered in our guide to the prospecting stages.
Qualification uses your own criteria. In HappySales you define your own fields, for instance "does this company sell to hospitals?", and your AI assistant fills them in for each company or contact on the list. HappySales stores the answer without running an AI model of its own: the assistant you connect does the research.
Outreach runs on LinkedIn and email in the same sequence. On LinkedIn, a sequence opens with a connection request, with or without a note, or with a message when you are already connected; once accepted, no more than 5 follow-ups go out, and any reply ends it. A step-by-step walkthrough is in our guide to outbound campaigns from Claude or ChatGPT.
You add HappySales to Claude or ChatGPT as a connector, with an OAuth 2.1 sign-in; for a team rollout, contact HappySales.
HappySales does not do everything Clay does. It has no visual workflow builder, no AI research agent of its own, no ad audience sync and no CRM: it works before the CRM. Teams that build bespoke plays across many data sources are better served by Clay.
