Odyn vs. Clay: build your own prospecting machine, or use one that already exists?

What Clay does well

Clay describes itself as the tool for people who build their own go-to-market systems ("GTM engineers build on Clay"), and claims more than 500,000 teams. It offers data providers (150 according to one page of its site, 200 according to another) queried one after another until one returns the answer, AI research agents (Claygent) that read the web to qualify a company, and "signals": topic intent, new hires, promotions, job changes, news and fundraising, job postings, web intent.

The job postings signal watches for target companies opening new roles. It starts from a list of companies (a web domain or a LinkedIn company page), you set how often it checks, from quarterly to daily (monthly by default), and it uses credits per result or per company checked; Clay shows an estimate before you launch. Another action in its catalog pulls a company's open jobs from Apollo's data, provided you bring your own Apollo account.

Clay is clear about what it is: infrastructure, not a finished prospecting application. A recruiter at your firm who has already built tables of this kind can get from it whatever they want.

Two meters, and other tools around it

Clay's price comes in two parts because there are two meters. Actions measure work done, data credits pay for information bought. Each is bought in tiers. The Launch plan at its lowest adds $54 of actions and $113 of data credits: $167 a month on annual billing, or $185 billed monthly. Growth starts at $446 on annual billing and $495 monthly. Clay says data credits start at $0.05 each and actions at under a cent. Extra credits cost 30% more than the base rate, unused actions do not roll over, and the page describes two different rollover rules for credits. The free plan gives 100 data credits and 500 actions a month, tables capped at 200 rows, and no phone number lookups.

Two functions sit outside Clay, according to its pages. For email, its documentation says Clay "doesn't replace your email sequencer" and pushes messages to Smartlead, Instantly, Salesloft, Outreach or HubSpot, although the pricing page lists a Clay sequencer from the Growth plan. For LinkedIn, the pages we read describe no sending of invitations or messages; they talk about syncing audiences with ad campaigns. For that channel you add a dedicated tool with its own subscription.

What you would build in Clay to prospect companies that are hiring

To do what Odyn does, a system built on Clay has to link at least these pieces:

1. a list of companies to watch, since the job postings signal only works on companies you give it;
2. a sorting step for postings, to set aside those placed by other agencies for their own clients, or of no interest to you;
3. a search for the right decision-maker at each company, and a check of their email;
4. writing instructions for the AI, tested until the messages sound like you;
5. an email sending tool, a LinkedIn tool, and someone watching their settings;
6. a way to track replies, so you know who to follow up and who to leave alone.

None of it is out of reach. But it is a project, with credit meters to watch, and it depends on the person who built it.

What Odyn changes

Odyn starts from published job postings, with no list supplied. It finds the companies hiring in the recruiter's target (roles, locations, industry) and sorts out the postings worth a recruiter's message. It finds the decision-maker for each hire, writes a message based on the posting in the recruiter's style, sends it from the recruiter's own email address and LinkedIn account, follows up with restraint, and stops when the decision-maker replies. For the first three business days the recruiter reviews and approves every message.

A word on signals, which Clay multiplies. In our data, the fashionable buying signals (a funding round, a new executive, a public contract won) predicted nothing clear about replies, while the job posting itself did; see business development for a recruitment firm. Those observations come from mostly French postings between June and October 2026. A tool that offers seven families of signals does not tell you which ones matter to a recruiting firm. Odyn picked one.

The subscription is €290 a month per consultant, excluding VAT, with no long-term commitment, for 450 decision-makers contacted per month, by email and LinkedIn. Pricing lists what is included, and the AI prospecting agent explains what an agent does compared with a tool. Odyn started in France and its track record is on French postings, so if you recruit in the US or the UK, ask during the 15-minute demo how it covers your market.

Clay and Odyn side by side

When Clay is the better choice

Clay wins as soon as your prospecting goes beyond companies that are hiring. A firm that targets a precise list of accounts (every manufacturer in one industrial county, say), wants to combine data sources or enrich its CRM, will find in Clay a flexibility an agent does not have. It is also the right choice if you sell several things, recruiting and something else, with different pitches.

When Odyn fits better

Odyn fits when you want the prospecting done, not the workshop. An independent headhunter or a three-person firm has no time to wire six pieces together and no wish to watch credit meters. They want hiring managers to receive messages and the replies to come back. What remains yours is describing your target and reviewing messages in the first days. The other possible choices are compared in the comparison index.
