OppStreamA workbench, or an opinion
Clay gives you the parts and the freedom. OppStream gives you a position on how this should be done.
Clay is enormously capable and expects you to build the workflow: pick the sources, wire the enrichment, write the prompts, maintain it as things change. OppStream decides those things for you. That is a real trade — you lose flexibility and you stop maintaining a machine.
The difference, line by line
Not a feature checklist — what each tool is designed to do, which is the part that does not change next quarter.
OppStreamWhat it optimises for
ClayFlexibility. Whatever workflow you can specify, you can build.
OppStreamTime to value. The defaults are the product, so there is nothing to assemble.
Who builds the logic
ClayYou do — sources, enrichment waterfall, prompts, and their upkeep.
OppStreamIt ships with an opinion about what to research and what evidence is good enough.
Setup effort
ClayA build. Real work before the first useful output.
OppStreamA website and a sentence. First scored accounts arrive without configuration.
Ongoing maintenance
ClayYours. Workflows drift as sources and prompts change.
OppStreamNone. Research improves without you rewriting anything.
What happens with thin evidence
ClayWhatever your prompt tells it to do.
OppStreamIt refuses to state the claim, and leaves the field empty.
Who it suits
ClayTeams with someone who enjoys building go-to-market plumbing.
OppStreamTeams where nobody wants a second job maintaining a workflow.
What each one is built to do
Clay
- A spreadsheet-shaped workbench wired to many data providers.
- You compose the enrichment waterfall and the prompts yourself.
- Extremely flexible: if you can specify it, you can probably build it.
- The output is as good as the workflow you designed and keep current.
OppStream
- Opinionated: it decides what to research and what evidence is good enough.
- Nothing to wire. It reads your website and starts finding accounts.
- Less flexible on purpose — the defaults are the product.
- Refuses to state anything it cannot evidence, rather than leaving that to your prompt.
Which one should you choose?
Choose Clay if…
- You have someone who enjoys building and maintaining go-to-market plumbing.
- Your process is genuinely unusual and needs bespoke logic.
- You want to own the data sources and swap them yourself.
- You are running many different motions at once.
Choose OppStream if…
- Nobody on your team wants a second job maintaining a workflow.
- You want it working this afternoon rather than after a build.
- You would rather argue with a recommendation than write the logic that makes one.
- You want the tool to refuse to guess, without you having to enforce it.

Common questions
- Is OppStream a Clay alternative?
- For teams who want the outcome without building and maintaining the machine, yes. If your process is genuinely unusual and you have someone who enjoys the plumbing, Clay's flexibility is a real advantage.
- Can I customise what OppStream researches?
- You correct what it infers about your business, choose your products and set your own outreach guidance. What you do not do is wire up sources and prompts — that is the trade this page describes.
- How long does OppStream take to set up?
- Minutes. You give it your website and a sentence about what you sell, and the first researched accounts arrive without further configuration.
- What if I outgrow the defaults?
- Ask us. Where the default is genuinely wrong for a market we would rather fix the default than sell you a builder.
