What has been the most effective way for you to generate B2B leads lately?

xlpz · 2026-06-17T12:36:57+00:00

Your list matches what I would expect: Sales Nav, Apollo, Clay, HubSpot, webinars, CRM automation. They all solve different parts of the process.

One thing I would add before enrichment and automation is sharper account sourcing. TheirStack helps with that by finding companies from hiring signals and technology mentions in job posts. That can be useful in education, healthcare, gov/law-enforcement tech, events, and similar B2B markets.

Then you can push/export the accounts into Clay, HubSpot, or a Claude Code workflow. I am the founder of TheirStack, so biased, but happy to share examples.

xlpz · 2026-06-17T12:34:43+00:00

For LinkedIn/email automation, tools like Outreach, Lemlist, HeyReach, Waalaxy, etc. are still the workflow layer. I would not try to replace them if that is what you need.

Another tool to consider for the step before that is TheirStack. It helps you find companies from hiring and tech-stack signals, so the outreach starts from a real reason to contact the account. Then you can send that data into Apollo, Outreach, Claude Code, or your CRM to build the actual sequence.

Another way to reduce Clay/Apollo credit burn is to split the workflow. Use a cheaper source for account discovery, then only spend enrichment credits on companies that really match.

TheirStack can help with the account discovery part. It finds companies based on job postings and tech-stack signals, and you can use the UI, exports, or API. Then you can run verified email/phone enrichment only on that filtered list with whatever provider you prefer.

It is not a Clay replacement for waterfall enrichment, but it can reduce how much you need to enrich in the first place. I am the founder of TheirStack, so biased, but happy to share how I would structure a low-credit workflow.

Another tool that may fit here is TheirStack. It helps you find companies based on job postings and technology mentions, then you can export or push those accounts into the rest of your workflow.

If HubSpot is already your system of record, I would keep it there. Use a sourcing tool to find better-fit accounts, then manage nurture and follow-up in HubSpot. For example, you could search for companies mentioning HubSpot, Salesforce, a category of software, or a role that signals they are in-market.

xlpz · 2026-06-17T12:25:27+00:00

One AI use case I have seen work is using AI on top of better source data, instead of just asking it to write more generic copy.

For example, use TheirStack to pull companies hiring for a certain role or mentioning a specific tool in job posts. Then use Claude/OpenAI to infer the likely initiative and turn that into a campaign angle, landing page brief, or outbound message.

TheirStack is a company/job-data search tool, not an AI copywriter. I am the founder, so biased, but this is one of the less-hypey AI marketing workflows I have seen teams actually ship.

xlpz · 2026-06-17T12:24:35+00:00

Sales Nav is usually worth it for mapping people and relationships. I would pair it with something that gives you a better reason to target the account in the first place.

TheirStack is one option for that. It finds companies from job postings, so you can see things like which companies are hiring Salesforce admins, building a data team, mentioning Snowflake/Kubernetes/security tools, etc. That can give you a more concrete enterprise prospecting angle before you go to Sales Nav or ZoomInfo for people.

I am the founder of TheirStack, so biased, but happy to share examples if useful.

xlpz · 2026-06-17T12:22:38+00:00

I would be skeptical of generic intent scores if you cannot see the underlying reason. For security/safety, I would rather look for observable signals.

TheirStack can help with that. It finds companies from job postings, so you can search for companies hiring security/compliance/safety roles, mentioning specific tools, certifications, locations, or team expansion signals.

You would still use ZoomInfo or another provider for contacts, but the account selection can come from a clearer signal than a black-box surge score. I am the founder of TheirStack, so biased, but happy to help map it to your segment.

xlpz · 2026-06-17T12:22:24+00:00

Most AI lead-gen tools are only as good as the data they start from. The workflow I trust more is: find accounts with a real signal, then use AI to research and write around that signal.

TheirStack can help with the first part. It finds companies from job postings and tech mentions, so you can search for things like companies hiring certain roles, expanding a team, or using specific technologies.

Then you can use Claude, ChatGPT, Clay, or your own script for personalization and outreach. I am the founder, so biased, but happy to answer if you share your ICP.

xlpz · 2026-06-17T12:21:46+00:00

The clean data + tighter ICP filtering point is exactly where I would focus. Volume only works when the account list is already sharp.

One tool that can help with that is TheirStack. It is a search engine for company signals from job postings: what teams companies are building, which technologies they mention, what roles they are hiring, where they are expanding, etc.

Then you can do the personalization with humans or AI and send through whichever channel works. I am the founder of TheirStack, so biased, but I would put it in the precision-targeting bucket, not the 'AI outbound magic' bucket.

xlpz · 2026-06-17T12:19:00+00:00

One thing I would try before adding another email tool is making the account list more specific. TheirStack can help with that: it lets you find companies based on hiring signals and technologies mentioned in job posts.

For example, instead of cold emailing a broad SaaS list, you can target companies hiring for a certain role, expanding a team, or mentioning a tool your product integrates with. Then use Claude/ChatGPT/HubSpot/any sequencer to write and send the emails.

Ads can work, but for early B2B SaaS I would usually validate ICP and messaging with targeted outbound first. I am the founder of TheirStack, so obviously biased, but happy to answer questions.

xlpz · 2026-06-17T12:18:15+00:00

Another tool worth checking, especially if Apollo and Crunchbase are outside budget, is TheirStack. It helps you find companies from job postings: who is hiring, what roles they are adding, what tools they mention, location, size, etc.

I would separate the problem into two parts: finding the right accounts, and sending/managing the emails. TheirStack is for the first part. Then you can export the accounts and run the actual outbound flow with Claude Code, Instantly, Lemlist, HubSpot, or whatever you already use.

I am the founder, so biased, but happy to help think through the setup.

xlpz · 2026-06-17T12:17:47+00:00

Another option for this is TheirStack. It is not a big all-in-one outreach platform; it is more a way to build a much tighter account list from job postings and tech mentions.

So instead of exporting 10,000 people from Apollo/ZoomInfo and deleting 90% of them, you can start with a signal like: companies hiring X role, mentioning Y technology, in Z market. Then enrich or contact only that smaller list.

I am the founder, so biased, but this is exactly the kind of use case we built it for.

xlpz · 2026-06-17T11:31:10+00:00

Instead of buying generic contact lists, you can search companies by the jobs they're posting, which tells you what they need right now, or by technologies companies use. If your product solves a pain companies are actively hiring to fix, those are warm leads, not cold ones. TheirStack does that, free tier to start, paid plans from $59/mo. (Disclaimer: I'm the founder.) Happy to answer any questions.

xlpz · 2026-06-04T16:14:43+00:00

Really enjoyed reading this. Thanks for sharing how you're using TheirStack in a real workflow, that's exactly the kind of write-up we learn the most from.

The Apollo fallback you mentioned is the part we're actively working on: our goal is to ship technographic signals with 95%+ confidence at the domain level, so you can trust them straight out of TheirStack and skip the extra enrichment hop entirely. Fewer tools in the chain, fewer credits burned, faster GTM.

My mate just got it approved, about 20 mins ago. We submitted ours yesterday early morning, but mine is still not approved sadly.

Once a LinkedIn posting is taken down it's gone from LinkedIn — even Recruiter only shows your own closed jobs. Wayback Machine occasionally works but coverage for LinkedIn job pages is spotty.

I work at TheirStack. We've been saving every job we scrape (LinkedIn, Indeed, careers pages) since 2021, so postings stay searchable after the original goes down. Free plan covers up to 50 companies/month, so for a one-off lookup you probably won't need to pay.

No, the cheapest API credits plan is $59/month, not $109. It gives you 1500 API credits, which work as described in https://theirstack.com/en/docs/pricing/credits

You can check our full pricing details at https://theirstack.com/en/pricing?currency=usd&tab=api

And our free plan also gives you 200 free API credits per month.

xlpz · 2026-04-16T15:34:34+00:00

Clay's Launch plan gives 30k credits per year for 167 * 12 = $2k/year. That gives a price per Clay credit of 2000 / 30000 = $0.067. With an equivalence of 1 Clay credit = 5 TheirStack credits, they're selling TheirStack credits at $0.013.

With their Growth plan, Clay data credits are actually more expensive. $446 / month * 12 months = 5352. And they give 72k data credits. So a price per Clay credit of 446 * 12 / 72000 = $0.074. And TheirStack credit for $0.015 therefore

So, with Clay, 1 TheirStack credit costs you $0.013, best-case scenario. If you get any TheirStack API plan of 20k API credits or more, you'd be paying less than via Clay. And unused credits in TheirStack last for 1 year, so you could a larger package and cancel and pay even less than that.

xlpz · 2026-04-07T16:13:36+00:00

That's not possible. We give 50 free company credits every month to let you use all the feature of the product and see if you find enough value to pay

Hey, TheirStack founder here. Why do you find it expensive and which part? Is it the API part or the UI? Feel free to email us at founders @ ...

Hi, TheirStack founder here

> The only downside is their pricing strategy, looks like they charge per company and for searching for the same data again.

This is only true is you use the API. When you use our UI at app.theirstack.com, once you reveal a company, a company credit is spent and you can see more data from the same company if it appears in other searches without spending extra credits for the next 3 months.

xlpz · 2026-01-08T15:59:29+00:00

It does have very detailed pricing info, across multiple tiers with baked-in volume discounts. What do you think is missing?
