Why Look for Coresignal Alternatives?
LinkedIn-only job source
Coresignal sources its job data primarily from LinkedIn, which means it misses postings from company career pages, niche job boards, and ATS platforms. Providers that aggregate from 16,000+ sources capture significantly more jobs — including positions that companies post only on their own careers page and never syndicate to LinkedIn.
No deduplication and high costs
Coresignal doesn't deduplicate job listings across sources, which means the same job posted on multiple platforms appears as separate records — inflating your costs. At $294 for 1,500 jobs up to $7,000 for 1M jobs, it's 3-8x more expensive per job record than alternatives that include deduplication.
Slow update cycle
Coresignal's data updates every 6 hours, compared to near-real-time (minutes) updates from alternatives. For teams that need to act quickly on new job postings — like sales teams reaching out to companies that just started hiring for a specific role — this lag can mean missing the window of opportunity.
Limited API and no UI
Coresignal's API requires a 2-endpoint flow (search then fetch) with credits that reset monthly without rollover. There's no user interface for exploration or ad-hoc queries. Teams that want both API access and a UI for interactive research need to look at alternatives that offer both.
Top Coresignal Alternatives in 2026
1. TheirStackJob Data + TechnographicsJob-based technographic and company intelligence platform
TheirStack takes a unique approach to technographic data by analyzing millions of job postings worldwide. Instead of only scanning websites for frontend technologies, it reveals what technologies companies are actively hiring for, implementing, and expanding. This means you get buying intent signals alongside comprehensive tech stack data — including backend technologies that website scanners miss entirely.
Strengths
- ✓Detects backend and internal technologies (databases, DevOps, ERPs) from job postings — not just web-facing tech
- ✓Hiring signals act as buying intent — know what companies are investing in, not just using
- ✓Single fast API with 40+ filters, webhooks, and sub-second response times
- ✓Self-serve transparent pricing starting free, with plans from $59/mo
Considerations
- ℹTechnology detection relies on active hiring — companies not posting jobs may have less coverage — TheirStack's detection method depends on companies publishing job postings that mention technologies. Companies in hiring freezes or very small teams that rarely post jobs may have less coverage compared to website scanning approaches.
- ℹNewer methodology with job-based historical data starting from 2021 — While website scanning tools like BuiltWith have decades of historical data, TheirStack's job-based approach has data from 2021 onwards. For teams that need long-term historical technology adoption trends, complementing with a website scanner may be valuable.
Why choose TheirStack: Choose TheirStack when you want intent-driven technographic data that covers the full tech stack — including backend tools that website scanners miss — at a fraction of enterprise pricing.
2. PredictLeadsJob Data + TechnographicsB2B company intelligence API with structured business signals
PredictLeads is a B2B company intelligence API offering structured signals like hiring data, customer wins, and product launches from 100M+ companies. While its breadth of signal types is appealing, many teams find its limited job filtering (6 filters), per-company API architecture, and incomplete documentation frustrating for job data use cases.
Strengths
- ✓Broader signal types: hiring, customer wins, product launches, GitHub activity
- ✓Historical data going back to 2016 for trend analysis
- ✓Coverage across 100M+ companies from 19M+ sources
- ✓Free tier with 100 API requests/month for evaluation
Considerations
- ℹVery limited job filtering — PredictLeads offers only 6 job filters and doesn't support filtering by job title, description, or location. For teams that need to find companies hiring for specific roles ("Senior Data Engineer in the US using Snowflake"), this limitation makes it nearly unusable for targeted prospecting. Alternatives offer 30-40+ filters for precise targeting.
- ℹPer-company API architecture — PredictLeads requires you to make API calls for individual companies — you can't search across all companies at once. This means you need to already know which companies you want to research, making it unsuitable for discovery and prospecting workflows where the goal is to find new companies matching your criteria.
- ℹIncomplete documentation — PredictLeads' API documentation has gaps and can be unclear, making integration more difficult than it needs to be. Developer experience matters when you're building production workflows, and alternatives with comprehensive docs, code examples, and developer support can save significant implementation time.
- ℹJob data is just one of many signals — While PredictLeads covers multiple signal types (hiring, news, customer wins), this breadth means job data isn't its core focus. If job postings and hiring signals are your primary use case, dedicated job intelligence platforms offer significantly deeper functionality, better filtering, and more comprehensive job coverage.
Why choose PredictLeads: Choose PredictLeads when you need diverse company signals beyond job postings, like customer wins and product launches.
3. SumbleJob Data + TechnographicsAI-powered sales intelligence from job postings and LinkedIn
Sumble is an AI-powered sales intelligence platform built by Kaggle founders, offering person-level data, team mapping, and organizational hierarchy from job postings and LinkedIn profiles. While its people-focused approach is unique, many teams find its smaller company coverage (2.7M vs 9.5M+), 24-hour data lag, and limited API filters constraining.
Strengths
- ✓Person-level data with team and department mapping
- ✓Organizational hierarchy visualization
- ✓ML-based title normalization for accurate role matching
- ✓Built by Kaggle founders with strong ML expertise
Considerations
- ℹSmaller company and job coverage — Sumble covers approximately 2.7M companies and processes 4x fewer job postings than leading alternatives. This means significant gaps in coverage — especially for smaller companies, international markets, and niche industries. If your ideal customer profile includes companies outside the top enterprise segment, you may find many missing from Sumble's database.
- ℹ24-hour data lag — Sumble's data updates with up to a 24-hour lag, compared to near-real-time (minutes) from alternatives. For sales teams trying to be first to reach out to a company that just posted a relevant job, this delay can mean losing the competitive advantage that fresh data provides.
- ℹLimited API filters — Sumble offers only 7 API filters, compared to 40+ from alternatives. This makes it difficult to create targeted queries that combine multiple criteria — like finding companies in a specific industry, of a certain size, hiring for a particular technology, in a given geography. More filters mean more precise targeting and less noise in results.
- ℹOpaque enterprise pricing — Sumble's Pro plan starts at $99/month, but quickly moves to "talk to sales" for higher tiers. Without transparent pricing, it's hard to plan budgets or compare costs across providers. Alternatives with self-serve, usage-based pricing let you scale predictably without surprise costs.
Why choose Sumble: Choose Sumble when you need person-level sales intelligence with org charts and team mapping capabilities.
