--- title: Best Coresignal Alternatives in 2026 description: Exploring alternatives to Coresignal for job data and company intelligence? Compare TheirStack, PredictLeads, and other providers to find the best fit for your data needs. url: https://theirstack.com/en/alternatives/coresignal-alternatives --- Coresignal is a B2B data infrastructure provider known for its LinkedIn-derived datasets of companies, employees, and job postings. While it offers rich people data, many teams find its LinkedIn-only job source, lack of deduplication, high per-record costs, and 6-hour update lag limiting. If you're evaluating Coresignal alternatives, this guide compares the best options in 2026. ## Quick Comparison | Tool | Starting Price | Free Tier | Category | Best For | | --- | --- | --- | --- | --- | | [![TheirStack logo](/static/generated/theirstack-logo-sm.webp)**TheirStack**](https://theirstack.com) | Free / $59/mo (one-time purchases available) | ✅ Yes | Job Data + Technographics | Intent-driven prospecting and enrichment | | [![PredictLeads logo](/static/images/competitors/predictleads.svg)**PredictLeads**](/en/comparisons/theirstack-vs-predictleads) | Free (100 requests/mo) | ✅ Yes | Job Data + Technographics | Multi-signal company intelligence beyond just jobs | | [![Sumble logo](/static/images/competitors/sumble.png)**Sumble**](/en/comparisons/theirstack-vs-sumble) | $99/mo | ❌ No | Job Data + Technographics | Person-level sales intelligence and team mapping | | [![Hirebase logo](/static/images/competitors/hirebase.png)**Hirebase**](https://hirebase.org) | Free / $79/mo (exports from $0.02/job) | ✅ Yes | Job Data + Technographics | Fresh job data from career pages with a simple API | ## Why Look for Coresignal Alternatives? #### LinkedIn-only source Misses jobs posted only on Indeed, Glassdoor, or company career pages. #### 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 ![TheirStack logo](/static/generated/theirstack-logo-sm.webp)1. TheirStackJob Data + Technographics Job-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 - ✓Global coverage: 203M+ job postings analyzed from 195 countries, sourced from 336k+ sources - ✓Real-time updates every minute — catches new technology adoptions as soon as companies post jobs - ✓Built-in deduplication across all 336k+ sources — the same job posted on multiple platforms counts once, saving credits and eliminating noise - ✓Single fast API with 40+ filters, webhooks, and sub-second response times - ✓Both UI and API — explore data interactively at app.theirstack.com or integrate programmatically, no engineering resources required to get started - ✓Official MCP server for AI-native workflows — query technographic and job data directly from Claude, Cursor, or any MCP-compatible agent - ✓Bulk datasets available for warehouse ingestion — download or schedule delivery of full data exports - ✓Self-serve transparent pricing starting free, with plans from $59/mo and one-time purchases available — no subscription required #### 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. **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. **Pricing:** Free / $59/mo (one-time purchases available) (free tier available)[Visit TheirStack →](https://theirstack.com) ![PredictLeads logo](/static/images/competitors/predictleads.svg)2. PredictLeadsJob Data + Technographics B2B 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. **Pricing:** Free (100 requests/mo) (free tier available)[TheirStack vs PredictLeads →](/en/comparisons/theirstack-vs-predictleads) ![Sumble logo](/static/images/competitors/sumble.png)3. SumbleJob Data + Technographics AI-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 - ✓Combines job posts with LinkedIn-derived signals - ✓ML-based title normalization grouping similar roles - ✓Curated signal alerts with Slack integration - ✓Find related hiring contacts for any job posting via the /jobs/find-related-people endpoint #### Considerations - ℹSmaller volume — ~1.8M jobs/month vs millions from leading providers. Up to 24h freshness lag. - ℹLimited API filters — the Jobs /find endpoint exposes only 4 filters (technologies, technology categories, countries, since date), compared to 40+ from alternatives. This makes it difficult to create targeted queries combining multiple criteria like industry, company size, and geography. - ℹLow rate limit — 10 requests per second across all endpoints, which can bottleneck high-volume integrations or parallel data pipelines. - ℹSmall result pages — maximum 100 results per request with a hard offset cap of 10,000, making it impractical to paginate through large result sets. - ℹPro plan caps signals at 20 per day and 9,900 credits per month — enterprise plan required for any meaningful scale. - ℹNo SDK or client library — all integrations require raw HTTP calls with no official wrappers for Python, JavaScript, or other languages. - ℹJSON-only responses — no CSV or other format options from the API, requiring custom transformation for analytics workflows. **Why choose Sumble:** Choose Sumble when you need person-level sales intelligence with org charts and team mapping capabilities. **Pricing:** $99/mo[TheirStack vs Sumble →](/en/comparisons/theirstack-vs-sumble) ![Hirebase logo](/static/images/competitors/hirebase.png)4. HirebaseJob Data + Technographics Real-time job market intelligence platform Hirebase is a newer job data provider focusing on real-time job market intelligence with global coverage and a modern API design. #### Strengths - ✓2M+ live job postings scraped directly from company career pages, updated within 24 hours - ✓AI-powered spam filtering removes ~60% of expired or fake listings before they reach the API - ✓DeepSearch semantic vector search (POST /v2/jobs/vsearch) finds roles by meaning, not just keywords - ✓Simple API key auth with no OAuth complexity — single x-api-key header for all endpoints - ✓One-time export purchases available (CSV/JSON) from $0.02/job with no subscription required - ✓Two search modes — keyword search (POST /v2/jobs/search) and semantic DeepSearch (POST /v2/jobs/vsearch) for natural-language job discovery - ✓Simple API key authentication with no OAuth flow — all requests use a single x-api-key header - ✓Free tier with 10 API calls/day to evaluate before committing to a paid plan #### Considerations - ℹSmaller scale — 2M+ live jobs from 33,000+ companies vs providers aggregating from 50+ sources with 100M+ total jobs. Coverage gaps are likely in non-US markets and niche industries. - ℹMinimal company-level filters — Job search only accepts company\_name, company\_slug, and company\_keywords. No filtering by industry, company size, funding stage, or technology stack — limiting its usefulness for targeted prospecting. - ℹNo technographic detection — Hirebase provides raw job postings but does not extract, normalize, or map technologies to companies. Teams needing tech stack intelligence need a separate provider. - ℹ24-hour update cycle — Data freshness is within 24 hours, compared to near-real-time (minutes) from alternatives. For time-sensitive sales outreach triggered by new job postings, this lag can matter. - ℹLimited company filters — Only company\_name, company\_slug, and company\_keywords accepted. Cannot filter by industry, company size, revenue, funding, or technology stack — requiring post-processing for targeted prospecting workflows. - ℹNo webhooks or push notifications — API is pull-only, so teams must poll for new results rather than receiving real-time alerts when matching jobs appear. **Why choose Hirebase:** Choose Hirebase when you want a simple, affordable API focused on fresh job listings scraped directly from company career pages. **Pricing:** Free / $79/mo (exports from $0.02/job) (free tier available)[Visit Hirebase →](https://hirebase.org) ## Frequently Asked Questions #### What is the cheapest Coresignal alternative for job data?
