TheirStack vs Sumble

TheirStack and Sumble are both powerful platforms that transform job postings into actionable sales intelligence and technographic data.

TheirStack has been collecting data since 2021, is bootstrapped and profitable with thousands of customers. We've put a big effort in building a world-class self-serve experience for people to use our App, API and webhooks in an autonomous way. Our transparent public pricing already includes big volume discounts that will let you scale as you want without having to engage in long sales process or be locked into long, expensive contracts.

Sumble is a more recent player that has raised almost $40M in venture capital, with a sales motion focused on enterprise customers. Their product is fast and capable, but smaller in data volume and organization coverage than us. Sumble has a basic pricing page and now lets you top up credits self-serve by card up to 25,000 credits; beyond that, and for team-wide packages, the per-credit rate is not published and you have to talk to sales.

Feature comparison

Pricing Drill-down

1. Transparency and Scaling: No Sales Calls Required

TheirStack's public pricing shows exactly what you'll pay at every level. As you scale, the cost per credit drops dramatically—down to $0.0015 per credit on our $1,500 plan. You can scale from 1,500 to 1,000,000 credits autonomously. We also offer one-time credit purchases — buy a credit pack without any subscription, and use it within 12 months.

Sumble's Pro plan (check their pricing here) provides 9900 credits for $99/month per user. You can buy more credits self-serve by card up to 25,000; above that the rate is not published and you need to contact sales for an Enterprise plan.

Conclusion: TheirStack wins on pricing transparency and self-serve scaling.

2. Job and Organization Costs (API Credits)

At TheirStack, a job costs exactly 1 API credit. An organization lookup costs exactly 3 API credits.

TheirStack also have webhooks, which is the equivalent of Sumble's signals. The cost of getting data via webhooks on TheirStack is the same as via API (1 job = 1 API credit, 1 company = 3 API credits). Sumble charges 1 credit per signal returned.

Sumble bills jobs per field, not per job: 1 base credit, plus 1 credit for every paid attribute you ask for, plus 1 credit per related person. Only the job title and identifiers are free. So on their 9,900-credit Pro plan, the same query costs anywhere from 1 to about 10 credits per job depending on how much of the record you need.

The closest plan TheirStack has in price offers 5k API credits for $100/month, and a credit returns the whole job record — title, description, location, salary, seniority, the company and its enrichment — with no per-field surcharge.

For the same monthly spend:

• Title-only: Sumble returns ~9,900 jobs, TheirStack ~5,000. Sumble is cheaper when a job title and an ID are all you need.
• Full record: Sumble's ~10-credit job puts the same 9,900 credits at roughly 1,000 fully-populated jobs, against TheirStack's 5,000.

Conclusion: Sumble is cheaper for shallow, title-only extraction. TheirStack is cheaper as soon as you need the actual contents of the posting, and the price does not change with the field set — which makes it possible to budget a pipeline in advance.

3. Technographics cost: Fixed vs. Variable

This is where the difference is most extreme.

• TheirStack: A single lookup (3 API credits) returns every technology we have ever identified for an organization, along with confidence levels and granular metrics. The price is the same whether the company runs 3 technologies or 300.
• Sumble: An organization costs 1 base credit plus 1 per paid attribute, plus the number of metrics requested for each technology. Their own worked example — 3 attributes and 1 technology with 2 metrics — comes to 6 credits (~$0.06). Requesting a technology category with exploded granularity multiplies that per technology returned, so the cost of a full stack scales with the size of the stack.

The practical difference: with TheirStack you can price a technographic enrichment run before you start, because the unit is the company. With Sumble the same run costs a different amount for every company, and the companies with the richest stacks — usually the ones you most want — are the expensive ones.

Conclusion: TheirStack wins on technographics cost predictability, and on cost outright for companies with large technology stacks.

4. UI Pagination and Search Limits

Sumble's plans limit how deep into the result pages you can go. Their API page size depends on what you ask for—up to 1,000 jobs in list mode, but 200 in search mode or when you request descriptions, and 25 when you request related people—and every query sits under a hard offset ceiling of 10,000 records. TheirStack is fully usage-based and provides infinite pagination in the UI—as long as you have the credits to view the data, you can access it.

Conclusion: TheirStack wins on UI pagination and search limits.

Data Volume and Freshness

When it comes to the sheer volume of data and how quickly it's delivered, TheirStack consistently outperforms Sumble across both jobs and organization profiles.

Job Volume: 4x More Coverage

TheirStack identifies over 2.4M jobs per week, which is 10M jobs in the last 30 days. Click here to open this search on TheirStack to double-check it yourself.

Sumble only surfaces approximately 1,800,000 jobs per month. This gives TheirStack over 4x more volume than Sumble. Double-check by going to this same search in Sumble.

Conclusion: TheirStack wins on job volume.

Job searches filtering by technology

Both TheirStack and Submle identify technology usage from mentions in job posts. So both of them should be great at being able to surface jobs that mention specific technologies. Let's see how true that is.

For a search like "Python jobs posted in the last 30 days", TheirStack identifies over 224,000 jobs, as seen in the folllowing screenshot. Open this search on TheirStack

On the other hand, Sumble only yields approximately 125,000 jobs for the very same search. Open this search on Sumble

Real-time Freshness

TheirStack processes and exposes jobs in our API and UI within minutes of them being posted online.

Sumble's documentation states that job posts are updated multiple times a day, and that its people, organization, technology, trends and signals data updates daily. The screenshot above was captured when their published cadence was a 24-hour refresh.

Conclusion: TheirStack wins on data freshness.

Database Scale: 9.5M vs 2.6M Organizations

• TheirStack: Detailed data on 9.5 million organizations.

• Sumble: Data on approximately 2.6 million organizations (TechCrunch, October 2025 — Sumble's own docs no longer publish a figure).

TheirStack has 3.5x more organizations in its catalog.

Conclusion: TheirStack wins on organization volume.

Data Depth and Feature Nuances

To provide an objective comparison, it's important to recognize where each platform focuses its engineering efforts. While TheirStack prioritizes the breadth and depth of job data and technographics, Sumble has invested more heavily in the "Person" and "Team" layers of sales intelligence.

Person-Level Intelligence

Sumble includes person-level data, which allows them to offer signals that TheirStack currently does not. For example, they can track when a company increases headcount in a specific area by monitoring changes in LinkedIn profiles.

If your workflow requires identifying the specific individuals currently at a company or seeing headcount trends based on existing employees, Sumble has a clear advantage here. TheirStack focuses exclusively on the "Organization" and "Job Posting" level—we tell you who they want to hire, not who they already have.

Conclusion: Sumble wins on person-level intelligence.

Team and Department Mapping

Sumble also attempts to identify and map specific teams within a company. This can be useful for seeing how an organization is structured internally. TheirStack provides granular firmographics and technographics for the organization as a whole, but we do not currently provide a structured breakdown of internal departments or teams.

Conclusion: Sumble wins on team and department mapping.

Job Title Normalization

Sumble uses machine learning to normalize job titles, which can help group similar roles together (e.g., "Software Engineer", "SWE", "Software Developer" might all map to a standardized title). TheirStack does not currently perform job title normalization—we return job titles as they appear in the original job postings.

Conclusion: Sumble wins on job title normalization.

Technology Inference: "Used" vs "Mentioned"

Sumble attempts to infer which technologies are actively used versus which are just mentioned as nice-to-haves in job descriptions. They label technologies as either TECH USED or TECH MENTIONED to help users understand what's required versus what's optional.

However, this inference is very unreliable and fails at basic logical relationships. For example, Sumble may mark a JavaScript framework like D3 or React as TECH USED while simultaneously marking JavaScript itself as only TECH MENTIONED. This is logically inconsistent—if a JavaScript framework is used, then JavaScript knowledge is absolutely required as well. The system fails to recognize these fundamental dependencies between technologies.

TheirStack takes a different approach: we identify all technologies mentioned in job descriptions without attempting to infer usage versus mention. We focus on doing one thing well—accurately identifying what technologies appear in job postings—rather than trying to do more and doing it inconsistently.

Conclusion: TheirStack wins on technology inference reliability.

Technology Catalog Quality

Sumble's technology catalog is derived directly from job descriptions using a Named Entity Recognition (NER) model. While this approach can capture a wide range of terms, it yields many entries that aren't actually technologies. A very large percentage of Sumble's catalog consists of "dirty" technologies—phrases like "Python Data Analytics", "Python backend", "Python software development", "Data visualization using Python", and "API/Python" that are descriptive phrases or job functions rather than actual technology names.

TheirStack's technology catalog is smaller and cleaner because it doesn't contain this fluff. We focus on identifying actual technologies mentioned in job postings, not extracting every phrase that happens to contain a technology keyword. This results in a more accurate, usable catalog for filtering and analysis.

Conclusion: TheirStack wins on technology catalog quality.

Organization Intelligence and Parent-Subsidiary Relationships

Founded by world-class Machine Learning experts, Sumble does a much better job at organization intelligence, particularly in identifying and mapping hierarchical organizational structures. They can accurately determine whether an organization has subsidiaries or is an independent company, and they effectively tie together organizations under the same parent organization.

For example, Sumble can display complex hierarchies like "U.S. Government" → "US Department of Energy" → "Lawrence Berkeley National Laboratory" → "Cyclotron" with clear parent-child relationships. This hierarchical view helps users understand organizational structures and relationships at a glance.

TheirStack treats organizations more independently and does not currently provide the same level of parent-subsidiary relationship mapping or hierarchical organization intelligence.

Conclusion: Sumble wins on organization intelligence and parent-subsidiary relationships.

API Documentation and Filtering Capabilities

Developer Experience: Clear Documentation vs. Limited Docs

TheirStack's Job Search API documentation is comprehensive, self-serve, and includes examples for every parameter. You can test endpoints directly in the browser.

Sumble's API documentation is more limited. While functional, it lacks the depth and clarity needed for complex integrations. Understanding parameter usage often requires trial and error or reaching out to support.

Sumble offers an "advanced query" option that allows filtering by fields like job_function or hiring_period, but these parameters are not documented in their public API reference. This undocumented functionality requires developers to discover features through experimentation or support conversations.

Filter Depth: 40+ vs. 7 Filters

This is where the gap becomes most apparent for developers building sophisticated search workflows.

TheirStack's Job Search API offers 40+ filters across multiple categories:

• Job-level filters: Title (with regex support), description patterns, location patterns, salary ranges, seniority, remote options, posted date ranges, and more.
• Company-level filters: Industry, size, country, revenue, funding, URL patterns, LinkedIn URL, and more.
• Technology filters: Filter by technologies mentioned in job descriptions.
• Advanced features: Regex support for many text fields, exclusion filters, and complex boolean logic.

Sumble's Jobs API offers a narrower set, documented as an advanced query plus organization targeting:

• Organization filters (up to 1,000 organization IDs, or a saved organization list)
• Technology and technology category filters
• Job function filters (Sumble resolves a job title to a normalized function and level)
• Country filters
• Hiring-period filters

Sumble targets roles through its normalized job functions rather than by matching the posting's own title text, so a search for an exact title, a phrase inside the job description, or a regex is not available. That normalization is a genuine strength when you want every variant of "Software Engineer" in one bucket, and a limitation when you need the specific wording a company used.

If you need to build sophisticated search workflows—like finding "Python jobs in New York posted in the last 7 days for companies with 50-200 employees"—TheirStack's extensive filtering capabilities support this use case.

Conclusion: TheirStack wins on developer experience.

Quick Decision Guide

Summary

TheirStack offers predictable per-record pricing that does not change with the field set, higher job volume (10M jobs in the last 30 days vs 1.8M per month), real-time freshness (minutes rather than a refresh several times a day), 40+ API filters including exact-title and description matching, reliable technology identification, a clean technology catalog, and a larger organization database (9.5M vs 2.6M). Sumble provides person-level intelligence, team mapping, organization intelligence with parent-subsidiary relationships and rollup counts, job title normalization, closed-company detection, funding data, an MCP server for AI agents, and signals based on new hires or headcount growth that TheirStack does not currently support. Sumble is also cheaper per job if a title and an identifier are all you need.
