TheirStack

TheirStack provides job posting, company, and technographic data for sales intelligence, market research, and recruiting workflows.

Verdict

TheirStack surfaces company intelligence — firmographics, tech stacks, funding rounds, and job postings — so your team can research prospects, qualify leads, or track hiring signals without leaving Switchy. @mention it to search by industry, revenue band, or installed technology, then pull full profiles that cost 3 API credits each. Sales and partnerships teams get the most mileage. Free accounts hit a 100-company daily cap; paid tiers lift that ceiling. The MCP won't create lists or modify saved searches — it's read-only access to TheirStack's catalog and your team's credit balance.

Common use cases

  • Qualify inbound leads by tech stack
  • Build account lists for outbound campaigns
  • Monitor competitor hiring activity
  • Research partnership targets by industry
  • Track funding rounds in target segments

Setup

Setup guide

  1. 11. In Switchy, open Settings → Integrations and click Connect next to TheirStack. 2. You'll be prompted to paste a TheirStack API key; generate one by logging into your TheirStack dashboard, navigating to API Settings, and clicking Create Key. 3. Copy the key and paste it into Switchy's dialog, then click Authorize. 4. Switchy confirms the connection and displays your current credit balance. 5. Open any Project and type '@TheirStack check my credit balance' to verify the integration works. 6. To run a company search, write '@TheirStack find SaaS companies in healthcare with 50–200 employees' and the MCP will return a paginated list with firmographic details. 7. Remember each company record costs 3 API credits, so scope your searches to stay within your daily allowance.

What teammates see: by default, memories from TheirStack are scoped to the Project (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

Example outputs

Illustrative - representative of the model's voice and quality, not literal recordings.

Prompt

@TheirStack search for Series B SaaS companies in Austin using React and PostgreSQL, then summarize their funding stages and employee counts.

Output

Found 14 companies matching your criteria. Example results include a fintech platform with 87 employees and $23M Series B raised in Q2 2024, a marketing automation tool with 52 employees and $18M Series B from late 2023, and a developer tooling startup with 41 employees and $15M Series B closed this quarter. All three use React frontends with PostgreSQL backends. The median employee count across the set is 58, and total funding ranges from $15M to $31M. This search consumed 42 API credits (14 companies × 3 credits each).

Notes

This example highlights TheirStack's firmographic and technology filtering—ideal for prospecting or competitive analysis. Each returned company costs 3 API credits, so a broad search can quickly exhaust a free account's daily allowance. Check your credit balance with the Get Credit Balance tool before running large queries.

Prompt

@TheirStack show me my saved searches and credit consumption over the last 7 days so I can see which queries are burning through our quota.

Output

You have 6 saved searches: 'Enterprise SaaS – AWS stack' (last run 2 days ago), 'Seed-stage AI companies' (last run 5 days ago), 'Healthcare tech – HIPAA compliance' (never run), and three archived searches. Over the past 7 days, your team consumed 1,847 API credits—peak usage was Monday (412 credits) when the 'Enterprise SaaS' search returned 137 companies. UI credits consumed: 89, mostly from manual profile views. Your current balance is 3,153 API credits, expiring in 22 days.

Notes

This read-heavy example demonstrates credit monitoring and saved-search inventory—critical for teams managing usage across multiple users. The tool returns cumulative totals and daily breakdowns, helping you identify expensive queries before they exhaust your quota. No credits are consumed by listing saved searches or checking balances.

Prompt

@TheirStack find job postings from the last 30 days at companies using Kubernetes, filter for senior engineering roles in the Bay Area, and draft an outreach email template.

Output

Found 89 job postings matching your criteria. Representative roles include a Senior Platform Engineer at a Series C observability startup (posted 4 days ago, $180k–$240k range), a Staff SRE at a public cloud security vendor (posted 11 days ago, $200k–$260k), and a Principal Engineer at a fintech unicorn (posted 18 days ago, no salary disclosed). All three companies run production Kubernetes clusters and are headquartered in San Francisco or Palo Alto. Draft email: 'Hi [Name], I noticed [Company] is hiring for [Role]—your Kubernetes-native architecture caught my attention. I've helped similar-stage companies...' This search consumed 267 API credits (89 jobs × 3 credits).

Notes

This synthesis example pairs TheirStack's job-search tool with AI reasoning to generate actionable outreach. Job searches require either a posting-date or company filter; omitting both will fail. Like company searches, each result costs 3 API credits, so narrow your filters (seniority, location, technology) to avoid quota overruns on exploratory queries.

Use-case deep-dives

Outbound list building for seed-stage sales

When TheirStack beats manual LinkedIn scraping for prospecting

A 3-person sales team at a dev-tools startup needs 200 qualified leads per quarter—companies running specific tech stacks (React + AWS Lambda) with 10-50 employees and recent Series A funding. TheirStack's Search Companies tool delivers this in one query, costing 600 API credits (200 companies × 3 credits each), versus 8-12 hours of manual research per rep. The credit budget matters: free accounts hit limits fast, so this works when you're already paying for TheirStack or can justify the paid tier based on time saved. If your ICP changes weekly or you need real-time contact emails (not just company matches), you'll still need enrichment tools downstream. For stable ICPs and firmographic targeting, TheirStack turns list-building from a weekly chore into a 5-minute Switchy prompt.

Competitive intelligence monitoring

Track hiring signals without a dedicated research analyst

A 6-person product team at a B2B SaaS company wants early warnings when competitors staff up in specific areas—new ML engineers at rival X, customer-success hires at rival Y. TheirStack's Search Jobs tool filters by company, title, and posting date, so an agent can run weekly checks and surface new roles in a Slack digest. This scenario lives or dies on whether your competitors post publicly (many don't) and whether you care about historical trends (the tool supports date ranges). If you're tracking 3-5 known competitors and they hire via LinkedIn or Greenhouse, this replaces a manual ritual. If you need deeper org-chart mapping or private hiring intel, you're outside TheirStack's scope. For lightweight competitive hiring signals, it's a 10-credit-per-week habit that keeps the team informed without a research hire.

Partnership pipeline qualification

Filter integration partners by actual customer overlap

A 4-person partnerships team at a fintech platform evaluates 40 inbound integration requests per quarter but only has bandwidth for 6. TheirStack's technology and funding filters let an agent score each candidate: do they serve Series B+ companies, do their customers use Stripe and Plaid (our stack), do they have 500+ employees (integration-support threshold)? The List Company Lists and Search Companies tools surface overlap in under a minute per candidate, versus 20 minutes of manual research. The boundary: if your partnership criteria hinge on revenue, customer count, or private attributes TheirStack doesn't index, you'll still need manual diligence. For tech-stack and firmographic pre-qualification, this MCP turns a quarterly spreadsheet slog into a Switchy workflow that ranks candidates before the first call.

Frequently asked

What does the TheirStack MCP let me do in Switchy?

It connects your team's TheirStack account so AI agents can search companies by technology stack, funding, or industry, pull job postings, and check your credit balance before running expensive queries. Agents can read your saved searches and company lists but won't modify them or create new ones.

Do I need a paid TheirStack account to use this MCP?

You need any TheirStack account with an API key—free accounts work but have tighter credit limits. Each company search result costs 3 API credits, so agents will check your balance first and warn you if a query would exhaust your allowance. Job and industry searches consume no credits.

Can the MCP create or update company lists in TheirStack?

No. It only reads existing lists and saved searches. If an agent needs to segment prospects or tag companies, you'll still open TheirStack's UI or use their full API directly. The MCP is read-only by design to prevent accidental bulk changes.

Why use this instead of exporting CSV files from TheirStack?

Agents can filter on the fly—"find Series A SaaS companies using Postgres in EMEA"—without you manually exporting, cleaning, and uploading CSVs. They also respect your live credit balance and stop before burning through your quota, which a static export can't do.

Who on my team should connect the TheirStack API key?

Whoever owns your TheirStack subscription and understands your credit budget. That person's API key determines which datasets and saved searches agents can see, and all queries count against your shared team quota—not per Switchy seat.
