# TechLeads > TechLeads (https://techleads.fyi) is a B2B technographics and lead-generation platform. We detect technologies used on 450M+ websites, build filterable lead lists, estimate conservative SaaS technology spend, and expose data through a web dashboard, public pages, REST APIs, and a remote MCP server for AI assistants. ## What we do TechLeads helps sales, marketing, and growth teams find companies by **technology stack** — similar in spirit to BuiltWith or Wappalyzer, with stronger **list building**, **exports**, and **API-first** workflows. Core capabilities: - **Website technology lookup** — CMS, ecommerce, analytics, CDNs, payments, marketing automation, frameworks, and 11,000+ searchable technologies. - **Technology spend estimate (USD)** — conservative monthly/annual SaaS spend per domain (aggregate only; never per-tool pricing exposed to customers). - **Lead list search** — filter 450M+ domains by technologies, keywords, TLDs, country, industry, exclusions; preview in dashboard; export CSV. - **Contact enrichment** — business emails, phones, social links where available (compliance-aware). - **Bulk domain lookup** — upload up to 10,000 domains; async jobs with CSV download. - **Alerts & monitoring** — email when tracked domains change technologies. - **Chrome extension** — on-page technology detection while browsing. ## Pricing Full details: https://techleads.fyi/pricing · Bulk datasets: https://techleads.fyi/bulk-purchase ### One-time / bulk dataset purchases Buy website lists for specific technologies once; CSV delivered within ~24 hours; you own the data forever (CRM-ready). | Package | Price (USD) | Notes | |---------|-------------|-------| | 1 technology | $29 | Single dataset | | 5 technologies | $49 | ~$9.80 / tech | | 10 technologies | $99 | ~$9.90 / tech | | 25 technologies | $150 | $6 / tech | | Custom (>25) | $6 / additional tech | Extends the 25-pack rate | ### Subscription plans | Plan | Monthly | Annual | What you get | |------|---------|--------|--------------| | **Founders** | $99/mo | $79/mo ($950/yr) | 10 active technologies for full lead lists; unlimited keyword searches; unlimited CSV/XLSX exports & downloadable reports; dashboard lead search; **no API access** | | **Business** | $150/mo | $120/mo ($1,440/yr) | Unlimited technologies & exports; **API access** (REST v3 + MCP with API keys); **5,000 enrichment credits/month** + buy more; alerts (email when tracked domains add/remove technologies); bulk domain lookup; export history / re-download past reports; priority support | ### Enrichment credit packs (Business / API) Credits power website technology lookups, lead enrichment, contact extraction, and API/MCP usage (1 credit ≈ 1 website lookup; email verify = 2 credits).
