See which companies visit, and what they do.
Most visitors leave without filling in a form. Porchlit names the company behind the visit, shows what they read and how long they stayed, and enriches each one with what the company does, its size and where it is based. We built it ourselves, with our own tracking pixel and our own IP-to-company engine.
Build vs buy
Why we built it instead of paying $79 a month
Website visitor identification tools are priced per month, per identified company and often per site. The entry plans cap you at around 50 companies a month, and the serious ones run to thousands of dollars a year. We wanted it on our own site and on Mero's, with the data in our own database and no cap on how many companies we look at.
| Tool | Plan | Per month | Per year |
|---|---|---|---|
| RB2BPerson-level visitor ID, US | Starter, 300 resolutions | $79 | $948 |
| Leadfeeder (Dealfront)Company visitor ID | Discover, 50 companies, monthly | €113 | €1,356 |
| SnitcherCompany visitor ID | Entry, 50 companies | $49 | $588 |
| AlbacrossCompany visitor ID | Professional, 500 companies | €149 | €1,788 |
| WarmlyVisitor ID + intent | Web de-anonymization | ~$833 | $10,000 |
| Porchlitour own, on our own server | Unlimited companies, every site we run | $0 | $0 |
Vendor list prices checked on 13 November 2026 from each vendor's pricing page (Leadfeeder is €79 a month if paid yearly). Porchlit has no licence fee. It runs on a server we already use for other tools, and company enrichment through Clay costs about half a credit per new company.
No per-company cap
Entry plans stop at about 50 companies a month. Porchlit shows every company it can identify, on every site we install it on.
Honest about what it knows
Home Wi-Fi, mobile networks and VPNs stay anonymous with a reason, instead of being dressed up as a company. Every match shows its evidence and a confidence score.
Enrichment we control
Each company is profiled from its own website, then enriched with headcount, revenue, location and LinkedIn, automatically, only once it is identified.
Plugs into everything
A REST API, CSV and JSON exports, and an MCP server, so Claude can answer "which companies looked at pricing this week?"
What we built
A full visitor intelligence product
Porchlit is a complete product: a landing page with a waitlist, email-code sign-in, multi-workspace accounts, a dashboard, an API, an MCP server and legal pages. It runs on every page of ivconsulting.in.
Companies, ranked by intent
Every identified company with its logo, domain and a 0 to 100 intent score. Segments like High intent, Visited pricing and Returning are built in, and you can add your own.
Who they are and what they do
Open a company to see how it was identified and how sure we are, what the company does in its own words, and enrichment from Clay: headcount, revenue range, location and LinkedIn page.
An honest match rate
The overview counts only human sessions and says where every unmatched one went: home internet, mobile, VPN or a cloud server. Bots and crawlers are filtered out before they reach your list.
A product, ready to sell
A landing page, waitlist, approval flow and invite emails. Porchlit is built as a multi-tenant product we can open to customers, not an internal script.
Dashboard screenshots use a demo site with sample traffic from public company networks. Enrichment shown is real Clay output for that company.
How it works
From an IP address to a company profile
No identity vendor sits in the middle. Porchlit uses free public records and what it learns from your own visitors, then enriches only the companies it is confident about.
- PixelOne script tag records pages, time on page and form fills, first party, respecting Global Privacy Control.
- NetworkThe visit's IP is matched to its network owner using open IP-to-network data and public registry records.
- FilterHome, mobile, VPN, cloud and crawler traffic is set aside with a reason, never guessed.
- CompanyBusiness networks are matched to a company, with evidence and a confidence score.
- ProfileThe company's own website gives its description, keywords and the technology it runs on.
- EnrichClay adds headcount, revenue range, location and LinkedIn, automatically and only once.
- ActScores, segments, exports, the API and the MCP server put the list where your team works.
Engineering
How we built it
Built with Claude Code as a zero-dependency Node service with an embedded database. Then we kept making it more accurate, one audited false positive at a time.
Audited every day
A daily routine checks every newly identified company. Each false positive became a rule, and a 38-network control test runs before every release.
Companies, not people
People are only named when they share their details in a form. IP addresses are cleared after 90 days and any workspace can delete its data itself.
API, exports and MCP
Scoped API keys, a documented REST API, CSV and JSON exports, and an OAuth-protected MCP server with 8 tools for Claude.
Multi-tenant from day one
Workspaces, invites, an admin view, audit logs and a per-workspace enrichment switch, so it can be offered to customers.
Built for you
Need data, enrichment or a custom SaaS tool? This is the proof.
We are often asked for enrichment pipelines, lead data systems and internal tools that replace a monthly subscription. Porchlit is all three.
