Crunchbase Mobile Proxies for Company Research

Crunchbase is a reference database of private companies, funding rounds, acquisitions and the people behind them. Investors, sales teams and analysts use it daily. Its business model is also explicit: a free tier with limited views, paid plans with more fields and exports, and an official API for programmatic access. That shapes what a proxy is good for here. This page explains where the data boundary sits, which jobs a dedicated WeProx US mobile line genuinely helps with, and why the API should be your first stop for anything that looks like bulk collection.

The API is the front door

Crunchbase offers an official API with organization, person, funding round and acquisition entities, plus search and autocomplete. Access and field coverage depend on your plan, and the terms of use restrict scraping the website as a substitute. For any pipeline that needs many records, structured fields, change tracking or joins to your CRM, the API is faster to build, more stable, and the only approach that fits the rules. It also returns clean identifiers, the permalink and UUID for each entity, which save you from fuzzy company-name matching later.

Rate limits on the API are part of your plan and are enforced by key, not by IP, so a proxy does nothing for API throughput. If you need more, that is a plan conversation, not a network one.

What a line is actually for

The website view matters for a different set of questions. Founders and marketing teams check how their own company profile looks to a logged-out US visitor: which funding rounds show, whether the description and logo are current, and what the free tier reveals. Sales teams on corporate VPNs or overseas contractors sometimes see extra verification prompts because their shared exit IP carries a lot of traffic, and a dedicated US line gives them a stable, ordinary consumer address for normal manual use of their own paid seats. Analysts spot-check a small number of profiles against API output to catch mapping mistakes.

None of these involve pulling large numbers of pages. They are the kind of work a person does in a browser, and the line simply gives that person a clean, stable US address to do it from.

• Checking your own company profile as a logged-out US visitor.
• Giving a sales seat a stable US connection for manual use.
• Spot-checking API results against the public profile page.

Session habits that keep accounts healthy

Crunchbase accounts are licensed per seat, and account security looks for unusual patterns such as one login appearing from many places at once. Keep one seat on one line, keep the line sticky through the whole working session, and do not rotate while signed in. A WeProx line is a single US carrier device dedicated to you, so the address does not change unless you call the rotation link. Its IP sits in the carrier's CGNAT pool with ordinary phone users, which is why sign-in checks treat it as normal consumer traffic rather than as a hosting range.

Do not share seat credentials across people to stretch a plan; that is a terms issue, not a technical one, and routing it through a proxy does not change it.

Metro choice

Crunchbase content does not change by US region, so any WeProx metro with stock works, whether New York, Chicago, Houston or Phoenix. Choose a line near your team if you want the lowest latency for manual browsing. If your team is outside the US, the line mostly serves to present a steady US consumer connection for your own licensed use.

Troubleshooting

Fields that appear blurred or locked are plan limits, not a block; no network change affects them. Repeated sign-in verification means the session's IP moved or another person is using the same seat. Slow page loads on a busy evening are carrier conditions, and a 5G line helps where available. If the line fails an IP-echo test, check the port and credentials, then contact WeProx support with the line ID. For API errors, read the response body; they are about keys, quotas or query shape, never about the proxy.

Setting up a Crunchbase proxy on WeProx

1. Confirm whether the official API on your plan covers the job; if it does, use it.
2. For website checks, order a WeProx line near your team.
3. Create a browser profile with the line's host, port and credentials.
4. Sign in with your own seat and keep the line sticky all session.
5. Use a clean profile with no cookies for logged-out profile checks.
6. Spot-check a few profiles against API output each week.
