Apollo runs the outreach. Proxi decides who is worth reaching this week, and hands your rep the public record that explains the timing.
TLDRApollo.io is a contact database plus outreach platform: sequences, dialer, and emails, priced per seat and credits. Proxi is the industrial database tracker: it watches 11M+ physical-economy businesses across 10,000+ public sources and tells your reps who to call and why now, with the permit, locate ticket, or award as evidence. Apollo runs the outreach; Proxi decides who deserves it this week.
Apollo.io pairs a large contact database with an engagement platform: sequences, email sending, a dialer, and the reporting around them. For a software or services team running high volume outbound into the office economy, that is an efficient stack, and it is priced the way that motion works, per seat with credit packs for data. If your constraint is sending more, faster, with fewer tools in the way, Apollo is aimed squarely at you.
Proxi is the industrial database tracker. It reads more than 10,000 public record sources continuously (state business filings, 811 locate tickets, construction and environmental permits, licenses, procurement awards, court records, job postings, and the open web), resolves every record to one of over 11 million businesses in the physical economy, and every morning ranks the businesses in your territory by what their records just did. Each name arrives with the record that put it there and a phone number.
Where the difference shows up. Outbound tooling multiplies whatever list you feed it. If the list is a filter on static firmographics (an industry code, a headcount band, a state), a faster sequencer just sends more mail to companies with no reason to answer. The physical-economy businesses that buy equipment tend to be thin in contact databases and rich in public-record activity: they file, permit, locate, bid, and hire in the open. Proxi turns that activity into an ordered list of roughly fifteen calls with a reason attached to each one, which is a different sort of input than ten thousand rows.
| Proxi | Apollo.io | |
|---|---|---|
| What the data is | Live public records resolved to one business: filings, permits, 811 locates, licenses, awards, court records, hiring | A contact and company database plus an engagement platform (sequences, email, dialer) |
| Question it answers | Who to call this week, and why now | How do I reach a lot of the right people efficiently |
| Freshness | Every source polled on its own publishing cadence, from minutes to daily; the call sheet is rebuilt each morning | Continuously maintained contact records, plus live engagement activity from your own sending |
| Unit of coverage | Every business inside a territory (11M+ businesses in the physical economy) | Contacts and accounts, weighted toward the office economy |
| Workflow output | A ranked call sheet with the record behind each name and a phone number, pushed into your CRM | Sequences, sending, dialing, and reply tracking |
| What it is not | Not an engagement tool: Proxi does not send, sequence, or dial | Not a public-records tracker: coverage is contact and company data, not filings and permits |
| Pricing model | Per territory, not per seat | Per seat and credit packs |
Yes, and that is a common setup. Proxi produces the ranked list and the reason to call. Apollo runs the sequence, the sending, and the dialing. Nothing in Proxi competes with the engagement layer, so the two stack cleanly.
No. Proxi stops at the decision: who to call, why now, and the public record that proves it. Sending, dialing, and follow up stay in the tools your team already lives in.
No. The ranked list and its evidence are pushed into the CRM you already use. Proxi is an input to your pipeline, not a second place to keep deals.
Because the work is territory shaped. Watching every business in a region across every public source costs the same whether two reps or ten read the result, so charging by seat would only tax you for putting more people on the same call sheet.
