Been testing both for about 2 weeks now and cant decide. My team needs solid cell numbers for our outbound, were doing about 300-400 dials a day accross 3 SDRs.

Swordfish seems to have decent coverage but im seeing some stale numbers. Like I called 20 people yesterday and 4 were disconnected. Thats 20% waste right there. Prospeo's numbers seem fresher but I havent done enough volume to really know yet.

Anyone here run both phone number finder tools side by side? Main things I care about:

• Actual connect rates on mobile numbers (not just "we found a number")
• Pricing at scale (we'll probably need 5-10k numbers monthly)
• How often they update thier database
• Coverage for tech companies specifically

Also curious if either has good API speeds. We're using Outreach and want to pull numbers on demand rather than batch enriching everthing.

Price-wise Prospeo seems way better value but wondering if that means the data quality suffers. Swordfish is like 2-3x more expensive from what I can tell. We also looked at ContactOut briefly but thier mobile number coverage was pretty thin for our ICP.
