Our pick

AI Ark wins on credit cost per mobile number. A found mobile number costs 5 credits on AI Ark against 10 credits on FullEnrich, so the same count of numbers costs half the credits. Free is $0 a month for 100 credits. Usage-Based is $49 a month billed monthly for 5,000 credits, or $470 a year billed yearly for 60,000 credits. A found email costs 1 credit: half a credit for the person record and half a credit for the email itself. Apollo wins when a database and a sequencer, the tool that sends your email steps over days, under one login beats running two tools. Basic is $49 per seat a month billed yearly, or $65 per seat a month billed monthly. BetterContact and Prospeo both work as one step next to a waterfall. Neither one replaces the whole waterfall: BetterContact fits as a last hop after cheaper finders miss, and Prospeo fits as an early or middle step for lists pulled from LinkedIn Sales Navigator. FullEnrich stays the pick when the managed waterfall, a search across several providers in order until one finds a match, is what you need run for you. Pro is $55 a month billed monthly for 1,000 credits, with a mobile number at 10 credits, a work email at 1 credit and a personal email at 3 credits.

MethodHow we scored these tools▾

Prices come from each vendor’s published plans. AI Ark and Apollo show monthly and yearly options. FullEnrich’s credit costs come from its published plan. BetterContact and Prospeo are described by what teams use them for, without prices. The math covers 200 mobile numbers split between FullEnrich and AI Ark.

Who it's for

buy if

  • You pay FullEnrich for mobile numbers and want a lower credit cost per phone number found.
  • You want a list source, a database you search yourself, instead of paying a waterfall for every lookup.
  • You run contact search and email sending from one login and want fewer tools to manage.

skip if

  • Skip a move if you need one call that searches more than 20 providers in order and you do not want to run that search yourself. Stay on FullEnrich for that.
  • Skip a move if you already hold a seat on Apollo, one user login, and you send sequences from it. Check the math below before you add a second data tool.

The short answer

Pick AI Ark if you want a database of contacts with a lower credit cost per mobile number, a cell phone number. AI Ark charges 5 credits for a found mobile number, and $49 a month billed monthly buys 5,000 credits.

Pick Apollo if you want a database and a sequencer, the tool that sends your email steps over days, under one login. Basic is $49 per seat a month billed yearly, or $65 per seat a month billed monthly.

Pick BetterContact or Prospeo if FullEnrich still fits your flow but you want a second finder to run next to it, as an early step or a last hop.

Stay on FullEnrich if you want a managed waterfall run for you without setting it up yourself. Pro is $55 a month billed monthly for 1,000 credits.

What 200 mobile numbers cost on FullEnrich and AI Ark

The math: send 200 mobile numbers, cell phone numbers, through each tool’s credit cost.

FullEnrich: 200 × 10 = 2,000 credits. Pro gives 1,000 credits for $55 a month billed monthly, so 200 mobile numbers need more than one month of credits.

AI Ark: 200 × 5 = 1,000 credits. That sits inside the 5,000 credits on the $49 a month billed monthly Usage-Based plan, with room left over the same month.

How a credit buys an email or a mobile number

A credit is a unit you spend per contact found. On AI Ark, a found email costs 1 credit, half a credit for the person plus half a credit for the email, and a found mobile number costs 5 credits. On FullEnrich, a mobile number costs 10 credits, a work email 1 credit and a personal email 3 credits.

A waterfall is a search across several providers in order until one finds a match. FullEnrich runs that search for you and charges credits when it finds a result. AI Ark is a database you search yourself, so it works as a first pass, a list source to fill from before you pay for a waterfall on the contacts still missing a number.

A seat, one user login, on Apollo bundles contact search with a sequencer, the tool that sends your email steps over days, so sending does not need a separate tool.

When staying on FullEnrich still makes sense

Stay on FullEnrich if the waterfall is the point: mobile numbers that are hard to find when one database keeps missing them, and paying more per credit beats setting up a login at more than 20 providers yourself.

FullEnrich also fits as a last step after cheaper finders, including AI Ark, BetterContact or Prospeo, have already run and left a short list of contacts still missing a number. Pro is $55 a month billed monthly for 1,000 credits, with a mobile number at 10 credits, a work email at 1 credit and a personal email at 3 credits.

What to do next

Count the mobile numbers, cell phone numbers, your list needs each month, then weigh that count against the credit cost on each tool. If FullEnrich’s waterfall still earns its higher credit cost for the hard to find numbers, keep it for those. If you want a lower credit cost per mobile number and a database you search yourself, start on AI Ark’s free plan with 100 credits a month. Try AI Ark
