GTM Flow vs Apollo: a contact database against a CRM with the prospecting inside

A note on transparency. This comparison is written by the GTM Flow team, so read it knowing one of the two products is ours. Everything we say about Apollo comes from its own website and help centre (apollo.io and knowledge.apollo.io), checked on 23 October 2026, and every source is linked at the end. Where Apollo's site does not say something, we say that instead of guessing. The short version: if you need contact data, Apollo is the better tool, and GTM Flow does not replace it.

Apollo started as a contact database and has grown into a full sales platform. Its pricing page cites 240 million contacts and 30 million companies, with filters, buying intent topics, website visitor identification and waterfall enrichment, which looks up a missing email or phone number across several data providers. Everything that touches data runs on credits: on 23 October 2026, a verified email costs 1 credit and a phone number 8 credits. On top of that sit sequences, a dialer, call recording and deal management.

GTM Flow has no contact database and no enrichment. You import the companies and contacts you already have, as a CSV, and work them from there. What it adds is the part after the list: sequences where email, LinkedIn steps, WhatsApp and calls live in the same cadence, a timeline per account with every channel on it, and AI agents that read each reply and each call and propose the next step for a human to approve. See how prospecting works and how conversations land on the record.

That is why the two are not really rivals for every buyer. If your bottleneck is finding people, Apollo solves it and GTM Flow does not. If you already know who to talk to, because you sell to a known market, work referrals or buy lists elsewhere, the question becomes which tool runs the conversations better. Some teams will use both: Apollo lists CSV export on its pricing page, and GTM Flow imports CSV.

Apollo's credits are what make its price hard to compare. On 23 October 2026 its pricing page charges 1 credit per verified email, 8 per phone number, 1 to 8 per enrichment, 1 per AI research run and, on the US dialer, 1 credit per 30 seconds. Basic's 30,000 credits a seat a year are enough for 30,000 emails or 3,750 phone numbers, and calls draw from the same pool. Unused credits do not roll over.

GTM Flow plans Solo at €39 for one person, Team at €69 and Scale at €149 per seat a month billed annually (€49, €85 and €179 billed monthly). Every plan has the CRM, sequences on all four channels and the Copilot; plans differ in Copilot requests (500, 1,000 or 3,000 a month) and team features. Telephony is billed separately, on real carrier usage. The full breakdown is on the pricing page.

The honest maths: for five seats billed annually, Apollo Basic is $245 a month and Professional $395, against a planned €345 for GTM Flow Team. But the comparison is not like for like. Apollo's price includes contact data; GTM Flow's does not. If you would have to buy data elsewhere to use GTM Flow, add that cost before deciding.

• A contact database. 240 million contacts and 30 million companies, with filters, lookalikes and buying intent. GTM Flow has no database at all: if you do not have a list, it cannot give you one.
• Enrichment. Waterfall enrichment, automated CRM enrichment and enrichment by CSV or API fill in missing emails, phone numbers and company data. GTM Flow does not enrich records.
• Signals. Intent topics on every plan (1 to 12) and website visitor identification, with a larger Inbound add-on. GTM Flow does not track external signals such as website visits.
• You can start today, for free. A Free plan with 900 credits per seat a year and a 14-day trial of paid plans. GTM Flow has no self-serve sign-up: you join the waitlist.
• A stronger dialer for volume. The Advanced Dialer add-on adds parallel and power dialing, international calls and local presence. GTM Flow calls one number at a time.
• Testing, mailboxes and integrations. A/Z testing of sequences from Professional, Google and Microsoft mailboxes, Salesforce and HubSpot integrations, an API and an MCP server. GTM Flow has no A/B testing with an automatic winner, no Microsoft 365 and no public API or MCP for customers yet.
• Scale. Apollo says more than 600,000 companies use it and shows a 4.7 out of 5 rating from 9,690 reviews on its pricing page. GTM Flow is a new product with no public reviews yet.

• WhatsApp in the sequence. WhatsApp is on the record and can be a sequence step with its own daily cap, only for people who gave you their number and permission. Our WhatsApp CRM guide covers the rules. Apollo's pricing page and sequence help pages do not mention WhatsApp.
• LinkedIn steps with limits. Apollo's LinkedIn tasks are reminders: its help centre says they must be completed by hand, with its Chrome extension. GTM Flow's LinkedIn steps have a daily cap per profile, a three-week ramp and a limit on pending invitations, and any step can still be done by hand.
• Call notes, not just a summary. After each recorded call, an agent writes the key points, each side's commitments with dates, objections in the prospect's words and questions left open. It creates up to three dated tasks, flags hot accounts and drafts the follow-up by email or WhatsApp. More in CRM with built-in calling.
• Call notes on every plan. In Apollo, Free and Basic record 150 minutes and AI insights start on Professional. In GTM Flow every recorded call gets its notes on every planned plan.
• One record for every channel. Email, LinkedIn, WhatsApp and calls on the same account timeline, so the call notes know what was said on WhatsApp the day before.
• Nothing metered. Sends, LinkedIn steps, calls and agent actions do not draw from a credit pool that expires each cycle.
• Spanish. The interface is in English and Spanish, and the team behind it sells in Spain every day. Apollo prices in US dollars, and the help centre we checked is in English.

Apollo is honest competition on the phone. Its dialer is included in Basic, Professional and Organization and uses credits; its call recording page says it records, transcribes and analyses every sales call, writes an AI summary of outcomes, next steps and objections, drafts a follow-up email and logs the activity in your CRM, including Apollo Deals. For teams that dial hundreds of numbers a day, its parallel and power dialer is a real advantage that GTM Flow does not have.

GTM Flow's difference is what happens on the record after you hang up. You call from the browser with a headset, or the CRM rings your mobile first and connects you. The recording keeps each voice on its own track, so the transcript knows who said what. The call notes then list commitments with dates, objections quoted as they were said and unanswered questions, create up to three tasks without duplicating existing ones and draft the follow-up, which waits for your click.

The notes also refuse to invent: a voicemail produces one honest sentence, not six key points, and the notes never move the deal stage on their own. You decide that, or ask the Copilot and confirm.

1. Do you know who to write to? If not, Apollo. GTM Flow cannot find contacts for you.
2. Do you need to buy now? If yes, Apollo. GTM Flow opens in waitlist order.
3. Where do your prospects answer? Email and phone are covered by both. WhatsApp points to GTM Flow.
4. How many calls a day? Hundreds, with parallel dialing, points to Apollo. Fewer calls where the notes and the follow-up matter points to GTM Flow.
5. Do you want to manage credits? Apollo's price depends on how much data and calling you use. GTM Flow's does not.

If neither fits, our B2B prospecting tools guide compares Apollo with Lusha, Kaspr, Hunter and Dropcontact for data, the multichannel outreach CRM guide covers the outreach side, and the comparisons page lists every tool we compare GTM Flow with.
