GTM Flow vs Attio: a flexible CRM 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 Attio comes from its own website and help centre (attio.com and docs.attio.com), checked on 23 October 2026, except its funding, which comes from press coverage of the round. Every source is linked at the end. Where Attio's site does not say something, we say that instead of guessing.

Attio is built for teams that want the CRM to fit how they work rather than the other way round. You can add custom objects beyond people, companies and deals, enrich records automatically, build workflows, and reach your data through its API or its hosted MCP server, which lets AI tools search and update records. That is a real advantage if your sales motion is unusual, such as investor relations, partnerships or a marketplace with two sides.

On 23 October 2026, Attio's sequences help page describes sequences made of email steps and waits, sent through your synced Gmail or Microsoft account, with up to 1,000 recipients enrolled at a time. Its email outbox page caps each synced mailbox at 12 emails an hour and 200 a day, sequences included. Attio's own help pages do not describe LinkedIn, WhatsApp or call steps inside a sequence; those channels come from apps in its App Store.

GTM Flow treats those channels as part of the sequence. One cadence can send email from your own mailboxes, add LinkedIn steps with per-profile limits or as manual tasks, send a WhatsApp message to people who gave you their number and permission, and schedule a call, all on the same record. When someone replies on any channel, the cadence stops and the AI agents create the task. See how prospecting works and how conversations land on the record.

Attio's workflows and AI features draw from a monthly pool of workspace credits, and each seat has its own credits for Ask Attio. If your workflows run out of credits, Attio sells extra packs. Phone calls need a separate telephony app such as Aircall or RingCentral, and two-way WhatsApp needs the TimelinesAI app, each with its own subscription.

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. Sends, LinkedIn steps, calls and agent actions are not counted. The full breakdown is on the pricing page.

The honest maths: if you only need a flexible CRM, Attio Free and Plus are cheaper than anything GTM Flow plans. If you need sequences, the fair comparison is Attio Pro at €74 a seat against GTM Flow Team at a planned €69: for five seats, €370 against €345 a month billed annually. The gap is small; what changes is that GTM Flow's sequence also covers LinkedIn, WhatsApp and calls.

• You can start today, for free. The Free plan covers up to 3 seats, and Attio offers a 14-day trial of Pro. GTM Flow has no self-serve sign-up: you join the waitlist.
• A flexible data model. Custom objects (up to 12 on Pro, unlimited on Enterprise), custom attributes, private lists and workflows. GTM Flow's model is fixed: companies, contacts, opportunities, lists and tasks.
• API, MCP and ecosystem. API access on every plan, a hosted MCP server for AI tools and an App Store with apps such as Aircall, RingCentral, Ringover and JustCall. GTM Flow has no public API or MCP server for customers yet.
• Microsoft mailboxes. Attio sends through synced Gmail or Microsoft 365 accounts. GTM Flow does not support Microsoft 365.
• Video meeting recording. On Pro, a recorder joins Zoom, Google Meet and Microsoft Teams calls and returns transcripts, AI summaries and insights. GTM Flow records the calls you make from the browser, not video meetings.
• Funding and scale. Attio raised a $52 million Series B in August 2025, backed by GV, Redpoint Ventures and Balderton Capital, for about $116 million in total; press coverage of the round put its customers at more than 5,000 companies. GTM Flow is a new product with no public reviews yet.

• Four channels in one sequence. Email, LinkedIn steps, WhatsApp and calls in the same cadence, with a daily cap per LinkedIn profile, a three-week ramp and a limit on pending invitations, and any step can be done by hand. Attio's sequences are email steps.
• WhatsApp without another subscription. 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. In Attio, two-way WhatsApp comes from the TimelinesAI app.
• Phone calls built in. Calls from the browser with recording, transcription and automatic notes, on every plan. In Attio, phone calls need a telephony app.
• Sequences on every plan. In Attio they start on Pro at €74 a seat billed annually. In GTM Flow they are in Solo too.
• Cold email from your own mailboxes. Mailbox rotation, per-mailbox daily caps and address checks at enrolment. The B2B cold email guide explains why that matters.
• Nothing to design and nothing metered. The model is ready on day one, and sends, LinkedIn steps, calls and agent actions are not counted against credits.
• Spanish. The interface is in English and Spanish, and the team behind it sells in Spain every day.
