What it costs to leave, and what actually replaces what

This is the whole test. A vendor that has built the export will send it in a day. A vendor that has not will offer a call about it.

Contacts are the easy part and usually the only part. The history is what makes the next platform useful on day one.

A window described in a help centre can be changed without telling you. A window in the agreement cannot.

Derived data is frequently excluded from export clauses, and it is often the part you paid the most for.

An export that exists but is billed as a project is a switching cost with a different name.

Reputation and numbers are carried by the platform. This is why a clean data migration still costs a quarter of performance, and why 189 of 249 vendors would rather discuss it later.

What tools can replace Apollo.io for lead generation?

The first useful thing the index can tell you is that replacing Apollo.io is usually 3 purchases rather than one. It is indexed in 3 categories at once, Data & Enrichment, Sales Engagement & Outreach, Dialers & Voice, which is why buyers who swap it for a single tool tend to discover a gap a quarter later. The second is what you would be giving up. Apollo.io holds a top grade on 4 axes: Commercial Transparency, Data Licensing and Provenance, Data Privacy Posture, Outreach Compliance Posture. That is a genuinely strong record on the questions that decide a data purchase, and most of the tools marketed as alternatives do not match it. Where it is weaker is Deliverability and Sending Discipline, and it sits at a C on Exit and Data Portability. If switching cost is what is driving the search, the vendors that document the exit better than Apollo.io does are, in data and enrichment, 19 of 94; in sales engagement, 50 of 200; and in dialers and voice, 15 of 54. They are named on this page. That list is arithmetic, not a recommendation: it is every indexed vendor sharing a lane with Apollo.io that carries a strictly better grade on that one axis.

What should a sales team check before switching sales engagement platforms?

Check the exit before you check the features, because the exit is where this category is weakest and it is the part nobody demonstrates. 50 of the 201 platforms in the sales engagement lane document what a customer gets back on the way out, 25 percent, with 5 at the top of the scale and 23 carrying a D. Four things decide the real cost of the move. What comes out, meaning whether sequences, activity history, engagement events and call recordings are exportable or only contacts. In what format, because a PDF of your activity history is not a migration. On what timetable, since export windows that close days after termination are common and are usually discovered late. And what stays behind, because sending reputation is carried by the platform and does not travel with you, which is why teams that switch cleanly on paper still see deliverability fall for a quarter. Ask for the export schema and a sample file during evaluation rather than during termination. A vendor that has built the export will send it.

Which go to market vendors document what you get back when you leave?

60 of 249, 24 percent, and only 7 at the top of the scale: Bigin by Zoho CRM, Cirrus Insight, Evergrowth, Koncert, Rolodex, Snov.io, Tuvis. 158 vendors sit at a C and 31 at a D, which together is 189 of the index treating offboarding as something to discuss after you have signed. This is the least documented commercial axis in the whole index and the gap is not close. CRM & Systems of Record is the best category at 34 percent and Marketing Automation & ABM the worst at 7 percent. The asymmetry is deliberate on the vendor's part rather than accidental: an export path that is easy to find is a switching cost the vendor has chosen to lower, and most have chosen not to.

How does the GTM Tech Index grade exit and data portability?

On what a buyer can establish about offboarding before signing, from public artifacts. Offboarding is documented before signature: full export paths for customer created and engagement data, post termination rights to delivered data stated in public terms, deletion commitments with timelines, and renewal notice terms a buyer can plan around. A C means: Export exists as a feature claim while the terms that govern exit, data rights after termination, deletion, and auto renewal mechanics, are not published anywhere a buyer can read. The axis was added to the index spine in August 2026 because no comparable index grades it, and because the cost of leaving is the part of a software decision that is hardest to reverse and easiest to ignore during a demo. A grade records what the vendor has published rather than what it would do on request, so a low grade means the answer is not public rather than that the export does not exist. Every grade carries a source basis and a verification date on the vendor profile, and grades are never aggregated into a composite score.
