Not a paid rank
Live CRM quiz scores for a typical buyer leaving Salesforce. Scores are 0–100 against a perfect match and never read affiliate status. See the category →
01Problem
The stack you already pay for is the one your team stopped updating.
Afterstack is not a passive directory. It is replace, then match, then migrate — with a partner only when the cutover is too complex.

02Match
Any major SaaS category with an AI-native crop.
Incumbents people leave, and the software replacing them. CRM, Support, Sales engagement, Recruiting, Marketing, and Knowledge have scored quizzes today. Paid profiles never move a rank.
AI-native substitutes we actually list.
Support agents, recruiting, sales engagement, marketing, knowledge, and CRM. The crop is the catalog, scored from a quiz — not a paid slot.
AI customer service agent meant to resolve, not just deflect to a queue.

Paid placement never moves a list.
The scored quizzes publish fit from 0 to 100 against a perfect match. Affiliates and claimed profiles are disclosure, not rank. Specialists never enter a software shortlist.
100 is a perfect match.
The published score is the share of the most those answers can award: attributes at the top of the scale, every matching feature, and the replacement bonus when you are leaving a tool. Hard filters still drop what cannot work. Affiliates never move the number. Specialists stay outside the software rank.

03Migrate
Map the migration. Escalate only if you must.
When the substitute is chosen, the Migration Agent writes a plan for that pair and coaches the cutover step by step.
01
Match an AI-native substitute
Search a live category or open a scored quiz. Fit is 0–100 against a perfect match, hard-filters mismatches, and never uses affiliate payout or placement.
02
Open the Migration Agent
An LLM agent drafts a detailed plan from your pair and context, then walks it step by step. General guidance, not vendor docs.
03
Partner if it is too complex
High-complexity switches surface migration specialists. Services are the escalation path — they are never a paid software rank.
04Partners
Migration specialists, not a consulting brochure.
Partners are the escalation when a Migration Agent plan is high-complexity. They never enter a software rank. Afterstack is not a consultancy.

Guides
Buyer guides
Afterstack-owned answers to leave questions. Affiliates never affect ranks.
CRM
Replace Salesforce with an AI-native CRM
Salesforce is the CRM most teams already pay for. The leave job is a system of record built around how you actually sell — not another copilot on last decade’s objects. Afterstack starts from the incumbent, then matches a substitute. Affiliates never change the order.
Customer support
Leave Zendesk for AI agents — only if resolution is the job
Zendesk is the ticket queue most support orgs already pay for. The leave job is often resolution — not another macro pack on the same desk. Afterstack lists AI agents in the same category because buyers shop them that way, then distinguishes layer from desk in the briefing.
Sales engagement
Outreach vs an AI SDR: sequencer seats or digital workers
Outreach is how many SDR floors already run: sequences, dialer, and enablement around a human pod. An AI SDR is a different buy. Afterstack keeps those jobs in one category, then splits them so you do not purchase a prettier cadence UI when you meant to replace the floor.
Recruiting
Greenhouse alternatives when recruiting needs an AI-era ATS
Greenhouse is the structured-hiring ATS many TA teams still standardize on. The leave job is usually a modern ATS with analytics — not a matching marketplace, and not a sourcing layer pretending to be reqs. Afterstack ranks Greenhouse leavers as ATS products first.
Marketing
Marketo alternatives after the AI layer — content, site, or the MAP
Adobe Marketo Engage is the B2B marketing automation incumbent. Buyers leaving it often wanted on-brand generation or account-aware pages, then got another program in the database they already resent. Afterstack splits those jobs so a writer is not sold as Journey Builder.
Knowledge
Confluence vs AI enterprise search — pages versus answers
Confluence is the wiki incumbent every team meant to keep current. “Replace Confluence” often means “stop searching Confluence.” Afterstack lists AI search in the same category, then says Glean is not always a 1:1 wiki replacement.
Head-to-heads
Selective AI-native versus incumbent pairs. Editorial positioning, pricing bands, and a Migration Agent path. Affiliates never rank either side.
All compares- Attio vs SalesforceSalesforce is the CRM most teams already pay for. Attio is the AI-native data layer Afterstack lists when the objects, relationships, and activity should flex around how you actually sell — not last decade’s standard objects.
- Attio vs HubSpotHubSpot still wins if marketing automation and a free CRM are the job. Attio wins if the objects, relationships, and AI should flex around how your team actually sells — without growing into a second marketing cloud.
- Clarify vs PipedrivePipedrive remains the clearest visual pipeline in the category. Clarify’s bet is that the pipeline should fill itself — notes, emails, and next steps captured without a data-entry culture.
- Sierra vs ZendeskZendesk is the ticket queue most support orgs already pay for. Sierra is an AI customer-experience agent Afterstack lists when the leave job is resolution, not another macro pack on the same desk.
- Ada vs ZendeskAda is an AI customer-service platform Afterstack lists when deflection is not enough — the agent should resolve. Zendesk remains the desk most teams pair with, or try to leave.
- Pylon vs IntercomIntercom is messenger-first support — Fin is listed separately because teams shop the agent. Pylon is a B2B support hub for Slack, Teams, and account teams tired of forcing every conversation into a consumer-style messenger.
- 11x vs OutreachOutreach is the enterprise engagement incumbent — sequences, calls, and a lot of admin. 11x is listed as an Outreach-class substitute when the leave job is an AI SDR that works the list, not a prettier cadence UI.
- Clay vs ApolloApollo is data plus engagement in one seat — the volume outbound incumbent for SMBs. Clay is the AI-native GTM data workbench Afterstack lists when enrichment, research, and the first touch should be programmable, not a credit waterfall inside a sequencer.
Trust
Affiliates are a disclosure. Never a dimension.
Read the model, the FTC note, and how vendors get listed. Nothing here is a paid software rank.
