Source Is AO a drop-in replacement for Attio?
Not for every team. If you rely on custom objects and your own workflows, Attio is built for that. AO is for small SaaS teams that want the CRM to fill itself in from billing, product usage, bookings and email, and to draft the reply to every inbound lead.
Can I try AO without a card?
Yes. Every workspace starts with 14 days of Starter, no card. After that it moves to the Free plan unless you choose a paid one.
Does AO connect to Stripe and PostHog?
Yes, from Starter. Both are read-only: AO never changes your billing or your app.
