From signup to support to growth - Flow turns your app into a real business.
You vibe coded the product. Flow handles the business systems people forget to finish.
The API sends context. Flow turns it into onboarding, support, growth, and follow-up work.
This is the useful part: one chat can segment Product Hunt signups, answer blocked-user threads, launch a re-engagement sequence, and generate a landing page for your next feature release without dragging you into a mess of tools.
Maya from Product Hunt just started a Pro plan.
A billing question opened for workspace 22 and needs attention.
An annual 12-seat plan came through from the Spring launch campaign.
The product is live, signups arrive, and then the real work appears all at once: onboarding, support, follow-ups, segmentation, launch campaigns, CRM cleanup, and internal ops. Most builders do not need more dashboards. They need one system that can actually run the work.
Send the signals your app already has. Flow uses them to run the onboarding, support, and follow-up work most teams never finish.
Create an API key, use stable identifiers, and decide which lifecycle moments actually matter to the business.
Push signup, activation, purchase, support, source, and plan state into DealsFlow so the workspace has real context.
Run onboarding, support triage, lifecycle follow-ups, campaigns, landing pages, and internal ops from one chat.
These are the systems solo builders and app teams always mean to build later, then never want to maintain.
Trigger welcome emails, activation nudges, and next-step sequences as soon as a new user signs up.
Use email and inbox workflows with customer memory attached so support context stops disappearing.
Find people who signed up but never activated, then draft or send re-engagement from chat.
Split Product Hunt traffic, ad users, paid accounts, churn risk, or activation level without building a separate CRM machine.
Create launch emails, feature pages, images, and follow-up sequences from the same workspace that knows your users.
Use one chat to understand signup flow, support load, campaigns, activity, and where users are getting stuck.

}Stable external_user_id values plus clean metadata are what make segmentation, memory, support, and follow-up actually useful.
The Developer API is the bridge between your product and the rest of the business. Feed Flow user lifecycle context, support signals, plans, sources, and timestamps, then use that data across chat, automations, email, inbox, campaigns, landing pages, and proactive follow-up.
external_user_id values so Flow always maps actions to the right customer.You already used AI to ship faster. Keep going. Do not spend the next month rebuilding support, CRM memory, onboarding, follow-up logic, and launch ops from scratch inside your own stack.
Ask in plain English. Flow figures out the follow-up, support, launch, and growth work from there.
Send your signup and product signals to Flow, then let it run onboarding, support, follow-ups, and launch work without you wiring a pile of internal tools.
