Personalize every new hire experience and save HR admin time (a lot!)
Top brands trust Pyn





Pyn gives people teams back the hours lost to manual onboarding: the repetitive emails, scheduling, and nudging managers, freeing them for higher-value strategic work. It also de-risks the process. Nothing slips through the cracks, every hire gets a consistent experience, and completion tracking proves it's working.
Because Pyn connects to Greenhouse, the journey can start the moment an offer is signed — long before day one, while the excitement is still fresh. From there every message is personalized by role, team, and location, delivered where people already work — and nothing slips.
At the same time, it scales a personal, human touch across the whole company. Every new hire feels individually looked after, strengthening engagement without adding headcount.

Start the journey before day one.
There’s a gap between offer accepted and first day on the job. For many companies, that gap is silence. No welcome message, no manager prep, no sense that anyone is ready for them. New hires sit with their excitement — and their doubts — and hear nothing.
Pyn closes that gap. The moment Greenhouse marks a candidate as hired, Pyn starts their pre-boarding journey. No manual handoff. No waiting for the HRIS to catch up.
Why connect Pyn and Greenhouse?
Act at the moment of hire. When Greenhouse updates a candidate’s status to hired, Pyn picks it up and kicks off pre-boarding automatically. A welcome message, a manager nudge, an IT checklist — all triggered before anyone has to think about it.
Make new hires feel ready, not forgotten. The period between offer acceptance and day one shapes how someone feels about joining. Pyn uses the data from Greenhouse to send personalized messages that feel like they came from a person — by name, for their role, from their manager.
Give managers time to prepare. Pyn can send prep reminders and conversation starters to hiring managers as soon as the hire is confirmed in Greenhouse. By the time the new hire walks in, their manager is ready.
Build the full picture with your HRIS. Greenhouse gives Pyn the early signal: who’s joining, when, and in what role. Once your HRIS is updated with the full employee record, Pyn picks up from there and carries the journey through onboarding and beyond. Together they cover the entire employee lifecycle from offer to offboarding.

FAQs
When does Pyn start the pre-onboarding journey?
When a candidate is marked as hired in Greenhouse. Pyn picks up the trigger automatically and no manual handoff is needed.
Do I still need an HRIS integration?
For pre-onboarding, Greenhouse is enough. For the full employee lifecycle — promotions, anniversaries, internal moves, offboarding — you’ll want an HRIS connected too. Pyn works with both, and the two integrations complement each other well.
Can I personalize pre-onboarding messages by role or department?
Yes. Pyn uses the role, department, and hiring manager data from Greenhouse to tailor every message from day zero.
Where do messages get delivered?
Slack, Microsoft Teams, or email — wherever your people actually work.
Is my data secure?
