Customer onboarding software · for HubSpot CS teams

Churn doesn't start at renewal. It starts at kickoff.

Congratulations. They bought your software. Now they're emailing you to ask what happens next.

Herofy drafts the onboarding plan from what sales promised and what the customer wants, then flags a stalled account on day three instead of week three.

They need a hero. You need a sidekick.

For B2B SaaS teams on HubSpot with high-touch accounts, whether onboarding is your whole job or your fifth one. Limited spots. We build it with you.

The 90-second tour

They bought your software… now what?

Here's what happens next, with way less chasing.

Works with your stack

Nothing to migrate. It reads what you already use.

Where it starts
HubSpot

Deals, notes, and logged calls, so every plan starts from what sales promised. A deal hitting closed-won kicks off the handoff on its own.

Gmail + Google Calendar

Customer threads, and the meetings tied to them.

Outlook + Microsoft 365 Calendar

The same, for Microsoft shops.

Slack

Customer conversations in the channels you connect.

Microsoft Teams

Your chats with customers, and the updates your team trades about them.

Grain

Call transcripts, turned into account updates you confirm.

Notion

Handoff docs, onboarding trackers, and account notes.

Replies leave from your inbox

Send from Gmail or Outlook without switching tabs. Sidekick drafts; only you can click send.

What you can do now

Your new superpowers.

Connect HubSpot and the busywork that used to eat your week becomes three things you approve.

01 / DAY ONE

Your entire book, mapped in minutes.

Sales hands you a closed deal and a blank page. Connect HubSpot and Gmail, and Sidekick fills the page: it reads each account's deal notes and email threads, finds what was committed to, and drafts an onboarding plan. Every plan shows its evidence and its confidence. When it isn't sure, it says so.

02 / EVERY MORNING

The ten-minute loop.

Open Herofy and see who's stalled, on which goal, and why, with the actual quotes. Sidekick has already drafted the nudge that gets them moving. Edit it and send it, or skip it. You're the one who saves the day.

Evidence: we'll pull the export this week, Dana, last Tuesday. No file received; page unopened.
Hi Dana, no rush, but the data export is the one thing between us and your go-live date. Here's the page again; it takes about five minutes. Happy to hop on a call if the format's fuzzy.
03 / WHEN THINGS SLIP

The plan fixes its own dates.

A milestone slips or a blocker clears. Sidekick re-sequences everything downstream and shows you what moved and why. You approve the new dates, once, on purpose, instead of watching the launch drift a month while nobody says anything. Nobody rebuilds the plan in a spreadsheet at 6pm on a Friday.

The guardrail

Sidekick prepares. You decide.

Sidekick drafts and keeps watch, but it has no way to contact your customers. And everything it does leaves an evidence trail you can follow back to the source.

It can't reach your customers.

Sidekick works your side of the desk. It writes the plan and the nudges, but you're the only one who can hit send.

You can read its rules.

Everything Sidekick does follows a plain-English handbook you can open and edit yourself. No black box, no settings maze.

Everything traces to evidence.

Every plan and every flag links back to where it came from, whether that's an email thread, a deal note, or a call. Follow any claim to its source.

Another tool?

One more login, yes. But there's nothing to migrate. Herofy reads what's already in HubSpot, your inbox and calendar, Slack or Teams, Notion, and Grain, so it earns its keep the first morning. It's the tab that closes the other four.

We already have an onboarding checklist.

So does everyone who churned a customer at 100% completion. A checklist tracks your work. Herofy tracks what the customer said they wanted, pulled from the deal notes and the call transcripts, and runs the plan against that. Same tasks, different scoreboard.

AI will embarrass me in front of a customer?

Nothing leaves without you. Sidekick drafts; you approve every word before it goes anywhere.

Couldn't I rig this up with a chatbot?

A chatbot waits for someone to type. Sidekick reads the deal notes before you do, watches every account overnight, and can't message your customers even if you asked it to. Different job.
