The problem

Two systems. One day. Endless reconciling.

Your CRM tracks what needs to happen. Your calendar tracks when it happens. Without a bridge, you become the bridge, and either you, the work, or your time suffers for it.

// 01

HubSpot holds the work

Calls, follow-ups, deal stages, queued tasks — your CRM is the source of truth for what's on your plate.

// 02

The calendar holds your day

Reality is divided into time blocks. If a task isn't on your calendar, it's competing with everything else for attention.

// 03

The gap is your time

The space between those two systems gets paid for in copy-paste, missed follow-ups, and "did we do that yet?" Slack threads.

Features

Built around one job, done relentlessly well.

Every feature exists to support a single promise: your tasks and your calendar always agree, without you doing the math.

// Two-way sync

Edit anywhere. Updates everywhere.

Change a task in HubSpot or move an event on your calendar — the other side catches up within minutes. No primary system, no losing direction, no manual reconciliation.

How it works

Three pieces. One quiet engine.

A small, reliable bridge that respects your filters and shows its work in an audit log you can actually read.

Source A

HubSpot

Tasks, due dates, owners, types, queues — everything your CRM tracks.

⇄

The engine

CalendarSplice

Watches both sides. Applies your filters. Writes an audit line for every decision.

⇄

Source B

Google or Outlook

Events appear, update, complete — exactly when they should.

Pricing

Honest pricing. One number.

Every customer gets the full sync engine, every audit, every filter. No basics gated behind tiers.

$15 a month, plus $2 per additional teammate.

That’s it. No setup fees, no add-ons, no “starter” tier missing the features you actually need. Save $24 a year on your base subscription with annual billing.
