HubSpot · Company
HubSpot is only as good as the data flowing into it.
Most revenue teams don't have a HubSpot problem. They have a connection problem. HubSpot can't see the tools where the rest of the business runs, so the records go stale. Sound familiar?
HubSpot doesn't know what customers pay
Stripe, Chargebee, and your invoicing live outside HubSpot. So MRR, renewal dates, and payment status are guesswork on the deal and company records that reps actually look at.
Someone re-keys data by hand every week
A rep or ops hire copies numbers from your product and billing tools into HubSpot properties. It's slow, it's wrong by Friday, and it does not scale with headcount.
Forecasts run on stale properties
Pipeline and revenue dashboards read from fields nobody kept current. The number in the board meeting is already out of date before anyone opens it.
Native apps and Zaps break quietly
A field mapping fails at 2am, no one owns it, and you find out when a customer does. A rigid marketplace app or a chain of Zaps has no one watching it.
We build the integration your setup needs, then we keep it running.
StackTie is a productized service. We design, build, and maintain a custom HubSpot integration fitted to your exact stack, then we own it. So it never silently breaks and you never think about it again.
The StackTie way
- Fitted to your HubSpot setup, not a template
- Two-way sync, with the edge cases handled
- Verified live against your real records
- One owner who monitors and maintains it
- Kept stable and fixed before a break reaches you
The alternatives
A native marketplace app
Fits its own data model, not yours. You bend your pipelines and properties around its limits.
A generalist agency
Months of scoping and a big invoice from a team that has never lived inside HubSpot.
A freelancer
Ships it, moves on, and it becomes your problem the day it breaks.
A stack of Zaps
Fine until volume or an edge case hits. Then it fails silently with no one on call.
Three steps. Most of the work is ours.
From the first call to a live, monitored integration. Here is the whole process.
- 01
Free audit call
We look at your HubSpot portal and the tools around it, then show you exactly where data is leaking or getting re-keyed, and what a fix looks like. No cost, no obligation.
- 02
We build it
We build the integration, handle the edge cases, and verify it live against your real records. Done in 14 days. You don't pay until it works and you've confirmed it.
- 03
We monitor and maintain
We watch it in production and fix anything that breaks, usually before you notice. It keeps working as HubSpot and your other tools change.
Live in 14 days, or you don't pay.
This is our single biggest promise, and nobody else on the market makes it. Pay nothing until your integration is live and you have confirmed it works. If it is not running within 14 days, the build is free. We would rather carry the risk than ask you to.
- You confirm it works before any money changes hands
- Not live in 14 days? The build is free
- The monthly retainer only starts once you're happy
Not “an integration.” All of this.
Every engagement includes the build and the upkeep. Here is what you actually get.
Custom field and property mapping
Your objects, properties, and pipelines mapped to the other system exactly the way your team already works in HubSpot.
Two-way sync
Changes flow in both directions and stay consistent. No winner-takes-all overwrites, no records drifting apart.
Edge cases handled
Deletes, merges, deduping, rate limits, and retries. The weird records that quietly break naive integrations.
Live monitoring
We watch it in production and get alerted the moment a sync fails, usually before it ever reaches your team.
Ongoing maintenance
When a HubSpot or vendor API changes, or your process shifts, we update the integration. It is ours to keep running.
A direct line to us
One accountable owner you can reach when something looks off or your team needs a change. No ticket queue, no handoffs.
One build fee. One monthly retainer.
Transparent by design. You pay once to build the integration, then a flat monthly retainer to keep it monitored, maintained, and improving. No hourly billing, no surprises.
One-time build
$4,000
Charged only once it's live and you've confirmed it works.
Then monthly
$1,000/mo
Monitoring, fixes, and updates that keep it stable. Cancel anytime.
- Custom field mapping and two-way sync
- Edge cases handled and verified live
- Live monitoring so breaks get caught fast
- Kept stable as HubSpot and your tools change
Live in 14 days or it's free
Multi-system or high-volume builds are scoped and quoted from the build fee above.
Proven demand. Proven delivery.
“We were about to pay an agency thousands for a custom HubSpot integration. Turns out the team behind the app we already used could just build it.”
Live on the HubSpot Marketplace
We publish and maintain our own app on the HubSpot App Marketplace. The same rigor goes into every custom build.
Founder-led and accountable
You work directly with the person building your integration. One owner, one point of contact, no handoffs.
14-day delivery guarantee
Live in 14 days or you don't pay. The risk sits with us, not with you. Few services will put that in writing.
A specialist, not a generalist.
The difference between an integration that lasts a quarter and one that lasts for years is who is behind it.
HubSpot is all we do
We don't dabble across every CRM and platform. HubSpot integrations are the entire business, which is why we move fast and hit the edge cases a generalist agency would not know exist.
We build products, not one-offs
Because we ship our own marketplace apps, your build stands on battle-tested integration code, not a from-scratch experiment you are paying to debug.
Maintenance is the product
A freelancer's job ends at delivery. Ours starts there. The monthly retainer means someone is always accountable for keeping your integration alive.
Questions, answered.
Everything you need to know before the call.
Stop your HubSpot data from drifting.
Book a call and we will audit your HubSpot setup, show you exactly where data is leaking, and tell you what it takes to fix it. No cost, no pressure. And if we build it, you pay nothing until it works.
