Transparent, Project-Based Pricing

No surprises. Clear scope, clear acceptance tests. We believe in straightforward pricing so you know exactly what to expect before we begin.

A failed integration is more than a technical problem: it's a drain on time, budget, and morale. We are the specialists that leading companies like MetLife trust to handle their most mission-critical data flows. We don't rely on fragile connectors or simplistic platforms because we know they can't handle enterprise scale. Our approach is built on robust, custom development and a deep understanding of both HubSpot and the systems you need to connect it to. Partnering with us isn't just another attempt; it's an investment in certainty.

Why Integrate IQ?

Our four pillars for delivering successful outcomes on complex projects.

Mastery of Complexity

We thrive on custom API integrations, multi-system migrations, and “messy data” that makes others pause. Full support for standard and custom objects across your stack is table stakes for us.

Pragmatic Innovation

Real problems, shipped solutions. Our proprietary Smart Ramp apps were developed to fill gaps in HubSpot capabilities and solve real-world customer problems. The same practical mindset powers our HubSpot AI Accelerator: We focus on data readiness and shipped outcomes, not shiny features.

De-Risking the Process

Complex projects demand clarity. Our Smart Process runs on an 8-12 week cadence with stage gates, transparent deliverables, and clear pricing. That’s how we maintain a 98.5% customer retention rate.

The Expert You Call

We’re a developer-led team of integration engineers, solution architects, and technical PMs. Clients describe us simply: 'the folks you call when something seems impossible.'

I've been working with Integrate IQ for over 2 years now. We've had several outside systems that we wanted integrated with our HubSpot instance. From project planning and scoping, through build, and after deployment support, the team at Integrate IQ has been exemplary to work with. They've delivered on all commitments, helped established reasonable time frames for deliverables, and kept lines of communication open.

Marohn, M

We've partnered with Integrate IQ for over five years to develop integrations between our complex and not-so-widely-known ERP. They understand HubSpot's strengths, weaknesses and limitations, and are able to easily adapt to our evolving needs. They had an ownership change a few years ago, but that did not impact their expertise/service. We really appreciate our relationship with IIQ and recommend them to anyone looking to embed HubSpot deeper into their organization's systems.

Craychee, A

Integrate IQ has been great to work with! As someone who can be intimidated when things get too technical, they made the process of outlining our integration very approachable and understandable. They're great to work with and built the integration that we asked for, and then continued to work with us to fine-tune the tool over time as we figured out exactly what we needed.

Lauren Little

Integrate has been fantastic to work with. They helped us implement our CRM, design a framework for our pipeline that works perfectly and they built out an integration between HubSpot and Netsuite which allows our data to flow seamlessly. They've been an invaluable partner in our growth.

We worked with Integrate IQ on a complex integration and now we have a fantastic solution that makes HubSpot work even better!

Frequently Asked Questions

We utilize advanced email matching logic. If a prospect already exists in HubSpot, we simply update their record with the latest campaign activity rather than creating a duplicate, keeping your database clean.

Absolutely. You can set up triggers so that a "Reply" or specific "Lead Category" (e.g., "Interested") in Smartlead automatically enrolls the contact in a HubSpot nurture sequence or creates a task for an account executive.

Yes. Unlike native connectors that only "listen" forward, we can perform a historical backfill to ensure past campaign data and engagement metrics are accurately reflected in your HubSpot CRM.

No. You can configure the sync logic to filter out auto-replies and non-human interactions, ensuring your sales team only sees genuine engagement in their activity feeds.
