Results That Speak for Themselves
"Khristian was excellent at quickly understanding my client's desired workflow. He produced two custom integrations well ahead of time with zero issues since implementation — showing an ability to understand complex briefs quickly, deliver well-constructed integrations, and communicate in plain language."

Frequently asked questions
What does ArcHub Solutions do?
We're a HubSpot Solutions Partner that architects and builds custom HubSpot solutions. We design the strategy, then implement it through custom coded integrations, workflow actions, serverless functions, and API connections that make your systems work together seamlessly.
Do you just build what we tell you to build?
No—we start by understanding your business challenges and goals, then architect a solution that actually solves the problem. Many clients come to us saying "I need X integration" when what they really need is "Y workflow redesign + Z data structure + X integration." We help you figure that out first.
What types of integrations do you build?
We connect HubSpot to accounting systems, custom databases, proprietary software, and any system with an API. Common projects include bi-directional data syncs, custom workflows, automated document generation, and advanced deal/renewal automation.
Do you provide ongoing support after the integration is built?
Yes - through our retainer packages or on-demand hourly support. We recommend retainers for clients who need regular maintenance, updates, or ongoing development.
How do you charge for projects?
Fixed-price projects are scoped upfront — typical range is $1,500–$10,000 depending on complexity. White-label retainers are billed monthly at $100–$150/hr. All projects require a 50% deposit to begin.
