6sense HQ vs Arc.Dev:Complete Product Team vs Vetted Developers

Arc.dev is best when you already have technical leadership and need a vetted developer to join your team. 6sense HQ is built for founders who need a complete product team with architecture, development, QA, design, and project management included. If you are a non-technical founder building your first SaaS product, 6sense HQ handles what Arc.dev leaves you to manage yourself.

A complete product team at 6sense HQ includes a Fractional CTO, senior developers, a QA engineer, a UI/UX designer, and a dedicated project manager. Every role works within the same sprint process with one shared delivery goal. Instead of coordinating multiple contractors or hires, you get a single team responsible for taking your product from concept to production.

Arc.dev developers typically cost between $60 and $80 per hour, plus platform fees, and engagements are generally structured around individual hires. 6sense HQ offers fixed-price builds starting from $40,000, dedicated product teams from $5,000 to $15,000 per month, and hourly support from $20 to $35 per hour. Pricing is agreed before work begins, with no placement fees or hidden markups.

Yes. 6sense HQ is specifically designed for founders without an internal engineering team. Your Fractional CTO handles technical strategy and architecture decisions, your project manager coordinates delivery, and the development team manages implementation and QA. You stay focused on product vision, customers, fundraising, and growth while maintaining full visibility into progress.

Arc.dev can typically match developers within a few days, making it a fast hiring platform. 6sense HQ can onboard a complete product team within 48 hours after a discovery call. That includes a CTO, developers, QA, design, and project management, allowing your first sprint to begin immediately instead of spending time assembling and managing separate resources.

If a team member is not the right fit, 6sense HQ replaces them within 48 hours at no additional cost. Team continuity and delivery momentum are prioritized, so replacements are handled without disrupting the project. With a documented process and a 91% retention rate, founders can move forward confidently without restarting the hiring process.

Yes. 6sense HQ uses AI-assisted tools across development, testing, and documentation to improve efficiency and reduce repetitive work. Every AI-generated output is reviewed, tested, and validated by senior engineers before deployment. While Arc.dev uses AI to help match developers, 6sense HQ uses AI throughout the product delivery process to accelerate execution without sacrificing quality.

Arc.dev works well when you already have internal product and engineering leadership managing long-term development. 6sense HQ is often a stronger fit for founders who want continuity across planning, development, launch, and post-launch growth. The same team retains product knowledge, supports new features, handles maintenance, and helps scale infrastructure as the business grows.
