Less Than Half the Cost of Hiring.

Most companies choose between a $250k/year CTO hire, a $30k–50k/month agency, or a patchwork of freelancers. Interspark is the alternative — four plans from $2,000/mo for solo founders to $14,000/mo for scaling teams. No long-term contracts required.

Frequently Asked Questions

What's included in each plan?

Every plan includes senior development hours, a dedicated developer you can reach directly by phone, Slack, or email, acceptance-driven delivery, and a 30-day cancellation policy. No ticket queues, no account managers — you talk to the people doing the work. Solo and Starter focus on development capacity. Growth and Scale add CTO-level strategy hours — architecture reviews, technology roadmapping, UX/UI direction, and vendor evaluations.

What does CTO-level strategy actually cover?

Architecture reviews, technology roadmapping, UX/UI direction, vendor evaluations, and board-ready technical assessments. It's the thinking that usually requires a $250k hire. Growth includes 10 hours per month, Scale includes 20 — integrated with the team doing the building.

What happens if I need more hours than my plan includes?

Overage is billed at a flat per-hour rate that depends on your tier — from $135/hr on Scale to $175/hr on Solo. We'll always flag it before going over so there are no surprises on your invoice. If you're consistently going over, it usually makes sense to move up a tier for a better rate.

How is this different from hiring an agency?

Agencies sell you a process and staff it with whoever's available. We give you a consistent senior team — no account managers, no juniors learning on your dime. The people setting the technical direction are the same people writing the code.

Can I switch plans or cancel?

Yes to both. Upgrade or downgrade with 30 days notice. Cancel anytime with 30 days notice — no penalties, no exit fees. We keep working through the notice period so nothing falls on the floor.

How senior are your engineers?

Every engineer averages 10+ years of professional experience, team leads 15+. You will never be staffed with junior developers. That's not a sales line; it's how we operate.

The math is straightforward. Let's walk through it.
