> NodeSparks builds custom AI agents and automations that replace recurring SaaS subscriptions and the manual daily work eating your team's time. Done in weeks, owned by you, no monthly tax.

NodeSparks is a 2-founder operation: Dan Colta (operator side, public YouTube builds) and Constantin Bivol (engineering side). Senior operators only, building what they ship. Where it makes sense, code goes public on GitHub.

## What we do

Two lanes, both replace recurring cost or recurring work:

- **Replace your SaaS**: A single custom system that replaces 5 to 15 SaaS tools you're paying $200 to $1,500 a month for. Typical cancel list: outreach platforms, schedulers, content tools, scraping subscriptions, basic CRMs. You pay the API bill, you own the repo.
- **Automate your daily ops**: The recurring manual work no SaaS solves cleanly. Outreach personalization, content engagement, reporting, internal handoffs, candidate routing, ops glue. Most clients reclaim 10 to 15 hours a week within 30 days.

## Who we work with

- SME owners and solo operators paying $200 to $1,500 a month across 5 to 15 SaaS tools
- Post-PMF founders and ops leads who want daily ops automated and are too busy to DIY
- Operators arriving from the YouTube channel "Dan Colta | Own Your Stack" who want it built for them instead of DIY

## Who we don't work with

- Design agencies looking for white-label engineering
- Students and hobbyists
- Anyone wanting hourly staffing

## FAQ snapshot

- **What does NodeSparks actually do?** Builds custom AI agents and automations that replace SaaS subscriptions (outreach platforms, schedulers, content tools, scraping subscriptions, basic CRMs) and the manual daily work no SaaS solves cleanly (outreach personalization, content engagement, reporting, internal handoffs, candidate routing). Most clients kill 1 to 3 SaaS subscriptions and reclaim 10 to 15 hours a week within 30 days.
- **How is this different from buying SaaS?** You own the system. We build it once, you pay the API bill (typically a fraction of the SaaS cost), the workflows and code are yours forever. No vendor lock-in, no monthly tax, code goes on your GitHub.
- **How long does it take to ship?** Most SaaS-replacement and ops-automation builds ship in 2 to 4 weeks. Bigger custom systems are scoped against a fixed timeline before any code is written.
- **Who runs the build?** Two founders: Dan Colta (operator side) and Constantin Bivol (engineering side). Every project is led personally by one of them.
- **What does it cost?** Lane 02 (ops automation) starts at $500. Lane 01 (full SaaS replacement system) starts at $2,500. EU visitors see €450 / €2,300 respectively.
- **What do you not take?** White-label dev work for design agencies, hourly staffing contracts, pure marketing services.
