Stop renting softwareOwn your stack

We build one custom AI system that replaces the SaaS tools and manual busywork your team pays for every month, then we hand you the code and get out of the way. One job ships in 2 to 4 weeks, one system in 4 to 6.
No seats, no renewal, no monthly tax.

Client Stories

Nina Lubrasky

Owner, Humm House

Totally worth it. Dan is so communicative, timely and helpful. I felt confident in the process and their delivery.

They were very clear about expectations, pricing and timing, and delivered on all those aspects. I would highly recommend them!

Stefan H.

Founder, Talentbridge

There was a backend guy one of my recruiters sent over on a Tuesday who I didn't get to until the Monday. He'd taken something else by then. I only found that out because I emailed him to set something up.

Everything that came in went to whoever owned that vertical, but somebody had to open the PDF first and read down it for the role, and she'd worked out that was 11 hours a week between us. Radu still prints them out before he'll read them, which Ana keeps telling him he doesn't need to do.

A friend of mine had used Dan for something else and said they were easy to deal with, which is mostly why we reached out. Getting to a scope was quick, one call and then a short doc back, no drawn-out discovery thing, which suited me because I don't have the patience for it. It was invoice approvals we got them in for, sounds boring and was, but it was costing us real money. What used to happen is an invoice lands in the general inbox and sits there, because whoever opens it isn't the one who signs it off, so it gets forwarded on, usually to the wrong person first, and by then you're weeks past. Cristina got a lot of stuff that had nothing to do with her.

Now it goes straight to whoever has to approve it and they get it in Slack with two buttons on it. That's more or less it. Was averaging 6.2 days before, I've got that written down somewhere.

Sarah Chen

RevOps Lead, RevSync

We had a ratio problem I could see in the numbers and couldn't do much about. Half the names on the demo list every week were companies we were never going to sell to, and the other half were a genuine fit that we lost while our SDR was still grinding through the first pile.

They put a step in front of the form so everything gets checked against our ICP rules before it reaches a person, and the ones that clear go straight to our AE while he can still do something useful with them. It was $4k. I look at first touch every Monday out of habit and it's sitting around four hours, against 19 before we did this.

Priya R.

Founder, Forekast

I nearly killed the project early on, which I don't love admitting. We were paying $49 a month for Copy.ai Pro and still losing four hours a brief to research, so I took that as proof the whole category was oversold. Or I'd already decided it was and went looking for evidence, more likely.

Then I was standing behind Nadia while she had one of the outlines up, and it was better than the thing I'd been about to cancel. You feed it an angle, it comes back with an outline and the source links underneath, and it tells you which hook it thinks is strongest. Reddit, HN and Perplexity, going by what Dan said when they set it up.

The biggest change was speed. We were able to ship things in parallel much faster, while keeping our internal team focused on other priorities.

The best part was being able to trust them with the work and not having to manage every small detail. Communication was easy, feedback was handled quickly, and they were always open to changing the approach when needed.

Two Lanes

One gets the recurring work done. The other gets the recurring bill off your books. Both end with nothing left to renew.The tooling we build on is public at github.com/dancolta. Read the code before you talk to us.

Lane 01 · €3,000 max

Automate your daily ops

Work that only gets done when somebody remembers.We build the thing that does it for you.It is yours to keep.One hour a day is 250 hours a year.The number is a ceiling rather than a price so the only direction it can move is down.

Lane 02 · €6,500 to €24,000 max

Replace your SaaS

You rent five tools and use a bit of each.We build one you own and the renewals stop.Five tools at €200 a month each is €12,000 a year, every year.Replacing the whole stack is €14,000 to €24,000 max and it never renews.The number is a ceiling rather than a price so the only direction it can move is down.

What We BuildAnd What It Costs

NodeSparks is a founder-led AI automation agency for SMEs. We build custom agents and automations for the work that eats a week: outreach, reporting, lead capture, internal handoffs and candidate routing. Two senior operators write the code.

Every number is a maximum rather than a fixed price. You are billed monthly on the hours the build actually takes and the invoice never passes the number in the scope. Fewer hours and you pay less. The 30 minute call is free. So is the written scope. It is yours whether you hire us or not.

Nothing is paid before work starts. The repository, the deployment and the API accounts go into your name on final payment. You can stop at any point and pay only the hours worked. We will not automate a process nobody inside the business has agreed on yet. We say so on the call.
