20 minutes · $10 · Credited to anything you buy

Not sure which one you need?
Ask the engineer.

Twenty minutes with a Centenum co-founder. Show us what you have built or what is going wrong, and we will tell you what is actually happening and recommend exactly one next step. The $10 holds your slot and is credited in full to anything you purchase. If nothing we sell fits your situation, we will say so, and the honest answer is yours to keep.

Book your triage call

You talk to a founder, not a salesperson: a PhD engineer and Y Combinator alumnus who has shipped production systems in fintech, healthcare, and government for over a decade.

How the call works

Three things, in twenty minutes.

01
You show, we look
Bring the product, the repo, the website, or just the problem. The first ten minutes are yours.
02
We diagnose, live
You will hear what is actually wrong, or actually fine, in plain language, while you watch us look at it.
03
One recommendation
You leave with exactly one next step and a link. Not a menu, not a proposal, not a follow-up sequence. One step, and your $10 already paid for part of it.

Before the call

Four quick questions at booking.

So the engineer arrives knowing your situation. About a minute total.

01. What did you build, or what are you trying to fix?
One or two sentences.
02. What is it built with?
Cursor or Claude Code; Lovable, v0, Bolt, or Replit; a development team or agency; WordPress, Webflow, or similar; other.
03. Is it live?
Not yet live; live, under 100 users; live, over 100 users; live, with paying customers.
04. What do you spend monthly on AI or API usage?
Nothing yet; under $500; $500 to $5,000; over $5,000.

The fine print, plainly

No tricks. No upsells in disguise.

The $10 is credited in full toward anything you buy, from the $597 teardown to a full engagement. It is not refunded if you buy nothing; it is the price of holding a senior engineer's time.
Slots are capped at eight per day across both founders. When the day is full, it is full.
You can reschedule once at no charge with at least four hours' notice. No-shows forfeit the $10.
Everything you show us is covered by NDA from the moment you book.

FAQ

Questions, answered.

Why charge $10 at all?

Because the call is with a founder, not a setter, and ten dollars is the difference between a calendar full of curiosity and a calendar full of builders. You get it back the moment you buy anything, so for everyone serious, the call is free.

Will this be a sales call?

It will be a diagnosis. You will get one recommendation at the end because that is what a diagnosis is for, and the recommendation will sometimes be "you do not need us yet." We put that in writing here so you can hold us to it.

Can I skip the call and just buy?

Yes, and if you already know what you need, you should. The teardown, the rescue sprint, and the visibility audit all check out directly, no call required.

What should I have ready?

Whatever shows the situation fastest: a link to the product, the repo, your website, or a screen recording of the problem. The booking questions cover the rest.

Twenty minutes. One honest answer.

Pick a slot, answer four questions, and bring what you have built.

You will leave knowing exactly what to do next, whether or not it involves us.
