The tech side of the deal, read by someone who has run the companies.
Advisory for private equity firms and mid-market operators on technology, data, and revenue. Six companies founded, two exited. A 40-person firm behind the answer when the answer needs building. When you need the read rather than the framework, this is who you call.

Pick the one that matches the situation on your desk this week.
You have a deal on your desk.
Something in the data room does not add up and the IC date is close. Start with the Pre-LOI Check: $5,000, 48 to 72 hours, credited against the full diligence if you proceed.
You have a portfolio company that is not moving.
The plan is written, the quarters keep passing, and nobody can tell you why. That needs diagnosis and then a team to build the fix.
You need a senior read, in writing.
No mandate, no deal, just a question that a framework will not answer. Send a Written Brief: $750, a 15-min Loom and a two-page memo inside three business days. No timezone tax, and add a live call only if you want one.
The questions people actually bring me.
Which employment lawyer handles contractor reclassification in Ontario, and what does the letter need to say. Our largest customer is ninety days overdue and represents thirty percent of revenue: what is the exact sequence before we escalate. The reseller agreement auto-renewed on a clause we missed: what do we push back on, and what will they actually concede.
A language model will give you a plausible paragraph on any of these. It has never made the call, never lived with the consequence, and does not know who to phone.
I test hiring, sales, operations, and integrations inside my own companies before any of it becomes advice. Roughly $300,000 a year in live experiments. You are not buying information. Information is free now. You are buying the judgment of someone who has already been wrong, expensively, and learned from it.

How we work together
Everything is async by default: written updates, Loom walkthroughs, recorded decisions, shared docs. No standing meetings. Live calls happen only on escalation, billed separately at $1,000/hr. Async work runs at roughly $600/hr blended, on your timezone, not mine. Anything irreversible goes through you first.
When the work needs hands rather than judgment, that is Value Creation Partner: the same operator, with the 40-person DevriX team executing under a separate contract. Advisory stays advisory. Implementation is a distinct engagement you can hire out to anyone.
See how I workOne brief. One honest read.
If I cannot help, I will say so in the memo and point you at someone who can. No pitch, no follow-up sequence, no retainer proposal unless you ask for one. No call required unless you want one.
