A bit about how I work

I'm an operator who builds the connective tissue of early-stage companies: the governance, systems, and infrastructure that let a founder stay focused on the product while everything around it runs on rails.

Most engagements run the same arc, no matter which part of the business they're aimed at: I build the system, train the person who'll own it, work through the bugs that only show up once it's actually live, then step back. The exception is a retainer, which can continue for as long as it's useful, always as an external partner. See the FAQ or the engagement types on the homepage for the different ways to work together.

Why Anthos exists
The same three patterns show up in almost every founder-led company. Anthos exists to close them.

Across seven years operating inside early-stage companies, and more than twenty independent engagements since, the same pattern kept surfacing. It was never a bad idea or a weak product. It was what happened around the product while a founder's full attention was on building it.

01
Decision Overload
Founders losing weeks, sometimes months, to decisions that weren't actually about the product: hiring calls, vendor contracts, expense approvals, board dynamics, made by people whose entire training was building something no one had built before. An experienced operator resolves most of these in an afternoon. Left unresolved, they don't just cost a decision. They cost the founder's focus.
02
Confidence Drift
Capital changing how founders see their own odds. A raise, a strong quarter, or a favorable market cycle can quietly shift confidence into overconfidence, and caution into something read as weakness, until the market, the cap table, or the team corrects for it. The founders who keep their systems and accountability intact through the good months are the ones still standing when the good months end.
03
Passion Without Scaffolding
The most driven, highest-conviction founders are often the most exposed to this, because the unglamorous mechanics of running a company fall away while the vision takes over. Genuinely strong products fail not because the market rejected them, but because no one was minding the operational and financial floor while the founder built the ceiling.

The founders Anthos works with are high-intensity, deeply passionate, and building something worth the full weight of their attention. The work isn't to slow that down. It's to put the governance, systems, and people infrastructure, and discretion on sensitive matters in place so the company doesn't quietly come apart underneath the vision, and the founder's attention stays exactly where it belongs.

That's also why I don't become part of the team. I build each of these systems alongside the person who'll run them, and work through what breaks once they're actually load-bearing. Project work gets handed off to a named owner; a retainer can continue for as long as it's useful. Either way, I stay an external partner, never an employee, because the goal was never to make myself necessary. It was to make sure the company doesn't need anyone, including me, to keep running well.
