The bench behind every engagement.

Operating executives, leading through direct execution. Every engagement draws on the same four capabilities: CTO, COO, project and program leadership, and AI guidance. Founder Advisory and an ARGUS assessment determine which of them your project needs.

Built by AltoLumo

ARGUS Assessment

The AltoLumo method for guiding a project from concept to execution: reading where it stands today, mapping the phases ahead, and determining which capabilities, CTO, COO, or program leadership, the work actually calls for.

Wence GutierrezFounder, Irongrove
A CLI turned into a production MVP with paying customers.
When Ken Benavides joined Irongrove, we had a working command-line product and a clear north star: a subscription-based product our customers could sign up for and rely on. What we needed was the front end, application stack, development team, and operating discipline to get there. That is the gap Ken came in to fill. Through AltoLumo, on a fractional basis, he helped us assemble and direct our engineering team, establish our sprint cadence, delivery workflows, and governance, and lead the work that turned our CLI into a production MVP with paying customers. We were working with a short runway, so he kept the team focused on delivering an MVP that could grow into the subscription platform we set out to build. At the same time, he helped us launch the product line with packaging, go-to-market strategy, and customer onboarding built in. While the product was being developed, he also scoped consulting engagements and helped structure the commercial work that supported the company along the way. Ken has stepped into whatever role we needed at the time, advisor, CTO, COO, and he still leads client engagements himself. Ken does not advise from the sidelines. He builds the company with you.

05 · The Practice Behind It

One firm. Strong partnerships.

Strategy Defined. Results Delivered.

We collaborate, bringing the AltoLumo team together with trusted partners scaled to the size of your project, working alongside clients on the technical problems that matter most to their business. Working as one team, not a roster of strangers: assessing what needs to change, building the structure, and running the execution until your organization can sustain it on its own.

07 · Questions, Answered

Frequently asked questions.

What is a fractional CTO or COO, and how is it different from hiring full-time?

A fractional CTO or COO gives a founder executive-level technology and operations leadership without a full-time hire. AltoLumo works alongside your team on the schedule your stage actually needs, from a few hours a week to embedded full-time, scaling up or down as the work changes.

What does AltoLumo actually do for a client?

AltoLumo works at a strategic level, consulting alongside founders and their teams to steer a product toward market and build what gets it there. Every engagement runs on the same throughline: discover what the business actually needs through direct work with the team, refine the plan and the roadmap as real constraints surface, and deliver a working outcome, whether that's a platform, a program, or an aligned team ready to execute. Websites, applications, custom development, infrastructure, and portals are examples of what gets built along the way, not the whole of the work.

What does an AltoLumo engagement include?

Every engagement is scoped around what the work calls for, from CTO, COO, and Project & Program Leadership to AI Guidance, brought together into the capabilities each project actually needs.

Where is AltoLumo based?

AltoLumo is based in Houston, Texas.

How does a project start?

Every engagement starts with an initial discussion to understand the opportunity.

Does AltoLumo use AI in its engagements?

AI is brought in when the project requires it.
