You've built something real. Now it's plateaued because the next level requires systems your team can't build alone. That's the gap I fill.

01 · The Cost of No System

You're not running a business. The business is running you.

If you're a $1M–$10M business owner in Quintana Roo, Yucatán, or anywhere in Mexico, here's what your week actually looks like.

Monday morning, your phone buzzes before 7am. Three customers DMing in WhatsApp. Two suppliers asking for confirmations. Your team needs schedules approved. The accountant wants invoices. You haven't even had coffee.

By Friday, you've spent 40+ hours doing work that isn't building your business — it's just keeping it from falling apart. Customer service, scheduling, follow-ups, manual data entry, repeating the same answers fifteen times a day.

Meanwhile, the things that actually matter — strategy, growth, your family — get the leftovers. The energy you have left at 9pm. The weekends you said you'd take but never do.

Most owners assume this is just what running a business in Mexico costs. It isn't. It's what running a business without a system costs.

Three businesses in Playa del Carmen, Tulum, and Cancún already replaced this chaos with systems that run themselves. You could be the fourth. Or you could keep paying the cost — in hours, in revenue, in the relationships you're not present for.

02 · The Window

The window is open. It won't stay that way.

Right now, fewer than 5% of Mexican businesses in the $1M–$10M range have AI systems running their operations. The other 95% are still doing it the old way — manually, by spreadsheet, on email, in WhatsApp groups that nobody fully reads.

That gap is the opportunity. The businesses that build AI-powered operations in the next 12 to 18 months will compound that advantage for the rest of the decade. The ones that wait will spend the next five years catching up to systems their competitors already have.

This isn't theory. We've seen it happen with every previous technology shift — the internet, e-commerce, social media. The first wave of adopters captured most of the available market. The second wave fought over scraps.

From Mexico City to Mérida to the Riviera Maya, the businesses building AI-powered operations now will define the next decade in their markets. Your competitors aren't there yet. They will be — but probably not this year.

The question isn't whether AI will run Mexican businesses. It's who builds the system first: you, or the business you're competing against.

02 · The Vision

Imagine knowing exactly what your business is doing — every order, every message, every follow-up handled without you.

Not faster. Not cheaper. Different. A business that runs while you sleep, while you're with your family, while you're growing the next thing. This is what we build.

03 · Autonomous AI Workflows

AI lets your business run without .

WhatsApp answered. SAT compliant. Opportunities found. Social media posted. Schedule managed. Pulse measured. Every one of these used to be your job. Now it's the system's.

07 · Beyond Operations

Operations is where it starts. It's not where it ends.

The same architecture that replaces your manual operations also runs your sales funnels, your lead nurturing, your CRM automation, and your customer follow-ups. AI doesn't care whether the bottleneck is a WhatsApp message, a sales lead, or an investor inquiry — the system handles all of it the same way.

Three months in, the conversation usually shifts from "how do we automate operations?" to "what else can this run?" That's when the real compounding starts.

08 08 · Real Engagements

Same architecture. Different functions. Real results.

Tulumi is based in Playa del Carmen and works with established businesses in Mexico and beyond. The architecture is portable — these engagements span operations transformation, knowledge-work team augmentation, and sales infrastructure.

FAQ

Common questions about Fractional AI CTO engagements.

What does a fractional AI CTO actually do?
A fractional AI CTO provides senior technical leadership without the cost or commitment of a full-time hire. At Tulumi, that means strategy, hands-on implementation, and ongoing system ownership for AI-powered operations. Engagements typically include WhatsApp automation, custom dashboards, AI chatbots, integrations with your existing tools, and team mentorship — delivered as an ongoing engagement starting at $80,000 MXN with first measurable results in around three weeks, then continued via monthly retainer.
How much does custom AI software cost in Mexico?
Custom AI software and Fractional AI CTO engagements at Tulumi start at $80,000 MXN (approximately $4,500 USD) for the initial architecture and infrastructure phase. Ongoing fractional AI CTO retainers are $50,000 MXN per month. Final pricing depends on integration complexity — number of systems to connect, custom AI workflows required, and team training scope. We provide a fixed quote after a free 30-minute scoping call.
How is this different from hiring a full-time CTO?
A full-time CTO in Mexico costs $250,000-$500,000 MXN per year fully loaded, plus equity, plus a 6-month hiring process. A fractional AI CTO at $50,000 MXN per month gives you C-level technical leadership starting in week one, with no equity dilution and a month-to-month commitment. For businesses in the $1M-$10M revenue range that need senior AI guidance but aren't ready to absorb a permanent executive hire, fractional is the right fit.
What size business is this for?
Tulumi's Custom Software and Fractional AI CTO services are built for businesses with $1M-$10M in annual revenue running operations on email, spreadsheets, or fragmented SaaS tools. Typical clients are hotel groups, restaurant chains, tour operators, transfer companies, clinics, and wholesale operations. If you're processing 100+ orders or bookings per day and the operator is the system, you're our target.
What does the engagement timeline look like?
Weeks 1–2 are discovery and architecture — mapping your current operations, identifying bottlenecks, and designing the system. Weeks 3–4 you start seeing first measurable results as the initial AI workflows go live. From month 2 onward, we keep building, expanding what the AI runs, and optimizing. There's no end date — the engagement continues as long as it's creating value, month-to-month, with you owning everything we build.
Do you work with US-based companies operating in Mexico?
Yes. A significant portion of our client base is US-owned hotels, tour operators, and businesses with operations in Mexico. We're fully bilingual (English and Spanish), based in Playa del Carmen, and routinely handle compliance with Mexican tax authority (SAT), CFDI invoicing, and bilingual customer-facing systems. We work with US time zones, accept USD invoicing, and integrate with US-based tools like QuickBooks, Stripe, and HubSpot.
What if our team is non-technical?
Most of our clients are non-technical. The whole point of fractional AI CTO is that we own the technical layer so your team doesn't have to. Deliverables include plain-English operations playbooks, integration runbooks, and dashboards your team uses without writing code. Training is included in the initial engagement phase, and ongoing retainer covers any technical questions or troubleshooting.
What stack and tools do you use?
We build on production-grade stacks: Next.js, Supabase/Postgres, Vercel, Cloudflare R2, Anthropic Claude and OpenAI GPT models for AI workflows, WhatsApp Business API via Meta Cloud API, n8n for automation orchestration, and integrations with whatever tools you already use — QuickBooks, Stripe, ServiceTitan, Jobber, Mercado Pago, and others. The architecture is documented and portable; you're never locked into a proprietary system.
How is this different from a traditional dev agency?
Traditional dev agencies build what you ask for and disappear. A fractional AI CTO owns the technical strategy, makes architectural decisions, and stays embedded in your business. We're not selling you hours; we're selling you outcomes — fewer manual operations, more revenue captured automatically, and a system that runs without you. The engagement is a real product launch and ongoing partnership, not a project handoff.
How long does the engagement typically last?
Most engagements continue 12–24+ months because the AI workflows compound — the more your team uses them, the more we can optimize, and the more functions become candidates for automation. Some clients keep me on indefinitely as their ongoing CTO. Others move to a maintenance-only arrangement after 18 months. Some add additional projects that scope into separate engagements. The retainer is month-to-month — you decide each month whether to continue.
Do you also handle our marketing or run ads for us?
No. I'm the technical architect — I build AI systems, integrations, dashboards, and operational infrastructure. Ad campaign management, paid media buying, and content marketing are typically handled by separate partners. Most of my clients have those covered. If you don't, I can recommend trusted partners. Keeping the technical and marketing roles separate produces better outcomes for both.

If you're a $1M–$10M business in Mexico running operations on email and spreadsheets — this is the system we'd build for you.

Same architecture works for restaurant chains with 200+ orders/day, hotel groups managing direct bookings, clinics processing patient intake, transfer companies juggling reservations across 3 platforms. The surface changes. The math doesn't.
