Portrait of Alejandro Vásquez

Growth & Marketing Engineer / Mexico City

Alejandro Vásquez

Performance marketing and funnel optimization for tech companies with traction.

I help companies that are already spending—or preparing to spend—more than $10K a month on acquisition but do not yet have enough senior growth expertise in-house.

I connect campaigns, positioning, offers, landing pages, product experience, and measurement to find the friction slowing growth and turn it into experiments that produce measurable results.

About me

I'm a Growth & Marketing Engineer and the founder of Thinklab.co.

For more than 10 years, I have helped tech companies across the US and Latin America acquire users, improve their funnels, and make better growth decisions.

My work combines performance marketing, product marketing, experimentation, and analytics. I can diagnose problems inside the campaigns, but I also step in when the real friction is in the positioning, offer, landing page, pricing, activation, or measurement.

I have advised more than 40 startups, led go-to-market for over 20 apps and e-commerce businesses, managed $200K per month in paid media at 4X ROI, and built a remote growth team of 10 people.

I have worked across B2B enterprise software, fintech, AI, mobile apps, e-commerce, and performance agencies. The industry changes, but the situation is often similar: the company has traction and is investing in growth, but marketing, product, and analytics are not operating as one system.

Outside of work, I spend a lot of time journaling, hiking, and meditating.

Working with me

The best fit is usually a founder or lean growth team at a tech company with traction, an acquisition budget, and no senior growth leader in-house.

Most projects start with a diagnosis of the growth system: campaigns, positioning, offers, creative, landing pages, tracking, funnel behavior, and actual conversion quality.

From there, I prioritize the changes most likely to improve acquisition, conversion, or revenue. Depending on the problem, I can execute directly, work alongside the internal team, or coordinate the specialists already involved.

Clients are typically spending, or preparing to spend, at least $10K per month on acquisition. Many are early-stage companies that have raised between $500K and $3M. Others are bootstrapped and funding growth through revenue.

I work async-first and stay close to execution. We can start with an audit, work through a defined optimization project, or continue through a fractional engagement.
