Silicon Valley style business English for your next demo, interview, or investor call.
Free courses and an AI coach. Not generic grammar. The English of US tech work. Mike Sullivan coaches this: 30+ years in technology sales and consulting, TESOL-certified, based in Colombia.
Your coach
Mike spent 30+ years in technology sales and consulting, then got TESOL-certified to teach this.
He built SV English for Latin American founders, engineers, and operators who already have the work, and need the English to match. The lessons come from standups, demos, client calls, and investor updates.
If you are also building a company, the GTM and 60-day founder programs sit next door, including Spanish and Portuguese editions.
The clip uses a public-company number to make the structure obvious. Steal the move, not the scale. Use a fact you could actually research for the company in front of you.

The second candidate changes the conversation.

Rehearse
Build a short brief, speak it aloud, and get feedback from Alex or Mike.
Apply
Use the revised language in the real conversation, then improve it again.
Why it works
How the lessons teach
Courses follow CEFR levels and Task-Based Language Teaching: you practice the email, standup, or pitch you have this week, then get the grammar that holds it up.
The explicit pedagogy rule
"You should say 'must complete,' not 'must to complete.'"
Explicit pedagogy
No correction without the rule.
Alex names the grammar rule, the vocabulary issue, or the cultural mismatch, then gives you the corrected sentence.
Spaced repetition
Return to the language after the first lesson.
Vocabulary returns in later practice instead of ending with a single quiz. Use the rehearsal brief to bring the language back into work you are doing now.
Formative-first assessment
Continuous, low-stakes, timely.
Fill-ins, email rewrites, and role-play evaluations run throughout each lesson - not just at the end. Feedback is specific, timely, and tied to your CEFR target.
Authentic material
Stripe, Google, Salesforce, YC.
No "Mr. Smith writes to Mr. Jones" drills. Every lesson is grounded in real companies, real industry events, and real communication patterns from global tech hubs.

The sessions are available online. A Bogotá meeting may be arranged when it fits the situation and both parties confirm the location in advance.
