SILICON VALLEY ACCELERATOR
Prague → San Francisco → Global Growth
A program that transforms founders’ mindsets, sharpens strategies, and connects CEE startups with the right people in Silicon Valley.
This is not for everyone. And that's exactly why we do it.
Silicon Valley Accelerator is an exclusive accelerator for CEE startups that have already achieved traction at home—and now want to go global. But not with a “let’s try and see” approach. We want founders who understand that growth isn't a buzzword—it’s hard work and real pressure.
WHAT STARTUPS CAN EXPECT
GO GLOBAL
The Silicon Valley Accelerator is a three-phase program designed for ambitious startups from Central and Eastern Europe. Its goal is to prepare founders to enter international markets—not just in mindset, but also strategy, product, sales channels, and investor communication.
INTENSIVE TRAINING
The program combines deep preparation in the Czech Republic with a two-week acceleration in San Francisco. It’s based on real-world experience from founders, investors, and experts from both the U.S. and European startup ecosystems. No lectures—only practice.
MADE BY US
We run the program in cooperation with US MAC (U.S. Market Access Center)—an experienced acceleration platform for entering the U.S. market. We bring in our own scale-up and investment scene know-how. And it works.
HOW IT WORKS?
The program runs every year in three parts:
Team Selection
We select startups between February and May. Entry is by direct nomination only. Criteria: validated product, paying customers, at least 6 months runway, a committed team, and good English.Bootcamp in Prague
A three-day training in Prague to set strategy and prepare teams for the U.S. phase. We cover product, sales, storytelling, fundraising, and metrics—plus one-on-one mentoring.Acceleration in Silicon Valley
Two weeks in San Francisco featuring mentoring with local industry experts, B2B meetings with potential clients to identify their needs, investor pitch sessions, workshops on scaling, finance, legal matters, networking with local founders, and final sessions on next steps.Afterward, there's individual follow-up and continued mentoring post-return.
WHY WE DO IT
There is an abundance of talented founders in the CEE region. But what’s often missing is experience growing outside their home market, direct access to international customers, and credibility with foreign investors.
The Silicon Valley Accelerator was created to address this. We connect CEE talent with Silicon Valley know-how and networks—so companies don’t remain dependent on their local environment but can compete globally. It’s not just about “expansion”; it’s about building the ability to scale, adapt, and succeed across different market contexts.
WHAT WE'VE ACHIEVED
In the past two years, the program has onboarded 28 startups from 6 countries. We've facilitated over 100 meetings with U.S. customers and investors, delivered over 220 hours of mentoring, and conducted dozens of hands-on workshops.
Alumni include startups such as Blockmate, SmartHead, Investown, Tuito, and Wflow. Their next steps show that a program focused on quality over quantity truly makes sense.
