We support global business development with our own global sales team – identify the target market and get the first deal.
We assist with the creation of a legal framework for licensing businesses – from the NDA to the licensing agreement.
We coach Diamonds during their scale-up phase in various areas, such as marketing, strategic teaming and executive coaching.

We accelerate startups by transforming ideas, leading growth, mentoring, and educating talents & teams.
Our Global Acceleration Program (GAP) encompasses all mission-critical elements to develop an idea into a solid investment proposal. Among others, this includes product definition, storytelling, brand-building, sales development, legal matters, and talent management.

Tell Your Story & Build Your Brand

Developing a clear marketing and brand strategy is as essential as the financial forecasts and product roadmaps and provides clarity, context and a powerful message.
By using basic building blocks such as a company mission, vision, and positioning statement and combining it with a strong company story, clarity and context are provided and a powerful message is created.

Complete Your Team

A compact analysis helps founders understand the management approaches from the organizational- and the people-perspective to find the right team members with the necessary skills and experiences. The focus lies on the individual implementation of organizational learning to steer sustainable growth, harvest success, retain key people, and attract new talents.

Close Successful Deals

Licensing agreements represent the bedrock of a successful startup but fail to realize their potential without the right structure and scheme in place.
Silicon Castles helps startups in deploying an international licensing scheme that is in accordance with accepted licensing practices and a strong negotiation strategy. This allows startups to fine-tune their engine, gather momentum, and secure successive deals.

A network including major technology players can be the key to successful sales for startups. Silicon Castles offers access to its global network in the US and Asian markets and immediately introduces its startups to relevant partners and customers. We support startups in building a skilled sales team to land the first big deal, which is crucial to find investors.

Startup Executive Academy

The Startup Executive Academy (SEA), founded in 2017, is an international Go-to-Market program for early-stage (seed, A or B phase) technology startup executives and founders. The program aims to enable startups to accelerate their business by providing highly relevant and practical input. The program is delivered by a world-class faculty from academia and business and led by Prof. Baba Shiv from the Stanford Graduate School of Business.

The SEA is run as a hybrid program incorporating aspects of both a face-to-face and an online program. 

Learn more

The highly practical, hands-on Go-to-Market sessions cover topics such as business model & strategy, value proposition, story telling, pricing, negotiation, sales and investment. Alongside the sessions, the participants work on their startup’s challenges by completing e.g. the BMC, the Sales Canvas and the Investment Memorandum Canvas.


The program is led by Prof. Baba Shiv from the Stanford Graduate School of Business. The faculty includes executives and former leaders of global companies like Dolby, Sony, PWC, McKinsey, Napster, and Deutsche Telekom. Participants have the opportunity to meet experts from different fields in 1:1 meetings to discuss the current challenges of their startups.


During the lectures, the 1:1 sessions with faculty members and the regular exchanges with their peers, the participants develop ideas, gather knowledge, and collect feedback. They can immediately use this input to accelerate their business and take their company to the next level.


The SEA CIRCLE is the alumni network of former SEA participants and enables continuous learning through regular SEA CIRCLE Sessions. In these sessions, participants get input from the SEA faculty on currently important startup topics, they can share their experiences on success and failure and receive advice from peers.
