About the program

Startup Wise Guys accelerator is a no BS, hands-on 3 month intense mentoring program with focus on idea shaping and validation, business development, sales and fundraising, topped up with a Tech Week for CTOs and developers, as well as exposure to investors during regional Tech events and special match-making opportunities.

Or put in another way – it is almost like a sports camp for startup founders – accelerator teaches discipline and creates positive competition speeding-up progress and enhancing learning from other startups from the batch. And did we mention the fun side of it with tequila nights, getaway deep in the countryside with sauna and hot-tubs, and graduation party with dances till 5am?

Accelerator Timeline

Accelerator program consists of 3-months intensive mentoring focused on idea shaping and validation, business development, sales and fundraising. But don’t worry – our Geek Squad will keep your developers challenged and busy too!

Applications Open

Startups can apply online and catch the accelerator team for a chat, office hours and free mentoring on our roadshow. Follow our Facebook page for updates on upcoming events.

Selection Bootcamp - September

Our selection committee, consisting of investors, mentors, corporates and Startup Wise Guys team, will select up to 25 startups who will be invited for the Selection Bootcamp event in Tallinn, Estonia, in September.
Program Starts

October - November

Teams relocate to Tallinn in October and start working at the co-working space. During the first month of accelerator program, startups go through intensive speed mentoring, as well as dive into hands-on workshops on business model, product-market fit, experiment design and of course sales.


Once the business model and sales strategies are in order, startups go deeper in specific topics during Tech, Marketing and Investor weeks.
Christmas Break


Teams get broad exposure to Business Angels and VCs, with several opportunities to pitch at high profile regional startup events including Startup Day (Jan 23-25) and TechChill (Feb 21-22).


Mentoring intensity trails off in the last month of the program to allow teams to finally “do the real work”. The program officially finishes in February.

After-care: February - May

Accelerating in Estonia

Estonia – the home country of Skype and recent unicorns Transferwise and Taxify – is also the birth place of Startup Wise Guys accelerator. In 2012 a group of successful entrepreneurs and startup founders (some related to notorious Estonian Mafia) created a support platform for young entrepreneurs to help them grow. After 2 consequent batches in Riga, Latvia, Startup Wise Guys team is coming home and 12th program with B2B SaaS focus is going to be held in Tallinn.
With only 1.3 million inhabitants, Estonia has become a global phenomenon. In the first half of 2018 alone, Estonian startups have raised above 240 million euros (and counting). Accelerating in Tallinn, you are working side-by-side with existing and upcoming unicorns and also getting access to one of the most active Business Angel communities in the region – the EstBAN – that have just invested a syndicate of 170K in one of our recent alumni Fractory.
But apart from the shiny numbers and success of local startups, there’s a convenient system in place to welcome foreign founders – a special Startup Visa (startups selected to accelerator get fast-track), as well as E-residency program. You can establish a company online in 15 minutes and do your taxes in 3 minutes. All of that is possible in English and from anywhere, as long as you have internet access.

Join the #EstonianMafia and grow in a tight ecosystem of successful tech founders!
