Startup Wise Guys
How to get into Startup Wise Guys according to the founders who pulled it off
Our take
Best if you are an early-stage B2B SaaS founder who wants Startup Wise Guys' intense, hands-on mentorship and a European network to go global. A weak trade if you already have traction and a network and only want capital, or won't give up equity for a small check the program fee comes out of.

We asked the founders how Startup Wise Guys really went.
Every interview behind this page is one we ran ourselves. The numbers and quotes come straight from founders who went through Startup Wise Guys, in their own words.
Who Startup Wise Guys is for, and who should skip it.
Best for
- You are an early-stage B2B SaaS founder and want sector-specific mentorship from people who have built in your space
- You are based in an emerging or overlooked market and need a European investor network to go global
- You want hands-on coaching on sales, pitching, and fundraising more than you need a big check
- You are coachable and ready to have every assumption about your product challenged
Skip it if
- You already have real traction and a strong network and only need capital
- You do not want to give up equity, or accept a program fee coming out of the check
- You cannot give the program serious hours on top of running your company
- You want a hands-off accelerator that leaves your product and strategy alone
What it's actually like at Startup Wise Guys
Startup Wise Guys runs in themed batches, a fintech cohort, a cybersecurity cohort, a sustainability or XR cohort, each one a group of roughly ten startups moving through the program together. The pace is the first thing founders mention. A typical week gives about two days to workshops, mentor sessions, and homework, all of it on top of actually running your company, and the founders who went through it were honest that the juggling was the hard part.
Most of the calendar is mentorship. Twenty to thirty mentors cycle through each batch, often one or two a day, working through the parts of a business that early founders tend to neglect, sales, fundraising, legal, market sizing, and the pitch. It has the feel of a degree compressed into a few months.
It felt like going back to university, only more useful. There was homework too.
Pitching is the spine of the program. You pitch early, you pitch often, and the feedback is direct enough to sting, which is the point. Founders describe walking in with a cluttered deck and a fuzzy story and walking out able to land the business in a sentence. Expect every assumption about your product to get questioned along the way, and expect some teams to pivot hard because of it.
We used to joke it was like an MBA on steroids, a fair comparison given Wise Guys is now housed at the Estonian Business School, where we'd studied.
What founders keep coming back to is the people. The mentors stay reachable after the program, the alumni network across Europe and emerging markets stays active, and Startup Wise Guys keeps showing up long after demo day. More than one founder described their investors as part of the team.
They reply to our monthly reports, stay engaged, and behave like part of the team.
What the check is really worth
The headline ticket is small by accelerator standards. Startup Wise Guys has historically invested around €50,000 to €55,000, and the figure now runs up to €100,000 depending on the batch and the company's stage. In most cases it arrives as a convertible note rather than immediate equity, which defers the valuation conversation to your next round.
The number that matters is what actually reaches your bank account, because the program fee comes out of the headline first.
We received a total of 55,000 euros through Startup Wise Guys, structured as a convertible note with a valuation cap. 25,000 euros covered program fees, so 30,000 euros actually landed in our bank account.
Equity is negotiated rather than fixed, and it tracks the stage you join at. Founders reported giving up single digits, with the note converting later instead of locking in a valuation upfront.
On acceptance, you receive around €50,000 from Startup Wise Guys. Half covers program costs and €25,000 is yours for early activities. It's a prelude to the seed round, and in exchange you give up three to six percent of the company.
There is upside built into the deal. Many founders took a follow-on once they had proven something, often around €100,000 to €150,000 more, which can push Startup Wise Guys' total investment past €200,000. What founders valued most, though, was rarely the money. They pointed to the sharper pitch, the credibility of the name on their cap table, and the investor introductions the check opened up.
How founders actually got in
The formal path is an online application, then one or two pitch rounds where you present to a group and field questions, then a deeper round of meetings with the heads of different departments. The final stage is a pitch to the investor community, and in some batches a two-day Selection Bootcamp where the shortlisted teams demo and defend the business in front of mentors and investors. Founders with real traction said they were able to skip some of the earlier stages.
Plenty of founders never applied cold at all. Startup Wise Guys scouts actively, and several were approached on LinkedIn or at events before they ever filled in a form. However you get there, it is competitive. Founders described batches that took eight to ten startups from twenty to thirty finalists, with hundreds of applications further up the funnel, and the overall rate sitting around 3%.
The founders who pulled it off gave the same advice.
Don't apply with a soft pitch. The program will refine it, but you can't show up with a half-formed idea and expect them to build it for you. You need to know your business cold.
What actually moves the needle, in the founders' own words.
- Know your numbers cold, traction, conversion, churn, the kind of detail that comes up early if you are a SaaS company
- Be transparent about your vision, your figures, and where you might still pivot, honesty landed better than a polished story
- Prepare for the hard questions, especially why you want an accelerator at all and why this one
- Lead with traction and a clear plan to expand globally, it is what stands out in a crowded batch
- Rehearse the pitch out loud until it is clear in seconds, the selection days are back-to-back pitching

Questions founders ask about Startup Wise Guys.
Around 3% of applicants get in overall, though it varies by batch. Founders described eight to ten startups chosen from twenty to thirty finalists, with hundreds applying further up the funnel. Selection runs across an online form, one or two pitch rounds, and deeper interviews with department heads.
Single digits, negotiated rather than fixed. The investment is usually structured as a convertible note, and founders reported giving up roughly three to eight percent depending on the stage they joined at. The note converts to equity at a later round instead of locking in a valuation upfront.
It runs as a themed batch, fintech, cybersecurity, SaaS, sustainability or XR, with around ten startups going through together over several months. The days are dense with workshops, daily pitching, and one-to-one time with twenty to thirty mentors, all on top of running your company. Most of the work is sharpening sales, the pitch, and a fundraising-ready story.
The core program runs about five months, though it ranges from three to six depending on the batch. Founders described an intense front stretch of full-time workshops, then a shift into applying what they learned and preparing for the next funding round. The mentorship and alumni network keep going long after the program ends.
It depends on where you start. Founders who were early-stage B2B SaaS, especially those from emerging markets who needed a European network, said the mentorship, the pitch coaching, and the credibility were worth the equity. If you already have traction and a strong network and just want capital, a small check with a program fee taken out is a weaker trade.
