How to Prepare for Slush 2026: A Founder's 3-Week Checklist

If you are wondering how to prepare for Slush, the honest answer is: start now, and spend less time on the deck than you think. Slush 2026 takes place in Helsinki on November 18 and 19, with Day 0 for founders the day before. That leaves roughly three weeks. It is enough time to arrive with a plan, a full calendar and a pitch you can say without thinking. It is not enough time if you wait until the flight.

Most founders who come home from a startup event disappointed did not have a bad product. They had a vague goal, a half-empty schedule, and a pitch that sounded different every time they said it. The conversation is where things go wrong, so that is where most of your preparation should go.

Julia Georgi (Startup Witch, KB&G) learned the other half of this at Slush 2025, where she went with Georgia. "I prepared, I filtered, I scheduled, I strategized and still got hit with surprises that no prep guide ever mentions." Meetings were cancelled at the last minute. People who had accepted did not show up. The meeting platform went down for almost a full day. So this checklist includes a plan B, because at an event this size something will go differently than you planned.

This checklist breaks the three weeks into concrete tasks. It is written for Slush, but the same countdown works for any big startup event where founders, investors and operators meet in one place.

Before you start the checklist, watch Julia Georgi's honest review of Slush 2025: what went wrong, what worked anyway and what she would do differently. It is on Startup Witch on YouTube.

Why Preparation Matters at Slush

The Slush FAQ puts the 2026 event at 5,800 startups and 3,300 investors, and most meetings are booked through the Slush Meeting Tool before the event starts. That means the weeks before Helsinki decide most of what happens there. Every founder in the building is competing for the same attention, and the ones who get it are the ones who can explain their company clearly in the first minute.

The trap is spending two days walking, watching talks and collecting business cards that turn into nothing. A busy week feels productive. Whether it was depends on the conversations.

Preparation turns that access into outcomes. A founder who knows exactly who they want to meet, has requested those meetings early, and can explain the company clearly in thirty seconds will get more from one day than an unprepared team gets from the whole week. The effort you put in before the doors open is what you get back after Slush.

Slush Week Runs on the Market Clock

Julia Georgi (Startup Witch, KB&G) describes two clocks every founder lives by. Your build clock moves every day: a new feature, a fixed bug, a cleaner deck. Your market clock moves only when someone outside your company changes their behaviour. A buyer agrees to a pilot. An investor asks for the data room. Everything else is preparation.

The trap is that building pays out instantly, while market work pays out late and mostly in silence. So anyone rational drifts toward building. As she puts it, this says nothing about your character. It is simply how the incentives are wired. Many founders know the feeling: "I said I'd start selling this month. I've been saying that since March."

Slush is two days where the market clock can move fast, because the people who can change their behaviour for you are in one building. Startup Witch's rule of thumb fits the week well: ten honest conversations tell you more than another month of building. Prepare for Slush as a week of conversations, and measure success by what other people agreed to do afterwards.

A quick self-check before you plan anything: look at your last ten conversations with customers or investors. How many started with your product, and how many started with their problem? If most started with your product, that is the habit to fix in rehearsal over the next three weeks.

Three Weeks Out: Set Goals and Build Your Target List

Pick two or three outcomes

Before you touch the Slush platform, write down what a good Slush looks like for your startup. Be specific. "Network" is not a goal. These are:

• Have 8 first meetings with seed investors who invest in our sector.
• Book 3 follow-up demos with potential customers in the Nordics.
• Meet 2 potential partners for our pilot in Germany.
• Talk to tech journalists covering our space and leave with one follow-up conversation.

Two or three outcomes is the right number. If you are a co-founder team, split them. One person owns investors, the other owns customers and partners. This also stops two founders from pitching the same person twice.

Add a plan B

Julia's biggest planning mistake at Slush 2025 was a goal she never set. "I didn't think at all about finding pilot customers. Zero preparation, zero strategy." She was so focused on investor meetings that she only noticed the gap on site, then sent last-minute meeting requests and still met several prospects who were a very strong match. Her lesson: "You need a clear goal and you must stay flexible." Write down a backup goal now, and the type of person you would look for if your main meetings fall through.

Build the target list

Now list the people who can help you reach those outcomes. For each goal, find 15 to 30 names: venture funds and angel investors who back your stage and sector, the CEO or head of operations at customers who fit your ideal profile, partners, and tech journalists or other media contacts. A simple table is enough.

Name	Type	Why them	Status
Fund or person	Investor / customer / partner / media	One line on fit	Requested / accepted / met / follow-up sent

Prioritise. Mark your top ten. Those get personalised requests first, and those are the people you will look for at side events if the Meeting Tool does not work out.

Register for Day 0

Day 0 for Founders on November 17 has limited capacity and needs a separate registration on the Slush Platform. If you go, treat it as rehearsal: a day of lower-stakes conversations where you can test your intro before the main event.

Two Weeks Out: Use the Slush Meeting Tool

The Meeting Tool is how you book one-to-one meetings with investors, customers and other participants in the Meeting Area. According to the Slush FAQ, most meetings are booked right after the tool opens, and each meeting lasts 25 minutes. Send your requests as soon as you can.

Complete your Slush platform profile first

Your profile is the first thing interested investors, customers and other participants see before they accept or decline. Create a profile that makes it easy to say yes:

• One sentence on what you do, for whom. No jargon.
• Stage, sector, location and what you are looking for (round size, pilots, partners).
• One proof point you can stand behind: paying customers, a pilot, a waitlist, a technical milestone.

Search by keyword when the categories do not fit you

The Meeting Tool's category and stage filters are broad. At Slush 2025, the closest category for Georgia, a role-play platform for soft-skills training, was health and well-being. Investors told Julia her "well-being app" was irrelevant to them. The fix was a keyword search. She typed "human" into the search, and investors who back human development, learning, talent and people operations appeared even though their category tags did not match.

Check stage fit by hand as well. One investor accepted a meeting with Julia, then lost interest when she said Georgia did not yet have one million in revenue. Build your target list outside the tool, in a spreadsheet or CRM, and review each name yourself. Julia exported her prospects to a CRM, which made planning much simpler.

Write meeting requests that get accepted

Investors and busy operators get many requests. Generic ones get ignored. Personalised outreach sent early has a far better chance than a copy-paste note sent the week of the event. A good request is short, specific and shows why the meeting has value for them as well as for you.

Keep it under 300 characters. That is the length limit for a Meeting Tool message, and Julia is honest about it: "Maybe that's why I was ghosted. I wasn't good at this." Write your request, count the characters and say it out loud. If it does not sound like something you would say to a person, rewrite it.

Template for investors:

"Hi [Name], we're building [one-line description] for [customer]. We're raising a [stage] round and have [proof point]. I saw you invested in [relevant company] and think our approach to [problem] fits your thesis. Would you have 20 minutes at Slush to talk?"

Template for customers:

"Hi [Name], we help [role] at companies like yours [outcome]. Teams like [anonymised example] use us to [result]. I'd value 20 minutes at Slush to hear how you handle [problem] today. I'll leave the pitch deck at home."

Keep your digital profile and pitching materials updated as things change. If you sign a customer on November 5, add it before the event.

Track every request in your table. Follow up once if there is no answer after a few days. Then move on.

Prepare for Mentoring and Investor Office Hours

Treat Mentoring and Investor Office Hours as real meetings. Decide what you want to learn, prepare one or two precise questions ("Would you lead with the enterprise or the SMB use case in this pitch?"), and bring a short version of your story.

Choose side events by goal

Slush Week has many side events around the city, from small dinners with a few seats to large parties where hundreds of people participate. Many are run by funds, startups and community groups who host for a specific audience. Pick them the same way you picked your targets: does this event put me in a room with people on my list? Two or three well-chosen side events per day beat eight you rush through, and the ones you skip will not matter by Friday. Put them in your calendar with the venue, travel time and who you hope to meet.

Pitch Practice: Rehearse the Conversation Out Loud

This is the part most founders skip. They polish slides, then improvise the words. At Slush, most of your conversations will happen without a screen: in the Meeting Area, in a queue, at a side event, over coffee. What you say out loud is the pitch.

Prepare three lengths

• The 30-second intro. Who you are, what you build, for whom, and one proof point. You will say this dozens of times. Try: "I'm [Name], co-founder of [company]. We help small logistics firms cut failed deliveries with route-level predictions. We're live with six customers in Finland and raising our seed round."
• The 2-minute pitch. Problem, solution, why now, traction, team, and the ask. This is for a short meeting or an investor who says "tell me more".
• The 25-minute meeting. That is the length of a Meeting Area slot. Treat it as a conversation. Pitch for five minutes, let them ask, and keep the last five minutes for the next step. Know which slides you would show if they want detail.

Prepare for the questions you dread

Every founder has them. "Why won't a big player just build this?" "What's your burn?" "Why you?" "What happens if your main customer leaves?" Write down the five you least want to hear. Draft a short, honest answer to each. Then practise saying them out loud until you can answer calmly. The question you didn't prepare for is the one that sticks in the investor's memory.

Practise out loud, under pressure

Reading your notes in your head is not practice. Effective pitch practice means:

1. Say the pitch out loud, standing up, every day for the next two weeks.
2. Record yourself on your phone. Listen for filler words, rushed numbers and the moment your energy drops.
3. Practise with someone who interrupts and asks hard questions. A co-founder, an advisor, a friend who will not be polite.
4. Practise the transitions: how you move from small talk to your intro, and from the meeting to the next step.

If you can't find a willing sparring partner every day, an AI role-play partner works well here. With Georgia you can rehearse an investor meeting or a customer conversation by voice, get pushed with follow-up questions and receive feedback on how you came across. Rehearse your Slush pitch with Georgia before you are standing in the Meeting Area.

One Week Out: Schedule and Materials

Lock the schedule

Put every confirmed meeting, office hour and side event in one calendar shared with your co-founder. For each meeting, add one line on who the person is and what you want from the conversation. Then consider booking back to back. Julia usually recommends buffers, but at Slush the Meeting Area is compact, and her experience was that "your chance of meeting the right person is higher when you have a full schedule" than when you plan it safe. Expect some cancellations and no-shows to open gaps for you anyway.

A realistic day looks like this:

Time	Block
Morning	2 to 4 booked meetings in the Meeting Area
Midday	Free time: walk the venue, one talk, lunch, unplanned conversations
Afternoon	2 to 4 booked meetings or office hours
Evening	One or two side events, then 20 minutes of notes and follow-ups

Prepare materials

• A deck you can show on a phone or laptop in a noisy space. Big text, few words.
• A short send-ahead version as a PDF, ready to share after a meeting.
• A one-page summary or landing page you can point people to. Keep your assets in one shared folder.
• A product demo that works offline. Venue Wi-Fi at a big event is not something to bet on.
• A phone charger and a power bank.

At the Main Event: Make Every Conversation Count

Treat each investor day like a sales day

When you arrive, your job is simple: show up to every meeting on time, keep conversations focused, and agree on a next step before you leave each one.

At the end of every meeting, ask for something specific: "Could I send you our data room next week?" "Would a demo with your ops lead make sense?" "Who else on your team should I talk to?" If you cannot agree on a next step, that is useful information too.

Work the unplanned conversations

Unplanned conversations matter as much as booked ones. When you find yourself next to someone interesting in a queue or a small group at a side event, use your 30-second intro, then ask a question about them. Most founders talk too much and listen too little. A good question earns you the right to pitch.

That was Julia's biggest surprise at Slush 2025. She came mainly for booked meetings, and the founders, early employees from top startups and product owners from big tech she met outside them turned out to be as valuable as most of her scheduled conversations. If you can, bring a co-founder or teammate whose job is to network and capture leads. Going alone was her biggest regret: "A good wingman doubles your reach."

Take notes right after every conversation, even if it slows you down a bit. Name, company, what they care about, the next step, and one personal detail. You think you will remember. After 15 meetings in two days, you will not. Save your notes in one place, so your co-founder can see who you met and what you accomplished.

After Slush: The Follow-Up Plan

The follow-up is where most of the value of a startup event is won or lost. It is also the email nobody sends. Plan it now so that it happens.

• Write templates for investors, customers and partners before you leave. Personalise one line in each.
• Send follow-ups within 48 hours, while you are still fresh in their memory.
• Block time in your calendar for the Monday and Tuesday after Slush. No other work.
• Move every contact into your CRM or tracking sheet with a status and next step.

A simple follow-up: "Great to meet you at Slush, [Name]. As promised, here is [deck / demo link / intro]. You mentioned [specific thing they said]. Would [date] work for a 30-minute call?"

Following up is also a conversation skill. If calls after Slush feel harder than the meetings themselves, practise them too. Practise your follow-up calls with Georgia so the second conversation is as strong as the first. You can read more in AI Sales Role-Play: Rehearse High-Stakes Conversations Before the Call.

Frequently Asked Questions

How do I prepare for investor meetings at Slush?

Research which investors fit your stage and sector, request meetings early in the Meeting Tool and plan each 25-minute meeting with a clear ask. Then rehearse the hard questions out loud, with a co-founder or an AI role-play such as Georgia that plays a sceptical investor and gives you feedback.

Where and when is Slush 2026?

Slush 2026 takes place in Helsinki on November 18 and 19, 2026. Day 0 for founders is the day before the main event. See slush.org for details.

How do I practice my pitch?

Say it out loud every day, standing up. Record yourself and listen back. Practise with someone who interrupts and asks the questions you fear. Prepare a 30-second, a 2-minute and a 20-minute version, so you are ready for every type of conversation.

How can I practice pitching at home?

Use your phone to record and time yourself, write down the five hardest questions and answer them aloud, and use an AI role-play tool to simulate an investor or customer who pushes back. Short daily sessions work better than one long rehearsal the night before.
