Hackathon Playbook Ch.04: Timeline & Milestones

Realistic planning timeline from 4-6 months before through post-event. Phase-by-phase breakdown, fast-track 6-week compressed timeline, and event duration guidance.

Written by Nate Rundberg

Chapter 4: Timeline & Milestones

When to start planning (hint: earlier than you think)

The single biggest mistake first-time organisers make is underestimating how long things take. Booking a venue takes weeks. Sponsor outreach takes months. Building an audience takes time. And somehow the event date arrives faster than seems physically possible.

This chapter gives you a realistic planning timeline. Use it as your roadmap — adapt the details, but respect the lead times.

The ideal timeline: 4–6 months before

Yes, really. If your event is in September, you should be making key decisions in March or April. Here's why: venues need to be booked, sponsors need lead time to approve budgets internally, and you need time to build an audience.

If you have less time, you can compress — but know what you're trading off (see "Fast-track: 6 weeks" below).

Phase-by-phase breakdown

4–6 months before: Foundation

This is where the big decisions happen — the ones from Chapters 1–3.

  • Define your objective and SMART goals (Chapter 1)

  • Choose your format: on-site, online, or hybrid (Chapter 2)

  • Nail down your business model and rough budget (Chapter 3)

  • Set the date and duration (24hrs, 48hrs, one week, etc.)

  • Check for calendar conflicts — holidays, competing events, university exam periods

  • For on-site/hybrid: start venue research and booking

  • Define your target audience and expected participant count

  • Assemble your core organising team and assign roles

  • Set up team communication (Slack channel, shared docs, weekly meetings)

Key role assignments at this stage:

  • Event Director (overall owner)

  • Operations Lead (logistics)

  • Marketing Lead (promotion, comms)

  • Sponsorship Lead (funding)

  • Technical Lead (platform, tools, APIs)

  • Community Manager (participant engagement)

Not every event needs all these roles, and on a small team one person might wear multiple hats. But someone needs to own each area, even if "someone" is you doing three jobs.

2–3 months before: Build

Now you're executing against the foundation you set.

  • Launch sponsorship outreach — this takes time, start early (Chapter 5)

  • Finalise budget based on confirmed sponsors + projected registration (Chapter 6)

  • For on-site: confirm venue, start logistics planning (Chapter 7)

  • For online: finalise your platform stack (Chapter 7)

  • Set up your event on BuilderBase — event page, registration, challenges (Chapter 8)

  • Develop your theme and specific challenges/tracks (Chapter 9)

  • Begin recruiting judges and mentors (Chapter 11)

  • Launch marketing — website, social media, email lists (Chapter 12)

  • Open registration

  • Draft your Code of Conduct

  • Start community building (Slack/Discord workspace, pre-event content)

1–2 months before: Promote & prepare

The event is taking shape. Now it's about filling seats and preparing content.

  • Push marketing hard — you need registrations flowing in

  • Continue sponsor outreach and onboarding

  • Confirm judges, mentors, speakers — collect bios, photos, availability

  • Prepare workshop content (if offering workshops)

  • Configure judging rubrics and submission requirements on BuilderBase

  • Prepare API documentation, datasets, starter kits (if relevant)

  • Prepare opening and closing ceremony content

  • Set up Slack/Discord with proper channels and welcome messages

  • Invite registrants to community channels

  • Begin team formation activities (pre-event mixers, idea brainstorming)

  • Plan food and catering (on-site events)

2 weeks before: Final prep

Crunch time. Everything should be converging.

  • Close any remaining sponsor deals

  • Finalise participant list and manage waitlist

  • For on-site: do a venue walkthrough — test wifi, power, projector, microphone, bathrooms

  • For online: test all platforms — video conferencing, HackOS, submission portal

  • For hybrid: test the full AV bridge — cameras, livestream, two-way audio

  • Send "10 days before" email to all registrants (schedule, logistics, what to prepare)

  • Brief your judges — share rubric, process, expectations

  • Brief your mentors — share challenge context, availability expectations

  • Recruit and brief volunteers

  • Finalise opening/closing ceremony scripts

  • Prepare signage, handouts, wifi cards (on-site)

  • Prepare documentation plan — who's taking photos, managing social media?

3 days before: Lock it down

  • Send detailed logistics email (schedule, access info, final reminders)

  • Set up group communication channels if not done yet

  • Place catering orders (on-site)

  • Print participant list for security/check-in

  • Charge all devices — cameras, laptops, phones

  • Prepare emergency contact list

  • Prepare supplies kit (power strips, markers, tape, name badges, adapters)

1 day before: Final check

  • On-site: full venue walkthrough — tables, chairs, power, wifi, AV, bathrooms all working

  • Online: test all links one more time — video call, platform, submission portal

  • Send "see you tomorrow!" email with start time, access link/location, what to expect

  • Slide deck ready, scripts ready, backup plans ready

  • Get some sleep. Seriously.

Event day: Execute

See Chapters 13–16 for the full execution playbook.

48 hours after: Follow-up

  • Send thank-you emails to everyone (participants, sponsors, judges, mentors, volunteers)

  • Share photos, winner announcements, survey link

  • Post social media highlights

  • Begin sponsor reporting

1 week after: Close out

  • Collect and analyse survey responses

  • Hold team retrospective

  • Finalise financial reconciliation

  • Complete sponsor reports and deliverables

  • Write post-mortem and publish learnings

Fast-track: 6-week timeline

Don't have 4–6 months? Here's a compressed version. It's doable, but you're trading depth for speed.

Weeks 1–2: Foundation decisions (objective, format, budget) + venue/platform booking + begin sponsor outreach + set up BuilderBase event page + open registration

Weeks 3–4: Launch marketing hard + confirm judges and mentors + develop challenges + configure submission and judging on BuilderBase + build community channels

Weeks 5–6: Final logistics + participant comms (10 day, 3 day, 1 day emails) + venue/platform testing + briefings for judges, mentors, volunteers + event execution + follow-up

What you lose in a compressed timeline: big-ticket sponsors (they need internal approval time), a large registrant pool (marketing needs time to work), polished content and materials. What you keep: a real event that people will remember.

Duration: how long should the event be?

This is a separate question from the planning timeline. How long is the event itself?

  • 4–8 hours (half-day or evening): Low commitment, great for newcomers, limited scope but focused output. Works well for workshops or themed build sessions.

  • 24 hours: The classic hackathon format. Enough time for real projects but short enough to maintain energy. One overnight push (though we recommend people actually sleep).

  • 48 hours (full weekend): The most common format. Friday evening kickoff → Sunday afternoon demos. Allows for deeper work, but energy management becomes critical.

  • 1 week (distributed): Usually online, with participants working in their own time. Lower intensity but allows for more thoughtful work. Requires strong async communication.

Match duration to your objective. Community building? A half-day jam might be perfect. Product prototyping? You probably need 48 hours. Training? A full day with workshops.


Key takeaways:

  • Start planning 4–6 months ahead for an ideal timeline; 6 weeks is the compressed minimum

  • The first decisions (objective, format, budget, date) unlock everything else

  • Sponsor outreach needs to start 2–3 months out — companies have slow approval cycles

  • Never skip the venue/platform walkthrough 1–2 days before the event

  • Post-event follow-up within 48 hours while energy is fresh

  • Match event duration to your objective — longer isn't always better

  • Someone needs to own each planning area, even if your team is small
