Founders meet investors. One round at a time.

Cohort communities, mentor office hours, founder–investor video rounds and your curriculum, on one platform that carries your accelerator's name, not ours.

Today

Your program runs on six tools. None of them talk.

Founders get a different link, login and logo for every part of the program. You get six exports and no single view of who is engaged.

  • Live sessionsZoom · Google MeetNo brand on the call, recordings in someone's drive, no attendee data you own.
  • Cohort communityWhatsApp · CircleNo cohort separation. The best conversations scroll away by week three.
  • Mentor office hoursCalendly · emailA link, not a program. You can't see who booked whom, or who never showed.
  • Demo-day matchingA spreadsheetBuilt by hand the night before, and it breaks once you pass twenty founders.
  • CurriculumMoodle · TeachableAnother login, disconnected from the sessions and the community.
  • AlumniA group chatGoes quiet the week after demo day.

Your team ends up running logistics while the program waits.

Your brand

A white-label accelerator platform: your name on every screen.

What changes

Three things your program is judged on.

Outcome 01 · Mentors
Every founder meets the right mentors without me scheduling it.

Mentors publish office hours with their own availability. Founders book a slot, and when the mentor accepts, the video call is created for both of them. Keep it free, or let senior mentors charge.

  1. A booking page per mentorTitle, duration and price, public or visible only to your founders.
  2. Accept creates the callNo Calendly, no meeting links, no email threads.
  3. Every booking in one listYou can see who met whom, and when.
founders.lumenfounders.com/consultations
Outcome 02 · Alumni
Alumni stay in our network after demo day.

One private community per cohort, and an alumni community that grows with every batch. Add everyone from demo day in one go, and keep them meeting in rooms, channels and events.

Outcome 03 · Partners
Show LPs and partners real engagement.

Course progress for every founder, attendance at every session and a summary of the connections made in each round. Export it to CSV or Excel for the next partner update.

Course analytics: 48 members, 31 started, 21 completed, and each member's lesson completion with last activity
Cohort week one

Founders meet founders.

Choose Same and every round pairs two founders from the cohort. In one session, founders meet a new peer every few minutes, before the program asks them to share hires, customers and lessons.

  1. A new founder every roundNobody meets the same founder twice, so a cohort gets to know each other in one session instead of a month.
  2. A question to startEach round opens with an icebreaker on screen, and either founder can ask for another.
  3. A list of who they metFounders keep every connection and follow up in the cohort community.

Demo day

Founders on one side. Investors on the other.

Name two roles and choose Opposite. Every round pairs a founder with an investor, face to face on video, and nobody meets the same person twice.

  1. Two roles, Same or OppositeFounder and Investor for demo day. Switch to Same for founder-to-founder rounds in week one.
  2. You set the clockRounds run from 3 to 15 minutes. The form shows how many conversations fit before you publish.
  3. Intro and outro roomsOpen with your welcome, close with the whole room together.
  4. A summary of every connectionFounders keep a list of who they met. You keep the count.

Example: a 90-minute room with a 10-minute intro and 7-minute rounds fits up to 11 rounds. The form does this sum for you.

Rollout

Live for your next cohort. Set up with you.

You don't get a login and a help centre. Our team configures the platform with you, working back from your cohort calendar.

  1. Scope

    One call about your cohort calendar, your roles and what demo day looks like.

  2. Configure

    We set up your brand, domain, languages, cohort communities and the first round with you.

  3. Run one event

    Your next demo-day round or mentor week runs on your platform first.

  4. Grow

    Switch on courses, programs and paid office hours when you need them.

Your own database

Separate from every other organization. Founder data stays yours.

Modules on or off

Start with rounds and office hours. Add courses and payments later.

Export any time

Course progress, registrations and form answers to CSV or Excel.

Nothing to migrate first

Invite founders, mentors and investors by email. Your tracker can stay.

Start with one demo day.

Run your next founder–investor round as a pilot. We set up the roles and the rounds with you, then you decide.

Questions

What program directors ask first.

Something else? Ask us on the demo

Does the matching use our founders' sectors or interests?
No, and we'd rather tell you now. Matching works by role (two roles per room, Same or Opposite) or at random, always with no repeats. If you want fintech founders to meet fintech investors, run a separate room for that track.
Can mentors be paid through the platform?
Yes. Mentors can offer paid office hours, and the money goes to their own Stripe account. Or keep every office hour free for your founders.
Can each cohort be private?
Yes. Each cohort can be a private community with approval or a join form, and you can close the whole platform so only signed-in members see anything.
Do investors have to create a full profile?
No. Invite them by email and they sign in with Google, LinkedIn or email. If they come from your own site, partner SSO signs them in with one click.
We track the cohort in Airtable or Notion. Do we have to move?
No. Keep your tracker. BrainsMingle runs the live part: rounds, office hours, sessions, the community and the curriculum. Exports to CSV and Excel let you bring the numbers back.
How long does setup take, and what does it cost?
We agree a launch date with you on the first call, working back from your next cohort. The white-label platform is priced per user, with tiers that follow the modules you switch on. You get a written proposal after scoping.
