The complete story

The Story of Make Friends & Fire

From 2Tango to today: how a search for the perfect invitation became a ten-year journey of building clearer, warmer, lower-pressure ways to connect.

The Dream: It Started with Falling in Love

It did not start with an app, a business plan, or a technology. It started with someone falling head over heels in love - and one question: how do you make the perfect invitation?

Not by deciding for somebody else what should be fun, but by offering something they can choose from themselves. A personal menu: these are the things I would love to do with you; which one speaks to you?

That simple idea turned out to be much bigger than dating. It worked for friendship and spending time together, especially for people for whom social expectations, unwritten rules, or the possibility of rejection can take a lot of energy. Clarity can lower tension. Choice can create safety. And an invitation can feel like what it really is: an opening toward connection.

What followed was not a straight product roadmap. Each generation was rebuilt through new formats, communities and developers. Tjerk kept the underlying thread connected; Wybe Zeyl, Kees Heil and later Paulius Minialga made important digital generations possible, supported by Vincent and people around the Neurodiversity Foundation. The story began with love, but it grew through collaboration.

The developers in this story were more than people who wrote code. In each generation they took on a problem that many neurodivergent people know intimately: wanting connection while the unwritten rules around inviting, choosing, responding and showing interest can make that connection unnecessarily difficult. Their work was an act of care for the neurodivergent people using it now and for a new generation growing up with the expectation that technology can meet different minds where they are.

Together they kept searching for better ways to make an invitation easier and safer without making it dull: clearer, but also more playful, personal and exciting. The aim was never to make two people behave more typically. It was to give both people more room to show their unique selves, communicate preferences and boundaries, and meet each other from a position of strength.

The timeline

Nine generations. From an invitation on paper to everything we learned along the way in one definitive version.

The first paper menus and choice maps
2016 · before there was software

Paper · The First Invitation

The first version was literally made on paper. Tjerk was in love and wanted to invite someone in a way that felt personal without turning the invitation into a single high-pressure yes-or-no question.

The solution was a menu: these are things I would genuinely love to do with you; which of them appeals to you? The receiver could choose, combine, decline or respond from their own preferences instead of guessing what answer was expected.

That paper experiment contained the DNA of everything that followed. Make your own wishes visible, give the other person meaningful choice, and let clarity remove some of the anxiety that can sit around inviting and responding.

The first innovation was not digital. It was a different way of asking.

2Tango Dating · the invitation form
A paper idea becomes a repeatable format

The 2Tango Form

The paper menu became the 2Tango form. It gave the inviter a richer set of options and turned the original idea into something that could be used again and again.

Instead of one proposal, the receiver saw real alternatives. That changed the emotional logic of the invitation: a response did not have to feel like a judgement of the person asking. It could simply be information about preference.

The form taught us that structure does not have to make connection less romantic or spontaneous. Done well, structure can protect choice and make it easier for two people to be honest about what feels right.

For it takes two to tango: both people need a real voice in what happens next.

The first 2Tango.Dating web app
Wybe turns the concept into reusable software

2Tango.Dating · The Web App

Senior Developer Wybe Zeyl helped turn the invitation concept into a real web application. What had been a hand-built form became a digital flow that people could return to: choose, compose, invite and respond.

That was a major technical and conceptual step. The software could now carry part of the social complexity, remembering the structure so the people using it did not have to reconstruct every choice from scratch.

Wybe helped prove that neuroinclusive technology could be structured without being clinical. The experience could still feel playful and personal, while quietly doing the hard work of making choices and expectations easier to understand.

This generation became an important foundation for everything that followed. It showed that the original social idea was strong enough to survive translation into software.

2Tango events, workshops and choice-based connection
Taking the idea into real rooms with real people

Events & Workshops

The next question was whether the principles also worked away from a screen. 2Tango events and workshops created spaces where people could try the ideas together in real life.

Menus, visible possibilities and clearly named ways of participating reduced the amount of social guessing people had to do. The environment itself could explain some of what was possible.

These gatherings taught us that an invitation is not only a message before a meeting. The design of a room, an activity or a workshop can also make intention, consent and choice easier to express.

They also brought direct human feedback into the project. We could see where people relaxed, where they hesitated, what made them laugh, and which structures actually helped them move toward one another.

2Tango and Connect Zones at festivals
Testing the idea in the most unpredictable setting

Festivals & Connect Zones

The concept then travelled into festivals and parties. Different zones could signal friendship, dating, romance, relaxation or other forms of contact, including playful experiments such as a Hug Zone.

Festivals were almost the opposite of a controlled test: loud, busy, sensory and spontaneous. That made them unusually useful. If clear social design could help there, it had a chance of helping in everyday life too.

The lesson was simple and powerful: people do not always need more confidence or faster social improvisation. Sometimes they need clearer information about what is possible and permission to choose their own way into contact.

Together · activities, invitations and conversation starters
Kees builds a full mobile generation

Together · Android App

Senior Developer Kees Heil built Together, a native Android generation of the idea. Together expanded the project far beyond the original form, including 166 activities people could choose to do together.

It also added conversation topics and questions. The technology could now support several moments in one journey: finding something to do, making the invitation, and helping a conversation move beyond the first awkward minutes.

Kees brought the concept into a complete mobile product from a neurodivergent perspective. Calm, clarity and agency mattered more than adding pressure or pretending that everyone enjoys the same social rituals.

Together proved that the project was no longer one clever invitation format. It could become a broader toolkit for making connection easier before, during and after a meeting.

ietsdoen.nu · community, profiles and invitations
Tjerk and Wybe explore repeated connection

ietsdoen.nu · The Community App

With Tjerk and Wybe, the next generation became ietsdoen.nu: a community environment with profiles, communication and ready-made ways to invite people to do things together.

The community model made repeated contact possible and showed the value of remembering people, preferences and earlier invitations. It was an important experiment in what could happen after the first invitation.

But it also revealed a new problem: joining a community, making a profile or logging in can itself become a barrier. Someone should not have to become a member of a platform before they can simply answer an invitation.

That insight became one of the strongest design principles of the later product: the invitation must stand on its own, while accounts should add value rather than block the core experience.

The first Make Friends & Fire web generation
Paulius helps rebuild the idea as an open web tool

Make Friends & Fire · Version 1

Tjerk and developer Paulius Minialga of Skylark.dev, with support from Vincent, rebuilt the concept as Make Friends & Fire. This was not a cosmetic rename. It was a deliberate return to the smallest useful action: create an invitation and share it.

The account barrier disappeared from the core flow. Recipients could open an invitation directly, and a growing activity library helped answer the practical question that often comes first: what could we actually do together?

Paulius helped translate years of experiments into a modern web product. That generation gave the project a cleaner technical foundation and proved that the invitation itself could once again be the centre rather than a feature inside a larger community.

Version 1 was intentionally simpler than some of its predecessors. That simplicity was useful: it showed which ideas were essential and which ones could be reintroduced later only if they genuinely improved the experience.

The current complete Make Friends & Fire experience
Ten years of learning brought back together

Make Friends & Fire · The Complete Generation

The current generation is the result of looking back across the full ten-year journey and asking a disciplined question: what did every previous version teach us that is still worth keeping?

The strongest ideas were rebuilt into one coherent product rather than simply stacking old code on top of old code. Hundreds of activities can be discovered, searched and mixed. People can add their own activities. Invitations can be Personal, Group or Join Me. A Menu lets the receiver choose; a Full Program proposes a sequence.

Activity Mixer, the Wheel and guided discovery help when someone wants connection but does not yet know what to suggest. E-cards make invitations visual and personal. Fire Starter supports the moment when starting a conversation is harder than wanting one. Recipients can respond without first creating an account, while accounts add saving, reuse and personal history for people who want it.

This generation is therefore not simply a ninth interface. It is a synthesis of paper experiments, forms, Wybe's web app, events and workshops, festival tests, Kees's Together app, the ietsdoen.nu community and the first Make Friends & Fire web version.

The developers are part of that continuity. Wybe helped turn a social idea into reusable digital flows. Kees showed how deeply the concept could work on mobile. Paulius helped rebuild it as a modern open web experience. Each generation solved a different piece of the same human problem, and the current version is stronger because their work exists underneath its thinking.

After ten years of searching for better ways, the goal is still recognisable: help someone make a brave, personal first move while giving the other person enough clarity and freedom to answer as themselves.

Ten years of innovation, not to automate connection, but to make more room for real human choice.

A deeper look after the timeline

What ten years of 2Tango, Together and Make Friends & Fire taught us

Make Friends & Fire did not begin with an app, a startup plan or a technology. It began with someone falling deeply in love and wondering how to make an invitation that felt personal without deciding everything for the other person. That question became 2Tango: offer real possibilities, make desire and intention clearer, and let the other person genuinely choose. What followed was a decade of rebuilding that same human idea with different developers, formats and communities.

Deep dive 1

The dream: make the invitation worth saying yes to

The first idea was simple and romantic. Instead of asking one vague question or proposing one fixed date, prepare a menu of things you would genuinely love to do together. The other person could then choose what spoke to them. The invitation itself became an act of attention.

Deep dive 2

The first 2Tango dating menus

Early 2Tango experiments turned that idea into concrete choice-based forms and menus. They explored wishes, needs, boundaries and different types of dates. The core insight was already there: connection becomes easier when people do not have to guess what the other person means or wants.

Deep dive 3

From a form to real spaces

2Tango.Zones moved the experiment into physical environments. Different spaces could signal friendship, dating, romance, relaxation or other kinds of contact. Festival versions then tested the idea in busy, unpredictable settings and showed how much clarity can help when social signals are otherwise easy to miss.

Deep dive 4

From paper to web, and then Together

Senior Developer Wybe Zeyl helped turn the 2Tango principle into a web app, moving the early menus and choices into a reusable digital system. Senior Developer Kees Heil later built the Together Android app, expanding the concept into 166 activities, invitations, responses and conversation prompts. Together was increasingly shaped by neurodivergent experiences: less pressure, fewer hidden rules and more room to choose.

Deep dive 5

ietsdoen.nu: useful lessons from becoming a community

The next generation, ietsdoen.nu, experimented with profiles, communication and community. That phase taught an important lesson: the invitation should not depend on membership. The person receiving it should be able to participate without first joining a platform or building a profile.

Deep dive 6

Make Friends & Fire: the strongest ideas rebuilt

The current version is not a disconnected rebrand. Developer Paulius Minialga of Skylark.dev and Tjerk Feitsma rebuilt the live web generation, supported by Vincent and the wider project network. Useful ideas and functions from the earlier phases were reviewed, redesigned and reprogrammed into a modern codebase. Activity discovery, personal menus, clearer invitations, responses, groups, Join Me, conversation starters and saved context now live in one simpler system.

Deep dive 7

Built by different developers, not one anonymous product team

The technical history matters because each generation added a different layer. Wybe Zeyl helped establish the early web foundation, Kees Heil built Together as an Android app, and Paulius Minialga helped rebuild the current live web generation with Tjerk. Lana Kristine Jelenjev and many people around the Neurodiversity Foundation contributed ideas, feedback and continuity around the wider movement.

Deep dive 8

The principle that survived every generation

The names, developers and technology changed over the years, but the principle barely did: offer rather than pressure, make choices visible, reduce guessing and help somebody take the first step toward real connection.

Deep dive 9

Why that history still matters

Make Friends & Fire is not trying to become another dating marketplace. The decade of experiments pointed in the opposite direction: people do not need another layer between themselves and the person they want to see. They need practical help turning intention into an invitation, making choices visible and reducing the social guesswork around planning something together.

Deep dive 10

A neuroinclusive design direction

Later generations were increasingly shaped by neurodivergent experiences. That did not mean designing one special social script for autistic, ADHD or otherwise neurodivergent people. It meant taking clarity, visible choices, lower-pressure interaction and fewer hidden rules seriously - principles that can benefit many different people.

Questions about 2Tango and the transition

Is Make Friends & Fire related to 2Tango Dating?

Yes. Make Friends & Fire is a later generation of the same long-running concept that began with 2Tango Dating experiments in 2016.

What happened between 2Tango and Make Friends & Fire?

The concept evolved through physical 2Tango.Zones, festival tests, the Together Android app, ietsdoen.nu and multiple web prototypes before the current Make Friends & Fire version.

Can I still learn about 2Tango?

Yes. Historical material can also be found through 2tango.org, while this page explains how the concept connects to Make Friends & Fire today.

Is Make Friends & Fire still mainly about dating?

No. Dating was the original context, but the current tool is equally intended for friendship, groups, family and other ways of spending time together. The common thread is making an invitation clearer and easier to answer.

What makes the current version neuroinclusive?

The design emphasizes visible choices, clearer steps, lower-pressure ways to respond and fewer assumptions about one correct social script. Anyone can use the site; no diagnosis or identity is required.

The Work of Many People

Make Friends & Fire is not an idea that appeared in a single sprint. It is the result of years of building, testing, failing, adjusting, and trying again.

Tjerk brought the original concept and kept connecting the different generations. Senior Developer Wybe Zeyl laid much of the early digital foundation and later helped build ietsdoen.nu. Senior Developer Kees Heil turned Together into a real Android app from a neurodivergent perspective. Developer Paulius Minialga built the live web generation and the transition to Make Friends & Fire with Tjerk. Vincent and Skylark.dev helped make that step possible. Each developer worked in a different technical generation, but always on the same human question: how can the step toward connection become easier without taking people’s choices away?

Around the Neurodiversity Foundation, Lana and many others contributed time, ideas, feedback, experiments, and belief in the principle. The technology kept changing. The core barely did.

That is why we see the builders of these generations as part of the story, not as a technical footnote. Wybe, Kees, Paulius and the people who supported them each helped turn an obstacle their community encounters into something constructive. Every generation tried to return a little more agency to both sides of an invitation: the courage to offer something authentically, and the freedom to answer authentically.

Innovation here is not innovation for its own sake. It is useful when it lets people be more themselves. A good invitation can create anticipation without pressure, safety without sterility, and enough structure for two different people to discover each other rather than perform the same social script.

Attention and a little courage. Sometimes that is all it takes for something to begin. Now it is your turn.

Make your move.
