Christian Reber

Who they are

Christian Reber is the founder of Wunderlist, Pitch, and Superlist — he sold Wunderlist to Microsoft in 2015, then rebuilt the concept from scratch as Superlist in 2020 while also launching Interface Capital, a Berlin-based VC fund.

Person

Christian studied Mathematics and Computer Science at FOM University of Applied Sciences (2007–2010) and started building things in parallel: Mucelli, a music service, in 2007, then Innovatics, a web and design agency, in 2008. In 2010 he co-founded 6Wunderkinder and built Wunderlist into a task-management app with over 6 million users before Microsoft acquired it in 2015 — a deal he has since publicly questioned on the 20VC podcast, asking whether the sale was a mistake. After a stint as General Manager inside Microsoft, he left and founded Pitch in 2018, a collaborative presentation platform that raised over $130M and reached a $600M valuation; he stepped down as CEO there in January 2024. He then turned back to the productivity space he knows best: Superlist, which he founded in 2020 with four other entrepreneurs including two former Wunderlist co-founders, positioning it explicitly as the unofficial successor to Wunderlist. Running alongside all of this is Interface Capital, a VC fund he launched in 2022 investing 300,000–500,000 euros per company in tech startups, with portfolio bets including Notion, Synthesia, and a seed position in Lilium (electric aviation) from 2016; he's also a founding investor in World Fund, Europe's largest greentech VC firm. Most recently he co-founded a gaming company in 2024, details still not public. He writes on Medium and at christianreber.com on product design, entrepreneurship, and the Wunderlist story; he has spoken at SaaStock, Slush, NEXT Conference, and the 20VC podcast.

Network

Reber's visible network skews toward European enterprise and finance circles — he has appeared at BCG's Reinsurance Executive Roundtable alongside Jean-Jacques Henchoz (CEO of Hannover Re) and Eric Andersen (President of Aon), with Nadine Moore (MD & Partner at BCG) as a close collaborator. On the investor side, his portfolio touches Notion and Synthesia, and he is a founding investor in World Fund. He is also publicly engaged with the EU–INC initiative, signalling an interest in European tech policy.

How they likely show up

Serial founder pattern (Mucelli → Innovatics → 6Wunderkinder → Pitch → Superlist → gaming company + Interface Capital) → operates in perpetual build mode; unlikely to be energised by maintenance or optimisation roles.
Left Pitch as CEO in January 2024 and immediately re-engaged with Superlist and co-founded a gaming company → short recovery cycles between major commitments, high restlessness.
Publicly questioned the Microsoft sale on the 20VC podcast → willing to revisit and critique his own decisions in public, signals intellectual honesty over narrative management.
Active on Medium and at christianreber.com on product design and entrepreneurship → comfortable articulating conviction in writing; probably responds well to written prep and specific references to his work.
Founded Interface Capital investing 300,000–500,000 euros per company → thinks at early-stage conviction scale, not growth-equity scale; bets on potential, not traction.
Founding investor in World Fund (greentech) and seed investor in Lilium → long-horizon bets outside his core product domain, suggesting he diversifies conviction across industries, not just productivity software.

Conversation tips

→ Reference a specific Medium post or a named argument from his 20VC appearance — he'll know immediately whether you've actually read his work or just skimmed a bio.
→ The Microsoft sale is a live question for him, not a closed chapter — ask about it as an open intellectual problem, not as historical trivia.
→ He operates across founder, investor, and operator modes simultaneously; clarify early which hat is most relevant to your conversation so you don't get a mismatched answer.
→ Don't flatten Superlist into 'Wunderlist 2.0' — the distinction between a genuine successor and a nostalgia project matters to him.
→ He engages with EU tech policy (EU–INC) — if the conversation touches on European startup conditions, he likely has a developed view worth drawing out.

Toolbox

Openers

Open on the gaming company he co-founded in 2024 — it's his most recent move and he's said almost nothing public about it, so asking what drew him there after years of productivity software is a genuine question, not a test.
Reference his 20VC appearance where he asked aloud whether selling Wunderlist to Microsoft was a mistake — that framing is unusual for a founder and signals something specific about how he evaluates decisions.
Mention Interface Capital's ticket size (300,000–500,000 euros) — it's a deliberate early-conviction stance, and asking how he chooses where to write that first cheque will reveal how he thinks about product and founder quality.

Discovery questions

When you stepped down from Pitch in January 2024, Superlist was already running — how do you think about splitting founder energy across companies that are both active at the same time?
Interface Capital backs companies at the 300,000–500,000 euro stage — what does a company need to show at that point for you to say yes, given you've been on both sides of that table?
Superlist is explicitly positioned as Wunderlist's successor — after watching Microsoft shut Wunderlist down, what does building the same category again feel like from a product conviction standpoint?

Avoid

Don't treat Wunderlist as his defining story and everything after as aftermath — he has founded five distinct companies since and actively resists the idea that the Microsoft acquisition was the peak.
