Co-founder Pitch

Last Reviewed: September 26, 2026

Executive Summary

Christian Reber is a German software entrepreneur best known for two products. The first was Wunderlist, the to-do app Microsoft bought in 2015 and later shut down. The second is Pitch, the Berlin collaborative presentation company he co-founded in 2018 as one of eight founders and ran as CEO from 2018 until January 2024. At Pitch he raised more than $130 million, reaching a reported $600 million valuation in 2021. In January 2024 he led a deliberate retreat from venture-scale growth: the company laid off two-thirds of its staff, returned unspent cash to investors, and aimed for profitability. He then handed the CEO role to co-founder Adam Renklint and kept a seat on the board. In between he announced Superlist, a productivity app he describes as Wunderlist’s unofficial successor.

Career Highlights

• Founded Wunderlist, which raised $35 million from investors including Sequoia and Atomico before Microsoft acquired it in 2015.
• Co-founded Pitch in 2018 and led it as CEO. Investors included Lakestar, Index Ventures and Tiger Global, and angels included the founders of Instagram and Zoom.
• Stepped down as Pitch CEO in January 2024. Co-founder Adam Renklint took over and Reber kept a board seat.
• Announced Superlist in May 2020 as Microsoft was closing Wunderlist, describing it as “a fresh new take on supercharged team productivity.”

Professional Journey

Reber founded Wunderlist, a to-do list app. It raised $35 million from investors including Sequoia and Atomico, and Microsoft bought it in 2015. Microsoft then decided to retire it in favour of its own Microsoft To Do. In September 2019, as the shutdown neared, Reber publicly asked Microsoft to let him buy the app back. It declined.

By then he was already building Pitch. It was founded in Berlin in 2018 by what the company describes as eight friends who “set out to make presentations better,” and he led it as CEO. Pitch was a collaborative alternative to PowerPoint and Google Slides, backed by substantial venture funding. It arrived in private beta in 2019 with $30 million in funding. Total funding passed $130 million from backers such as Lakestar, Index Ventures and Tiger Global Management, with angels including the founders of Instagram and Zoom, and the company was valued at $600 million in 2021.

In May 2020, with Wunderlist closing and Pitch approaching launch, he announced Superlist, a team productivity app. Coverage in 2022 described it as launched in 2021 with four other entrepreneurs, including two of his Wunderlist co-founders, and he called it the “unofficial successor to Wunderlist.”

The reset at Pitch came in January 2024. Reber wrote that being venture-backed in 2023 had been “insanely challenging” and that the founders had set “sky-high expectations” for the business. Pitch cut about two-thirds of its workforce, returned unspent cash to investors pro rata so that employees and founders held 80% of the company, and moved to pursue profitability and organic growth. On 8 January 2024 he announced that he was stepping down as CEO. Adam Renklint, co-founder and CTO, took over, and Reber kept a seat on the board. Pitch now describes itself as an agentic presentation platform with a team of almost 50.
