Saidler & Co.
Saidler & Co. was established in 2013 by Swiss entrepreneur Martin Saidler to manage the proceeds generated by his early-career exit of a jobs-platform business and the growth of his subsequent financial-technology firm, Numbrs. The family office has no disclosed external limited partners, giving it the latitude to back unconventional venture models, digital assets, and direct real estate without the constraints of a traditional fund lifecycle. Its Israeli investment operations are coordinated through liaison Boaz Barak, a former senior executive at Credit Suisse and UBS. Allocations span direct co-investments and special-purpose vehicles in fintech, agritech, media, supply-chain logistics, and sports and wellness. Technology focuses include artificial intelligence, consumer platforms, and blockchain-based financial infrastructure. The office deploys across seed and growth stages, with a geographic footprint that concentrates on European and African opportunities. Saidler & Co. has supported ventures alongside prominent co-investors; past participants in Numbrs include former Deutsche Bank CEO Josef Ackermann, ex-UBS Chairman Marcel Ospel, private-equity pioneer Sir Ronald Cohen, and the Investment Corporation of Dubai. Team size and total committed capital are not publicly disclosed. The platform extends into tangible assets through the Saidler & Co. Property Portfolio, which holds mixed-use real estate in Switzerland, Austria, and Hungary, and a commercial property entity in Trenčín, Slovakia. A digital-asset portfolio is managed alongside a research affiliate, Saidler & Co. Research AG, where Horst Martin Saidler and Severin Jan Rüegger hold board roles. The family maintains a philanthropic and research partnership with the Weizmann Institute of Science in Israel. The office's structural difference lies in its hybrid posture: it functions as a family office but retains the investing network and risk appetite of an operating founder's venture studio. Co-investing alongside sovereign wealth and former global bank CEOs gives it access to deal flow typically reserved for much larger institutional platforms, while its single-family structure permits multi-decade hold periods and opportunistic moves into real assets and digital currencies.

Frequently asked questions
Who runs investment decisions at Saidler & Co.?
Founder Martin Saidler oversees the family office's investment strategy, drawing on his background as a technology entrepreneur and founder of the fintech firm Numbrs. Day-to-day coordination of Israeli investments is handled by Boaz Barak, a former senior executive at Credit Suisse and UBS. Governance oversight includes board members Horst Martin Saidler and Severin Jan Rüegger at the affiliated research entity.
How did Martin Saidler generate the wealth that Saidler & Co. manages?
Saidler's wealth originated from the sale of an early internet job-portal venture and the subsequent growth of Numbrs, a financial-technology company that attracted co-investment from former Deutsche Bank CEO Josef Ackermann, ex-UBS Chairman Marcel Ospel, and private-equity pioneer Sir Ronald Cohen. The family office was formed in 2013 to steward the liquidity generated by these exits.
Does Saidler & Co. co-invest alongside external institutional partners?
Yes. The office has a history of syndicating with prominent institutional and individual co-investors. The Investment Corporation of Dubai, Josef Ackermann, Marcel Ospel, and Sir Ronald Cohen were all disclosed as co-investors in Numbrs, demonstrating Saidler & Co.'s ability to align sovereign wealth capital, global banking leadership, and private-equity networks around its core holdings.
What investment stages and geographies does Saidler & Co. target?
The office invests at seed and growth stages, with a geographic mandate centered on Europe and Africa. Its venture-style activity is balanced by direct real estate holdings in Switzerland, Austria, Hungary, and Slovakia, alongside a digital-asset portfolio. This breadth allows the office to blend early-stage technology exposure with hard-asset income streams.
Is Saidler & Co. structured as a pure family office or does it operate like a venture firm?
It operates as a single-family office with the investing posture and network of an operating founder's venture studio. Without external LP mandates, Saidler & Co. makes direct co-investments, participates in special-purpose vehicles, and holds alternative assets — including a digital-asset portfolio — under a structure that prioritizes permanent capital rather than fund-cycle liquidity.
What role does the Weizmann Institute of Science play in Saidler & Co.'s activities?
Saidler & Co. maintains a partnership with the Weizmann Institute of Science in Israel, reflecting Martin Saidler's philanthropic and research interests in the country. The relationship aligns with the office's Israeli deal flow, which Boaz Barak coordinates, but is kept organizationally separate from the family office's for-profit investment entities.
Does the office disclose its total assets under management?
No. Saidler & Co. has not publicly disclosed its assets under management or total capital deployed, consistent with the privacy norms of many single-family offices in Switzerland. Available public records confirm the existence of real estate subsidiaries, a digital-asset portfolio, and a research affiliate, but no aggregated AUM figure.
