About the Company

In 2022, three co-founders in Lausanne set out to solve a long-standing challenge: bulky waste disposal was slow, expensive, and inconvenient. They therefore launched Big Sack: heavy-duty waste bags for businesses and households, backed by a nationwide network of transporters and certified recyclers. At the core is a fully automated waste management platform that enables fixed-price bookings, real-time tracking, and higher recycling rates. The result is waste disposal that’s faster, simpler, and more sustainable, bringing long-overdue transparency and efficiency to the industry.

Benefits for Co-Owners and Investors

As a co-owner of Big Sack, you benefit from the following advantages:

• First mover advantage: In a market dominated by outdated dumpster solutions, Big Sack is the first to deliver a fully digital bulky waste disposal service. This head start creates a unique opportunity for investors to back the category leader early on.

• Strong and visible brand: Our signature yellow bags are already a recognizable presence in the Swiss waste market. This brand equity builds defensibility, customer trust, and long-term value that competitors will find difficult to replicate.

• Exclusive logistics partnerships and wholesale footprint: We have secured exclusive agreements with key logistics partners, ensuring reliable operations and barriers to entry for competitors. In addition, our presence in more than 30 wholesale stores gives us a strong physical footprint that drives visibility, accessibility, and adoption.

• Recurring and diversified revenues: Our platform model ensures high customer retention and repeat orders across both B2B (70 percent of revenues) and B2C segments. This creates predictable cash flows and resilience against market fluctuations.

• Sustainability as a competitive edge: Every Big Sack pickup is tracked, sorted, and recycled, directly improving Swiss recycling rates and aligning with tightening environmental regulations. This measurable impact strengthens our positioning with municipalities, corporates, and ESG-focused investors.

Our vision - Why invest in Big Sack?

Waste is one of the most polluting industries in the world, and bulky waste is among the least efficiently handled. Old-fashioned dumpsters and opaque processes make disposal slow, costly, and environmentally damaging. Big Sack was created to change this. Our vision is to become Switzerland’s leading alternative for bulky waste disposal: fast, simple, and measurable, proving that sustainability and profitability can go hand in hand.

Our bright yellow bags are already a familiar sight in Romandie, paired with a digital platform that ensures every pickup is booked at a fixed price, collected within 24 to 48 hours, and traced all the way through recycling. This combination is transforming the customer experience, creating recurring revenue streams, and delivering transparent data on recycling and emissions. For the first time, households and businesses know exactly what happens to their waste.

But we are only at the beginning. With support from this crowdinvesting campaign, we will accelerate our nationwide rollout, strengthen our presence in the Swiss German market, and invest further in technology to fully automate waste collection and reporting. This financing will allow us to scale faster, improve margins, and position Big Sack as the trusted national brand for sustainable bulky waste management.

Our ambition does not stop at Switzerland. Demand for smarter, cleaner waste solutions is rising across Europe, and the Big Sack model is designed to scale. With continued innovation and the right partners, we can bring our platform abroad, raising recycling rates and setting new standards for compliance and transparency.

By investing in Big Sack, you are not just funding a business. You are joining a movement to modernize one of the dirtiest industries, to build a more circular economy, and to make waste management faster, simpler, and more sustainable for everyone. Together, we can capture a growing market while making a measurable difference for the environment.

FAQ

Why did you choose crowdinvesting for financing?

We want our customers and supporters to be part of our journey. Many of our early investors are also clients who believe in our model and values. Crowdinvesting allows us to expand this circle - turning satisfied users into co-owners, strengthening our community, and ensuring that growth is shared

How did you come up with the company valuation?

The 27 percent increase in valuation from our Seed 1 round last year is a fair reflection of Big Sack’s strong momentum. We have delivered high revenue growth year-to-date, expanded our wholesale footprint to more than 30 active locations including Baubedarf, Jumbo, Bauhaus, and Gétaz-Miauton, and launched our automation platform DumpLink, now covering the majority of our shipping volume. These achievements strengthen our market leadership, improve margins, and establish a solid foundation for accelerated nationwide scaling.

Do I get voting rights?

Yes, you will have the right to vote. We will also group our smaller investors together to give them greater collective power and influence.

Will I receive dividends?

While we do not plan to distribute dividends in the near term, we do not exclude this possibility in the future, as our business model and ability to reach profitability quickly could make it a viable option.

Is an exit planned?

Yes, an exit is part of our long-term strategy. Our immediate focus is on nationwide scaling and achieving profitability, but we see clear exit potential through a trade sale to a strategic buyer in the waste management, logistics, or construction sectors. Comparable companies in these industries have exited at revenue multiples of 3 to 6 times, which provides a solid and conservative benchmark for value creation.

At the same time, Big Sack is more than a traditional waste operator. Our DumpLink platform, automation, and data-driven reporting bring a strong technology angle to the business. Tech-enabled players with recurring revenues, ESG impact, and clear scalability often achieve higher multiples, in the 6 to 10 times range. This upside reflects the potential premium attached to our model once traction and profitability are fully established.

By investing in Big Sack, you back one of Switzerland’s fastest-growing ConTech startups and help transform one of the country’s most polluting industries. Top supporters gain access to exclusive rewards, from custom merch to free pickups and private meetups with our founders. Be part of the change, one Big Sack at a time.
