Stuart Moss, Adam Woollard, both from Bracknell, and Charlie Ayling set up a fundraising page of crowdfunding website Indiegogo to help launch their company WeSayNo.
All profits from the company will go towards a variety of good causes, including homelessness, victims of domestic violence, child poverty and grants to local schools.
The group is seeking to raise £10,000 from the campaign, which will help pay for the equipment they need to make the clothing on-site and for initial batches of stock.
Once up and running, the company plans to sell a range of different clothing lines with unique designs, including hoodies, T-shirts, jumpers and beanie hats.
They also plan to buy camera equipment, which they will use to document all the people who benefit from the money the company donates.
Even though the company will start off helping people locally, the group aim to reach out to others in need in the rest of the country and abroad in the future.
Mr Moss, from Hanworth, said: “It has been quite exciting to get the project launched and it is going to be hard work but I think we’re ready for it.
“We want to buy some cameras as well so we can show people the work we do and show them that their money is going to the right places.
“We want to encourage as many people as possible to visit our page and help us reach our target to help us get started. We want to keep costs down to a minimum so more money goes to those who need it.”
Mr Woollard, from Great Hollands, added: “We Say No is the kind of company that’s needed as it helps those in need. The customer gets a physical representation of their donation and they know that they’re making a significant difference somewhere down the line.”
The campaign was launched on the website on Saturday and runs for 45 days, until Tuesday, April 15.
To encourage people to donate, the group has offered rewards depending on the amount of money given.
Rewards include wristbands and exclusive items of clothing. To donate, visit www.igg.me/at/wesayno
