Square Pie launched a Pie Bond on funding platform Crowdcube to help finance outlet expansion and to grow the brand's presence across more retailers.
Over 300 people have invested in the firm and the bond closed at 51.4% over its initial £450k target.
The firm had raised over £250k in the first two weeks from over 120 investors who invested from £500 to £10k.
Founder Martin Dewey (pictured) said the capital will enable the four branch openings planned for 2016.
Square Pie is a leading name for gourmet pies in the UK, and the brand was started from a market stall. It now operates six eateries in London, and supplies the likes of Tesco and Ocado.
The company is on track to hit net sales of over £5m for the 2015 financial year.
