Turnover in the year to July 31 rose from £2.76m to £3.7m, £100,000 higher than forecast, with a 29% increase in profits.
Chief executive Marc Davis hailed the success of SPD’s entry into the London market along with the launch of its executive education division.
He said conference income from delegates and sponsors had more than doubled to £2m as SPD expanded its portfolio of events, including staging 26 in the capital.
The firm aims to grow revenues to £12.4m and profits to £3m by 2020/21.
SPD, which is a subsidiary of the University of Salford, has increased staff numbers from 35 to 49 in the past year, and plans further recruitment over the coming months in its sales, marketing and operations teams.
The firm delivers events and training for individuals and companies across the UK and internationally, with a focus on sectors including health and social care, media, business and law, the built environment, education and public services.
Academics at the university provide the training, and profits generated by SPD are ploughed back into the institution.
Mr Davis said: “We have surpassed our promises and I am incredibly proud of what we have achieved.
He added: “The last financial year represented the beginning of a new dawn for SPD as I set about writing our five-year strategic plan with support from deputy chief executive Paul Bolton and chief operating officer Dave Hall.
“Our vision is clear; we will be delivering growth in partnership with the university.
“We represent a vehicle through which it can commercialise its expertise and offer an expansive engagement opportunity to delegates and industry partners, many of whom are first-time visitors to the university.”
