Paid on 18 August, the £4.3m dividend equates to a payment of £2.43 per ordinary share.
Nucleus is owned by a combination of advisers, its staff and investment firm Sanlam.
The company said its first dividend reflects a yield of 4.8 per cent and is a mix of an ordinary profit based dividend and a one-off distribution of historic surplus reserves.
David Ferguson, founder and chief executive of Nucleus, said: “This is another major milestone for Nucleus and one I am hugely proud of.
“Not only is it testament to the strength of the underlying fundamentals of the business, but also the passion, dedication and hard work of every single person who has been involved over the past eleven years.
“Following five consecutive years of increasing revenues and profitability that has seen the business become debt free with over £15m in cash reserves, Nucleus is better positioned than ever before to take advantage of the significant growth opportunities in the platform sector.”
In the first half of 2017 Nucleus saw gross inflows increase by 44.8 per cent to £1.3bn and assets under administration increase by 28 per cent to £12.8bn.
This resulted in revenue increasing by 26.5 per cent to £19.5m.
Nucleus was launched in 2006 and holds cash reserves of more than £15m.
Before the dividend had been paid this was more in cash reserves than has been invested in creating, launching and developing the core platform.
In July clients with between £500,000 and £999,999 on the platform saw their fees cut from 25 basis points to 17.5 basis points, while those with more than £1m invested had their fees slashed from 15 basis points to 5 basis points.
