👥 Employment Hero secures 2023’s largest capital raise

🇦🇺 SXSW touches down with mixed reviews, but the NSW Government is locking in another four years.

  • 🥛 Glass half empty: App issues, way-finding problems with a dash of long lines, and missed sessions left attendees feeling slightly disappointed for forking out $1200+ a badge. Check our Capital Brief’s review here.

  • 🍷 Glass half full: The SXSW attracted crowds from across Australia to participate in panels, discussions and after-hours events with an incalculable number of positive interactions for the ecosystem taking place. Measuring the value of events like this that connect people is hard and we’re glad SXSW is returning to Sydney.

Employment Hero sets 2023 funding record with $263M Series F at ~$2B valuation

In a standout Series F round, US investors have funnelled $263 million into Employment Hero, marking the largest funding of the year for a private local software firm. Employment Hero has just tipped over the 10-year-old mark and is just shy of a $2 billion valuation. This raise comes at a significant leap from its $1.25 billion valuation in the prior year’s round.

This round was led by a new investor, TCV (Technology Crossover Ventures), with participation from Insight Partners, AirTree Ventures, Seek Investments and OneVentures. TCV has previously backed giants like Spotify, Airbnb, ByteDance, LinkedIn and Facebook.

Employment Hero's platform assists organisations in managing employees through its HR software which handles payroll, governance, onboarding and turnover management. Recently, EH launched a "super app" called Swag to disrupt the online recruitment sector.

This latest funding round will be used for some aggressive UK expansion, targeting the crowded market to bolster its presence over the next 12 months. This capital provides years of runway, with Employment Hero stating it has minimal desire to go public anytime soon.


Skykraft snags $120M to improve Air Traffic communication with a constellation of low-earth orbit satellites

Canberra-based Skykraft has secured $120 million for its aviation satellite technology. The funds will help will help the team deploy a constellation of low-earth orbit satellites. These satellites are aimed at enhancing communication between air traffic control and aircraft over remote regions where traditional radio doesn't cut the mustard.

The latest funding round was backed by notable investors, including Main Sequence Ventures, Foresight Australia, and OPTrust, one of Canada's largest pension funds.

Although Skykraft is a technology business, CEO Michael Frater emphasised it should be valued as a transport infrastructure investment. The firm caters to clients with high credit ratings and is focused on long-term contracts, akin to traditional infrastructure located in space.

Skykraft plans to construct a global air traffic management service offering real-time communications for more efficient and safer flight paths. The system could also prove invaluable in emergencies, such as the disappearance of MH370. The crucial nature of the company’s tech was put on show just this week as details emerged about a near collision between Australian and Chinese satellites, which the Skykraft team was called in to assist with.

This raise follows a $3.5 million round from investors like former Macquarie Group boss Allan Moss and Lennoxgrove Capital.

Sahha secures $1.75M Seed round to provide insights on mental health via wearables

Sahha, a Sydney-based mental health tech backend API, has secured a $1.75 million Seed funding round. Sahha uses biosensors on wearable devices like smartphones and smartwatches to gauge indicators of mental health conditions such as depression and anxiety.

Sahha's platform plugs into the backend of various applications, delivering insights based on user behaviour and device sensor data. It correlates this information with a pre-existing dataset obtained from psychometric testing of thousands of global participants.

Founder Aleksander Dahlberg stated that the goal was to train machine learning models to find correlations between user behaviour and mental health conditions. The data is converted into a commercial API, which can be integrated into other platforms. Metrics like sleep regularity and phone usage throughout the night are assessed to provide insights into an individual's mood.
