A high-powered CEO and devoted mother-of-three was killed on March 23 when a vehicle carrying tourists lost control and overturned during a resort-organized tour in Nicaragua, leaving her young son fighting for his life.

Kasey Grelle, 41, was the founder and CEO of Aux Insights, a marketing consultancy that specialized in helping private equity firms grow and scale businesses.

Her 11-year-old son Julian was critically injured in the crash and airlifted to a children’s hospital in St. Louis, Missouri where he is now recovering from multiple traumatic injuries.

The tragedy unfolded as Grelle was traveling with her husband, musician Dave Grelle, and their three children on what was meant to be a family vacation.

Local reports confirmed the crash involved a bus that rolled over after the driver lost control.

Julian suffered severe injuries including head trauma, skull and spine fractures and a collapsed lung, and now faces a long and uncertain recovery.

In a heartbreaking Facebook post, her brother Andy Joyce said the family was ‘devastated’ by the sudden loss.

Her 11-year-old son, Julian, has been left in critical condition following the tragic accident

‘Kasey was one of the most brilliant, driven and selfless people I have ever met,’ he wrote.

‘She was relentless in everything she did, especially when it came to helping her people.’

Grelle leaves behind her husband Dave and their three children: Julian, 11, Kit, nine, and Des, six.

The family is based in St. Louis, where they live in a $796,600, three-bedroom, two-bathroom home. 

Friends say she was not only a devoted mother but also the backbone of her family, having stepped into the role of primary provider after her husband was seriously injured years earlier.

Grelle’s death comes after a life defined by extraordinary perseverance through repeated personal hardship.

In 2016 alone, she lost both of her parents within weeks, her father to pancreatic cancer and her mother to ovarian cancer.

Just months later, her husband was nearly killed after being struck by a car, and shortly after that, she gave birth.

Grelle previously led a major turnaround at digital media company Quillt, paying off $40 million in debt and overseeing its sale

Her husband Dave shared emotional tributes, calling her a ‘superhero’ and saying her death left ‘a hole in my universe’

At the same time, she stepped into the role of CEO at digital media company Quillt, inheriting a business saddled with $40 million in debt.

Despite the overwhelming pressure, she refused to walk away.

‘I was spending a lot of time running this company from a hospital room,’ she told Biz Journals in 2021, explaining how the experience reshaped her outlook and drive.

Under her leadership, the company transformed its strategy, paid off its debt and ultimately positioned itself for long-term growth.

Originally from Omaha, Nebraska, Grelle came to St. Louis while attending Washington University.

She began her career as a journalist, working as a reporter before pivoting into venture capital and business leadership.

She later founded Aux Insights, where she focused on helping private equity firms drive revenue and growth, building a reputation as a sharp strategist with a deeply personal approach to her work.

Colleagues described her as a rare leader who combined analytical precision with genuine compassion.

But those closest to her say her proudest role was always being a mother.

The family now faces mounting medical and financial challenges, with a GoFundMe set up to support her children and Julian’s recovery

‘Nothing made her prouder than being a mom,’ a fundraiser for her family said.

Her husband Dave shared a series of heartbreaking tributes following her death, describing a love story cut tragically short.

‘This can’t be real. I miss her so much,’ he wrote.

‘I thought we’d grow old together, always in love. We fought so hard for each other. We laughed so hard together.’

He added: ‘She was a superhero to our kids… There’s a hole in my universe.’

In another post, he urged others to cherish their loved ones.

‘Don’t take a day for granted. Live your life. Love your people. We did. I’m so glad we did.’

Julian, whose family have been lifelong Arizona Wildcats fans, has continued to show remarkable strength in the face of his injuries, joking with friends and tracking his March Madness bracket from his hospital bed.

The family is based in St. Louis, where they lived in a $796,600, three-bedroom, two-bathroom home spanning 2,706 square feet

In a touching show of support, Arizona Wildcats head coach Tommy Lloyd recorded a message for the 11-year-old, telling him: ‘I know you have a difficult road ahead, but I know you’re built for it… we’re gritty and we’re here for the fight.’

Meanwhile, Grelle’s two younger children, Kit, nine, and Des, six, are being cared for by family as they try to process the sudden loss of their mother.

A GoFundMe has been set up for the family as they face mounting financial and emotional challenges following her death.

They are dealing with significant costs, including Julian’s ongoing medical care and rehabilitation, medical evacuation expenses from Nicaragua, funeral costs and day-to-day living expenses after losing their primary source of income.
