Juliana Coutinho/flickr.com Penny Kim, a marketing professional with a one-month career at a Silicon Valley startup, shared a detailed account of one of the ugliest startup stories we've ever heard.

Her tale started with a job offer in July of $135,000 a year plus equity and a $10,000 signing bonus for relocation expenses. (She was moving from Dallas for the job.)

It ended with her dismissal in August after she filed a complaint with the Division of Labor Standards Enforcement over failure to properly pay her, and an account of her month at the startup — which she did not name — on Startup Grind, entitled, "I Got Scammed By A Silicon Valley Startup." Her story has been a big topic of discussion on Hacker News for the last couple of days.

Business Insider spoke to Al Brown, former CTO and one of the founders of the startup, which was called 1for.one and JobSonic and recently renamed itself WrkRiot. (He's the one Kim called "Charlie" in her story.)

Brown confirmed much of her account, even the most outrageous accusation: The CEO she dubbed "Michael," whose LinkedIn profile identifies him as Isaac Choi, gave employees fake receipts for money wire transfers to convince them the company had paid their back wages when in fact it hadn't.

Until this week, the company was still in business and still had employees, Brown says. It's unclear if it still is or does.

When one of the company's advisers heard Kim's tale, he published the company's name, posted an apology letter, and declared he was no longer associated. Shortly after that, the company's website went offline.

The CEO and cofounder has not responded to Business Insider's requests for comment through multiple channels — email, social media, and phone.

The company's website, Facebook, and Twitter accounts were not online as of Tuesday morning, and its LinkedIn page has no contact information on it other than a headquarters address.

Caught in the lie

The most startling allegation is that the company tried to trick employees into thinking it had paid them back wages when it hadn't. In her account, Kim wrote:

"Thursday, August 4th was D-Day ... That afternoon in the office, Michael emailed each employee a personalized PDF receipt of a Wells Fargo wire transfer with the message: 'Here is the receipt. It has been calculated for the taxes on your semi-monthly salary and signing bonus. The money is arriving either today or tomorrow. I am sorry about the delay.'"

If the money didn't arrive in their accounts, the CEO told employees, it was a problem with the employee's bank and they needed to sort it out on their own.

Because the company was a month in arrears with their salaries at the time, and because this was such an odd way to get paid — not a payroll check, not even a cashier's check — an intern grew suspicious, Kim reported.

The intern quickly discovered that the receipts were fake. Someone had pulled an image of a wire transfer receipt from a Google search and photoshopped one for each of the 17 employees to make it look as if it came from a lawyer and was going into their accounts, paying the proper wages.

Meanwhile, Brown knew nothing about the wire transfers or any of the books, he told Business Insider.

He developed "lack of trust" issues with his cofounder around this same time, and a week ago on Monday, he quit the company.

"I'm out $230,000 plus expenses from April and back pay," he said. "I got pretty hurt here."

Brown met Choi through a trusted acquaintance. He's the brother-in-law of a former employee, someone he worked with and knew well. But Brown admitted a big mistake: He didn't do an extensive background check on his partner before launching the company.

The startup was still in the friends-and-family stage of funding, and looking for angels and seed investors.

Choi had promised Brown that he was investing $2 million of his own money into the company, but he had really put in $400,000, Brown says.

As Kim recounts, the CEO had convincing stories about why the rest of his funds were delayed, all while promising that he would have the money any minute, Brown says.

The startup was founded in November, and "everything was fine until April," Brown said. Employees and bills were being paid on time, "and we were growing."

By the end of April, the company was running short on cash and hadn't secured a seed offer yet.

"Every week, [the CEO] said the money was coming, but something happens — a long list of stories. I broached it in May and June with pointed questions, and I was not getting good answers," Brown said.

Two employees pitch in another $65,000

But Choi was so believable that he talked two employees into "loaning" the company cash, Kim wrote and Brown confirmed. One employee loaned the company $50,000 and another $15,000, Brown says, and that's how the company made its next payroll.

"I didn't find this out until August," Brown said.

Choi had told him that the cash came from a $500,000 loan his lawyer helped them secure. Brown had met the lawyer and, at that time, believed that the company had the remaining $500,000 in the bank.

But Brown says that in truth the company had plowed through $695,000 — between Choi's original $400,000, Brown's $230,000, and the employees' $65,000 — and didn't have a $500,000 loan from elsewhere.

An actual angel investor did invest in August, Brown says, allowing the company to pay its employees the month of salaries it owed them for July.

He adds that the company paid Kim's salary in full, which she confirms in her account, although Kim says she never got the signing bonus and has a quibble with the severance amount.

Rite of passage

Brown has been telling his side of the story, including posting a lengthy reply on Hacker News.

Woman walks children to Sherwood Elementary School along the Safe Passage route in the Englewood neighborhood in Chicago, Illinois, United States Thomson Reuters "To this day, I don't understand the game plan from the CEO. Why accelerate into a brick wall? None of it makes sense," Brown wrote.

One person on Hacker News offered this explanation:

"Welcome to the club. It's pretty much a rite of passage here to spend some time with a psychopath VC, a completely self absorbed CTO with a rich investor dad that fuels his fantasies, or an idiotic CEO with an ego problem, and to pay the price for it (just time if you're lucky, time+money if you're not)."

For her part, Kim said that if she had heeded the many red flags she saw at the company, she could have saved herself some heartache — but, she writes:

"There's this default human condition to trust others and give the benefit of the doubt ... There is also a default human condition to not give up ... I haven't given up on Silicon Valley or California, and I sure as hell haven't given up on good people."

Business Insider has reached out to Choi multiple times to hear his side of the story but have not heard back. We'll update this post if we do.
