I believe SHAKEN/STIR was mandated only for calls originating from within the US, however, most of these fraud calls are originating over VOIP (or SIP) from outside the US.

Coinbase is a publicly listed company, with all its assets & liabilities shared in quarterly investor updates. They store all customers assets 1:1 (ie does not re-hypothecate any of customer assets)

1. When we started to specialize in a vertical and created the narrative and the product for that vertical. This is esp. true in domains with many legacy players.

2. For some reason or the other, we have always had delays in announcing our fundraising rounds: both Seed and Series A announcements were delayed by 3-6 months. The moment we announced, we got a step magnitude more inbound customers. Lesson here is to not be a perfectionist and be willing to share the company/product publicly earlier, so you can incorporate customer feedback early.

PS: If it helps provide context for (1) above, our domain is fraud prevention; and we focused on payment fraud for Fintechs/Crypto instead of going after generalized fraud prevention across all categories like ecommerce.

Looks like they lost their ACH payments processor back in Dec 2020 leading them to prevent being able to handle ACH returns: https://abc7news.com/beam-financial-app-ftc-lawsuit-fintech/...

Handling ACH fraud is tricky. There is no decent dispute resolution mechanism in ACH compared to what Visa/MC offer for cards. So FinTechs and their backing bank are on the hook for customer reversals for up to 60 days. In the new FinTech revolution, this is one of the most misunderstood things. Many FinTech entrepreneurs think they can put up a nice UI and offer great interest rates only to get hit by huge fraud losses as soon as they launch. I run a fraud prevention startup for FinTechs - sardine.ai - and I hear of a new FinTech hit by fraud every week.

we are a stealth startup founded by former Paypal and Coinbase engineers. We have a device intelligence product that can detect accesses from proxies/VPNs without using any IP list. We can also detect the True OS that someone is using - useful to detect emulators and script kiddies. Happy to chat if of interest: info AT sardine.ai

Account recovery is a completely underserved problem today and many companies don't have a well thought through solution. Many rely on Knowledge Based Authentication questions that can be found easily by an attacker who has access to your email. To solve for cases where someone has lost all factors (forgot password, lost access to email, lost phone number), we need a brand new way of thinking about solutions. Hit me up if anyone's interested in brainstorming on the same!

for extra precaution, you might want to store TOTP secrets in a password manager thats separate from the one used to store passwords.

> The opportunity here for a startup bank is to replace credit card spending in the USA. The potential earnings are huge if you can get consumers to spend on a debit card instead of a credit card (because the rake is higher).

I think the converse is true. Card issuers earn 1 percent points higher interchange rates on credit cards (2.60%) than debit cards (1.60%).

Elad Gil's "High Growth Handbook" is a great resource.

Yelp is co-sponsoring a new Data Science Contest. Use Yelp reviews in Boston to predict whether a business will have a poor Health Inspection score.

Participate in this contest to help in an important social cause. Cities have limited budgets and currently send Health Inspectors to restaurants on an ad-hoc basis. Using the Machine Learnt models built via the contest, they would be able to assign Health Inspectors to restaurants more efficiently. Past models have shown high accuracy (82%) since Yelpers often talk about the same things that health inspectors look for – cleanliness, ambience, methods of preparation. The contest started yesterday and will finish on June 23, 2015. Winners will win cash prizes from a pool of $5,000.
