This is a really really powerful concept – are you hiring?

Thanks! We are. :) Looking in particular for a strong backend engineer. Tech stack is python, aiohttp, redis, postgres (& timescaledb), k8s, terraform, aws (react, nextjs, swr on the frontend).

Know anyone?

If and when you become huge one interesting thing you might consider (if legal) is to become very liquid and actually allow users to trade stocks directly without selling to minimize tax. For example, if AMC is $1 and GME is $1, instead of buying the stocks directly we pay you $1.001 for both and you basically hold the stock for us. If we sell you sell the stock on our behalf and give us the cash and handle the tax f…

I think this is not illegal per se, but it's an equity derivative product which the SEC would not approve, since they don't approve CFDs which go a lot less far than this.

RIA's offer this kind of custom constructed direct indexing as a value add, so there's clearly a market amongst the broader non-active-trader types.

I bet you could lean into the huge and growing ESG ( Environmental, Social, and Governance) sector, because people have very different opinions about what "good" and "bad" are. For example most ESG funds are heavily weighted to social media, but maybe you think oil and social media are both bad? There isn't an easy to access product for that.

I love this idea and really dug Motif Investing back in the day (although charging for trades made it hard when weighing that vs. Robinhood)

Thanks! Yeah we were recently pointed to Motif by some of our early users. Have loved seeing their enthusiasm for it, hoping we can provide a great experience as well.

It was really sad to see Motif shut down. That service was awesome. It's made me wary of trying new services for this, since their shutdown led to a bunch of shuttling around of portfolios from different, much worse services (Folio, finally Interactive Brokers).

Your privacy policy is either borrowed from a previous iteration of the company (supply chain logistics?) or from a sample somewhere. You should fix that.

I work for a not-quite-YC* company adjacent to yours; I see some plausible symbiosis. I have an email address in my profile here -- reach out?

How is this for tax efficiency? Is rebalancing a taxable event? Or can you rebalance without selling by just redirecting new contributions to the underrepresented issues? Over time a buy-and-hold strategy with etfs gives a large compounding bonus since taxes are deferred.

We're exploring several rebalancing models at the moment (calendar rebalancing, constant proportion rebalancing, as well as only rebalancing with new contributions), and trying to understand which folks are more interested in. Which would you be most interested in? Definitely want to mitigate tax burden. Additionally, the direct indexing model does allow for more flexibility around loss-harvesting.

Only rebalancing by using new contributions would be preferred. My use case is re-creating the s and p 500 exclusive of some issues and with regular contributions for retirement.

Earlier quoted context omitted.

Would you consider expanding into e.g. derivatives? I was thinking a lot about this idea lately. An API/programmatic-first brokerage/trading platform. Let people design automated trading strategies on top of solid APIs, and use your site for visualization/planning. OptionAlpha seems to get into this but not nearly far enough. Latency wouldn't be critical either for retail investing. I don't really understand why it d…

Hey, thanks for checking us out. We want to get the UX right first with our existing feature set, and then consider expanding to more advanced things such as derivatives or options. We'll keep your request in mind! Also agree, re: API tooling. We'd love to find folks who want to write code against our API. Is that something you'd use?

> API tooling. We'd love to find folks who want to write code against our API. Is that something you'd use?

That's definitely what I'm thinking. There are so many tools out there to visualize strategies, profit/loss, scanners for various properties like IV, open interest, volume, etc in the case of options. But very few platforms go to the next level and provide good APIs to manipulate. It would be extremely impressive to offer both data and trade execution via modern APIs. I've wondered if that's an untapped market, or else why someone hasn't jumped on it :)

Rebranding stock picking as "index construction" is really quite disingenuous. I guess you're encouraging somewhat diversified stock picking, but honestly I'm dubious this is a 'good' idea for expected outcomes.

If you read Matt Levine's money stuff: a new favorite thing amongst financial products (currently only available to hedge funds, but on its way to becoming retail) is the following:

The default investment should be "the diversified market portfolio", e.g. S&P500. Then, if you have opinions (especially negative ones) about companies (e.g. if you are a perennial Tesla bear), you want to invest against those companies. A regular way to do that is to short. Shorting is hard and expensive for retail. A better way to do it is to buy everything in the S&P500 except TSLA. The way to do this is to construct a custom index that is identical to S&P500, except that TSLA is removed and all other weights are adjusted accordingly.
