kayhi··on How to start a lab when funds are tight
Great point that there are new lab and volume discounts. Our data is showing that you should always be negotiating and that pricing is still independent of volume. We've seen cases of companies with 1/10th the spend of others getting better prices by product and overall.

This line from the article made me smile...

"Besides, there’s often no need for aggressive negotiation tactics; most suppliers will accommodate reasonable requests to secure the business of a newly hired faculty member, notes Lisa Witte, president of Fisher Scientific, a lab-supply company in Pittsburgh, Pennsylvania."

Of course a person in sales is going to tell you not to negotiate aggressively with them.

A major problem is that it is time consuming for researchers to comparison shop and contact sales reps. We built Lab Spend (https://labspend.com) which has a pricing search engine for supplies and chemicals to give people an idea if their quote is fair.

"On Amazon, a $100 roll of paraffin film sells for around $25." Seems reasonable

kayhi··on Berkshire Hathaway 2017 Annual Letter [pdf]
Correct, they are paying essentially 0% interest in exchange for the policy risk.

My interest is that the policy risk according to Berkshire actions is less than 4% debt they could likely attain (or better). In other words - they are recommending investors not to use leverage, but in a sense they do use it against policy risk.

The trade off between debt and policy risk is interesting as both greatly increase returns by leverage.

kayhi··on Berkshire Hathaway 2017 Annual Letter [pdf]
I’ve been torn about his comments of not using leverage to buy stocks. Berkshire uses insurance float which has risk. I guess they feel that this risk is small and supported by the 400 billion reserved to pay out.

Is attaining debt at a 4% rate mortgage riskier than utilizing their float?

kayhi··on Launch HN: Nutrigene (YC W18) – Tailor-made liquid supplements using health data
Controlling for purity should not be a major problem and should be a baseline for being in the food business. Lifestyle (diet, sleep, stress, alcohol consumption, disease, genetics, etc.) will far outweigh the variable of supplement purity.

I hope you find more studies, but the variables such as those mentioned above will make it very difficult to determine causation.

kayhi··on Launch HN: Nutrigene (YC W18) – Tailor-made liquid supplements using health data
Thanks, but these references are reporting demographic and biochemical indicators. They do not state that people with a normal diet need supplementation.

Summary reference:

"The Nutrition Report has limitations. First, it does not cover information beyond biochemical indicators, such as dietary intake, supplement usage, hematologic measurements, and anthropometric body measurements, which are generally used together with the biomarker information to comprehensively assess nutritional status."

"forfeit insight into the association between variables unique to each individual biomarker"

Can you link me to the reference that states people should use supplements who have a normal diet?

My point was that athletes are using their bodies in the extreme do not require supplements.

Discovering new findings with me is usually fine, but am nervous when it involves my health.

kayhi··on Launch HN: Nutrigene (YC W18) – Tailor-made liquid supplements using health data
Supplements feel like one small step above homeopathy

I've interacted with hundreds of elite level athletes who are always looking for an edge. These athletes do not depend on supplements and many avoid them. I would expect these athletes to be on the cutting edge and results to trickle over to 'normal' people. If these athletes who are more in-tune with their bodies than most are avoiding supplements than am not seeing a lot of upside for the average person. If you are deficient or have a medical condition then sure, but the focus should be on healthy eating. Supplements are not going make up for eating poorly and likely just results in expensive urine or placebo effect for most people.

It's hard to debate since everyone is using anecdotal evidence.

kayhi··on Instacart has raised another $200M at a $4.2B valuation
My concern is the price of getting the product at the store verse instacart delivering it.

If you can get a discount directly from the store, great! You are providing value to them.

kayhi··on Instacart has raised another $200M at a $4.2B valuation
Never used Instacart, but your link to show transparency, doesn't actually state what the mark up is.. 2%, 10%, 25%, order minimum or there's fee..

Transparency to me, would mean I place order and know how much it will cost, instacart mark up, service fees and if a tip is included.

eBay is decent for used equipment some glassware, but would not recommend it for chemicals.
kayhi··on YC Bio
Awesome! We've been supporting start up bio companies by offering them a fair pricing on equipment, supplies and chemicals. I think we've sold to every YC bio company except Ginkgo (doh!).

There's a huge problem in non-transparent pricing for products. For those outside the industry it's like buying used cars, dealing with sales reps and everything is a quote. Researchers are at a huge informational disadvantage when it comes pricing.

Example, acetone which is a commonly used solvent:

$900 vs. $300

Another example, IPTG:

We commonly see 3-5x differences and up to 10x for the exact same item. This makes a huge difference when you're in the range of 500k to 1 mil from YC Bio.

kayhi··on Dustin Moskovitz pours funds into high-risk research
The problem is creating many hurdles to purchase.

For example, a contract gives the scientific distributor the right to match a price [1]. Scientists need to make this request through their procurement office or to a sales rep. which takes a couple of days and additional paperwork to complete. These extra steps create enough friction that researchers will often by through contracted providers despite them being more expensive.
