Sutro Pivots from Consuming Water to Swimming Swimming pools


Ravi Kurani is an engineer and former enterprise capitalist who launched Sutro, a water sensor producer, in 2012 in India. The corporate produced gadgets that measured consuming water high quality, a serious concern there.

He informed me, “We tried promoting to the Indian authorities. It was the stupidest thought ever. Don’t attempt to promote something to a authorities. It takes ceaselessly.”

Kurani’s resolution was to return to California, his residence, and pivot the corporate. Its sensor would goal swimming pool homeowners, not consuming water suppliers.

The pivot labored. Sutro is now thriving as a direct-to-consumer vendor and a expertise agency to chemical firms and pool suppliers.

He not too long ago described his journey to me. Our total audio dialog is embedded beneath. The transcript is edited for readability and size.

Eric Bandholz: Give us a rundown of Sutro.

Ravi Kurani: Sutro is a floating robotic that ensures your swimming pool and spa water are secure. It’s a small laboratory that detects your pH stage, chlorine, alkalinity — all in a easy app — so you already know what chemical compounds so as to add and when. For those who don’t have these chemical compounds, we join you to an area pool retailer to buy.

That, in a nutshell, is what we do.

Prospects should not have to know or program ranges of pH, chlorine, and extra. Our system is self-defined. It is aware of all of the complicated chemistry and arithmetic to get you to that proper stage. We think about many variables, such because the native climate or your beginning water chemistry.

Our system tells you precisely what chemical compounds so as to add. Our robotic doesn’t but put the chemical compounds within the water, though that function is coming.

Bandholz: Does your robotic keep within the water 24/7?

Kurani: Sure, that’s what we advocate. The machine’s algorithm learns over time how your water chemistry adjustments.

Bandholz: Your machine wasn’t initially for swimming swimming pools and spas.

Kurani: Sure, that’s appropriate. I was an affiliate at a enterprise capital fund in India. The fund’s major goal was to spend money on firms centered on applied sciences and merchandise for folk who make lower than $2 a day. Poverty is an enormous concern in India. Lack of meals and clear consuming water is a big drawback there.

A lot of our deal circulation was round consuming water filtration, however no person was water sensing. These gadgets price upwards of $10,000 again in 2011. There have been only a few firms that did water sensing. So we constructed our first water sensor in India round 2012. We tried promoting it to the Indian authorities. It was the stupidest thought ever. Don’t attempt to promote something to a authorities. It takes ceaselessly.

I got here again to California. My dad and mother as soon as owned a series of pool and spa provide shops. We flipped the enterprise mannequin round. Moderately than specializing in poverty, we determined to promote the sensor to wealthier communities, to people that personal swimming swimming pools and spas.

We’re nonetheless fascinated about ultimately fixing consuming water issues. Anyplace water purity is a matter, we need to be there.

Bandholz: Are you continue to VC-backed?

Kurani: No. We have been venture-capital-backed for the primary 5 years. In 2017, Sani Marc, a big chemical firm in Canada, acquired us. I now run that subsidiary.

Bandholz: Are you an engineer?

Kurani: Sure. My background is in mechanical engineering, with a minor in fluidics — using fluids to carry out analog or digital capabilities. I labored at NASA for a few yr after school. After which I acquired an MBA and labored within the enterprise capital business. Quite a lot of the expertise in our preliminary sensor is from my mechanical engineering and fluidics days.

Bandholz: You’ve shifted Sutro to give attention to swimming pools and spas. How do you promote your gadgets?

Kurani: We launched our first machine for that market throughout the pandemic. Every part we deliberate for distribution and retail gross sales modified. We rapidly adjusted to extra of an internet presence.

The pandemic was nice for us as a result of extra individuals have been at residence. Many constructed swimming pools and frolicked of their backyards. So our direct-to-consumer gross sales have been stable during the last two years. To seek out prospects, we use datasets from A number of Itemizing Providers of Realtors. We all know the place individuals with swimming pools dwell as a result of we are able to see a home with a swimming pool that’s been offered.

We combination that knowledge after which plug it into Fb and Google for advert campaigns. We even have retargeting campaigns just like typical ecommerce companies.

We’re now constructing a platform for pool shops to interface and talk with their clients. Eighty-five p.c of pool homeowners monitor water high quality themselves. They store on-line or go to a pool retailer to get their water examined.

We wish Sutro to be the Fitbit in your pool — an alarm that tells you if something is fallacious. The Sutro platform permits pool shops to see their clients’ knowledge. Prospects can then go to the shops and purchase the chemical compounds. We hope to launch the platform this yr.

Bandholz: How do you develop relationships with the pool shops?

Kurani: Sutro is the intermediary. We advocate chemical compounds. We work with chemical firms to make sure that we’re right-sizing their product for pool homeowners. That’s how we get into shops.

We’re not knocking on each pool retailer’s door. We’re working with chemical firms to assist them use the Sutro expertise to higher instruct the shops and their clients on what to place in a pool. That’s our mannequin.

Bandholz: I see so many alternatives for your small business. Of us in Flint, Michigan, might have used it, for instance, to detect lead ranges of their water. Even right here in Austin, residents have had water boil notices.

Kurani: Sure. We might distribute to that section in a few methods. We might promote on to people. They might connect our product to their faucet and measure the water in real-time.

However the higher method is to promote to municipalities. The U.S. Environmental Safety Company requires metropolis governments to check their water. However that might contain promoting to a governmental entity, which was our first drawback in India.

Bandholz: Inform us about your employees.

Kurani: We’re as much as about 50 staff members. The core group is simply seven individuals. The others are principally contractors in China that do our manufacturing. We’ve got a small group in Quebec at Sani Marc, our proprietor, doing the chemistry and lab work. Our internet and app improvement staff is primarily in Kosovo, north of Greece, with just a few in Mexico Metropolis.

These contracted companies do every thing from manufacturing to chemical work to internet and app improvement.

Bandholz: How do you handle such an prolonged staff?

Kurani: Having a venture supervisor is vital. That’s somebody who is aware of every thing throughout the group, roughly a chief working officer.

We break up the group by way of merchandise, akin to manufacturing, app improvement, and internet improvement.

Lastly, we be sure that Slack is a secure area. Engineers, particularly, are sometimes shy about speaking on Slack. We wish a tradition the place individuals can discuss something on that app. We’ve got face-to-face communication on Google Meet. However Slack is our place for day by day dialog and conversations.

Bandholz: What’s holding you awake at evening?

Kurani: Provide chain points. We will get merchandise made in China, however getting them to the U.S. is an issue. There’s a scarcity of delivery containers. Many ports are clogged or blocked.

Ramping up gross sales retains me awake, too. We’ve completed lots of promoting for model constructing. Our ratio of buyer acquisition price to lifetime worth is greater than traditional. I need to carry that down for profitability. The Fb algorithm change final yr hit us arduous.

Bandholz: The place can people attain out to you and purchase your merchandise?

Kurani: Our web site is We’re promoting our gadgets proper now. Hit the purchase button, and also you’ll have a Sutro in your home in three to 5 days. I’m on LinkedIn and Twitter.
