Launch HN: Datrics (YC W21) – No-Code Analytics and ML for FinTech

Hey everyone, we're Anton (avais), Kirill (Datkiri), and Volodymyr (vsofi), the founders of Datrics (<a href="https://datrics.ai" rel="nofollow">https://datrics.ai</a>). We help FinTech companies build and deploy machine learning models without writing code.<p>We provide a visual tool to work with structured data by constructing a diagram of data manipulations from lego-like bricks, and then execute it all on a backend. This lets our users accomplish tasks that usually need a team of software engineers, data scientists, and DevOps. For instance, one of our customers is a consumer lending company that developed a new risk model using just our drag-and-drop interface.<p>I used to lead a large data science consultancy team, being responsible for Financial Services (and Risks specifically). Our teams’ projects included end-to-end risk modeling, demand forecasting, and inventory management optimization, mostly requiring combined efforts from different technical teams and business units to be implemented.<p>It usually took months of work to turn an idea into a complete solution, going through data snapshot gathering to cleansing to experimenting to working with engineering and DevOps teams to turn experiments in Jupyter notebooks into a complete application that worked in production. Moreover, even if the application and logic behind the scenes were really simple (could be just dozens or hundreds of lines of code for a core part), the process to bring this to end-users could take ages.<p>We started thinking about possible solutions when a request from one of the Tier 1 banks appeared, which confirmed that we’re not alone in this vision: their problem was giving their “citizen data scientists” and “citizen developers” power to do data-driven work. In other words, work with the data and generate insights useful for business. That was the first time I’d heard the term “citizen data scientist”. Our users are now these citizen data scientists and developers, whom we’re giving the possibility to manipulate data, build apps, pipelines, and ML models with just nominal IT support.<p>Datrics is designed not only to do ML without coding, but to give analysts and domain experts a drag and drop interface to perform queries, generate reports, and do forecasting in a visual way with nominal IT support. One of our core use cases is doing better credit risk modeling - create application scorecards based on ML or apply rule-based transactional fraud detection. For this use-case, we’ve developed intelligent bricks that allow you to do variables binning and scorecards in a visual way. Other use cases include reports and pivot tables on aggregating sales data from different countries in different formats or doing inventory optimization by forecasting the demand without knowing any programming language.<p>We’re providing 50+ bricks to construct ETL pipelines and build models. There are some limitations - a finite number of pre-built building blocks that can be included in your app, but if there is no block that you need, you can easily build your own (<a href="https://youtu.be/BQNFcZWwUC8" rel="nofollow">https://youtu.be/BQNFcZWwUC8</a>).<p>Datrics is initially cloud-native, but also can be installed on-prem for those customers who have corresponding security policy or setups. The underlying technology, the pipeline execution engine is rather complex and currently built on top of Dask, which gives Python scalability for big datasets. In the next release, we are going to support Pandas as well as to switch intelligently between small datasets for rapid prototyping and big datasets for pipeline deployments.<p>We’re charging only for private deployments, so our web version is free: <a href="https://platform.app.datrics.ai/signup" rel="nofollow">https://platform.app.datrics.ai/signup</a>. Try it to create your analytical applications with a machine learning component! We've put together a wiki (<a href="https://wiki.datrics.ai" rel="nofollow">https://wiki.datrics.ai</a>) to cover the major functionality,<p>We are super-excited to hear your thoughts and feedback! We're big believers in the power of Machine Learning and self-service analytics and are happy to discuss what you think of no-code approaches for doing ML and analytics generally as well as the availability of them for non-data scientists. Or anything you want to share in this space!

Launch HN: Worksphere (YC W21) – Manage flexible in-office or remote workspaces

Hey HN,<p>Aakhil, Theresa & Mark here at Worksphere (<a href="https://worksphere.com" rel="nofollow">https://worksphere.com</a>). Our software helps companies manage a safe workplace where employees can work flexibly in-office or remote. Worksphere automates desk reservations, safe entry, and gives companies office usage data to right-size their workplaces.<p>We previously worked together at Lish, a corporate catering marketplace startup catering (pun intended) to tech companies. Last March our revenue went off a cliff. No people in office = no lunch orders. We love our clients and our team, so we got to work on solving a new problem for our primary users - HR, Office, and Facilities Managers.<p>At the start of the pandemic, our users were struggling with how to return to their offices safely. New problems like enforcing social distancing, screening for COVID-19 symptoms, and contact tracing could not be solved at scale with existing tools. New coronavirus workplace regulations have cropped up, which are a pain and come with big financial risk if companies don’t comply (we’re looking at you CA businesses dealing with SB 1159 & AB 685 - learn more at <a href="https://www.worksphere.com/blog/covid-19/guide-to-ab-685-and-sb-1159" rel="nofollow">https://www.worksphere.com/blog/covid-19/guide-to-ab-685-and...</a>).<p>As the pandemic has continued (and continued, and continued) businesses are facing a new challenge. 75% of office employees report that they want a hybrid in-office and remote schedule. No one misses their 5-day-a-week commute. At the same time, collaboration and culture are hard to foster on Zoom and Slack alone. Employees still want access to an office when needed, but don’t want to come to work in an empty space. Businesses want the upsides of flexibility, but don’t want to pay for empty or only occasionally used desks — office space costs $10-12k per employee annually in major US cities. We believe that a hybrid workweek is a better workweek, and that an active approach is needed to make it a win-win for employees and businesses.<p>Our features help businesses reopen safely and realize the full potential of a flexible workplace. We automate the wellness surveys, contact tracing, and capacity limits needed to enforce internal safety guidelines and regional regulations. This alleviates a ton of manual work for Office and HR managers. Employees can create in-office schedules and see who else is in the office to increase collaboration. We track office utilization data so companies can make smart decisions about their office space and lease.<p>Worksphere is $6 per active employee/month, and our clients only pay for employees that come to the office.<p>If you’re one of the 3 of 4 people who wants to work flexibly post-pandemic, or if you manage a workplace, we’d love to hear from you. How frequently do you think you’ll need office space? What problems are you facing in this changing work environment? We’ll reply in the comments or you can email us at info@worksphere.com. Thanks so much for your feedback!

Launch HN: Ontop (YC W21) – Easily hire and pay remote workers in LATAM

Hi YC! We are Santiago Aparicio, Julian Torres and Jaime Abella and we are from Colombia. We are building Ontop (www.ontop.ai) to help companies do remote hiring and payouts, all the way from contract creation, to compliance documentation and easy money transfers.<p>COVID-19 has taught us all that remote works. Our bet is that companies in the US and Europe will start hiring more people in LATAM because talent is increasing in quality at a fraction of price compared to what they can get elsewhere.<p>Paying people in LATAM requires local knowledge to get the level of speed and compliance that workers need to get their money on time. We are building a solution so companies hiring in LATAM have to do less paperwork, can easily be compliant and disperse payments to different countries in a single place.<p>In our previous startup Fitpal (multi gym membership in LATAM) we experienced the pain behind signing contracts, collecting documents and sending money to different countries. We had to pay hundreds of gyms in LATAM and were frustrated by the amount of time we spent doing administrative work, when we should have been thinking on how to hack our way to growth.<p>We handle all paperwork, compliance and payments so onboarding new people is really easy. And most importantly, everything done legally, by the book, so that companies are always due diligence proof.<p>Our solution is tailored for LATAM guaranteeing the best speed and compliance in the market.<p>We want to hear your thoughts on our solution. We value feedback and case uses that you might have. Email us at founders@ontop.ai and we will personally give you a demo.

Launch HN: June (YC W21) – Two-click analytics reports on top of Segment data

Hi HN!<p>I’m Ferruccio, cofounder of June (<a href="https://june.so" rel="nofollow">https://june.so</a>). We make it easy to set up dashboards for your most important product metrics.<p>After a couple of years working in product teams, we realised that most companies measure the same things. So we created a set of templates that help you streamline the process of getting an insight from your data.<p>With Amplitude/Mixpanel you have to know what you should be measuring and how. Getting to an insight starts from a blank canvas, is intimidating, and requires some expertise. With June, you pick a template, connect Segment, select the right events for your analysis, and get a report.<p>We currently have 9 templates including Retention, Active Users, and Churning Users. We release a new one every week. We’re also starting to allow you to create and share your own templates.<p>To try it out, go to <a href="https://june.so/templates" rel="nofollow">https://june.so/templates</a> and pick a template you’d like to try. Connect your Segment account, select the events required for your analysis, and get your insights.<p>Looking forward to ideas and feedback from the community!
