Welcome to our Log Book đ In here, you can find below a list of projects and tasks that the engineering team has performed over the past. This is neither meant to be exhaustive nor beautiful but to give a glimpse at what we do on a daily basis.
June 2025
Team size: 11
Projects:
- Whatsapp support We now sync whatsapp messages
- Team interation stats We now compute email stats across the team for more collaboration, updating all counting pipelines along the way.
- Container lifecyle rework We realised some of containers were shutting down a bit too harshly. We rework our container start/stop lifecyle to do that gracefully (like really gracefully)
May 2025
Team size: 11
Projects:
- Some things are cookingâŚ. đ¨âđł
April 2025
Team size: 11
Projects:
- Request processor Remember the task processor (back in Oct 2023), well itâs great but thereâs a lot of overhead for small tasks so we just added a request processor, dealing with 1 step tasks faaaaast
March 2025
Team size: 11
Projects:
- Onboarding revamp Because you do it every year or so. Itâs the best predictor or retention. Also we made it more intentional making it easier for user to understand what they build.
February 2025
Team size: 11
Projects:
- Notes are workspace level Taking notes on a contact used to be only visible in groups, leading to a break up in information. We have migrated notes by breaking this tie with groups and they now work at the workspace level, and added a privacy level personal/public, allowing for a broader understanding of the context of your contacts
- Messages are not tied to groups Same as above, message campaigns used to be only visible if you were part of the group and would be deleted if the group was deleted. The campaigns now life their own life (and are very happy like this). Some difficulties with rights & permissions.
- Removing orphan contacts The lifecycle of a contact led to case where contacts were orphan, not tied to anyone or any workspace. Dead data in your database that makes it heavy. We have reworked the contact lifecycle and contacts are properly cleaned now.
January 2025
Team size: 11
Projects:
- Follow ups Imagine that youâre never going to miss to reply to an email, weâve built a pipeline based on ai allowing to check that for you
- Gmail sender You can now use your Gmail account to send emails through our mailing tool. Quite efficient though tricky to do looking at Googleâs complex rate limiting system
December 2024
Team size: 12
Projects:
- LinkedIn and landing Attribution We are now able to correlate LinkedIn posts with sign-ups and the generated ARR to evaluate their performance. Weâre also able to correlate the first visit of our landing page. Pretty neat observability.
- Some performance improvements Because you gotta do what you gotta doâŚ
- View management Rework of our UI/UX for view management system for more clarity and better understanding. This is related to a general effort on making the app simpler/more readable.
November 2024
Team size: 12
Projects:
- Full email contents Now pulling full email contents and implemented a better access management.
- Spam management improvement We have spent some time working on improving the deliverability of our emails. This is a complete universe of its own âŚ.
- Display fields across primitives Itâs now easier than ever to display fields across entities: people fields on companies and vice versa. This involved a major change of our query builders.
Octobre 2024
Team size: 12
Projects:
- Revamp Roles & Permissions Rework our RBAC system to better support team.
- Selector-less extension We have reworked our extension to dynamically get the CSS selectors/Xpath allowing to work. This helps us be more reactive in case of CSS changes.
- Refactoring of email sending Better error management, code simplification, an overall cleanup for an identical feature set as before. Because it feels good to work on a clean and efficient codebase.
September 2024
Team size: 12
Projects:
- Objects second iteration Opened a second iteration on object after a beta phase.
- SOC2 preparation This is the final step before starting the audit in itself
- Optimised db usage We optimise our db strategy for our task processor, leading to reducing by 5 the size of the db, increased performance and reduce cost.
August 2024
Team size: 13
Projects:
- Reporting in app We start working on user analytics, build in app reports and dashboards.
- Sync engine We continue some explorations on the potential implementation of a sync engine to bring exquisite experience to our users.
- E2E and unit testing consolidation Thereâs always a point in time when tests become unstable or too long. We spent some time doing a full cleanup of tests.
July 2024
Team size: 12
Projects:
- SOC2 We are going for a security standard and have selected SOC2. We implement the first policies.
- Free-trial implementation We switched from freemium model to 14 days free trial.
- Change user email One of the main customer request finally gets released!
June 2024
Team size: 12
Projects:
- Objects We introduced a new primitive in the platform. We needed to make some space for it. Itâs only the first iteration.
- Free-trial implementation We switched from freemium model to 14 days free trial.
- Services cleanup We removed some services that have been replaced by the previous refactorings. This is getting us one step closer to remove GraphQL.
May 2024
Team size: 12
Projects:
- Filters support OR We needed to rewrite our query builder altogether to make this one work.
- Source synchronisation re-architecture With the growth we experienced we needed to rethinking how to scale our source synchronisation engine for emails and calendar events. More tasks in the tasks processor and good usage of kafka.
- Experience focus (continued) A lot of small things to improve and polish experience.
April 2024
Team size: 12
Projects:
- Company fields in people view Now displaying fields across models. Needed a rethinking of how the data flowed in the app.
- Redesign of the action toolbar Smaller, neater, more efficient!
- Improved global search More filters, simpler actions, easier to set up your workspace.
March 2024
Team size: 12
Projects:
- Compliancy We decided to get a security compliancy audit. We start gathering info to figure out which one and how.
- Group header revamp Fully reworked our group header in the app. Looks a lot nicer !
- E2E tests E2E tests are now properly set and running in the CI !
February 2024
Team size: 12
Projects:
- Kanban ranking improvements Our kanban views needed some improvements so we updated the way we compute lexoranks.
- Monorepo Our monorepo is fully implemented!
- Experience focus (continued) A lot of small things to improve and polish experience.
January 2024
Team size: 12
Projects:
- New onboarding A brand new onboarding to improve how we welcome users in the app.
- Fixture scenario We started working on a tool to import complex fixtures to test some scenarios. We decided to drop it as it was not really improving quality in the end since injecting fixtures is hard to maintain and not realistic. We opted to go for proper E2E tests.
- We opened some important projects đ
December 2023
Team size: 11
We spend the month finishing feature projects and preparing for the next year !
November 2023
Team size: 11
Projects:
- Make support We are now supporting Zapier and Make. With triggers (webhooks) !
- Monorepo Our monorepo is fully implemented!
- Experience focus (continued) A lot of small things to improve and polish experience.
October 2023
Team size: 10
Projects:
- Hard limits Implemented refined hard limits in the product to protect performance.
- First task in the task processor Implemented our first task in the task processor: duplicating a group.
- Experience focus A lot of bug smashing to improve and polish experience.
September 2023
Team size: 10
Projects:
- Task processor To deal with long and complex multi step tasks that can be a bit heavy on the platform, we have decided to implement our own task processor. We can handle the load better and decided to not spread the business logic everywhere. Weâre a bit more relaxed now.
- Live updates Complete revamp of our live updates (web sockets) implementation. More granularity, more security, more everythingâŚ
- Reverse ETL More use case for our reverse ETL. We send analytics this way from our data warehouse. Itâs more simple this way and removes it from the application. Sweet.
August 2023
Team size: 9
Projects:
- Observation improvements We have more things to look at, Real User Monitoring and we are also working on improving our logs. Seeing is goooood. đ
- Multiprocess We can now optimize our instances by easily start multiple processes in one container. Cost reduction and better usage of ressources is something we care for.
- Kanban improvements Amount aggregation to compute the sum of certain fields in column. Something of high importance for sales use-cases đ¤
July 2023
Team size: 9
Projects:
- Desktop app Finally, a desktop app that is an alternative to the web app. Built with vitejs.
- Filter by any field Itâs now possible to filter by any field. Something enabled by our refactoring of our custom field architecture last May.
- Notification center Users are now notified in-app on certain events: reminders, assignments, etc⌠Teamwork is now more visible.
June 2023
Team size: 9
Projects:
- New sidemenu A major rework of our sidemenu, with now expand/collapse mechanism, reordering and even favorites!
- Automatic deletion of inactive workspaces For users that have created an account but donât actively use it, we decided to delete it after some time. As a user, we appreciate product that removes our data so that it doesnât stay indefinitely on their servers. Also it reduces the db size.
- Move duplicate infrastructure Simplify and reduce the cost of our duplicate detection algorithm by removing it from Airflow and dealing with duplicates in near real-time.
May 2023
Team size: 10
May was the time for a major refactoring of our custom field architecture to make it more flexible and allow it to scale.
Projects:
- Magic fields. Ask AI to generate (virtually) whatever you want, based on the data you have stored in folk. E.g. create custom icebreakers for each contact, write emails, or whatever you might need.
- Automatic deletion of old accounts Nobody likes their data to be kept forever in a product if you donât use it. We now delete it automatically after some weeks of inactivity.
- Refactor custom fields A major architectural refactor to allow the stack to stay clean, fast and nice to navigate.
April 2023
Team size: 10
Recent breakthroughs in AI have made all the below possible in folk, and weâve made folk more intelligent than ever before.
Projects:
- Library of templates. Pick and template, customize, and set up your CRM in minutes, not days. We have templates for deal-flow CRM, partnerships management, lightweight ATS, lightweight CRM, and much more.
- Outlook full integration (incl. emails and calendar events) You can now sync your Outlook account to folk, in addition to Gmail.
- Mobile-friendly. You can consult your contacts & groups directly on mobile.
- Google security audit We are compliant!!!
March 2023
Team Size: 10
Projects:
- Outlook contacts integration Now importing contacts for Outlook accounts. Next step is importing interactions. A big challenge as 50% of our users are on Outlook.
- New table A sped up more convenient and accessibility first table is now implemented. Easy navigation, copy-and-pasting and drag-and-pasting. Getting us closer to the way a spreadsheet works which simplifies our usersâ workflows.
DevX:
- fully migrated to pnpm Easier dependency management and no more switching between yarn and pnpm. What a relief!
- More logs and dashboards Added more logs and added some dashboards to help with monitoring and debugging
- Fix sources bugs Google added twice would create some weird behavior. Took a bit of time but itâs finally fixed
February 2023
Team Size: 10
Projects:
- Authentication improvements A lot of improvements for our authentication. Most visible features? Replaceing code validation with a magic link, sessions management, user can change their account email. Just like you expect it.
- ACL Our ACL just got a good refurbishment that will allow a more granular approach on rights. This will unlock many things, like preventing anyone from flooding our hiring pipelines with comments like âWe need this person!â, âLetâs hire him!â, âWhy havenât you hired him already?â, âHelloooooooooo?â
- Log an interaction Users can now manually add an interaction to a contact like: Iâve had a coffee with this guy. Coffee was terrible, the opposite of this meeting âŚ
DevX
- Code generated mocks We now code generate our mocks in the front end. No more writing mocks manually that are not up to date with our API. Hurraaaaay !!
- Db logs Weâre now completely up to date on our db engines. Side-effet? We get db logs and we have starting identifying improvements opportunities on our requests and indexes. Feels like we have gained the sens of sight OO.
- Combobox refactoring We refactored our comboboxes. They used to be really annoying but now they are nice and gentle. Just like when a teenager becomes an adult.
January 2023
Team Size: 10
Projects:
- Attachments in comments You can now add a funny picture in a comment on a contact.
- Pricing improvements An overall better management of our payment flow with better trial periods so you can ⌠try more! (But donât forget to pay)
- Enrichment in folkX folkX also gets to enrich your contacts. Itâs a strong member of our family and contributes well
DevX
- Rolling out pnpm Better monorepo management with pnpm. As always with this kind of tasks, it starts easy until it gets really tricky.
- Db upgrades Upgrading the versions of our dbs because more recent stable versions are available and we like being up to date.
December 2022
Team Size: 9
Projects:
- Email attachments Itâs great to be able to send emails within folk but is it really useful if you canât add that cute little gif showing a hug between a dog and a goose
- Improve our duplicates detection system Why clean your data when we can do it for you?
- Sort by any fields - part 2 Allowing to sort your data by any field you want is a commodity feature. It is now possible to filter by ALL fields including the ones created by our users. Now completely finished.
- Improved CSV import Importing companies and their custom fields properly. Confirm the mapping and let the magic happen â¨
DevX
- Moving all our chrome extension builds to the ci Making sure everything is automatically built and traceable
- Monitoring improvement Automatically monitor all of our routes properly, see trends and raise alerts.
November 2022
Team Size: 9
Projects
- Contact enrichment via DropContact We have integrated DropContact to enrich contacts with emails, phone numbers, job titles and position gathered on the web with their stateless technology. Enrichment requests are made by our users and the data is automatically populated as soon as it is available.
- Sort by any fields Allowing to sort your data by any field you want is a commodity feature. It is now possible to filter by ALL fields including the ones created by our users.
- New search page This new search allows our users to see the whole of their data to smoothen the creation of contact lists where the magic happens in folk.
- Definition of active user It is of utmost importance to us that we clearly understand who our users are and what they need and want. Itâs not an easy job in a PLG business and it starts with clearly defining what an active user is and identify them so we can bring them even more value.
- Mobile webapp What can we say about this one? Itâs pretty obvious that itâs nearly for a business like ours not to be available on mobile.
DevX
- Strengthen security We have done a round of security improvements.
- Improve web sockets resiliency WebSockets can sometimes be capricious and terminate. We have improved their resiliency and they are now wiser than ever (and donât disconnect).
- Improve architecture processes Making sure we are all on the same page about how we want how architecture and stack to grow is very important to folk. So we made sure to have a lightweight process that keeps everyone aligned. Async notes and a short sync meeting make sure everybody knows what they should know.
October 2022
Team Size: 9
Projects
- Templates library Starting with a new tool can be tricky: empty workspaces and writerâs block can happen pretty quickly. Applying templates gives you examples and a feel of the power of folk. Even better, the community is not far behind.
- Entri for DNS records Setting DNS records to authenticate emails and avoid behind identified as spammers is essential when you are doing marketing campaigns. But itâs such a hassle. Entri makes is easy to propagate DNS records so everything works smoothly.
- Automatic acquisition channel performance analysis Being a PLG product, we need to know what acquisition channels are working and which are not. We have automatized all this and get consolidated views. We feel like growth hackers and it feels good!
- Deploy first Kafka use case Kafka is here and we are using it in production now đ Itâs a big step forward as it will help us grow our architecture.
DevX
- Write runbooks We now have a complete documentation describing our domains and deployment units, how to deploy them and their dependencies. We also know what to do when they donât work.
- Monitoring utils package Tooling to simplifying our monitoring. It feels good to easily see clearly.
- Start using AWS spot Because money is money.

Projects
- Messages statistics Nothing is more frustrating that sending an email campaign have and no idea if it was successful. Itâs now possible to track delivery and open rates. Ooooooh yeah!
- In-app payment Because money is money.
- Add a search on our Chrome extension So far you could only fetch the information of the opened LinkedIn profil. Now you can display in our Chrome extension any profil from your workspace.
- Onboarding AB test Quick AB test to see if it was worth it to remove an onboarding step. Guess what: it was not.
- Made public views responsive Because you open them from your mobile sometimes. A mobile phone is that thing always in your handâŚ
DevX
- Optimize DB sizes Performance is key. DB sizes is part of this game.
- SQS package Extract utils in a package to deal with SQS queues. Simpler, easier.
- Update to React 18 Oh boy! Thank you Antoine (T) for this one! One for the team đ
August 2022
Team Size: 10
Projects
- Share views publicly You can now share some of your folk data publicly. You share a link, people can see some nice tables with interesting information.
- Add contact strongest connections Wanna know which of your colleagues knows this cool guy best? Well we compute that for you. You can now ask for a recommandation or try to get closer to the cool guy (but donât say anything).
- Refactoring: preparing the introduction of Kafka in our stack We see Kafka as an step forward in our architecture but one does not simply add Kafka in their stack. This was a major refactor; it clarified how we wanted to deal with data from now on.
- Data Warehouse We have our own datawarehouse! We have our own datawarehouse! Thanks Alex!!
- Optimized merge contact route from ~1.5sec to 300ms Because time is money.
DevX
- Set up VPN access in replacement of IP whitelisting No one likes to update an IP whitelist.
- Improved prioritization system of technical projects How do you prioritize getting rid of ternary operators against having braces inline with if? Now we know.
- Set up internal CI runners Sped up CI jobs and itâs also cheaper.
