Problem: The cumbersome booking of the wrong psychologist In Denmark, mental disorders account for 25% of the disease burden and cost society 55 billion DKK annually with more than 2,000 people receiving therapy from a psychologist every day. Further, too many individuals do not receive timely help as they cannot cope with the draining 5-hour process it takes to find and book a psychologist. At the same time, U.S. experience shows that only 20-40% of people find a psychologist they trust and have 'chemistry' with. This is tragic, as just one bad experience can cause a client to completely drop out of or postpone his/her therapy. The ineffective booking process and the risk of a poor patient-therapist match mean that many people continue to struggle with mental illness who could otherwise be treated. This has major consequences for individuals whose mental illness markedly impairs their quality of life, but also largely affect their family and friends. Furthermore, this is a major problem for society, which is negatively impacted by lost labor and growth and must shoulder the high costs associated with mental illness. Solution: A simple approach to booking the right psychologist Healper is a friendly guide and a booking platform that matches clients with psychologists. We have designed a comfortable, simple, and transparent user journey, that takes the client by the hand and helps him/her through therapy to mental health. Clients fill out a short questionnaire and are then matched with the best results from our database of more than 1,700 psychologists. Here, we find the psychologist who can statistically give the best treatment. Clients are presented with a prioritized list of three psychologists along with the reasons for the match. From this list, clients can choose which psychologist they like best, book a session, and pay. The platform continuously facilitates feedback from clients and their psychologists to improve the processing and precision of the matches.\n\nRead more about Healper","description_format":"text","description_chars":6312,"description_truncated":false,"requirements":{"experience_years_min":4,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Flexible schedule"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Digital Mental Health"],"lifecycle":[{"event":"open","at":"2026-10-11T07:28:46Z"}],"visa":[],"liveness":{"score":20,"band":"cold","label":"Long shot","p_open":0.6,"p_active":0.619,"p_room":0.55,"age_days":43,"expected_fill_days":30,"reasons":["seen:43","win:tail"],"computed_at":"2026-10-24T06:02:35Z"},"pay":null,"html_url":"https://alion.io/job/healper-senior-fullstack-engineer","json_url":"https://alion.io/job/healper-senior-fullstack-engineer.json","meta":{"generated_at":"2026-10-24T09:28:12Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":13741,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-25T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":2654321},"rest":"https://alion.io/mcp/rest/get_company?id=2654321"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhealper-senior-fullstack-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fhealper-senior-fullstack-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fhealper-senior-fullstack-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/healper-senior-fullstack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhealper-senior-fullstack-engineer"}]}
